Code of Construction Practice Part B 1
1 Introduction
1.1 General
1.1.1 All works covered within this document are to be managed and performedto the culture within the Thames Tideway Tunnel vision of Zero Incidents,Zero Harm, Zero Compromise.
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 measures,where there are deviations from the general requirements indicated inPart A.
1.1.3 This document comprises the CoCPPart B for the Thames TidewayTunnel project works at Blackfriars Bridge Foreshore site and identifies thedetailed site-specific measures including working hours, site set up andservicing arrangements, taking into account the environmental issues andconsultations with the City of London Corporation and other stakeholders.
1.1.4 For ease of reference the CoCPPart B mirrors the headings in Part A.The CoCPPart B sets out site-specific issues and deviations from Part Aso where there are no site-specific measures reference should be made tothe measures set out in Part A.
1.1.5 A plan showing the location of the site is shown in theFigure 1.1 below.

(a 'Site Hours Variation Request' -justifying the work and methods). This includeswork categorised in CoCPPart A as extendedworking hours, continuous working, out of hours,possession working, tidal working and short noticeworking.
Site layout The temporary works construction within the river
willshallminimise the works within the navigationalchannel. The detailed methods are to be agreedwith the Port of London Authority, EnvironmentAgency and Marine Management Organisationsubject to required licenses, navigational riskassessments and consents.
