Tideway has said that it has completed excavation of the first tunnel boring machine launch shaft on London’s £4.2bn sewer project.

Excavation started in November last year

Work to construct the 60m deep, 31m diameter Kirtling Street shaft started in June last year with excavation getting underway in late November.

The shaft on the former Cemex concrete batching plant site in Nine Elms, to the south of the River Thames, is being constructed by Flo, which is a joint venture of Ferrovial Agroman UK and Laing O’Rourke Construction.

Tideway central delivery manager Chris Darton said: “Completing the shaft marks a major milestone in the delivery of the super sewer which will clean up the River Thames. The team worked tirelessly to complete the excavation and we are now looking forward to welcoming our giant tunnel boring machines to site ahead of tunnelling starting later this year.”
