The design and build project was awarded following a mini-competition using LU’s Civils and Tunnelling Works framework, which over eight years is worth up to £350m.

The 18-month Train Modification Unit project will involve building a 160m long train maintenance building, incorporating four pitted rail tracks and an accommodation block providing welfare and office facilities for 100 staff.

The project also includes the installation of new tracks and turn outs that will connect into London Underground’s existing network.

The joint venture team is working with one of Morgan Sindall’s sister companies, design and engineering company BakerHicks, on the design of the project.

Andrew Jellis, managing director of Rail at Morgan Sindall, said: “We are looking forward to starting on site and setting the standard for our other works as this framework gathers pace.”
