Code of Construction Practice 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.

1.1.1 This document forms the CoCPPart B for the project works at theHeathwall Pumping Station site and sets out detailed site-specific

measures including working hours, site set-up and servicingarrangements, taking into account environmental matters andconsultations with the London Borough of Wandsworth and otherstakeholders.

1.1.2 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.

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