1 Introduction

1.1 General

1.1.1 All works covered in this document are to be managed and performed tothe culture within the Thames Tideway Tunnel projectsvision of ZeroIncidents, Zero Harm, Zero Compromise.

1.1.2 This Code of Construction Practice(CoCP) is submitted as part of theapplication for development consentapplication (the application) for theThames Tideway Tunnel project (the project). The development consentorder (DCO) is an order under the Planning Act 2008 approving adevelopment; it is the statutory instrument defining the terms under whichdevelopment consent would be granted.

1.1.3 The principles and requirements within this CoCPrelate to themanagement of construction impacts and are to be read in conjunctionwith safety legislation and the employers Health, safety, security andenvironment standard( the HSSE Standardi) for contractors.

1.1.4 The CoCPhas been carefully developed to reduce and minimisetheeffectsof the projectduring construction. It aims to provide appropriateand clear means of monitoring and enforcing compliance with a widerange of good practice measures and sets out a series of measures andstandards of work, which will be applied by the contractor throughout theconstruction period to:a. provide effective planning, management and control duringconstruction to manage and mitigatepotential impacts on people,

businesses and the natural and historic environment

b. provide the mechanisms to engage with the local community and itsrepresentatives throughout the construction period.

1.1.41.1.5 The employer is the party responsible for the delivery of the project, (ie,the party in whom the powers of the DCOare vested or transferred,todeliver the project). The employeris responsible for all of the works, whichincludes overseeing the contractor. The employerwill have a projectmanagement organisation in place,which will be suitably skilled and

resourced to undertake this duty.1.1.51.1.6 The term construction in the CoCPincludes all physical works undertaken

to implement the project: utility diversions, site preparation, demolition,material delivery, removal of excavated material removal,andwasteremoval, tunnelling and shaft construction, interception of existingcombined sewer overflows (CSOs), installation of equipment, landscaping,commissioning, and all related engineering and construction activities asdefined in Schedule 1 of to theDCO).

i

This will be produced for the project to achieve outstanding arrangements for health, safety, security andenvironment.

1.1.61.1.7As the project extends across 14 local authoritiesLondon boroughs, theCoCPestablishes the basis for a consistent approach to the managementof construction impacts across local authority boundaries,and with arange of key stakeholders. Any construction codes or guidancedocuments relating to construction that have been produced by the local

authorities were considered during the preparation of this document.1.1.71.1.8 The CoCPcomprises of two parts:

a. Part A: General requirements. These measures are applicableproject wide.

b. Part B: Site-specific requirements. These are minimum site-specificmeasures,identifying or deviations from the general requirementsindicated in Part Athat will be implemented by the contractor.

1.1.81.1.9 The CoCPsets out a series of measures to be applied throughoutconstruction to mitigate the potential impact of site activities. Significant

effects from construction insofar as they may affect onthe natural andhuman environment, amenity and safety of local residents, road users andtraffic flow, businesses and the public,. Anysignificant effects fromconstruction will be limited in the vicinity of the works by implementation ofthe code.

1.1.91.1.10 The CoCPsupports the planning and delivery of the project in asustainable, efficient and cost-effective manner to meet the objectives ofthe Sustainability Statement,. It also andpromotes co-operation with otherprojects in the vicinity, as far as practicable, in order to reduce combinedimpacts.

1.1.101.1.11 The contractor will adhere to a works contract, which thatwill referenceUK water industry standards, Thames Water requirements for capitaldelivery standards and Sewers for Adoption,as appropriate.

1.1.111.1.12 Requirements within the DCOstate that the project shall will be carriedout in accordance with both Parts A and Part B of theCoCPunless agreedotherwise with therelevantlocal authority. Further specific measures foreach site may be made through amendments to the CoCP Part Bs, inagreement with the relevant local authority and in consultation with therelevant key stakeholders including Transport for London (TfL), theEnvironment Agency (EA), the Port of London Authority (PLA), the Historic

Buildings and Monuments Commission for England (HBMCE, formerlyreferred to as English Heritage), and the Marine ManagementOrganisation(MMO).

1.1.121.1.13 When an agreement or approval is sought from the relevant localauthority and not obtained (or obtained on terms that are not satisfactoryto the employer), then it will be open to the employer to appeal to theSecretary of State under the appeal mechanism set out in the DCO(Sschedule 17, para.4). Applications made further to rRequirements areto be regulated by virtue of Schedule 17,paras.1 to3); and any otherapplications or requests made under the DCO are to be regulated by DCOarticle 53(2).

1.1.131.1.14 Within this document, the terms reasonable and practicable meansare used. Any decision of what is reasonable or practicable will be madeby the employer in accordance with the terms of the works contracts.

1.1.15 Within this document,the term consultation is used to describe theprocess of sharing and discussing draft information with stakeholders. ThecConsultation will take have due regard to any comments received,wherever practicable. If no comments are returned within the consultationperiod,this will be deemed as to mean tacit acceptance. The length ofconsultation periodsof consultation may vary.

1.1.16 Throughout the CoCPa number of plans, procedures and reports arereferenced. For the purposesof this document,the following terms aredefined as:

a. Approved: When a plan, procedure, report or other item is to beapproved, this means that it needs to be signed-off by a regulatorybody that itasmeetsingthe legislative and project requirements by theapprovinga regulatory body and/or by the employer as specified withinthis document

b. Agreed: When a plan, procedure, report or other item is to be agreed,this means that the relevant 3rdthirdparty is informed and/or satisfiedthat the submission meets the intended and/or specifiedrequirements;.Ttypically this is a non-regulatory authority, eg,.utility orland owner

a.c.Accepted: When a plan, procedure, report or other item is accepted, itmeans that it is provided for information and meets the specified

requirements with respect to content. Typically this is for works underthe contract between the employerand the contractor,and is part ofthe employers supervision of the project.supervision by the employer

1.1.17 Where the CoCPstates approved or agreed by the employer,thistheplan, procedure, report or other itemwill be implemented via the NEC3contract between the employerand the Ccontractor and is administered bythe acceptance procedures of the Project Manager, as defined within thecontract.

1.1.141.1.18 The contractor will comply with the terms of the DCO,including thisCoCPand any other relevant legislation referenced in this document or

2.4 Enforcement

2.4.1 Compliance with the provisions of this CoCPwill be enforceable by virtueof a number of mechanisms.

2.4.1 A breach of the Code of Construction PracticeCoCPwould effectively be abreach of a DCOrRequirement (project-wide Requirement PW6 requirescompliance with the CoCPPart Aand Bs).

2.4.2 Project-wide requirement PW4 requires the details of the body or bodiesresponsible for undertaking each of the works at a site to shallbe providedto the local planning authority. Both the contractor and the employer wouldbe potentially be open to enforcement action under Section 161 of thePlanning Act 2008 and, in theevent offailure to comply with the terms of aSection 61 notice, under the Control of Pollution Act1974 ( the CoPA).

2.4.22.4.3 Compliance with the provisions of this CoCPwill be enforceable by virtue

of a number of mechanisms.2.4.3 Compliance will be enforceable against the employer by virtue of project

wide requirement PW6, which requires compliance with the CoCPPart A(as well as those site specific requirements addressing the CoCPPart Bfor that site).

2.4.4 The employer will be able to enforce the contractors compliance throughthe construction contracts. Compliance will be enforceable by theemployer against the contractor through the construction contracts whichbetween the employer and the contractor will enter into.

2.4.5 In addition, tThe CoCPobliges the contractor to seek and obtain consent

pursuant to sSection 61 of the Control of Pollution Act 1974 (CoPA)for theway in which certain works are to be carried out., and l Local authoritieswill have the power to serve a notice under Section 60 of the CoPA in theevent that the terms of the consent are not adhered to. Contravention ofthe requirements of such a notice without a reasonable excuse is anoffence.

2.4.6 Similarly, the CoCPidentifies certain other consents, licences and permitsthat will bearerequired by under other legislation, and thesewhichprovidea further means of ensuring that the works are carried out in the way thatisasdescribed in the CoCP.

2.4.7 Each contractors project manager will be responsible for ensuring that thework is planned and managed to be undertaken in accordance with allrequirements of theisCoCP. Each contractors project manager willrequire their its environment manager to undertake a programme ofmonitoring and auditing to confirm compliance.

2.4.8 Site inspections and audits will be carried out by the employer todetermine the ensurecompliance with the CoCP. Regulating authoritiesmay also attend site to confirm ensure compliance with relevant permitsand consents.

2.4.9 The construction contract will require the contractor to ensure that all sub-contractors and suppliers meet the requirements of the CoCP.

The employerandcontractor will take reasonable steps to engage with nearby residents,including those who may be detrimentally affected by constructionimpacts. The contractor employerwill ensure thatthe contractor informsoccupiers of nearby properties are informed in advance of works takingplace, including the type and duration of the activity. In the case of workrequired in response to an emergency, the local authority and localresidents will be advised as soon as reasonably practicable that short

notice work is taking place. This will comply with the HSSEcommunication procedure (refer to HSSE Standard, Section8.1).

3.1.2 The contractor will develop, in conjunction with the employer, acommunity liaison planwith, and for approval by the employer, which willinclude the following:

a. Monitoring of contractor and subcontractor compliance withundertakings and performance against relevant commitments, localagreements and specific community requirements throughout theproject. (These will be defined in the Sustainability StrategyStratementand in the project environmental management plan).

b. Maintenance of regular communication with the community, otherstakeholders and affected parties to ensure they are all kept informedof the scope of works being undertaken, and the progress of the worksand programme. The contractor will be required to produceinformation sheets of the works to be carried out, detailing expecteddisruptions and the measures being taken to minimise or mitigateadverse impacts of these works, at least two weeks prior toconstruction activity taking place. A liaison plan will be issued inadvance to the employer and appropriate local authorities, detailingthe information to be supplied, for acceptance approval by the

employer. The plan will include details and a map of properties to benotified directly with information sheets.

c. For tunnel boring, a website will be established (by the employer) thatwill provide information on the forecast and actual passage of thetunnel boring machines (TBMs). The contractor will be required todistribute leaflets along the route of the tunnel drives, giving notice ofthe forecast passage of the TBMs as the work progresses.

d. Liaison with appropriate local community projects, employment andeducational initiatives.

e. Provision of a point of contact for a small claims procedure, relating to

claims of physical damage to property, or minor injuries. The

contractor will assist in enabling any claims to be progressed promptlyin co-ordination with the employer and insurer.

f. Co-ordination of preconstruction defect surveys in properties whichhave been identified. Liaison, in conjunction with the employer, withthe building surveyor employed to carry out the surveys, and also tomaintain a dialogue with the relevant property owners throughout theduration of the works.

3.1.3 Appropriate meetings will be held with residents (or their representatives),businesses and other local occupiers to keep them informed about theworks, and to provide a forum for them to express their views. Therelevant local authority will be invited to participate.

3.1.4 The employer will maintain a telephone helpline service during theprogramme construction period to handle enquiries and concerns from thegeneral public. It will also act as a first point of contact for information inthe case of any emergency. All calls will be logged, together with a recordof the responses and action taken. Appropriate contacts and responsetimes will be the subject of a detailed procedure to be agreed prior to thecommencement of construction. Potentially affected occupiers will benotified of the helpline number and it will be widely advertised.

3.1.5 A confidential reporting line will be operated by the employer which links tothe HSSE and Project Incident Plan.

3.1.6 A complaints register will be maintained by the employeror the contractor,and a copy will be provided to the relevant local authority each month (orsuch other interval as is agreed with the local authority). The contractor

will notify the employer of complaints when they are received, along withthe event and any on-going actions.

3.1.7 Onsite communications, such as daily shift and activity briefings will beused to advise the site workforce of health, safety, environmental, andcommunity matters. This will include information obtained from communityliaison on items such as noise generation and access issues, together withconstraints detailed in the contracts (eg, working hours). Thiscommunication will be given to all relevant workforce, including newstarters and sub-contractors, before they commence work. Furtherinformation can be found in the health and safety documentation. Toolboxtalks will be used as a means to disseminate information to the workforce

on a routine basis.

3.1.8 The employer will establish a framework of coordination andcommunication meetings with key stakeholders. The contractor will attendmeetings as required and arrange other meetings where required. Anyother meetings identified by the contractor will be notified to the employer.Meetings will include a regular traffic/transport liaison meeting with TfL,EA, PLA, and Natural England where relevant, and the associatedborough to consider all sites in that borough.

3.1.9 The employer will also establish project-wide coordination meetings withlocal authorities, TfL, the EA, PLA, and Natural England at critical phases

throughout the works for the scheme as a whole.

4.1 Construction process

4.1.1 The construction of the project will extend across central London andrequire a number of major construction sites as well as smallerconstruction sites.

4.2 Working hours

General

4.2.1 The activities at the worksites are varied and include construction of majorshafts, tunnels and other activities that will be constructed over extendedperiods of time and will include periods of working on a continuous 24-

hour, seven days a week basis.

4.2.2 There will be variations in the hours of working between different siteswhich will be dependent on the ability to mitigate the potential effects ofsite working. The specific land uses and potential receptors surroundingthe sites will also influence the working hours. The working hours by typeof site are described in paras.4.2.11 to4.2.13.

4.2.3 Working hours are identified in the CoCP Part B for each site.Requirements within the DCOprovide that the project will be carried out inaccordance with both Part AandPart Bsof theCoCP,unless agreedotherwise with the local authority. The contractor may apply pursuant toSection 61 of the Control of Pollution Act 1974 to vary these working hourswhich will have been fixed and approved by virtue of the CoCPPart B inthe light of the contractorsdetailed working methods. Further Section 61application guidance is contained in Appendix A.

4.2.4 The Section 61 application process will include submitting noise andvibration predictions and associated mitigation, as appropriate and agreedwith the local authority. This is detailed in Section 6 of this document.Whenimplementing best practicable means(as defined in the CoPA)forthe control of noise and vibration, as defined in CoPAmeasureswill beconsistent with the recommendations of BS5228 (2009): Code of practice

for noise and vibration control on construction and open sites.

4.2.5 This section provides details of the working hour classifications, as well asthe flexibility to enable detailed agreement of the works between thecontractors and local authorities through Section 61 consents,dispensations or variations to ensure that the construction activities aremitigated in order to protect local sensitive receptors.

Classification of working hours

4.2.6 The working hours at the worksites will depend on the constructionactivities. The following table classifies the types of working hours that will

be applied.

Plus maintenance periods1pm 13:00 to 5pm 17:00Saturdays

10am 10:00 to 4pm 16:00Sundays

These hours consist of:

a. standard working hours

b. mobilisation period

c. maintenance period.

These are the standard hours that will apply tothe majority of worksites and constructionactivities.

These hours are the same as those that aredefined by most local authorities within theirindividual boroughs.

Mobilisation period: Mobilisation activities will

comprise the following: arrival and departure ofworkforce and staff at site and movement to andfrom place of work (if parked up, engines to beturned off, staff to remain considerate ofneighbours, no loud music or raised voices);general refuelling (from jerry cans only, use offuel tractors/bowsers to be limited to standardworking hours); site inspections and safetychecks; site meetings (briefings and quietinspections/walkovers); site clean-up (sitehousekeeping that does not require the use ofplant); site maintenance; and low keymaintenance and safety checking of plant andmachinery (provided this does not require orcause hammering or banging etc).

Mobilisation does not include lorry movementsinto and out of the sites.

Maintenance period: The activities allowed inthis period are limited to those that do not causesignificant noise or vibration. Maintenanceactivities will comprise general mechanical

maintenance to construction machinery andplant such as cranes, excavators, compressors,grouting equipment and dewatering pumps.Only essential maintenance works will beundertaken on Sundays.

Extended working hours

6pm 18:00 to 10pm 22:00weekdays

1pm 13:00 to 5pm17:00Saturdays

These are intermittent and are required to covercertain construction activities that will not becompleted during standard working hours.

These activities comprise works for majorconcrete pours and piling/diaphragm wall works.

The number of work activities that require theseextended working hours are limited, and are not


23/118



17


necessarily on consecutive days.

The detail of the duration and frequency of theintermittent requirement for extended working

hours will be included within the Section 61application.

Where these works are not defined within theCoCP Part B, they will be agreed with the localauthority through a Section 61 consent,dispensation, or variation, and notified torelevant stakeholders (eg, TfL).

Continuous working hours

12am 00:00 to 0012:00pmMonday to Sunday

For the tunnel construction activities, theunderground work andessentialsurfacesupport activities will be undertaken on a

continuous 24-hour, seven days a week basis.Underground work includes maintenance ofunderground machinery and plant.

Essential Surface surface support activitiescomprise works required to support tunnellingincluding excavated material processing andhandling, shaft lifting operations, tunnel liningsupply, grout and concrete batching plantoperation, barge loading and movements.

Out of hours/possession working

It is beneficial to undertake a number ofactivities outside of the standard working hours.These are required:

a. for utilisation of periods of low traffic flowsfor items such as abnormal loads/construction plant delivery; works within thehighway or footpaths; works affectingoperational railways

b. for utilisation of periods with low demand orflows for utility diversions and works on theexisting sewer system

c. to ensure minimum disruption to thirdparties who may have on-going operationsduring the day.

This will be agreed with the local authoritythrough a Section 61 consent, dispensation orvariation, and in consultation with relevantstakeholders.

Tidal working Certain works are located in the foreshore andthe construction activities will be required to beundertaken at high or low tides. Any tidal

working outside of standard working hours willbe agreed with the local authority through a


24/118



18


Section 61 consent, dispensation or variation,and notified to relevant stakeholders.

River and rail transport hours

As continuous working hours12am 00:00 to 12pm00:00Monday to Sunday

Main tunnel construction sites have the

opportunity for excavated material to beremoved by barge or train. At these sites bargeand/or train loading and transfer will be on acontinuous 24-hour, seven days a week basis.

The movement of barges from constructionsites is linked to the state of the tide and will beundertaken when the tide suits bargemovement. Small CSO sites using the river willbe dealt with on a site-by-site basis in Part B ofthe CoCP.

Short notice working On a major project such as this, there is thepotential for works that need to be completed orundertaken to secure and make safeconstruction operations that will be outside thestandard working hours.

At the commencement of the works, theprocess for notifying and coordinating theseworks with the local authorities and relevantstakeholders will be agreed with the localauthority through a Section 61 consent,dispensation or variation, and notified to

relevant stakeholders.

4.2.7 Key support activities are required for safeguarding the works and arerequired to be in operation and maintained on a continuous 24-hour,seven days a week basis. This includes items such as site security,pumps, ventilation fans, cranes and compressors. Such equipment will beshielded to provide noise attenuation, as appropriate (refer to Section6).

4.2.8 Suitably qualified staff will be required to undertake monitoring and collectdata and samples outside the standard hours, both within the worksite andin the surrounding areas.

Deliveries and lorry movements

4.2.9 Deliveries will be arranged to limit impacts on the road system. Deliveriesand all vehicle movements will be restricted to standard working hours, orextended hours, unless agreed with the local authority through a Section61 consent, dispensation or variation, or site specific requirements in theCoCPPart B. Abnormal and special loads (as defined in the RoadVehicles (Authorisation of Special Types) (General) Order 2003 (S.I.2003/1998) may be delivered outside standard working hours, subject tothe requirements of the highways authority and the police. Any furtherrequirements for a specific site will be included in the CoCP Part B. Lorry

movements during extended working hours must relate to the activity thatrequires the extension.
