The new Forth Replacement Crossing will be a cable-stayed bridge carrying a motorway with two lanes of traffic plus hard shoulder in either direction.
Supported by three single column towers, the completed structure will be 2.7km long including its approach viaducts.
Final design and construction is being undertaken by the Forth Crossing Bridge Constructors consortium, comprising Hochtief, Dragados, American Bridge International and Morrisons Construction.
The client is the Scottish Government. Richard Burmeister, managing director at Strainstall, said: “This contract is a further demonstration of the international name and reputation of Strainstall in the provision of structural health monitoring both for new-build civil engineering projects as well as the protection of important heritage structures.”
The contract announced will see James Fisher and Sons plc, a subsidiary of Strainstall, provide sophisticated monitoring technologies, allowing the bridge’s precise movements and loadings to be monitored in real time, during the construction as well as throughout the life of the new bridge.
