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

Compromise for 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 applicable projectwide.

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

1.1.3 This document forms the CoCPPart B for the project works at the PutneyEmbankment Foreshore site and sets out detailed site-specific measuresincluding working hours, site set-up and servicing arrangements, taking into

account environmental matters and consultations with the London Boroughof Wandsworth 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 PartA.

1.1.5 A plan showing the location of the site is shown in Figure 1.1 overleaf.
