Transport for London is looking for a contractor to build a £55m passenger tunnel for Crossrail at Paddington.
The winning firm will design and build the 100 m-long tunnel, which will link the Crossrail and Bakerloo Line platforms at Paddington station.
The deal is worth £30m to £55m.
Prequalification questionnaires must be submitted to https://eprocurement.tfl.gov.uk/epps/home.do by 25 November at 5pm.
The news comes shortly after Vinci and Balfour Beatty picked up lucrative Crossrail contracts earlier this month.
Vinci will upgrade 13 stations on the western section of Crossrail’s Acton Main Line to Maidenhead in a contract estimated to be worth around £100m.
Balfour Beatty won a £64m deal to install electric overhead line equipment on a 12.5-mile section of the Great Western Main Line between Stockley Junction and Maidenhead across all tracks, facilitating the delivery of Crossrail services as well as new high-speed Intercity Express trains on the Great Western route.
