Tideway is a £3.8bn upgrade to London’s Victorian sewer system. Construction to build the 25km Thames Tideway tunnel operates across 24 sites throughout the city. Works included brownfield site remediation, ground improvements, marine cofferdam installations, diaphragm walling to shafts, TBM procurement, tunnelling works and associated structures and landscaping.


GVE became involved on the East Section Contract (2017-2019) working for the Joint Venture Contractor on an NEC3 contract. We provided a change manager for the main tunnel sites carrying out contract administration and management of compensation events through pricing to implementation of additional sums and movement of key dates and completion.


In 2020, GVE provided a senior surveyor for commercial management of the main tunnel drive site located at Chambers Wharf, Bermondsey. This role included commercial management of packages to support tunnelling activities including close out of disputed commercial matters with subcontractors.
