Great Western Electrification Substations

In September 2015, Rail Civil Engineering Contractor – BCM – were awarded a significant substation civils project on Network Rail’s Great Western Electrification infrastructure project on the lines between Reading and Bristol stations.

These works form part of the wider Great Western Route Modernisation, which involves complex infrastructure works, new trains and service changes. These aim to improve services along the rail route, which connects London with West and South West England and South Wales.

Contracted by electrical systems contractor UK Power Networks (UKPNS), BCM’s substation civil engineering scope covered substation bases and associated minor civils at a multitude of sites spread over a large geographical area. Scope included both small and large-scale substations ranging in size from 200m2 up-to nearly 2000m2.

Due to programme requirements, many sites were required to be completed concurrently, which necessitated the need for BCM to set-up a number of strategic hubs, to effectively manage project logistics, specifically for the large quantum of both mechanical and self-operated plant and also construction materials.
