Costain, an infrastructure solutions provider, has been contracted to provide the mechanical and electrical (M&E) systems for the UK’s new High Speed Two (HS2) rail project’s tunnels and lineside areas.

The contract, valued at a minimum of £400m ($421.01m), encompasses the design, installation, testing, and commissioning of tunnel ventilation and M&E systems.

Costain is set to commence the contract in the first quarter (Q1) of 2025, with a scheduled duration of seven years. The agreement includes an option for further extension.

The scope of work also includes the installation of services within the tunnels, cross-passages, and low-voltage power services and distribution for the open sections of the route.

Costain plans to leverage its expertise in complex project and programme delivery, systems engineering, integration, and supply chain collaboration to execute the contract.

Drawing on its experience from other infrastructure projects such as Crossrail and the London Power Tunnels, Costain aims to meet the demands of the HS2 project.

The company has been proactive in adopting new technologies such as AI robotics to automate and enhance the efficiency and safety of tunnel M&E installations.

These technological advancements have been developed further to include real-time digital assurance at the point of installation. This aims to optimise cost and efficiency during tunnel fit-outs.

Costain CEO Alex Vaughan said: “Costain has a longstanding involvement with the UK’s largest strategic infrastructure programme and this new award is testament to the strength of our collaborative and successful relationship with HS2. Our teams will draw on their experience and expertise in delivering world-class M&E systems, for example on Crossrail, and will use the latest technology to drive efficiency.

“HS2 will be transformational for UK connectivity, freeing up capacity on the existing rail network and alleviating road traffic and congestion. It’s a project that will continue to create jobs, develop skills and drive prosperity long after construction.”
