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 the PutneyEmbankment Foreshore 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 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 Part A.

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