Dragados and a Costain/Vinci joint venture are to battle it out to be preferred bidder for London Underground’s (LU’s) complex £600M Bank station upgrade, NCE can exclusively reveal.
It is understood that LU has decided to take both teams through to the next stage of negotiations rather than announcing a single preferred bidder.
Costain is in joint venture with French contractor Vinci and has brought in Mott MacDonald as its consultant, while Spanish giant Dragados is bidding on its own.
The move means that joint ventures of Bam Nuttall, Ferrovial and Kier and the MBA consortium of Morgan Sindall, Balfour Beatty and Austrian tunnelling contractor Alpine Bemo have been eliminated. MBA had brought in Arup as consultant.
The project will create a new ticket hall at surface level and includes the diversion of around 570m of the southbound Northern Line running tunnel plus the formation of a new southbound platform, south west of the existing platforms.
The contract is the first to use LU’s new Incentivised Contractor Engagement model. This aims to reward bid teams for money saving ideas even if they ultimately lose out on the construction contract.
The four bid teams have been working on designs since LU issued a prequalification notice in November 2011. They were shortlisted in April 2012 and then entered several months of structured dialogue before tender documentation was issued in November.
Tenders were returned in February and since then LU has been evaluating them ahead of a preferred bidder announcement.
This preferred bidder was then to have entered an integration phase ahead of contract award in July.
