Aecom wins Thames Tideway Tunnel design contract

Lee tunnel 3.2

Aecom is to design the central section of the Thames Tideway Tunnel, winning one of three major work packages on the super sewer project.

It has been appointed by a Ferrovial Agroman and Laing O’Rourke joint venture as the lead design consultant for the section.

Aecom will deliver design services for the 12km (7.5 mile) section from Carnwath Road in Fulham to Chambers Wharf in Bermondsey. It is the largest part of the route. Construction will start next year and it is expected to be completed by 2023.

Two tunnelling machines going east and west will be launched from the Kirtling Street shaft in Battersea. Eventually to the east the tunnel will connect to the Lee Tunnel, which will transfer the sewage to Beckton Sewage Treatment Works. Aecom also provided design consultancy services for the Lee Tunnel (pictured), which is due to be completed next year.

Aecom head of tunnels in Europe Steve Woodrow said: “Tideway is one of the UK’s most important new infrastructure projects, which will dramatically improve the water quality of the River Thames and give London a wastewater system it can rely on. Aecom’s tunnelling team brings its recent experience delivering the Lee Tunnel to this key civil engineering project.”

Ferrovial Agroman and Laing O’Rourke JV project director Peter Main said: “The central section of Tideway is a major feat of engineering and Aecom brings valuable expertise in tunnelling design services that will enhance and strengthen our delivery team.”
