Code of Construction Part B 1

1 Introduction

1.1.1 All works described in this document are to be managed and performed tomeet the health and safety vision of Zero Incidents, Zero Harm, Zero

Compromisefor the Thames Tideway Tunnel project (the project).

1.1.2 The Code of Construction Practice (CoCP)comprises two parts:

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

b. Part B: Site-specific requirements. These are site-specific measureswhere deviations from the general requirements are indicated inPart A.

1.1.3 This document forms the CoCPPart B for the project works at theChambers Wharf site and sets out detailed site-specific measures

including working hours, site set-up and servicing arrangements, takinginto account environmental matters and consultations with the LondonBorough of Southwark and other stakeholders.

1.1.4 For ease of reference, this document sets out site-specific issues anddeviations from Part A; therefore where no site-specific measures arespecified, reference should be made to Part A.

1.1.5 A plan of the location of the site is shown inFigure 1.1 overleaf.

Site layout The contractor shall use best endeavours toposition required offices and storage containers or

structures in the site layout to serve as noisebarriers, having regard to effects on daylight andsunlight. Specifically, the contractor shall considerpositioning three-storey offices or equivalent on thesouthwestern corner by Chambers Street or thewestern boundary of the site to act as noise barriersas this area of the site is closest to St MichaelsRoman Catholic School and Axis Court.

The site layout, hoarding and noise barriers in thewest of the site shall be designed (where practical)to minimise potential adverse sunlight/daylight

impacts on the lower floors of Axis Court.

The contractor shall refer to the Building ResearchEstablishment Guidance Site Layout Planning forDaylight and Sunlight: A Guide to Good Practiceand carry out an assessment of the impact of lossof sunlight/daylight at properties adjacent to the sitewhen developing the site layout.

The contractor shall ensure that noise-generatingactivities are located as far away from sensitivereceptors as is practicable.

The contractor shall consult the local authorityduring the development of the site layout.

Site security/hoardingrequirements

The hoarding shall be planted and incorporatesuitable art work on public-facing sections, asdefined in CoCPPart A para. 4.3.4a and c.

The hoarding height shall be 3.6m around this site.A 5m high hoarding/noise barrier shall be erectedon the eastern edge of the site.

on the cofferdam shall be constructed withtransparent acrylic sheet with a minimum thicknessof 6mm and to meet noise attenuationrequirements. Up to 1m from ground level, thebarrier shall be plywood and the section above shallbe transparent to minimise visual impacts.

3.6m high acrylic sheet shall be considered on theriver walls to reduce the noise effects at 8-14Fountain Green Square. The location of the acrylicsheet falls outside the limits of land to be acquiredor used and is therefore subject to planning

permission being granted and is not embedded inthe revised environmental assessment. The sheetwill be agreed and formalised through a triggeraction plan with 8-14 Fountain Green Square andplanning permission from the local authority. Theemployer shall use all reasonable endeavours toobtain planning permission.

Baseline noise monitoring shall be carried out for aminimum of 12 months before commencingconstruction activities.

In-road utility works in Chambers Street shall besurrounded by suitable portable noise barriers, eg,noise attenuating cladding may be fixed to anyportable steel open mesh fencing used.

Material onsite shall be compacted using machinerythat generates the lowest practicable vibrationlevels that can achieve the required level ofcompaction. Specifically, large twin-drum vibratingrollers shall only be used where vibration levels canbe controlled to less than the impact criteria set out
