HS2 has called up contractors to bid for its two big London stations with the promise of nearly £3bn of work.

Four firms will be separately shortlisted to bid for Euston and Old Oak Common stations with prequalification documents due in by early October.

Under present plans the management contract for each station will be handed to different firms although contractors are free to bid for both.

The prequalification process has opened a month after HS2 revealed shortlisted designers for its stations. These  include, Arup, Mott MacDonald, WSP, Arcadis and a Jacobs/BuroHappold/Idom joint venture.

Euston station has an estimated construction cost of £1.65bn and has made some contractors wary about bidding for the giant build contract, according to industry sources.

Euston HS2 stands out as the most complicated contract to bid for because the full scope of works will not be established until the Autumn.

The station redevelopment will also be completed in two distinct phases, the first starting in September next year and the second due to start 2026 and run to 2033.

The extra scope for phase one could include enabling works for overstation redevelopment.

Five bidders have already been named as in the running for Euston Master Development Partner contract. These include: Westfield Europe, Euston Regeneration Partnership (led by Argent), Canary Wharf Group, Land Securities and Lendlease Europe.

Old Oak Common station in North West London will also include options to include enabling works for overstation development.

As plans stand at present the station is expected to cost around £1.3bn to deliver with a contractor being signed up in September 2018.

On both contracts HS2 is reserving the right to require guarantees, bonds, collateral warranties, including  step-in rights to subcontract works packages.

Formal invitation to tender will be issued to shortlisted contractors next January. Further information is available from the HS2 eSourcing portal.
