processes (eg, land quality) where it was previously not explicitymentioned).

f. Approvals by a local authority for additional management plansincluding air quality, noise and vibration, lighting (whererequested), hoardings and tree work.

g. Inclusion of noise mitigation hierarchy and increased detail withrespect to noise mitigation. More detail was also added to covermonitoring and control of maximum noise levels.

h. Definitions added, or refined, where requested or deemed to addvalue.

1.1.9 In the CoCPPart Bs:

a. Commitments regarding approvals updated to be more specific,including hoarding design and lighting plan where requested.

b. Clarification and consistency checks with regards to push piling,anchor pilingand when this would be used.

c. Noise mitigation reviewed across the scheme, and added andrefined.

d. Review undertaken of each section to ensure clarity andconsistency.

e. SoCG reviews with local authorities to work towards agreement ofthe items included.

Areas of disagreement

1.1.10 After the review and update of the CoCPdocuments, there remain anumber of areas where agreement has not yet been reached. Theseare mainly points where it was not considered to be appropriate tomake a particular change to the CoCP.

1.1.11 The areas not agreed include:

a. Approval of the CEMP by the local authoritiesThis is not agreedbecause it is believed that all of the relevant parts of the plan thatrequire approval are already given for approval elsewhere. Itshould be noted that at the 29January 2014 meeting with the local

planning authorities, several of the boroughs did say that theywere now happy that they did not need to approve this document(as they had been given sufficient other approvals, eg, noise andvibration, air quality).

b. Site layout approval by local authority, of each phase of projectsconstructionThe London Borough of Southwark, in particular, isrequesting this. It has been agreed in the CoCPPart B forChambers Wharf, that aside from all of the relevant managementplans being for local planning authority approval, the site layoutwill be planned in consultation with the local planning authority.

c. Approval by local authority of the height and external appearanceof some temporary buildings and structures In general, where

there have been requests, commitment has been made to theappearance of these within the relevant CoCPPart Bs.

d. Extent of involvement of community liaison group in reviewprocess of working hours and enforcement.The remit of thecommunity liaison group has been expanded in the CoCPPart A.

e. Approval of river works by local authority in addition to the PLAand MMOIt is our view that the local authority will have relevantapproval rights through the Section 61 process.

f. TfL has requested traffic management plans to be approved by thehighway authority rather than the local planning authority.Thiswas discussed in the recent EHO forum and a number of localauthorities have confirmed the current proposal is preferable tothem (including City of London, Londond Borough of Ealing,London Borough of Southwark and Westminster City Council).

1.1.12 There are a number of comments and drafting points that have beenreviewed, and whilst the principle has been agreed, the location whereit is covered may vary. This includes, for example:

a. Publishing details of all complaints on websiteThe summary willbe issued to the local authority and relevant summaries will bemade available on the website (please note: the exact details ofthe website are still to be determined).

b. Details on proposed project hubs for community liaisonTheseare covered in the relevant Section 106 deeds.

c. Amendments to the considerate contractors scoring requirementsThe suggested amendments received were acknowledged in theEHO meeting on 29 January 2014, to be incorrect, and that theexisting text was appropriate.

d. Additional items on workplace healthThe CoCPis a documentthat deals with construction effects, not worker health. This is amatter dealt with in contractual documents, and under health andsafety legislation.

e. Specific local issuesIt is envisaged that these will be resolvedthrough the discussions on the individual SoCGs with the localplanning authorities (eg, London Borough of Richmond uponThames requests no lorry movements at their sites during eveningpeak hours in addition to the morning peak hour that is alreadyagreed).

Finalisation work

1.1.13 During the time before the final versions of the CoCPare submitted on12 February 2014, any further items that arise from the examination(noise specific hearing, and development consent order hearings) inthe week commencing 3 February 2014, will be considered forinclusion. A final proof check review (including another cross-check of

development consent order Requirement references, and an update tothe general controls section) of the documents will also be carried out.
