A fifth bidder for Crossrail’s major tunnelling contracts has emerged as invitations to tender have been issued today.
A joint venture between Dragados, owned by leading Spanish firm Grupo ACS, and John Sisk & Son has been shortlisted for contracts C300 and C305 together with four other consortia already known to be in the running.
Balfour Beatty/Beton-und Monierbau/Morgan Est/Vinci Construction Grands Projets, known as BBMV, Skanska/Costain/Bilfinger Berger, Laing O’Rourke/Bouygues and Kier/Bam Nuttall/Ferrovial have also been invited to tender.
C300 covers the construction of the 6.2 km stretch of tunnels from Royal Oak Portal, west of Paddington Station, through to the new Crossrail Farringdon Station in the City.
Work to be carried out during the 58-month job also includes the construction of a shaft at Fisher Street, but the construction of the Royal Oak Portal will be let separately.
Meanwhile the 66-month C305 covers the construction of an 8.3 km tunnel section from a launch chamber at Limmo Peninsular through to the new Farringdon Station, as well as 2.7km of tunnel from a launch chamber at Stepney Green to the Pudding Mill Lane Portal.
A 0.9 km section from the launch chamber at Limmo Peninsular through to the Victoria Dock Portal is also required.
Tunnelling is scheduled to commence in late 2011 in support of the Crossrail programme milestones.
