Initial Brief

Following on from the successful Bristol Area Signalling Renewals and Enhancements (BASRE) scheme, Bristol East Junction was conceived to rationalise the complex and difficult to maintain layout to the junction.

The work enhanced the capacity of the eastern approach to Bristol Temple Meads Station, as well as enabling other parts of Bristol’s ‘masterplan’ including the Eastern Entrance and Metrowest projects.

WCL were engaged to provide project management and consultancy services from GRIP 3-8 including tendering support, management and commissioning support.

Challenges

The biggest single challenge of these works was ensuring the signalling works were fully integrated with all the other disciplines which are managed by the client (Network Rail) on a hub and spoke arrangement, with designs reaching maturity at differing times.

Delivery of the scheme was staged to reduce the final blockade durations, starting in Aug 2020, and culminated in a 60 day blockade of the station in the summer 2021, with phased hand back and multiple entry into service points – a significant integration effort.

Outcomes

WCL collaborated with Alstom to construct an effective id for the GRIP 4 (single option development) scheme, managing it to a successful completion.

We led on the tender for Alstom for the GRIP 5-8 (detailed design, construction test and commission, hand back and close out) scope. We then provided lead project management consultancy services throughout the design, build and successful commissioning all of the major stages.

WCL also provided additional commissioning management and administration support throughout the shutdown period of works, ensuring a successful conclusion to the works.

The major commissioning works have now been successfully completed with, final additional permissive move data and testing completed in 2022.
