Chambers Wharf

Chambers Wharf:

Chambers Wharf in Bermondsey is one of the main drive sites for the tunnelling and will launch and receive tunnel boring machines, Selina, Ursula, and Annie. The shaft will be more than 60m deep, with new land being created in the river Thames to allow space to work.


Milestones to be reached this year: Diaphragm wall works are now complete allowing the excavation of the tunnel shaft to begin (currently working 24hrs 5 days a week with 2 x 25t zero tailswing excavators on shaft excavations).

  • 10,360 recorded man hours to date
  • 26 recorded hires


  • Early engagement with all of the above sites has ensured that Lynch have played a part in the Thames Tideway project staying on track to deliver in 2024.
  • The use of innovative technologies, telematics reports, and barge loading to transport materials have all contributed to keeping congestion, disruption, and pollution to a minimum, whilst also saving the client time and money.
