Contract award is scheduled for summer this year (2015), once investors ready to finance the project are chosen and announced. Main construction is programmed to start in 2016, with completion of the project due by 2023.

Andy Mitchell, Chief Executive at Thames Tideway Tunnel, said: “We have selected our preferred bidders to work on the three main works packages because we have absolute faith in their ability to carry out these major pieces of work safely, considerately and sustainably and we are looking forward to working with them to offer the thousands of jobs that will help make this project a reality.”

A separate company known as an Infrastructure Provider, with its own licence from the UK Government water industry regulator OFWAT, will manage the construction, financing and delivery the project.

In June 2014, TunnelTalk published the list of groups that prequalified to bid on each of the construction lots (Table 1). Each contract comprises tunnelling distances of approximately 7km, 13km, and 5.5km for the West, Central and East contracts respectively.
