The Hirwaun Generating Station Order 2015

Construction traffic

13.—(1) No numbered work of the authorised development other than tree felling is to commence until a construction traffic management plan covering that numbered work has been submitted to and approved by the relevant planning authority in consultation with Welsh Government Transport. The construction traffic management plan is to detail the proposals for the movement of construction traffic and abnormal indivisible loads associated with the authorised development and is to include—

(a) construction vehicle routing plans at 1:2,500 scale for all traffic including abnormal indivisible loads showing—

(i) swept path analysis from the point of entry onto the highway network to the Order land;

(ii) highway mitigation in respect of any identified constraints on vehicle movements such as embargo periods, route traffic sensitivity, temporary road works and other highway restrictions to be developed following consultation with the South Wales Trunk Road Agent, and, where relevant, referring to supporting HD19/03 safety audit documentation (as contained within the Design Manual for Roads and Bridges Volume 5 Section 2 Part 2 and as amended or replaced); and

(iii) land ownership boundaries for any required holding areas, passing areas and layover areas;

(b) evidence of appropriate trial runs that demonstrate the suitability of the route from point of entry onto the trunk road network to the Order land for the proposed types of abnormal indivisible loads;

(c) site access plans at 1:2,500 scale that include supporting HD19/03 safety audit documentation (as contained within the Design Manual for Roads and Bridges Volume 5 Section 2 Part 2 and as amended or replaced);

(d) proposals for the management of junctions to and crossings of the public highway during delivery of abnormal indivisible loads;

(e) proposals for the scheduling and timing of movements of delivery vehicles, to be developed following consultation with the Welsh Government and potentially affected undertakers, and, in relation to any abnormal indivisible loads, details of vehicle parameters, number of vehicles in convoy size, dimensions (width, length, height) and weight (total vehicle with load and axel loading);

(f) details of escorts for abnormal indivisible loads highlighting where and when along the route private vehicles, banksman and Police vehicles escorts will be used (including emergency contingencies);

(g) proposals for temporary warning signs and banksman for abnormal indivisible loads, including provision of plan drawings and associated traffic signs schedule highlighting locations along the route where temporary traffic management (including cones and temporary signs) needs to be deployed;

(h) a methodology for undertaking a conditions survey of Main Avenue, Fourth Avenue and any other land identified during the trial runs that may have a constraining impact on the abnormal indivisible load movements including the timescales for undertaking the surveys and the method(s) of reporting the findings to the relevant planning authority, comprehensive photographs and potential compensation arrangements;

(i) details of any temporary or permanent improvements to highways;

(j) proposals for the making good of any incidental damage to highways by construction traffic associated with the authorised development including street furniture, structures, drainage features, highway verge and carriageway surfaces;

(k) proposals for traffic management controls (such as temporary signals), diversion routes and signage required during any of the activities, operations or works set out in Schedule 4; and

(l) proposals for the notification of occupiers of land adjacent to the construction traffic route of the scheduling and timing of abnormal indivisible load movements from the point of exit from the trunk road network to the Order land.

(2) The construction traffic management plan must be implemented as approved.

(3) During the operation or decommissioning of numbered work 2 no abnormal indivisible loads must be transported into or out of the Order land without the prior written approval of the relevant planning authority in consultation with Welsh Government Transport.
