The government has put firms on notice for a £360m design and engineering job for the programme of works at Euston station and the site’s huge surrounding mixed-use development.

The Department of Transport (DfT) will launch a preliminary market engagement exercise for the five-year role next month, with a full contract notice to be published on 1 May next year.

The appointed team will work with the Euston Delivery Company (EDC), a government-backed entity established to oversee a programme of upgrades to the existing mainline station, enhancements to the London Underground interchange and linked bus and taxi facilities.

The EDC is also overseeing the development of the surrounding residential and commercial district, which landowner Network Rail has previously suggested will include a new life sciences cluster as an extension of the nearby King’s Cross Knowledge Quarter.

The job will not include the new central London terminus for HS2, which is part of the wider Euston masterplan but is being delivered separately through a private finance partner.

In a preliminary market engagement notice posted on Friday, the DfT said the appointed EDC design and engineering partner will work closely with Euston masterplanner Lendlease and its appointed design lead Allies & Morrison on the development of the programme.

Work is expected to include scheme design on behalf of EDC, large-scale transport engineering design, architectural masterplanning, programme planning and scheduling, cost control, strategic planning and delivery oversight.

The appointed supplier will need to have “proven experience in delivering designs for complex, multi-modal transport infrastructure” and the ability to “shape and translate early-stage design into feasible and buildable solutions within constrained cost and programme parameters”, according to the DfT.

A market engagement exercise conducted jointly by the DfT, EDC and HS2 will be held from the middle to the end of November with the aim of better understanding market interest in the contract and to explore risk appetite, proposed timelines and delivery structures.

The exercise will also include potential bid structures for the job, which would likely be delivered by a consortium.

Construction of HS2’s Euston terminus was paused by Rishi Sunak in 2023 amid spiralling costs. Work on the line’s tunnel approaches by the SCS joint venture between Skanska, Costain and Strabag is set to begin next year when the TBMs launch. A service tunnel has been dug to the Willesden logistics hub to take the spoil from the tunnels out to waiting trains.
