Foreword

This is the ninth version of the Code of Practice developed by the City of London’s

Pollution Control Team to encourage the use of the best environmental options in

planning and managing construction and deconstruction (demolition) in the City of

London. The area is densely populated by residents, many types of business, and other

sensitive premises, all of which can be affected by construction work and associated

activities.

This Code meets one of the aims of the City Noise Strategy which is to mitigate and

minimise noise and noise impacts that could adversely affect health and well-being of

City residents, workers and visitors and to avoid noise and noise impacts that could have a

significant adverse effect.

This Code seeks to set out simply and clearly what constitutes acceptable site practice

within the City. It is intended to help developers, architects, engineers and construction

professionals to plan, cost and manage the environmental issues which frequently arise in

the industry.

In the City we encourage a flexible approach to addressing environmental problems. I

must emphasise that this needs early and, in some cases, frequent liaison with the officers

in the Pollution Control Team who should be consulted at all stages of project planning,

programming and operation, so that the best options for your site can be developed.

This ninth edition of the code generally revises and updates the eight edition. It contains

further guidance on the prevention of air pollution from activities on site, a minor revision

to the schedule of monitoring contributions and changes to standard Saturday working

hours.

Additionally, we encourage you all to apply, via our Considerate Contractors Scheme

(CCS), for the Environmental Award. This will recognise those sites/companies who

innovate to protect the Environment in the City each year.

The Code takes into account current best practice and new technology already adopted

by many sites in the City.

I hope you will find this guidance useful in planning and managing your site activities.

1 Introduction and Use

Introduction

1.1 At any one time there are many active deconstruction, construction and

refurbishment sites within the City of London. The work is essential in order to enable

the City to maintain its status as a world class centre of business and finance. Some

of the activities involved and listed in this document can often disturb and disrupt

neighbours and users of the surrounding area. To help Developers and their

Contractors minimise disturbance, the City of London has prepared this Code of

Practice detailing the standards to which they expect sites to be maintained and

operated.

1.2 The environmental impacts of construction work must be considered as early as

possible in the project. Where potential adverse impacts are identified, measures to

offset or reduce them should be incorporated into the project proposals at the

earliest stage and taken into account in the final cost. These matters must form part

of the ‘Scheme of Protective Works’ to be submitted to the Pollution Control Team

in the Department of Markets and Consumer Protection. We wish to encourage

best practice and new innovation in Environmental Matters and welcome all

companies/sites to take part in the CCS Environment Award.

1.3 Note: The term Contractor used within this Code of Practice includes Principal

Contractors, Construction Managers, Trade Contractors and other similar roles.

Ultimate responsibility rests with the Principal Contractor although the Developer (or

promoter of the project) will clearly have an interest in ensuring that works are

undertaken with minimum disruption.

Use and Application of the Code of Practice

1.4 This Code is intended as a guide to ‘Best Practicable Means’ but must not replace

consultation between developers, Contractors and regulators. Throughout all

stages of a project, discussion with the City of London is actively encouraged at the

earliest opportunity. The Code should be used by developers during the planning

application process as an informative document, allowing the developer to discuss

terms tailored to their specific development with the City of London. Developers

must ensure that Contractors are fully aware of this Code and its implications, in

particular the requirement for proactive and effective community Liaison and

Consultation (section 2).

1.5 Adherence to this Code will demonstrate a positive attitude and commitment

towards minimising environmental impacts and will be used as one of the main

methods of assessment within the City's Considerate Contractor Scheme. Many

consents granted by the City of London under Planning Acts will include conditions

which refer to the standards in this Code. Site specific Deconstruction and

Construction Schemes submitted under planning conditions will generally be

expected to reflect the relevant provisions of this Code.

1.6 The Code follows a methodical approach to construction works and sets standards

to be followed. Not all parts of this Code will apply to every construction project.

However, the City will expect all Contractors to comply with the spirit of the Code,

Ninth Edition January 2019

1

Pollution Control Team: 020 7606 3030

with appropriate provisions being applied to the site at all times. This should allow

local residents and businesses to continue operating with minimal disturbance.

1.7 Where two sites (or more) are operating in close proximity to each other the impact

of all operations on neighbours will be taken into account when applying controls

to mitigate any environmental effects. It will be expected that arrangements for

liaison between sites, as well as the City, are made by the Contractor at the

beginning of projects to ensure that the joint impact from the work of all sites in the

locality is kept to a minimum.

1.8 Although this Code gives an outline of legal requirements, it is not an authoritative

statement of the law. Where necessary in accordance with its policy statement on

enforcement, the City of London will not hesitate to enforce the statutory powers

they have. A list of relevant guidance and legislation are included as Appendix A.

1.9 There is generally a good level of compliance across the City with this Code, but the

density of development, high level of activity, and conflicting needs of different

communities occupying an extremely limited area mean that the impacts of non-

compliance can be particularly severe. This Code makes provision for a more

proactive approach to monitoring by City Officers in order to ensure better long

term environmental management and help mitigate adverse construction impacts

more effectively.

2.0 Appendix L sets out contributions which will be sought by the City on certain

developments to assist improved monitoring and liaison, and which may be

provided for in site specific Deconstruction and Construction Schemes submitted

under planning conditions.

2 Community Liaison and Consultation

Summary:

The Contractor needs to:

•

demonstrate ‘best practicable means’ by contacting the City of London

well in

advance of

works commencing to discuss the proposed works and the scope of

liaison and ‘Scheme of Protective Works’ to be submitted for protecting nearby

residents and commercial occupiers (hereafter referred to as neighbours);

• identify neighbours and interested parties (including where appropriate Ward

Members) and consult with them before finalising the Scheme of Protective Works;

• maintain dialogue and information exchange with the City of London’s Pollution

Control Team, neighbours and interested parties throughout the proposed works;

• respond quickly to complaints and resolve where practicable; and

• ensure neighbours and interested parties are kept informed of works as they progress

and are consulted where necessary.

Scheme of Protective Works

2.1 Prior to work commencing on each stage of the development, the Contractor must

contact the City of London’s Highways Division and the Pollution Control Team, in

order to:

• agree the scope of the ‘Scheme of Protective Works’ to be submitted; and

• identify the scope of community liaison and consultation.

2.2 The Contractor must demonstrate ‘Best Practicable Means’ (BPM) and create a

‘Scheme of Protective Works’ for protecting neighbours. As part of this Scheme, the

Contractor is expected to have and apply appropriate liaison and consultation

approaches to minimise the environmental impact on neighbours.

2.3 The scope of the Scheme and extent of liaison will be site dependent, having

regard to the scale of works and the potential for disruption to neighbours. Figures

2.1, 2.2 and 2.3 will be used to guide the scope required. Figure 2.4 is a guide to the

information which may be required in the ‘Scheme of Protective Works’.

2.4 For Category A, B and C sites, throughout the construction/deconstruction works,

regular dialogue between the Contractor and the City of the London should take

place and meetings with the City may be held. The names and contact details of

appropriate site personnel must therefore be forwarded to the Pollution Control

Team at the earliest opportunity to facilitate liaison. A list of useful City of London

contact names and telephone numbers is included in Appendix B. The liaison

requirements for all sites are set out in figures 2.1 to 2.5.

Liaison and Consultation Strategy

2.5 The Liaison and Consultation Strategy should identify all neighbours and specify

individuals and groups who may be affected by, and consulted with, regarding

activities at the site. The strategy should include the contact details and programme

for engagement. The Contractor should therefore identify the following:

• City of London Ward Member(s) for the site; who can be identified via the City

of London Website at:

http://democracy.cityoflondon.gov.uk/mgFindMember.aspx or by contacting

the Pollution Control Team. A copy of the Ward boundaries can be found in

Appendix K and an interactive map can be found at:

https://www.mapping.cityoflondon.gov.uk/geocortex/mapping/?

viewer=compass&runworkflowbyid=Switch_layer_themes&LayerTheme=Show

%20the%20Ward%20Boundaries%20layers

• All neighbours and premises which may be affected by the site’s activities,

including:

- any residential properties;

- hotels, hostels and hospitals;

- offices;

- lunchtime catering premises;

- public houses;

- those affected by party wall/shared party element works (see sections 3.40-

3.42 for guidance);

- Places of worship

- Community Centres

• Local Community Groups such as the Barbican Association, Castle Baynard

Residents and Smithfield Trust; and

• Other interested parties (e.g. other construction / deconstruction sites in close

proximity, utility and street works in the area and any events such as the Lord

Mayors Show or road races).

2.6 Identification of residential premises

Reference should be made to the Residential Streets map (Appendix J), which

identifies residential areas within the City. New residential developments are

continually appearing, so the Pollution Control Team should be consulted in order

to obtain the most up to date information. For this reason, the Contractor should

also re-evaluate the area in close proximity to the site from time to time. This will

enable the Contractor to identify new groups or individuals who may be affected

by the site’s activities.

2.7 With reference to Figure 2.5 below, the Liaison and Consultation Strategy should

include:

2.8 Initial Consultation

Ninth Edition January 2019

6

Pollution Control Team: 020 7606 3030

Prior to each project stage, provide a briefing/presentation of the ‘Scheme’

(detailed above) to the Ward Member(s), residents, Local Community Groups,

businesses and other individuals identified. Briefings should include:

• Details of the ‘Scheme of protective Works’ in a readily understandable

form;

• formal presentation, question and answer session or drop in sessions;

• information regarding how the works will enhance and benefit the local

environment for neighbours; and

• Opportunity to provide feedback on the proposed works should be

invited and responded to in writing; where practicable, amendments to

the Scheme should be made to address concerns raised. The finalised

Scheme should be provided to the City’s Pollution Control Team and

where requested, the Ward Member(s), neighbours and interested

parties.

2.9 On-going Communication

• Plans for at least fortnightly communication (or as otherwise agreed) with

neighbours and interested parties (identified above), for example by

newsletter, in order to keep neighbours informed about current progress and

planned works. The newsletter should be timely to allow neighbours time to

plan around the works. It should contain the information suggested below,

together with details of the Pollution Control Team contact:

- The location of the planned works;

- The type of planned works which are anticipated to give rise to

effects on adjacent residents;

- The duration of the planned works and the periods within which works

will be undertaken (i.e. whether during normal working hours, during

the evening or overnight);

- The anticipated effects of the planned works;

- The measures to be implemented in line with the Scheme of

Protective Works to mitigate the impact of the planned works;

- Contact details for enquiries; and

- Complaints Procedure.

• A display board should be erected outside the site, which as a minimum shall

identify key personnel, contact addresses, web site and telephone numbers,

including complaint contact numbers. Additional information should include

details of the scheme and its progress.

2.10 Other Communication

• The Contractor should appoint a responsible person to liaise with the City,

neighbours and interested parties in order to keep them informed of matters

likely to affect them. Good relations can be developed by keeping

neighbours informed of progress and by responding to complaints quickly

and fairly.

• Site Hours Variation Request Procedure (as per paragraph 3.10) to be

followed for ANY works outside the ‘standard hours’ or within the ‘quiet

hours’;

• Arrangements should be put in place for notifying or alerting neighbours in

advance of additional unplanned noisy works, where applicable;

• Feedback should be requested from neighbours throughout the project and

at the end, in order to allow modification of activities to reduce impact;

Complaints Procedures

2.11 The Contractor will establish a system and procedure for dealing with enquiries and

complaints from the public.

2.12 Contact numbers, email and postal addresses for the enquiries and complaints

system will be displayed on signs around the construction site and will be published

on the website and newsletters.

2.13 Where complaints are made, the Contractor is expected to respond by

investigating the complaint quickly and sympathetically, taking action to resolve

the problem where the complaint is justified. If no resolution can be found the

complaint should be referred to the City of London. A Contractor’s response to

complaints is an important criterion when evaluating the performance of the site for

the Considerate Contractor Scheme.

2.14 The Contractor must maintain a designated complaints/incidents logbook or

register covering:

• the nature of the complaint

;

• the cause; and, where appropriate,

• th

e remedial action taken

.

.15 The City may request to see the complaints/incidents logbook at any time.

2.16 Complaints received by the City of London will be investigated. This will involve

discussions with the Contractor and, if appropriate, monitoring or surveillance.

Enforcement action may be taken if the complaint/s are justified and sufficient

steps have not been taken by the Contractor to resolve matters.

Ninth Edition January 2019

Pollution Control Team: 020 7606 3030

Other Consultation

2.17 The City of London must be told in advance of any unusual activities including

planned out-of-hours working. The Site Hours Variation Request Sheet (Appendix H)

must be completed and e-mailed to the Pollution Control Team at least 5 days

before the activity is to take place. Approval or the reasons for refusal will be

countersigned and e-mailed back. Unless approval is given and the sheet is

available for inspection, an Officer attending the site, in response to a complaint,

will require the noisy work to stop.

2.18 The Pollution Control Team must be supplied with a current 24-hour call out number

that will be answered in the case of a complaint or an emergency. It is also

recommended that Contractors contact the City of London Police service to

ensure a security assessment is carried out.

2.19 Where construction activities are being undertaken on two or more sites in close

proximity, regular meetings should be arranged and attended by representatives

from each site and the City of London in order to minimise cumulative impacts.

Items for discussion may include:

• activities to be undertaken;

•neighbour liaison;

• requirements for road closures; • monitoring results;

• out of hours work;

•requirements for mitigation.

2.20 The appropriate body must to be contacted with regard to wastewater generated

from site activities which is classified as trade effluent. See section 7.

2.21 Contact must be made with the City of London Drainage Services Group (020 7332

1105) or Thames Water Utilities (0800 3169800) before any work is undertaken on

connections to sewers or drains running under the public highway. See Section 7.

2.22 The Contractor must ensure that the Department of Built Environment

(Development Management) has been contacted via 020 7332 1710 to establish

whether the site contains a listed building, scheduled ancient monument or

archaeological remains, and what specific requirements are included in the

planning permission, listed building consent or conservation area consent. Details

regarding scheduled monument consent should be obtained from Historic England;

their contact number is 020 7973 3000. See Section 8.

2.23 The Contractor must ascertain whether any trees on the site or in immediate area

are either protected by Tree Preservation Orders or fall within a Planning

Conservation Area prior to works starting. This may be done by contacting the

Department of the Built Environment (Tree Officer) on 020 7332 1708. See Section 8.

2.24 Prior to commencement of works on-site, an ecological survey should be

undertaken by a qualified professional to confirm the absence of birds, bats and

any other protected species which may be nesting/roosting within buildings or

vegetation. If present, appropriate mitigation measures should be undertaken

following consultation with the City’s Department of Open Spaces who can be

contacted on 020 7332 3505. See Section 8.

Considerate Contractor Scheme

2.25 The Considerate Contractor Scheme (CCS), pioneered by the City of London in

1987, aims to encourage building and civil engineering Contractors working

adjacent to the City's streets to carry out their operations in a safe and considerate

manner, with due regard to passing pedestrians and road users. Details are set out

in Appendix C of this Code. As part of the scheme, all Contractors will be evaluated

by the Pollution Control Team for their level of co-operation and compliance with

this Code of Practice.

3 Noise

Summary:

The Contractor must:

• contact the Pollution Control Team to agree the working hours and methods to be

used which may generate noise and vibration prior to the commencement of any

work on site (see Section 2 – Scheme of Protective Works);

• Adhere to ‘standard’ hours for noisy site work and ensure that best practicable

means are used to mitigate noise and vibration impacts on neighbours;

• Observe ‘quiet hours’ where City business activities may be affected by noise or

vibration;

• ensure that if work is planned to take place outside the ‘standard’ hours, prior

approval is obtained from the Pollution Control Team using the ‘Site Hours Variation

Request’ procedure

Introduction

3.1 The high level of intensive development in the City, including major office

redevelopments in the east and infrastructure projects, can have significant

environmental impacts on occupiers of nearby noise sensitive premises. Protecting

City businesses, residents and other noise sensitive premises (e.g. schools) from noise

and vibration impacts of construction sites is essential to the City’s continuing

reputation as an excellent place to live, work and to do business.

3.2 This Code of Practice is a notice of the City of London’s general requirements under

Section 60 of the Control of Pollution Act 1974. The Contractor may also be

informed of additional requirements during consultations with the City of London.

3.3 Complaints about excessive noise disturbance found to be justified may result in a

Section 60 notice, under the Control of Pollution Act 1974, being served by the City

of London. This will generally require the Contractor to adhere to these quiet

working hours.

Hours of Work

3.4 Prior to commencing work, Contractors must contact the Pollution Control Team in

order to agree hours of work. If no-one is disturbed by works then 24-hour working

may be considered; however, such circumstances are rare in the City. Where

residents and commercial activities are significantly affected or are likely to be

affected, the standard times of operation will be imposed.

3.5 Standard Hours

‘Standard’ hours permitted for noisy work will normally be the following:

• 08:00 - 18:00 hours (Monday to Friday);

• 09:00 - 14:00 hours (Saturday);

• No noisy working is permitted on Sundays, Bank or Public Holidays.

Ninth Edition January 2019

11

Pollution Control Team: 020 7606 3030

3.6 Reduced Impact Hours

The City also requires time restrictions on noisy works to reduce noise disturbance to

businesses. These times are known as ‘reduced impact hours’ which are:

• 10:00 - 12:00 (Monday to Friday);

• 14:00 - 16:00 (Monday to Friday).

‘reduced impact hours’ are put in place to give nearby commercial occupiers at

least 4 hours without noisy working from street and construction sites during the

working day. These periods may be subject to variation in particular circumstances,

for example during lunchtimes, adjacent to eating places or businesses where the

majority of trade is carried out at lunchtimes.

3.7 Work outside standard hours and during reduced impact hours

Outside ‘standard hours’ and during ‘reduced impact hours’ the following noise

generating activities will not usually be permitted where the activities are likely to

cause disturbance:

• Cutting using power tools;

• Breaking out using power tools;

• Other noise generating activities, depending on the specific location of site

and neighbours.

• The use of impact fasteners;

• The loading of heavy materials;

• Other noisy activities, depending on the specific location of site and

neighbours, deemed unacceptable by Environmental Health Officers.

Where there is no disturbance from these activities it is likely that variations will be

permitted, see 3.10 below.

3.8 Noisy work outside ‘standard hours’ or during ‘reduced impact hours’ will be

considered in order to support the City’s businesses and also the needs of local

neighbours e.g. proximity to restaurants, places of worship or residential properties.

3.9 ANY works outside the ‘standard hours’ or any noisy activities within the ‘reduced

impact hours’ can only be undertaken with the approval of the City using the Site

Hours Variation Request Sheet (Appendix H). Approval will be conditional on the

Contractor submitting the following:

• Details of site and out of hours contacts

• Details of site operations and location

• Dates and proposed hours

• Reasons and justification for the request

• Proposed plant to be used

• Predicted noise levels at sensitive locations

• Mitigation measures

• Neighbours affected and copies of written notifications.

Variations will be approved for works where impacts can be demonstrated to be

low, in locations where there are no affected neighbours or for safety, logistics or

engineering reasons. Variations may be refused if the impacts on neighbours are

considered high and cannot be mitigated or previous variations have not been

fully complied with.

3.10 Where, in the opinion of Environmental Health Officers, structurally transmitted noise

adversely affects neighbours, it will be barred between 09:00 - 17:00 hours. For

complex sites with a neighbour mix including residential, retail, and commercial

properties, advance negotiation with all parties and the Pollution Control Team is

Ninth Edition January 2019

12

Pollution Control Team: 020 7606 3030

expected of the Developer/Contractor, as restrictions may have significant

implications for cost and timing of the project.

Noise and Vibration Monitoring Regimes and Limits

3.11 The City requires Contractors to undertake and submit predictions of noise and

vibration levels at identified locations and any identified sensitive receptors. Regular

intelligence-led monitoring of noise and vibration levels is also expected to be

undertaken by looking at the work programme and identifying aspects likely to

cause significant noise/vibration. Receptor points are to be agreed with the City of

London prior to initiation of predictions and monitoring. Results should be compared

against suitable baseline data as a useful means of:

• Controlling noise and vibration, and identifying problems at an early stage (it is

particularly valuable to carry out monitoring during the early stages of a

project);

• providing an objective basis for evaluating complaints; and

• safeguarding Contractors against claims of damage.

3.12 Prior to commencing work, it is essential to undertake monitoring of ambient noise

levels around the site at sensitive neighbours (this should be agreed with the City

Pollution Control Team). This will provide baseline data for comparison with levels

present during the works. This baseline assessment should be submitted to the

Pollution Control Team. A baseline vibration exercise will be unnecessary unless

neighbours are clearly affected by any existing source of substantial vibration e.g. a

tube line.

3.13 Where there are party walls or neighbours are otherwise directly attached to

elements of the site, the noise, vibration and structural implications of the proposals

will require individual and detailed evaluation.

3.14 In some circumstances, the Pollution Control Team may require continuous

monitoring combined with a real-time alarm system, with details to be agreed on

an individual basis. Informal site boundary walk about to monitor noise as

experienced by neighbours is highly recommended to understand the impact the

site may be having.

3.15 Noise measurements should ideally be taken with a Class I Integrating Logging

Sound Level Meter calibrated (before and after) with a Class I Acoustic Calibrator.

L

Aeq

and L

AFmax,

noise levels should be recorded (as a minimum) together with a

record of all events potentially affecting the noise level at the time of monitoring.

3.16 Note: The period over which the L

Aeq

parameter should be averaged must be

agreed with Environmental Health Officers.

Noise Limits

3.17 The suitability of specific noise limits is highly dependent upon the individual

situation. The factors to be considered include:

• The characteristics of the noise and its potential effect on the neighbours;

• Baseline ambient noise levels; and,

• The nature and duration of the works.

3.18 In addition, following complaints, specific noise levels may be set to prevent

speech interference in offices and loss of trade.

Ninth Edition January 2019

Pollution Control Team: 020 7606 3030

3.19 The City of London expects noise from the site to be controlled to an acceptable

level. In the City environment this can be a difficult balance and ‘best practicable

means’ must be applied to reduce noise and vibration as far as possible.

3.20 Noise levels within businesses during noisy periods must enable workers to carry out

conversations, both face-to-face and on the telephone, and allow normal business

to be conducted. It is considered that an internal noise level of 65 dBA or above is

likely to cause annoyance and interference to all occupiers (dependent on the

noise characteristics).

3.21 Such noise should be restricted to hours outside the normal working day of 09.00 –

17.00. Timings of works with noise levels exceeding 65dBA affecting all City

occupiers should be discussed and agreed with Environmental Health Officers prior

to commencing.

Vibration Limits

3.22 When carrying out works which may produce vibration, all potential receptors must

be considered, with particular attention to be paid to the following:

• Occupiers and users of

• IT related issues;

buildings

• Cosmetic or structural damage to buildings

• Hospitals or laboratories

or heritage sites.

3.23 People’s response to perceptible vibration is accentuated by their fear of building

damage. Suitable guidance upon the levels of vibration, which may cause building

damage, can be found in BS 7385-2:1993.

3.24 Guidance relating to the potential effect upon the operation of computers and

other relatively sensitive equipment can be found in BS 5228-2:2009+A1:2014.

3.25 Complaints of vibration are usually concerned with fear of the unknown and the

potential effects of relatively low levels of vibration in buildings. This problem is best

addressed by:

• Liaison with all parties potentially affected, with explanations given of precisely

when they are likely to be affected by specific activities;

• Monitoring affected parties to reassure occupants as to the relative levels of

vibration compared with building effect (BS 7385-2:1993).

3.26 Vibration meters should preferably record 3 orthogonal Peak Particle Velocity

values (15 minutes of 10 second or shorter samples). Where complaints are

received, the Contractor/client should consider the need for monitoring at

neighbouring premises.

Working Methodologies, Noise and Vibration Control Measures

General methodologies

3.27 In addition to working hours and community liaison, all works must be carried out in

accordance with BS 5228-1:2009+A1:2014 and BS 5228-2:2009+A1:2014. All works

must employ Best Practicable Means as defined by Section 72 of the Control of

Pollution Act 1972 to minimise the effects of noise and vibration. The City must be

Ninth Edition January 2019

14

Pollution Control Team: 020 7606 3030

satisfied that all means of managing and reducing noise and vibration, which can

be practicably applied at reasonable cost, have been implemented.

3.28 A written evaluation of methodologies used must be made available to the City of

London and include justifications with regards to the minimisation of noise and

vibration (see section 2 and figure 2.4).

3.29 The City considers the off-site prefabrication or preparation of as many building

elements and materials as possible an essential requirement for Best Practicable

Means, in particular for the cutting of decking and steelwork.

3.30 Where appropriate, the following measures to minimise noise and vibration levels

should be adopted:

• Employing only modern, quiet and well-maintained equipment (all equipment

must comply with the EC Directives and UK Regulations set out in BS 5228-

1:2009+A1:2014);

• Using low impact techniques, such as demolition munchers and bored or

hydraulically-jacked piling rigs;

• careful planning of the sequence of work in order to minimise the transfer of

noise/vibration to neighbours;

• using fully silenced modern piling rigs selecting pressed in methods or auger

over higher impact methodologies

• Careful operation of the piling rig so there is no reversing of the Kelly/auger

bars;

• using electrically powered equipment run from the mains supply;

• use of screws and drills rather than nails for fixing hoardings etc;

• use of an alternative to percussive drills / hammer where possible

• use of plasma cutters where cutting on site is the only alternative

• careful handling of materials & waste such as lowering rather than dropping

items;

• taking steps to isolate the deconstruction works from sensitive neighbours, in

order to minimise the transfer of vibration and structure borne noise;

• erection of acoustic screens or enclosures wherever possible;

• avoidance of unnecessary noise (such as engines idling between operations,

shouting, loud radios or excessive revving of engines) by effective site

management.

• Concrete pours and finishing must be planned to avoid overruns past the

standard hours, the pour size and concrete workability must be considered.

The Contractor must enter into a written protocol with the concrete supplier

regarding timing of deliveries to ensure works can be completed within the

permitted hours.

• The position, location and acoustic shielding of any concrete pumps must be

agreed with the Pollution Control Team.

• Audible alarms must be broadband sound, including reversing alarms and

other equipment such as mobile elevated work platforms.

• Pile breaking-out, pile reduction work, and concrete break-out and removal

must be carried out, where reasonable and practicable, using low impact

techniques such as bursting, munching, cutting or bending, if impact methods

must be used then works should be undertaken within a portable acoustic

enclosure. The enclosure shall be three-sided with a roof or such other

acoustic enclosure.

• As an alternative to breaking in situ, remove larger sections by lifting them out

and breaking them down off site.

Ninth Edition January 2019

15

Pollution Control Team: 020 7606 3030

3.31 Where control at source is not practicable or adequate, the distance between

noise/vibration sources and sensitive neighbours should be maximised and the

transmission path interrupted, with options considered in the order of source-

pathway-receptor. Where practical this can be achieved by:

• Siting of stationary plant and loading/unloading areas;

• erecting impervious hoardings, of at least 5 kg/m

2

surface density, where

possible higher than the line of sight to neighbours;

• leaving building façades and boundary walls intact as long as possible during

demolition and boarding/bricking up windows;

• the use of existing non-sensitive structures as shields;

• the use of temporary structures; and

• cutting of transmission pathways for vibration.

3.32 In addition to mitigation strategies above, a Liaison and Consultation Strategy (as

detailed in section 2) should be implemented as an essential element of the Best

Practicable Means to minimise the effects of noise and vibration.

Vehicle Movements, Deliveries, Loading and Unloading

3.33 Vehicle movements, deliveries, loading and unloading can cause considerable

noise and disruption to neighbours as a result of the following:

• reversing beacons;

• running engines; and

• noisy material being loaded and unloaded

3.34 All loading, unloading and deliveries of materials and plant to the site and removal

of waste should, where possible, be carried out within normal site working hours.

Any early morning or evening deliveries must have approval from the Pollution

Control Team. This must be requested using the copy of the Site Hours Variation

Request Sheet (Appendix H).

3.35 All vehicle movement alarms and reversing beacons must be broadband sound

where practicable, engines must be switched off when not in use and unloading

conducted with care. The site layout should be designed to minimise potential

effects on neighbours. A competent banksman should be employed to provide

assistance to vehicles accessing and leaving the site, thereby ensuring minimal

traffic disturbance and pedestrian safety.

3.36 Vehicle movements should be planned to ensure that lorries do not arrive or depart

outside standard hours. No daytime or night-time parking of lorries will be permitted

outside agreed areas.

3.37 Where appropriate, deliveries should be arranged on a just-in-time basis in order to

prevent vehicles queuing outside site.

3.38 Appendix F of this code summarises the City of London's traffic management

requirements for vehicle movements, site deliveries, street closures, crane

operations and abnormal loads. This can be copied for use by Sub-Contractors and

others.

Party Wall work

Ninth Edition January 2019

16

Pollution Control Team: 020 7606 3030

3.39 Work to party walls and major works in partially occupied buildings will be strictly

controlled, and are usually barred between 09:00 and 17:00 hours when noise

and/or vibration could be transmitted to neighbouring properties and businesses.

Working hours for Party Wall work must therefore be agreed with the City’s Pollution

Control Team prior to works commencing.

3.40 Vibration monitoring should be considered to reassure neighbours and assist in

demonstrating that levels do not exceed those which may cause structural

damage to adjoining buildings. Complaints relating to vibration can cause

considerable delays, particularly during demolition piling and ground work phases

of construction activities. Noise should also be considered to assist in determination

of acceptable levels.

3.41 Where works are carried out close to, or on, a party wall, The Party Wall Act 1996

may apply. The Contractor must consider all aspects of this Act and allow sufficient

time to comply with it.

Scaffolding and Gantries

3.42 Scaffold erection or dismantling can cause disturbance to site neighbours. All works

must be undertaken in accordance with the Department of Built Environment’s

Highways Division Guidance Notes for Activities on the Public Highway and be

subject to a licence under the 1980 Highways Act. Subsequent erection and

dismantling activities must be agreed with the Pollution Control Team, and comply

with prescribed times.

3.43 Appendix D sets out detailed information on the requirements of the City for

scaffolding and gantries.

Cranes, Lifting of Heavy Equipment, and consequent Road Closures

3.44 The erection of fixed cranes, rigging, and use of mobile cranes on the highway and

lifting of heavy equipment often has to be undertaken outside normal working

hours. All these street-based activities require prior consent from both the Highways

Division and the Pollution Control Team. Although it is normally the crane

company’s responsibility to obtain prior approval for the works, the Contractor

should ensure this has been done.

3.45 The Pollution Control Team’s approval for the work is required to ensure that all

plans are appropriate for the location, and that steps have been taken to mitigate

any disturbance to commercial or residential neighbours. The application for this

must be accompanied by a lifting plan.

3.46 The correct procedure involves the following:

• See: highway licences

page to ensure all relevant authorisations have been

obtained

• Telephone the Pollution Control Team to agree the outline proposals (020 7606

3030).

• The ‘mobile crane environmental health authorisation notice & structures

notification form’ (Appendix I), together with a lifting plan, should be fully

completed and returned to the Pollution Control Team for scrutiny/approval.

• Once received, the completed application form will be checked, any

necessary amendments agreed with the sender, and returned to the applicant

Ninth Edition January 2019

17

Pollution Control Team: 020 7606 3030

with the appropriate signature. This can then be presented to the City’s Street

Management Office at a previously agreed appointment (020 7332 3553).

3.47 Note - The part of Appendix I relating to ‘structures authorisation’ must also be

signed by the crane company’s representative. It is the crane operators

responsibility to check whether there are any underground ‘structures’ either under

or in the vicinity of the highway where the crane operation is sited - see Appendix F

for full details.

3.48 Crane oversailing must be agreed with the City of London and/or site neighbours.

Under section 177 of the Highways Act 1980, site cranes require a licence if the jib

at any point extends over the public highway. Application for this licence should be

made to the Department Built Environment’s Highways Division. A charge may be

levied for oversailing the public highway.

4 Air Quality

Summary

The Contractor must:

• Submit a Scheme of Protective Works which includes an Air Quality Dust Management

Plan (AQDMP) which details techniques to be adopted that ensure the air quality in

the City of London is not adversely affected by activities at and associated with the

development site.

• The AQDMP should be produced in line with the requirements of this section which

includes a consideration of:

• Summary of works that may impact air quality

• Complaints and incidents procedure

• Staff training relating to air quality matters

• Site Plan

• Air quality monitoring considerations and trigger levels

•

Machinery and equipment used on site

(NRMM compliance / minimised

generator use / concrete crushers/ no-idling policy)

• Working methodologies and emission controls to be employed

Introduction

4.1 Under Part IV of The Environmental Act 1995 and the Government’s UK Air Quality

Strategy, Local Authorities are required to work towards achieving national air

quality objectives. The City of London has some of the worst air quality in the

Country and has been declared an Air Quality Management Area for PM

10

(fine

particles) and nitrogen dioxide.

4.2 The UK is facing the prospect of large fines from the European Commission for

failure to meet air quality Limit Values. Recent studies have demonstrated that poor

air quality and dust have a significant impact on public health in London, with the

equivalent of over 10,000 premature deaths in London in 2010 attributable to poor

air quality; this issue is now therefore of the highest priority.

4.3 Construction and deconstruction sites in the City are therefore expected to meet

the highest possible standards for control of air pollution and dust.

4.4 In July 2014, The Greater London Authority (GLA) published the Supplementary

Planning Guidance document (SPG): ‘

The Control of Dust and Emissions During

Construction and Demolition’. In order to mitigate negative impacts on air quality in

the City, the construction and deconstruction industry is expected to employ, as a

minimum, methods detailed in the GLA SPG (and subsequent revisions) and

detailed in this section. As additional best practice and case studies become

available, they will be available at:

www.cityoflondon.gov.uk/airqualityplanning

Ninth Edition January 2019

Pollution Control Team: 020 7606 3030

Air Quality Risk Categorisation in the City Environment

4.5 Where an Air Quality Impact Assessment is created and submitted at the planning

stage for approval, it may include an Air Quality (Dust) Risk Assessment (AQDRA)

prepared by a competent person. The GLA’s SPG (2014) provides guidance with

regard to which sites the GLA consider high risk.

4.6 The risk assessment detailed in the SPG requires a detailed understanding of the

project and its effect on receptors. The built up nature of the City, unpredictable air

flow and its poor air quality means even small scale deconstruction/construction

projects can have an adverse impact on air quality. For this reason, all projects will

be expected to implement all possible mitigation measures and an explanation

provided where they are felt not to be required.

Air Quality Monitoring

4.7 The GLA’s SPG suggests that continuous monitoring for particulate matter is

required at high risk sites. However, reliance on the results of continuous monitoring

as an indicator that the site is doing all it can to reduce emissions is not sufficient

due to the density and wind direction factors in the City mentioned above. As such,

a greater emphasis should be placed on control measures such as damping down

and site management (e.g. no-idling policy and NRMM compliance, see sections

below).

4.8 Continuous monitoring positioned between construction sites and sensitive land

users, such as buildings with openable windows, outside amenity and residential

developments, is beneficial with regard to providing assurance to neighbours;

however, its reliance as an indicator of good site management is limited due to the

above. Appendix 8 of the GLA’s SPG provides details regarding different types of

monitoring.

4.9 Continuous air quality monitoring will normally be required on large sites adjacent

to sensitive premises such as residential properties, schools and St Bartholomew’s

hospital. This may include dust slides for assessing nuisance dust and real time

monitoring to assess PM

2.5

and PM

10

. A site will not normally be required to monitor

nitrogen dioxide.

4.10 Real time monitoring may involve setting an alarm to alert the site manager if levels

of PM

10

go above a set threshold. The threshold value, type and location of any

monitoring equipment should be agreed with the Pollution Control Team in

advance. The threshold value is normally initially set at 150µg/m

3

for PM

10

over a 15

minute period, with the level being reviewed periodically.

4.11 Regular patrols outside the site perimeter during potentially dusty works are

required. This is to look for visual evidence of dust releases off site and to take

appropriate action where it is identified. The Contractor shall take any necessary

measures to prevent nuisance/adverse effects to people’s health.

Ninth Edition January 2019

20

Pollution Control Team: 020 7606 3030

Machinery and Equipment on Site (GLA SPG Chapter 7)

4.12 Non-Road Mobile Machinery (NRMM): NRMM are often fueled by diesel and

therefore give rise to nitrogen dioxide and particulate emissions. Consequently, the

need, size and choice of NRMM should be carefully considered. Before sourcing

diesel plant, consideration needs to be given to low and zero emission plant, such

as electric or hybrid MEWPs. Where diesel plant is employed it should adhere to the

NRMM policy below as a minimum. Notwithstanding the policy size requirements,

ALL diesel plant should be the lowest emission solution available.

The NRMM policy is set out in the GLA’s Dust and Emissions SPG. Since 1 September

2015 NRMM with a net power between 37kW and 560kW used in the Central

Activity Zone are required to meet the standards set out below. This applies to both

variable and constant speed engines for both NOx and PM. These standards are

based upon engine emissions standards set in EU Directive 97/68/EC, and its

subsequent amendments.

NRMM (within the above kW range) used on any site within the City are required to

meet Stage IIIB of the Directive as a minimum. From September 2018, this

requirement changes to Stage IV. Any amendments of the policy and guidance

must be adhered to. Where the above commitments cannot be met the matter

should be discussed and agreed with the Environmental Health Officer.

Prior to the commencement of any works, all developments within the City must

register relevant NRMM online at https://nrmm.london/register. There are a small

number of permitted exemptions to the above, and more details of this or updates

to the overall NRMM policy requirements, which should be adhered to, can be

found at the website: www.nrmm.london.

The NRMM should be maintained and operated in accordance with the

manufacturers guidelines so as to achieve the required emission standard; this

includes the grade of fuel used.

In order to demonstrate NRMM compliance, best practice includes using stickers on

machinery to show engine stage and the use of a spreadsheet to detail all

equipment on site, with photos and a compliance reference; such best practice is

encouraged on City sites.

4.13 Generators: Diesel generators give rise to nitrogen dioxide and particulate matter

emissions. The use of generators to provide electricity on site should therefore be

avoided wherever possible. This can be avoided by ensuring an electrical supply for

the site is secured well in advance of works.

Where generator use cannot be avoided, it should be a lower emission solution,

such as hybrid, gas or hydrogen technology. Where diesel is used, the newest Euro

standard engine should be used (in accordance with the NRMM policy), with a

lower emission solution that incorporates battery storage technology. This reduces

generator size and running hours, cuts fuel consumption, emissions and noise. The

use of hydrogen technology for lighting towers and site cabins rather than

generators should also be considered.

4.14 Concrete Crushers: The use of concrete crushers will not generally be sanctioned in

the City because of the potential to cause dust and nuisance to neighbours.

Ninth Edition January 2019

21

Pollution Control Team: 020 7606 3030

However, the City of London will allow the use of city crushers to prepare material

for piling mats and ramps, as this reduces the number of vehicle movements

associated with the site. Any crushing plant would have to be authorised under the

Environmental Protection Act 1990. Appropriate measures, such as enclosing the

plant and built in water sprays would have to be used at all times.

4.15 Emission management and idling engines: Machinery must be appropriately sized

and sourced for use, well maintained and used in accordance with manufactures

guidelines. Machinery and vehicles must not be left idling either on site or waiting

for access to the site as this gives rise to unnecessary air pollution. It is a requirement

of Regulation 98 of the Road Vehicles (Construction and Use) Regulations 1986 (as

amended) for drivers to switch off their engines in parked vehicles. Failure to turn off

an idling engine if requested may lead to a Fixed Penalty Notice being issued under

the Road Traffic (Vehicle Emissions) (Fixed Penalty) (England) Regulations 2002).

Scheme of Protective Works and Air Quality Dust Management Plan (AQDMP)

4.16 A Scheme of Protective Works will need to be submitted to the City Corporation

and approved prior to works commencing on-site; it should include an Air Quality

and Dust Management Plan (AQMDP).

4.17 The AQDMP should detail measures to reduce on site emissions and a consideration

of utilising dust and emission reduction measures detailed below. It should also be

kept under review so that changes to the timetable and potential emissions can be

mitigated.

4.18 The AQDMP should be produced prior to any demolition or construction works,

agreed with the City Corporation and should contain details of the following:

• Summary of the work to be carried out and an inventory and timetable of all

dust and NOx air pollutant generating activities;

• Liaison and consultation strategy relating to works which may impact on air

quality;

• Complaints and incidents: methodology for recording action taken in response

to incidents;

• Staff and training: The identification of a trained and responsible person on site

for air quality and the training schedule for all staff e.g. toolbox talks relating to

idling engines;

• A site plan(s) showing:

o sensitive receptors

o site layout and access (with wheel check and wash facilities shown)

o air quality monitoring locations

o site equipment, including generator location

o location of water for damping down

o fuel stored on site

o reference to the CLP which contains proposed haulage routes and vehicle

waiting areas;

• Monitoring: Summary of monitoring methods (if applicable), trigger levels and

procedure for mitigation when exceeded;

• Machinery:

- confirmation that NRMM compliant equipment will be sourced and

registered on the GLA website;

- a commitment to sourcing power for the site which does not involve diesel

generators;

Ninth Edition January 2019

22

Pollution Control Team: 020 7606 3030

- details regarding concrete crusher use;

- emission management plans which includes no-engine idling, both on and

off site; and

• working methodologies and control measures should be included in the

AQDMP for all relevant activities which may affect air quality. The controls

implemented should include those detailed in sections 4.19-4.29 below. The

scheme should consider the entire lifetime of the project and sequence of

works.

Working Methodologies and Control Measures (SPG chapter 5)

4.19 Activities undertaken on site must be done so with methodologies which reduce

the likelihood of dust generation and the worsening of air quality. With reference to

the Mayor’s SPG, the phases of works which could create emissions that affect

human health and the environment are:

• Demolition

• Earthworks

• Construction

• Trackout

4.20 The following control measures should be incorporated for the relevant phases. The

AQDMP can state it will adhere to this code, rather than detail all methods that will

be adopted; however, where measures are not adopted, in discussion with the City

Corporation, the AQDMP should detail why they have not been adopted.

General measures and details for Demolition, Earthworks, Construction and Track-out

4.21 Preparing the site:

a. Plan site layout: Plans should be made to eliminate dusty works, where this is not

possible, dusty activity should be planned away from sensitive receptors, with

wind direction taken into consideration.

b. All sites should be sufficiently screened / wrapped in order to prevent offsite dust

deposition. Plans should be made for screening dust generating activity and for

water to be available for damping down.

c. Install green walls, screens or other green infrastructure to minimise the impact of

dust and pollution.

d. Provide showers and ensure a change of shoes and clothes are required before

going off-site to reduce transport of dust.

e. Where air quality monitoring is proposed, select appropriate locations and

commence baseline monitoring at least three months before phase begins.

Ensure the equipment is maintained and calibrated in accordance with the

manufacturer’s guidelines.

f. Plan for wheel washing facilities, where space allows.

4.22 Inspections, liaison and complaints:

a. Hold regular liaison meetings with other high risk construction sites within 500m of

the site boundary to ensure plans are coordinated and dust and particulate

matter emissions are minimised.

b. On/Off Site inspections: Carry out regular inspections to monitor compliance with

air quality and dust control procedures, including:

•

checking for spillages of cement and other powders (which should be

Ninth Edition January 2019

23

Pollution Control Team: 020 7606 3030

removed to prevent off-site deposition); and

•

checking buildings within 100m of site boundary (cleaning to be provided if

necessary).

c. Record inspection results, and make an inspection log available to the Pollution

Control Team when asked. The frequency of site inspections should be increased

(by those accountable for dust and air quality pollutant emission issues) when

activities with a high potential to produce dust and emissions are being carried

out, and during prolonged dry or windy conditions.

d. Incidents and Complaints: Record any exceptional incidents that cause dust

and air quality pollutant emissions, either on or off the site, and ensure the action

taken to resolve the situation is recorded in the log book. Record and respond to

all dust and air quality pollutant emissions complaints and make a complaint log

available to the Pollution Control Team when asked.

4.23 General site Management and Operations:

The operator should ensure fumes and/or dust does not escape from the site and

affect members of the public and the surrounding environment, the following

should be adhered to:

a. Use processes which do not generate fumes and/or dust and dusty material;

b. Ensure an adequate water supply and water pressure (using groundwater /

recycled water where possible) or a local exhaust ventilation is available on

the site for effective dust/particulate matter mitigation for:

o damping down dust generating activities and unsealed areas in dry

weather

o using mobile sprinkler systems and mobile bowsers

o using equipment fitted with fine mist sprays during dust generating

works

o collecting dusty material during dusty works;

c. Use enclosed (rubber) chutes, conveyors, covered skips, sheeting, bagging and

minimize drop heights to reduce the amount of dust produced on site;

d. Dusty works should be eliminated; where this is not possible, solid screens or

barriers of appropriate height should be erected around dusty activities and/or

the site boundary and action taken to prevent offsite deposition. The site

fencing, barriers and scaffolding should be kept clean using wet methods;

e. Ensure equipment is readily available on site to clean any dry spillages, and

clean up spillages as soon as reasonably practicable after the event using wet

cleaning methods;

f. The burning of materials on site is not permitted under any circumstances;

g. Careful consideration should be given to the location and temperature control

of tar and asphalt burners and the lid should remain closed when heating.

h. Avoid site runoff of water or mud;

i. Remove materials from site as soon as possible; and

j. Fabrication, cutting, grinding and sawing should ideally be undertaken off-site.

If the work must take place on site, the following techniques should be used. It

will be the Contractor’s responsibility to demonstrate that stated methodologies

are not available, and that every effort has been made to acquire them:

• Only use cutting, grinding or sawing equipment fitted or in conjunction with

suitable dust suppression techniques such as water sprays or local extraction;

• Areas used to undertake cutting and grinding should be screened; and

• Shears and guillotines or burners should be used in preference to disc cutters

on activities such as re-bar cutting and decking.

4.24 Vehicles, Machinery and sustainable travel

Vehicle choices and management can have a significant impact on air quality

within the City of London. For this reason, the following should be adhered to:

a.

E

nsure all on-road vehicles comply with the requirements of the London Low

Emission Zone and any subsequent traffic management policies to improve air

quality;

b. Ensure a consideration of items in sections 4.12-4.15 (NRMM compliance,

minimised generator use, appropriate concrete crusher use and no-idling

engines);

c. Wherever possible, vehicle movements should be minimised through full load

only delivery, considered logistics planning, liaison with other sites within close

proximity and the use of consolidation centres. To that end, a Construction

Logistics Plan should be produced to manage the sustainable delivery of goods

and materials. See TfL Guidance:

https://tfl.gov.uk/info-for/urban-planning-and-construction/transport-

assessment-guide/guidance-by-transport-type/freight

d. Implement a Travel Plan that supports and encourages sustainable travel to and

from site. See City Advice notes:

https://www.cityoflondon.gov.uk/services/transport-and-streets/Pages/

transport-strategy.aspx

e. Prevent the occurrence of smoke emissions or fumes from site plant or stored

fuel oils by ensuring plant is well maintained and measures are taken to ensure

they are not left idling when not in use;

f. Low sulphur diesel fuel should be used;

g. Wheel washers to be used on vehicles leaving the site (where site on space

allows);

h. Where there is a potential for dust releases, lorries and skips leaving the site to be

covered;

i. The generation of dust whilst loading or unloading materials must be controlled;

and

j. Where possible, vehicles visiting site should sign up and adhere to FORS

standards (or equivalent). Best practice has noted the use of an on-line booking

system which only allows compliant vehicles to attend site and this is

encouraged.

4.25 Waste management (see section 6 of this code).

a. Reuse and recycle waste to reduce dust from waste materials.

b. No bonfires or burning of waste materials.

4.26 Measures and details specific to Demolition

a. The use of ‘long arm’ demolition equipment will not generally be sanctioned in

the City, except where the work is within an enclosure or underground.

b. Soft strip inside buildings before demolition (retaining walls and windows in the

rest of the building where possible, to provide a screen against dust).

c. Ensure water suppression is used during demolition operations.

d. Explosive blasting is not permitted, use appropriate manual or mechanical

alternatives.

4.27 Measures and details specific to Earthworks

Due to site space restrictions, it is anticipated that material will not be stored on site

for extended periods within the City. Where it is, reference needs to be made to

contaminated land requirements in section 5. When material is stored or moved,

operations should be employed which minimise dust releases by stabilising

stockpiles and damping down when dry or moved.

4.28 Measures Specific to Construction

a. Scabbling should be done off site and will not generally be allowed in the City

due to the amount of dust generated.

b. Ensure sand and other aggregates are stored in bunded areas and are not

allowed to dry out, (unless this is required for a particular process, in which case

ensure that appropriate additional control measures are in place).

c. Ensure bulk cement and other fine powder materials are delivered in enclosed

tankers and stored in silos with suitable emission control systems to prevent

escape of material and overfilling during delivery.

d. For smaller supplies of fine powder materials, ensure bags are sealed after use

and used and stored appropriately to prevent dust.

e. Spraying of intumescent fire paint and cementations fibrous fire spray should not

be carried out in the city, due to air quality issues and difficulties in

encapsulating areas and will only be permitted when working areas can be fully

encapsulated and air monitoring carried out.

4.29 Measures Specific to Trackout

a. Ensure vehicles entering and leaving sites are securely covered to prevent

escape of materials during transport.

b. Install hard surfaced routes and areas to work, which are regularly damped

down with fixed or mobile sprinkler systems, pressure washers or water-assisted

dust sweepers. Areas should be regularly cleaned (avoiding dry sweeping of

large areas). Hard surfaced areas should be inspected for damage and

repaired where required.

c. Record all inspections of surfaces and routes to and from site and any

subsequent action in a site log book.

d. Ensure there is an adequate area of hard surfaced area between the wheel

wash facility and the site exit, where possible. Access gates should be ideally

located at least 10m from receptors.

e. Where reasonably practicable, implement a wheel washing system (with rumble

grids) to dislodge accumulated dust and mud prior to vehicles leaving the site.

f. Apply dust suppressants to locations where a large volume of vehicles enter and

exit the site (See GLA SPG for guidance with regard to dust suppressants).

5 Contaminated Land

Summary

Where the site is suspected of being affected by contamination, then appropriate

investigations and a subsequent remediation strategy and verification programme will be

the subject of planning conditions for any works that require planning approval.

Irrespective of whether or not the development is subject to such planning conditions, it is

the responsibility of the Contractor to ensure that appropriate investigations and risk

assessments have been carried out to characterise the ground conditions. It is similarly the

Contractors responsibility to ensure that appropriate action is taken and/or mitigation

measures put in place to ensure that:

• The works themselves do not pose any unacceptable risks to human health

(including construction workers, neighbours and the general public), controlled

waters or other eco systems.

• The development once completed does not pose any unacceptable risks to

human health (including subsequent construction/maintenance workers, future

occupants, neighbours and the general public), controlled waters and other eco

systems.

It is also the Contractor’s responsibility to ensure that:

• The City of London’s Pollution Control Team is notified of any ground contamination

that is found either during prior investigation or subsequently during development

• Any remediation which takes place is approved by the City of London’s Pollution

Control Team and is thoroughly documented in the form of a verification report.

Introduction

5.1 It is the duty of the Contractor to ensure that adequate work has been done to

investigate, evaluate and manage risks from contaminated land (whether it

originates on the site or not) to human health, controlled waters and other eco

systems.

5.2 General guidance is provided by the Environment Agency on its Land

Contamination: Technical Guidance website page which may be found at

https://www.gov.uk/government/collections/land-contamination-technical-

guidance. The Agency’s guiding principles of managing and reducing

contaminated land are explained in “GPLC2 - FAQ's, technical information,

detailed advice and references” which may be accessed at the above website.

The technical framework for the management of contaminated land is provided in

the Agency’s publication “Model Procedures for the Management of Land”, report

CLR11” which also may be accessed via the above website.

5.3 The technical framework is underpinned by a large number of Environment Agency

reports and tools, British Standards and other industry technical reports which give

specific guidance on the various aspects of investigation, evaluation and

mitigation of risks posed by contamination. Again the Environment Agency website

Ninth Edition January 2019

27

Pollution Control Team: 020 7606 3030

above provides a link to its own reports and tools. Cl:aire, CIRIA and the BRE are

other sources of industry reports, many of which are included in the references

section below.

5.4 The assessment of contaminated land in the UK is a risk based one. This means

that although contamination may exist in, on or under land, this may not in itself

present an unacceptable risk. A risk arises when there is a pollutant linkage i.e. a

receptor (such as humans) may be impacted by a source (such as hydrocarbon

contamination within the ground) via a pathway (such as inhalation of vapours).

That risk only becomes unacceptable once the magnitude of the risk exceeds a

set limit.

Phased Approach

5.5 The investigation and assessment of contaminated land requires the assessor to

identify potential sources of contamination, receptors and the potential pathways

that may connect them to establish potential pollutant linkages.

5.6 The investigations should be undertaken, in a phased manner, with the results of

each phase being used to decide whether or not there is a requirement to

proceed to the next phase. In some cases iterative investigation may be required.

At each step the Contractor should liaise with the Pollution Control Team before

proceeding to the next phase and where a phase indicates that no

unacceptable risks exist then must seek the Pollution Control Team’s approval

before omitting subsequent phases.

5.7 The methodology for site investigation appraisal and assessment is outlined in the

documents detailed above. The process of phased and iterative assessment is

summarised in CLR11, Figure 1.

5.8 The City of London is a densely populated area which has had a long history of

previous development including a range of potentially contaminating industrial

uses. As such the possibility of contamination must be assumed on all

development sites. The City Corporation will require, as a minimum, a Phase 1

Desk Study and Conceptual Site Model (CSM).

5.9 Where contamination is found (albeit on or off site) that poses unacceptable risk,

then a Remedial Options Appraisal shall be carried out to ensure that the selected

option meets the City’s targets for sustainable development as well as providing

the required mitigation measures.

5.10 Where remediation is required then a detailed Remediation Method Statement

shall be provided to the City Corporation for approval prior to commencement of

any remediation works. The Remediation Method Statement should include an

Environmental Monitoring Plan where it is identified that the remediation works

themselves may pose a potential risk to human health, controlled waters or other

eco systems.

5.11 On completion of the remediation, a verification report shall be provided. The

verification report should contain documentary evidence of the remediation

works carried out together with photographs and laboratory test results to support

decisions made on site.

Ninth Edition January 2019

Local Context

5.12 Geology and Groundwater

Due to the historical redevelopment of the City made ground is expected to

present (to varying thickness) across the area. Made ground or fill is by nature

highly variable in composition and may contain contaminated and/or putrescible

material. It can therefore be potential source of contamination and landfill gas.

5.13 The City of London is mapped by the British Geological Survey as being entirely

underlain by London Clay which is classified as Unproductive Strata.

5.14 Superficial deposits overlying the clay include Alluvium associated with the River

Thames along the southern boundary, and in linear deposits in the central and

western areas of the City. Hackney Gravel, Taplow Gravel and Lynch Hill Gravel

are mapped across the City and are classed as a Secondary Aquifer. Areas of

Langley Silt Member are mapped in the southern and eastern parts of the City.

5.15 Surface Water

The primary surface water feature within the City of London is the River Thames

located along the southern boundary of the City. The River Fleet and Walbrook

are both culverted, flowing south beneath the City and discharge into the

Thames.

5.16 Historical Uses

The City of London has a long history of industrial use dating back to the Roman

era. Historical maps of the City available from the 1870s detail a number of

industrial land uses which include (but are not limited to) warehouses and

wharves (predominantly along the River Thames boundary), railway land,

factories and works including printers, hatters, furriers and foundries; some historic

uses can be seen on the City’s interactive map.

5.17 Unexploded Ordnance

Approximately half of the City is mapped as having suffered WWII bomb

damage. Published copies of bomb damage maps are available on the City of

London web site as well as the website ‘Bomb Sight’ which records the positions of

bombs which landed across London.

5.18 A desk based UXO risk assessment should be undertaken, as a minimum, by an

appropriately qualified person for all works where ground is to be ‘broken’.

Mitigation measures may be required for intrusive works and or construction, with

appropriate contingency measures in place to deal with any suspect items.

Key Personnel

5.19 Due to the highly complex nature of site investigation, risk assessment and

remediation design; it is strongly recommended that the Contractor appoint a

specialist consultant at the earliest opportunity. In any case any contaminated

land report, risk assessment, options appraisal, remediation strategy or verification

report must be prepared and countersigned by a Competent Person.

5.20 A competent person is someone who has the appropriate qualifications and

experience to undertake the task in question. The Contractor may wish to use the

services of a SiLC (Specialist in Land Condition). A register of SiLCs may be found at

Ninth Edition January 2019

29

Pollution Control Team: 020 7606 3030

http://www.silc.org.uk/silc-register/ . Subject to discussion with the Pollution Control

Team, the City Corporation requires that all contaminated land reports are signed

off by a SQP (Suitably Qualified Person as defined under the National Quality Mark

Scheme).

5.21 The Pollution Control Team are responsible for approving contaminated land

reports and the Contractor is advised to contact the Team in the early stages of

planning.

Unexpected Contamination

5.22 If any undetected or unexpected contamination or ground gas is identified or

suspected during the course of the development works, the Contractor must stop

work, seek the advice of a competent person and undertake whatever further

specific investigations are required to characterise the contamination and develop

an appropriate remediation strategy. Where ground contamination is identified,

the Pollution Control Team must be notified. Where ground-water contamination is

suspected, then the Environment Agency and Pollution Control Team must be

contacted. All remedial work must be approved by the Pollution Control Team.

Waste Disposal

5.23 The City advises that all projects with an estimated construction cost exceeding

£300,000 excluding VAT have a Site Waste Management Plan and in any case all

waste must be disposed of in accordance with current legislation.

5.24 Appropriate soil tests must be carried out on all soils removed from waste to ensure

an accurate and appropriate waste classification.

5.25 It is a requirement of the waste legislation that hazardous and non-hazardous waste

be treated prior to disposal to change the characteristics of the waste and in so

doing either reduce the volume and/or hazardous nature of the waste and/or

facilitate handling and/or recovery. Additional hazardous and non-hazardous

waste must be separated.

5.26 Soils may be classified as non-hazardous or hazardous waste on the basis of its

chemical content.

5.27 Particular attention is drawn to the subject of asbestos in soils. Where the asbestos

content exceeds 0.1% by volume OR a competent person is able to detect

asbestos containing materials with the naked eye. The latter is likely to apply at

asbestos concentrations significantly lower than 0.1%

Re-use of Soils

5.28 The City of London promotes sustainable development and in this respect is

supportive of soil re-use where appropriate.

5.29 Where soils are to be re-used on the subject site (Site of Origin) or another site

(Receiver Site), then it is recommended that this is done in accordance with the

Cl:aire Code of Practice, otherwise the soils may be classified as waste, requiring

an EA permit or EA exemption before it may be reused.

Ninth Edition January 2019

30

Pollution Control Team: 020 7606 3030

5.30 It is noted that only natural soils (e.g. London Clay) may be moved and reused on

another site, whereas made ground or natural soils may be re-used on the site of

origin provided it meets key test criteria set out in the code.

5.31 Where soils are to be reused on site either in accordance with the Code or under

an EA exemption or permit then details must be forwarded to the Pollution Control

Team prior to re-use and all such re-use detailed in the final verification report for

the site.

General Site Activities and Controls

5.32 Notwithstanding the requirements to remediate or provide mitigation measures to

counter ground contamination, the Contractor must also ensure that all its activities

are undertaken in such manner as is required to prevent contamination of the

ground, ground-water and surface waters. This may include but is not restricted to:

• materials being stored in appropriate conditions to prevent

damage/contamination of storage areas;

• containers of hazardous or potentially contaminating materials being sited

away from drains and un-surfaced areas;

• containers of hazardous or potentially contaminating materials being fit for

purpose, regularly inspected and maintained;

• containers of hazardous or potentially contaminating materials should have

secondary containment (such as a bund) to contain any leaks or spills for

example, areas used for the storage of diesel fuel or chemicals

• All waste should be clearly labelled and segregated prior to offsite disposal to

prevent cross contamination and inappropriate disposal; and

• It is the Contractor’s responsibility to ensure that its principal Contractor and sub-

Contractors are made aware of the ground conditions and potential hazards

associated with those conditions.

Ninth Edition January 2019

Pollution Control Team: 020 7606 3030

6 Waste and Materials Handling and Storage

Summary

The Contractor must:

• ensure a Site Waste Management Plan is developed (if required);

• ensure waste is contained and disposed of in an appropriate manner and in

accordance with legislation and the Waste Management Hierarchy; and

• ensure methodologies are adopted that prevent environmental impacts by the

mishandling and storage of on-site materials and waste.

Waste Management

6.1 The City recommends any project costing over £300k is required to produce a Site

Waste Management Plan (SWMP) for new build, maintenance, and alteration or

installation/removal of services (such as sewerage or water).

6.2 The purpose of a SWMP is to ensure that building materials are managed efficiently,

waste is disposed of legally, and that material recycling, reuse and recovery is

maximised. As such, a SWMP sets out how all building materials, and resulting

wastes, are to be managed over the course of a project. For more information,

please consult the following websites: www.defra.gov.uk and

www.environment-

agency.gov.uk

6.3 Those sites with a budget of less than £300k must manage their waste according to

current legislation (see www.environment-agency.gov.uk

). Evidence of how waste

is disposed of, and efforts to reduce and recycle waste, must be maintained and

kept on site.

6.4 All site waste management must be planned and carried out in accordance with

the Waste Management Hierarchy, as demonstrated below:

6.5 All wastes must be removed from sites using a registered waste carrier and sent only

to disposal facilities authorised to receive it. Disposal must be in accordance with

relevant legislation.

Ninth Edition January 2019

32

Pollution Control Team: 020 7606 3030

6.6 All waste documentation - transfer notes, consignment notes, exemptions, waste

carrier and facility licences - must be held on site as required by legislation. Such

documentation must be maintained to be readily available for inspection at all

times.

Materials Handling and Storage

6.7 Materials should be stored in appropriate conditions to prevent

damage/contamination, of storage areas. Containers should be sited away from

drains and un-surfaced areas. Storage containers should be fit for purpose, regularly

inspected and maintained, and should all have secondary containment (such as a

bund) to contain any leaks or spills.

6.8 Fuels should be stored in compliance with current guidance and

recommendations.

6.9 Procedures and training should be in place for the safe delivery and handling of

materials, with regular site inspections carried out to ensure that once on site they

are stored safely and correctly.

Asbestos and other Hazardous Materials

6.10 All work on asbestos and other hazardous materials must comply with current

Legislation and HSE Approved Codes of Practice & Guidance.

6.11 Before any work is done or commissioned that is likely to disturb asbestos or other

hazardous material, the following must be worked out:

• The amount of hazardous material;

• Where it is and what condition it is in;

• Whether work is likely to disturb material; and,

• Whether and how the material needs to be safely protected or removed.

6.12 This can be achieved either by checking existing records (such as client’s survey,

asbestos plan or register) or commissioning a suitable survey before work starts. It is

good practice to include the need for such a survey in the initial project cost and

programme. For more information, please see the following and associated links:

7 Water

Summary

The Contractor must:

• ensure trade effluent is not discharged directly to surface or foul drains without

contacting the appropriate body;

• trade effluent consents are held on site;

• contact the City of London’s Drainage Services Group or Thames Water Utilities if

work is to be undertaken on sewer connections or drains running under the public

highway; and

• ensure the under-ground drainage systems are adequately designed and installed.

Discharge of Waste Water from Sites

7.1 Wastewater generated from site activities including water from dewatering

excavations, site run off slurry and bentonite are classified as trade effluent. These

should not be discharged direct to surface or foul drains without the consent of the

Environment Agency for controlled waters, and Thames Water for others.

7.2 The Contractor is responsible for obtaining necessary consents and ensuring

compliance with any conditions imposed on them. Copies of consents must be

held in a designated file kept on site. In cases of heavy water run-off, sumps must

be provided in order to deal with the issue.

Site Drainage, Temporary and Permanent Connections to Sewers

7.3 Contact must be made with the City of London Drainage Services Group (020 7332

1105) or Thames Water Utilities (0845 9200 800) before any work is undertaken on

connections to sewers or drains running under the public highway. The following

general requirements will have to be met:

• All redundant sewer communication pipe work must be sealed off at the

sewer. The remaining pipe work should be removed or filled with a suitable

weak concrete, cement grout or other suitable material. This is to prevent any

infestation by rodents and avoid the risk of future possible subsidence.

• All retained sewer communication pipes should be tested and a CCTV survey

carried out to ensure they are suitable for the new development and in good

condition.

• In order to prevent rodents or sewer gases reaching the site, temporary sewer

communication pipes must be provided with a ‘cascade’ cast iron

interceptor trap to British Standard specification.

7.4 It is strongly recommended that all under-ground drainage systems are installed

using pipes made of a robust material such as cast iron, and that inspection

chambers etc. are properly sealed with bolted down covers. This will prevent later

problems from damage by vibration or rodent access.

7.5 Wherever it is at all possible, the drainage system serving the proposed

development or refurbishment should gravitate to the sewer. This will eliminate the

need for pumping of foul drainage to the sewer and the associated problems

which regularly occur with this type of installation.

Ninth Edition January 2019

34

Pollution Control Team: 020 7606 3030

7.6 The sewage system within the City of London is vented to atmosphere via vents at

road surface level and any increase of discharge velocity resulting from pumped or

stored sewage being discharged to the sewer frequently results in complaints of

foul smells. These may well be treated as a statutory nuisance by the City of

London. The importance of designing a system which discharges to the sewer by

gravity wherever practicable cannot be overstated.

7.7 Note: Details of the City’s standard drainage connection requirements and the

related legislation are shown in Appendix E.

Ninth Edition January 2019

8 Sustainability and Preservation

Summary

The Contractor should:

• employ best practice and look for new innovative techniques in the priority areas

specified to ensure a more sustainable approach;

•

ensure the Department of Planning and Transportation has been contacted to

establish the status of the site

and what specific requirements are included in the

planning permission, listed building consent or conservation area consent;

• ascertain whether any trees on the site or immediate area are either protected or fall

within a Conservation Area prior to works starting; and

•

ensure an ecological survey has been undertaken by a qualified professional and

appropriate mitigation measures agreed with the City of London.

Climate Change and Sustainability

8.1 The City of London is working towards limiting the impact of the region and making

it more sustainable, demonstrated by (among other projects) the current

development of a Climate Change Strategy, and strongly encourages other parties

to do the same. Innovation and best practice in this area will therefore be highly

regarded in applications for the Environment Award through the CCS.

8.2 The Sustainable Development Commission has identified the following key priority

areas for action in the UK:

• sustainable consumption and production – greater efficiency in utilisation of

resources and minimisation of waste;

• natural resource protection; and,

• climate change and energy – both reducing energy consumption and

sourcing that energy from more sustainable sources.

8.3 Contractors should employ best practice and look for new innovative techniques in

each of these priority areas, thus ensuring the process of construction or

deconstruction is made more sustainable.

8.4 The impact of such techniques, or indeed highlighting of areas for improvement,

can be demonstrated by including life cycle analyses for materials/processes or

basic carbon footprinting in documentation submitted as part of the planning

process.

8.5 Examples of actions taken to increase the sustainability of the site could include:

• Use of the Mayor of London’s Green Procurement Code, in particular via the

procurement of FSC-approved/sustainable timber or equivalent, for example,

PEFC certification;

• Use of non-virgin aggregate;

• general good practice including ensuring that plant not in use is switched off

and that lighting is used only when necessary (such as through the use of

timers);

• Use of energy efficient bulbs or solar powered lighting;

• the use of existing feeds for power where possible to prevent the need for

generators, or the purchasing of energy/electricity from sustainable sources;

Ninth Edition January 2019

36

Pollution Control Team: 020 7606 3030

• Employment of energy efficient and, where possible, gas powered plant as

opposed to petrol/diesel;

• Efficient use of water as a resource, for example in cleaning systems or the

implementation of rainwater harvesting.

8.6 For more information regarding climate change and sustainability issues relevant to

a particular project or site, Contractors are encouraged to read the Climate

Change Adaptation Strategy available at:

https://www.cityoflondon.gov.uk/services/environment-and-

planning/sustainability/Documents/climate-change-adaptation-strategy-2010-

update.pdf

Archaeology and Built Heritage

8.7 Much of the City of London is designated as being of archaeological potential.

Archaeology is a material consideration of the planning process. Where

archaeological remains survive, the archaeological potential is considered as part

of the planning application. Where a development affects archaeology,

investigation and recording is required as a condition of the planning permission.

This may be to ensure the preservation in-situ of important archaeological remains

and to ensure that a record of the remains is made.

8.8 Some monuments and archaeological remains are scheduled ancient monuments

under Part I of the Ancient Monuments and Archaeological Areas Act 1979 and

scheduled monument consent is required to undertake any work that may affect a

scheduled monument. Scheduled Monument Consent is obtained from the

Department of Culture, Media and Sport and advice on this is available from

Historic England.

8.9 Some buildings and structures are included on the statutory list of buildings of

special architectural or historic interest. Listed building consent is needed to carry

out any work which may affect a building’s special architectural or historic interest.

8.10 The Contractor must ensure that the Department of the Built Environment has been

contacted to establish whether the site contains a listed building, scheduled

ancient monument or archaeological remains, and what specific requirements are

included in the planning permission, listed building consent or conservation area

consent. Conditions of a planning permission may include the requirement of a

programme of archaeological work and recording to be carried out as an

integrated part of the development, submitted to and approved by the

Department of the Built Environment before work commences (contactable via 020

7332 1710).

8.11 Advice and details of the need for Scheduled Monument Consent should be

obtained from Historic England (contactable via 020 7973 3000).

Trees and Wildlife

8.12 The local planning authority has specific powers under the Planning Acts to protect

trees and require the planting of a replacement tree in certain circumstances. The

Director of Open Spaces is also responsible for the maintenance and management

of street trees and trees within some of the city churchyards. The Contractor must

Ninth Edition January 2019

37

Pollution Control Team: 020 7606 3030

therefore ascertain whether any trees on the site or in the immediate vicinity of the

site are protected or maintained by the Corporation prior to starting work.

8.13 A tree may be protected in one of the following ways:

• By a Tree Preservation Order

• If it is located within a conservation area

• By means of conditions on planning permissions or other consents.

8.14 The City of London Tree Strategy Supplementary Planning Document (Part 1) and

the accompanying evidence and practice guidance (Part 2) sets out a co-

ordinated approach to the management of trees in the City of London. It provides

advice for anyone wishing to undertake work to existing trees or to plant new trees.

It can be found via the following link:

https://www.cityoflondon.gov.uk/services/environment-and-

planning/planning/heritage-and-design/Documents/Tree-Strat-Part-1-

Complete.pdf

8.15 Development schemes can have a major impact on existing trees including street

trees. It is essential therefore that the potential impact of the proposed works on

these trees is assessed at an early stage prior to the submission of any application.

This should include the demolition and construction process and future

maintenance of the building. Prior to undertaking any tree works or any works in the

vicinity of trees Contractors should consult the City Corporation Tree Strategy.

8.16 Prior to commencement of works on site, checks should be undertaken to confirm

whether there are any birds or bats that may be nesting/roosting within buildings or

vegetation. If present appropriate mitigation measures should be undertaken

following consultation with the City’s Department of Open Spaces 020 7332 3505.

Ninth Edition January 2019

9 Light Pollution

Summary

The Contractor must ensure:

• nearby residents and commercial occupiers are not adversely affected by light

pollution from the site;

• an energy efficient lighting approach is adopted; and

• lighting does not pose a hazard;

Light Pollution

9.1 Light pollution is a statutory nuisance and is defined as any form of artificial light

which shines outside the area it is required to illuminate. Unnecessary use of lights is

considered a waste of energy (see section 8.5). Any use of lighting should have

regard to these facts and should be designed to prevent any nuisance to residents

or road traffic and be used primarily for reasons of health and safety or security.

9.2 Site lighting should be located and aligned so as not to intrude into residential

properties, on sensitive areas, or constitute a road or rail hazard.

9.3 Site lighting outside of working hours should be designed to the minimum required

to ensure safety and security taking to prevent potential impacts on neighbours.

9.4 During the fit out stages of construction, it is a requirement that contractors will

utilise black out window coverings.

Ninth Edition January 2019

10 Problems on Site

Summary:

• If emergency work is required then the Contractor must contact City of London as

detailed;

• The Contractor must ensure that systems are in place to enable problems on site to

be identified and ensure that appropriate action is taken to mitigate the problem

and the appropriate parties are informed.

Emergency Work

10.1 The City of London appreciates that occasionally incidents arise whereby it is

impossible or impractical to comply with all the requirements within this Code. In

such an event, the Pollution Control Team should be contacted within the hours of

08:00 and 17:00. Outside of these hours The Out of Hours Team should be called on

020 7606 3030, leaving a name, mobile number, the nature of the emergency, and

the site address. Following this the Environmental Health Out of Hours Officer will

respond by calling the Contractor in order to ensure the presence of an

emergency and approve the method of work.

10.2 In the event of an environmental incident (e.g. a spillage), steps should be taken to

prevent pollution, for example through:

• Protection of drains by the use of drain covers or booms;

• Use of absorbent granules following an oil/chemical spill; and,

• Turning off equipment or other sources of noise or dust.

10.3 Once the situation has been rectified, full details about the incident and remedial

actions undertaken should be provided to the City of London and other relevant

authorities, and recorded in the site complaints/incidents logbook.

Pollution Emergencies

10.4 All sites should have a plan, equipment and training in place for dealing with

pollution emergencies. A summary of the plan should be visibly displayed around

site, and understood by all workers.

10.5 For more guidance on such planning, please see the Environment Agency

guidance ‘Pollution Prevention Pays – getting your site right’, downloadable at:

https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/4

85173/LIT_7481.pdf

Pest Control

10.6 The City of London has a statutory duty to take such steps as may be necessary to

keep the City free from rats and mice this includes enforcement of the Prevention

of Damage by Pests Act 1949.

10.7 When an occupier of any land, including a construction site becomes aware of an

infestation by rats or mice in large number he must notify Port Health and Public

Protection (020 7606 3030).

Ninth Edition January 2019

40

Pollution Control Team: 020 7606 3030

10.8 Appropriate measures must be taken to limit any insect, bird or rodent infestation.

Such measures are considered essential to limit future problems in completed

buildings - especially in the case of mice.

10.9 Pest control does not just include treatment by a pest control company; in fact this

is a last resort. Measures should be taken to:

• Prevent access to the site principally from exposed drainage;

• Reduce harbourage in order to ensure that rubbish or spoil is not left for long

enough allow rodents to establish themselves above ground;

• Limit potential food and water sources. It is particularly important to ensure that

waste food or empty cartons are not left in areas where they can encourage

rats and mice.

10.10 Many of the methods necessary to achieve adequate control should be part of

established construction/deconstruction methods. To report any problems with

infestations, or if you require any additional advice, contact the City of London on

the following number: 020 7606 3030.

11 Legislation and Documentation

Documentation

11.1 The Contractor should keep all appropriate documentation and records relevant to

the requirements of this Code in designated files held on or accessible from site (i.e.

electronic or on-line). They must be available at all times for inspection and review

by the City of London or other authorities and should include as a minimum:

• Scheme of Protective Works (as per section 2);

• liaison minutes, letters, photos and newsletters.

• noise, vibration and dust monitoring results (where applicable);

• waste management documentation (where applicable);

• inventory of non-road-mobile machinery and corresponding emission

standards, with the relevant plant registered on the NRMM website;

• Site hours variation sheets; and

• a complaints/incidents log with actions taken.

Section 60 and 61 Notices

11.2 The Control of Pollution Act 1974 Part III restricts and limits noise and vibration from a

construction site. If complaints are received, where it is considered necessary, the

Department of Markets and Consumer Protection will serve a Section 60 notice on

the Contractor for the control of noise and vibration at the site. This notice can:

• Specify the plant or machinery that is or is not to be used;

• specify the hours during which work can be carried out; and/or,

• specify the levels of noise and vibration that can be emitted from the site.

11.3 The Contractor can apply in advance for a consent in the form of a Section 61

notice regarding the methods and conditions by which they are intending to

undertake the works and control nuisance.

11.4 The City does not advise the use of Section 61 consents but it does support a system

of prior agreement on similar lines, as this allows a much more flexible approach of

greater benefit to the Contractor. Section 60 notices will be served where they are

considered necessary. Contraventions of either Section 60 or 61 may well result in

legal proceedings, leading to further costs and delays for the Contractor.

Considerate Contractor Scheme Information

1. The Considerate Contractor Scheme (CCS) comprises:

 a Code of Good Practice, covering care, cleanliness, consideration and

cooperation;

 regular inspections by the City's Considerate Contractor Surveillance Officers;

 an annual judging and awards ceremony; and

• a telephone hotline enabling the general public to comment on the Scheme,

sites and on participating Contractors. (020 7332 1104 / email

ccs@cityoflondon.gov.uk)

Note: general compliance with this Code of Practice is also a requirement of the

scheme and sites will be judged and scored in this context.

2. The CCS is a co-operative initiative open to all Contractors undertaking building

and civil engineering work in the City of London. There is no membership fee, but

on joining the Scheme, members agree to abide by the Code of Good Practice.

It is by following this voluntary Code that the general standards of works are raised

and the condition and safety of City streets and pavements improved for the

benefit of everyone living, working or just travelling through the Square Mile.

Membership of the CCS is actively encouraged for all construction and

deconstruction works in the City.

Additional information and a copy of the code of practice can be obtained from

The Department of the Built Environment Highways Division representative on 020

7332 1104 or by email to [email protected].uk

3. An Environment Award is available as a separate achievement in the Considerate

Contractor Scheme to recognise and encourage best practice and innovation in

the sustainability of City construction and deconstruction. For details email

APPENDIX E

The City of London Sewers Act 1848

City of London Standard Requirements

1. All communicating drains to the sewer outfall must be provided with a cast iron

intercepting/disconnecting trap which has a cascade, with access to the crown of

the trap and have rodding access through to the sewer as BSS figure 26 or equivalent

(for rodent control measures).

2. The communication pipework should be laid in straight lines in the vertical and the

horizontal alignments and with no other pipe connections. (e g at a self-cleansing

velocity and in a straight line from interceptor to the sewer).

3. The interceptor should be located inside the property boundary and adjacent to the

buildings curtilage.

4. There should be provision to provide ventilation to the low invert level of a drainage

system this should normally be at the intercepting trap. It may be difficult to evaluate

air movement precisely and therefore as guidance you should allow for the vent pipe

to be half diameter at the size of the intercepting trap. This vent should be discharged

to a safe outlet at roof level atmosphere.

NOTES

a) The sewage system within the City historically vents to atmosphere via low level vents

and any increases of discharge velocity (e.g. pumped drainage) of building effluent

to the sewers results in the incidences of smells being reported. As justified smell

complaints are treated as a statutory nuisance by this Department. It is STRONGLY

RECOMMENDED where practicable and safe to do so all drainage should discharge

via gravity.

b) In the view of the City there are rodents present within the sewers and special rodent

control is therefore required, historically the measures the Cityaccepts is both by

means of an interceptor trap and a sealed drainage system. You should discuss this

matter with your Building Control body/Advisor.

c) There is a requirement under Section 62 of the Building Act 1984 for any person who

carries out works which result in any part of a drain becoming permanently disused

that they shall seal the drain at such points as the City may direct. You should

therefore make arrangements to seal off any redundant communication drains

connecting to the Thames Water Utilities (TWU) sewer at the point of communication

with the local sewer and at the buildings curtilage.

d) The City now requires in some instances the introduction of sewer vent pipes. Via the

Planning process. The information required for this approval is shown below:

• A long sectional detail is required for each connection. Copy of standard City

detail is shown.

• Minimum size of sewer vent to be 150mm.

• Confirmation of materials proposed, pipework must be rodent proof, i.e. light weight

iron or similar.

• Basement, ground floor and roof level layout plans are required, showing sewer

vent pipework.

• Locations of the sewer vent pipework, in building, to be shown, i.e. in a duct or riser.

• Schematic drawing of all soil and waste pipework, clearly showing sewer vent with

route of the sewer vent highlighted so it is easy to identify.

Pollution Control Team: 020 7606 3030

Any failure in respect of these requirements may result in: -

1. Charging of costs and expenses involved in attending site and auditing works.

2. Copies of documents concerning any default being placed on our Land Charges

Register and disclosed to all subsequent enquiries

3. Charging for remedial works done in default and costs recovered from responsible

person(s) which may be substantial in terms of cost and delays to the project.

You are advised to submit proposals in writing concerning these matters to the above

address

APPENDIX F

Traffic Management Requirements

General

The Contractor will be required to use designated traffic routes. These must be agreed

during the site operations planning stage with the Department of Markets and Consumer

Protection Highways Management Group (020 7332 3993).

If necessary, proposed routes will also be discussed with The City Police (020 7601 2222),

Transport for London (020 7474 4770), Port Health and Public Protection (020 7606 3030) &

The Metropolitan Police. (020 7230 1212).

Whenever possible vehicles must enter and exit the site in a forward direction, any

exceptions to this rule must have prior consent from the Department of Markets and

Consumer Protection Highways Division (020 7332 3578).

A competent banksman should be provided to assist your drivers accessing & leaving

sites where there are busy streets etc., thereby ensuring pedestrian safety & minimal

disturbance to other traffic.

Deliveries to the site should be properly co-ordinated. Parking in local streets whilst

waiting for access to the site is not permitted. A ‘parking dispensation’ will be required

for vehicles unloading or loading in the street. (Contact the Traffic Management Office

on 020 7332 3553 to arrange this)

The Contractor will be held responsible for any damage caused to the highway by site

activities and will be required to carry out the temporary or permanent reinstatement of

roads, kerbs, footpaths & street furniture to the satisfaction of the City.

The City encourages use of systems where vehicles serving sites regularly are identified by

prominently displayed notices.

Contractors must not allow mud or other spoil from sites onto the highway adjacent to

the site. Wheel washing plant or other means of cleaning wheels must be used before

vehicles leave unpaved sites.

Arranging road closures in connection with crane & other heavy lifting equipment

deliveries.

The correct procedure involves firstly telephoning the Pollution Control Team to agree the

hours of operation and noise implications of your outline proposals on 020 7606 3030.

The ‘mobile crane environmental health authorisation & structures form’ – ‘Appendix I’

should then be completed and e-mailed to the Pollution Control Team via the following

e-mail address for approval: publicprotection@cityoflondon.gov.uk

Once received, the completed form will be checked, any necessary amendments

agreed with the applicant and returned to the applicant signed by the authorising

officer.

Ninth Edition January 2019

xi

Pollution Control Team: 020 7606 3030

Formal application for any crane operation and / or road closure must then be made in

person to the Department of Built Environment’s Traffic Management Office.

Applications will only be considered by appointment, and applicants must have details

of the proposed date, time and nature of the operation at this time. Also, a completed

‘Appendix I’ signed by the authorising officer must be presented, together with the

appropriate payment. For details of current charges or to make an appointment,

telephone 020 7332 3553.

Important Note- Underground ‘Structures’

The part of Appendix I relating to ‘structures authorisation’ must also be signed by the

crane company’s representative before it is presented to The Traffic Management office.

It is the crane operators responsibility to check whether there are any underground

‘structures’ such as subways, car parks, vaults or railway tunnels under, or adjacent to the

part of the highway where the crane is to be sited.

Operators must contact the City’s Structures officer on 020 7332 1544 to discuss the

operation and, if required, the owners of any private underground structures such as

London Underground Ltd. (020 7222 1234)

Abnormal Loads

Prior permission for any abnormal loads (as specified in legislation enforced by the City of

London & Metropolitan Police forces) is required from The City of London Police’s traffic

planning section (020 7601 2143) & The Metropolitan Police’s abnormal loads section (020

8246 0931). Generally, such deliveries have to take place on weekdays after 19.00 hours

or at weekends and may also require prior agreement from ‘Transport for London’.

Contact 020 7474 4770.

Standard for Construction Logistics – Managing Work Related Road Risk

In addition to the particular requirements above, the City expect all Contractors to

observe the Standard for Construction Logistics – Managing Work Related Road Risk,

especially as all journeys have to pass along routes administered by Transport for London.

It is recommended that all Developers/Project Managers include adherence to the

Standard as a contractual obligation for all of their Contractors.

Fleet Operator Recognition Scheme

The City of London has a fleet of around 150 vehicles, and has a Gold accreditation

FORS assessment. It is expected that all fleet operators within the City will be a member

of the scheme, with at least a Bronze accreditation. Whilst it is recognised that most

construction sites will be serviced by a variety of construction suppliers, the City of

London will actively encourage all developers and project managers to insist that ALL

vehicles visiting their sites are registered with FORS. MACE and Berkeley Group have now

made this a contractual obligation

There will be some circumstances where the impact of the works will be very small, for

example where planning permission was required because of a buildings listed status

and the works are very minor. In such cases the sites will be considered “out of category”

and will not be required to pay any fee. Such consideration will be on a case by case

basis and such exemptions are expected to be few.
