Caunton had the pleasure of contributing to the construction of EDF Energy’s Hinkley Point C nuclear power station in Somerset. The company was awarded the contract to provide a structural frame for a factory building at Bristol Port, Avonmouth, which is now used to manufacture precast concrete tunnel segments.
The segments have formed the tunnels to carry cooling water for the power station. Three tunnel structures were required, two intake and one outfall.
These have been constructed approximately 20m beneath the sea bed. Caunton was involved in the construction of the factory that will make the tunnel segments, which weigh between 4.2 and 4.8 tonnes each.
The steel frame for the building was designed, manufactured and erected by Caunton. It is 14.5m in height and 36m wide by 150m long. Caunton is responsible for not only the near 500te steel frame but the cladding and the doors. The design is to EC3 to accommodate the crane loadings.
