The overall Weaver to Wavertree Re-signalling scheme is part of Network Rail’s £340m Liverpool City investment programme. It comprises re-signalling work on 16 miles of track between Edge Hill Station in the north and Winsford in the south to remove five signal boxes, with control moving to the new state-of-the-art Manchester Rail Operating Centre (ROC), part of Network Rail’s wider modernisation programme.

The aim of the GRIP 4 development and early GRIP 5 stage design for Weaver to Wavertree Signalling Renewals was to eliminate the risk of scope change in subsequent GRIP stages, including:
• Elimination / reduction of construction risks associated with Signalling AIP design.
• Achieving AIP sign off for Telecomms, E&P, Civils and Track disciplines.
• Define construction and testing requirements for Signalling, Telecomms (including FTN), Plant, OLE and Lineside Civils.
• Achieving full understanding of interlocking complexity and controls, Zone controller system architecture and fringe location works.

Tier One Commercial Management were engaged after project commencement to support Project Management to manage change, value and mitigate risk and negotiate settlement of the final account, operating under the Professional Services Framework.
