Skanska is to receive an extra £50 million (US$64.7 million) under its existing contract for the HS2 high-speed railway, as part of the Skanska Costain Strabag joint venture.
The award relates to planned and agreed changes to the scope of the works under the contract.
The total contract is now worth around £1.4 billion (US$1.8 billion) to Skanska and involves the design and construction of major tunnels in the southern section of the project.
Two tunnel boring machines (TBMs) started operations in late 2022, with a further two which started operations in early 2024 and a total of four TBMs now operational. These TBMs are building 13.5 kilometres (8.4 miles) of twin bored tunnels between West Ruislip and the new high speed rail super hub station at Old Oak Common.
A fifth TBM, to create a logistics tunnel, completed its journey in January 2024. Two final TBMs that will complete the drive to London Euston are currently in manufacture.
