Thames Tunnel contractors shortlisted

Thames Water has today named the eight contracting joint ventures that will be tendering for the £2.3bn main construction work of the Thames Tideway Tunnel.

The shortlisted contractors will be bidding for one or more of the three work packages which have been split into geographical sections of west, central, and east. 

The shortlist:


  • Bam Nuttall, Balfour Beatty, Morgan Sindall JV
  • Costain, Vinci, Bachy JV
  • Dragados, Samsung JV
  • Ferrovial Agroman, Laing O’Rourke JV


  • Bam Nuttall, Balfour Beatty, Morgan Sindall JV
  • Costain, Vinci, Bachy JV
  • Ferrovial Agroman, Laing O’Rourke JV

  • Bam Nuttall, Balfour Beatty, Morgan Sindall JV
  • Bechtel, Strabag JV
  • Bouygues Travaux Publics
  • Costain, Vinci, Bachy JV
  • Hochtief, Murphy JV

The three main works packages are worth a total of up to £2.3bn – west (£300M - £500M), central (£600M - £950M) and east (£500M - £800M).

The release of the three tenders are being staggered. West will be tendered first, then east, then central. This will be done between November 2013 and April 2014, before the preferred bidders are announced in early 2015.

The Thames Tideway Tunnel is a major new sewer that will help tackle the problem of overflows from the capital’s Victorian sewers and will protect the River Thames from increasing pollution for at least the next 100 years.

The Development Consent Application is currently being considered by the Planning Inspectorate and, subject to consent being granted, construction on the project is due to start in 2016 and will involve 24 construction sites across London.

The project is expected to be financed and delivered by an independent Infrastructure Provider (IP), with its own licence from Ofwat. Thames Water, Government and Ofwat are continuing to work together to finalise the financing arrangements for the project.  Procurement of the new IP is expected to begin in 2014 and is anticipated to take between six to nine months.
