Roads Policy & Procedure Guide: RsPPG E030 Major Works Schemes: Inception to Construction.

The Investment Decision Maker (IDM) role for Strategic Road Improvements and other Major Works road projects had been the Roads and Rivers Management Group and RSPPG_E030 was established on that basis. Latterly, with the standing down of the role of the Roads and Rivers Management Group as IDM, the role of the IDM will now vary with each decision stage. Taking direction from senior management, in particular the Transport and Road Asset Management (TRAM) Deputy Secretary and Director of Major Projects, a revised IDM process has been developed, which will be reflected in the updated RsPPG.
