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.

1.1.3 This document forms the CoCPPart B for the project works at theBlackfriars Bridge Foreshore site and sets out detailed site-specific

measures including working hours, site set-up and servicingarrangements, taking into account environmental matters andconsultations with the City of London Corporation and other stakeholders.

1.1.4 For ease of reference, this sets out site-specific issues and deviations fromPart A; therefore where no site-specific measures are specified, referenceshould be made to Part A.

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