The UK’s biggest contractors are gearing up to bid for the £260m Barking Riverside rail contract in east London.
Five joint ventures and three individual contractors look set to battle it out to build the 4.5 km Overground line and the Barking Riverside station.
Construction News understands that JVs between Balfour Beatty / Atkins, Bouygues TP / Murphy, Skanska / Colas Rail, Kier / Alstom and Taylor Woodrow / Amey are all preparing bids.
Carillion, Hochtief and Morgan Sindall are also understood to be interested in the contract, which will extend the Gospel Oak to Barking line.
Bam Nuttall considered a bid for the work but has since pulled out.
The list of interested contractors comes a week after Transport for London announced it would commence bidding for the line.
TfL began seeking expressions of interest for the project last year and the contractors are now in the process of preparing PQQs ahead of the 21 September submission deadline.
Firms will be shortlisted in November, with ITTs expected to be issued in August 2017.
The contract will be awarded in January 2018, with the line and new station expected to be fully operational by 2021.
Initial designs for the project have been carried out by Atkins, with Arcadis and architects Weston Williamson+Partners set to take over.
Six months ago TfL approved £172m of funding for the line, paving the way for construction to begin and unlocking the residential development.
Developer Bellway Homes had planned to build 10,800 homes on the site in 1994 but these proposals were shelved due to the lack of transport links.
Bellway will remain a development partner on the project.
L&Q also agreed to commit £70m to the construction of the new station as part of the deal.
Without the development of the line, the number of homes that can be built on the site is capped at 4,000.
TfL submitted a Transport and Works Act Order to the transport secretary in March, with a decision expected later this year.
A TfL spokeswoman said: “We have had a really positive response to the Barking Riverside Extension OJEU notice and look forward to receiving submissions from interested suppliers in September.
“We can’t confirm at this time as we don’t know who will be submitting PQQs until the submission deadline in September.”
