Combwich Wharf Development
HOCHTIEF is refurbishing the existing wharf at Combwich, which will be used to bring in very large loads during construction of the new Hinkley Point C nuclear power station. Our scope of works includes an initial Early Contractor Involvement (ECI) and site investigation phase (Phase 1), followed by construction works to renovate the existing wharf (Phase 2).
- Early contractor involvement
- Site investigation
- Wharf refurbishment
- New hard standings
- Haul road loading facility
- Berthing pocket
During Phase 1, we successfully completed site investigation works, drilling six boreholes and carrying out Cone Penetrometer Testing to determine the geotechnical engineering properties of the soil.
Throughout the site investigation, tidal conditions and storms presented environmental and safety challenges for access and barge stability. To mitigate the risk of delays caused by the weather, we assembled the jack up barge over the old wharf, rather than floating it down to Combwich from Avonmouth by sea. Our careful structural analysis of the existing wharf made this possible and ensured that we completed the works as planned.
We used acoustic barriers to minimise noise during the borehole drilling. This ensured that we met strict environmental targets, and we built excellent relationships with local stakeholders, especially the Combwich Motor Boat and Sailing Club who share the wharf with us.
We are currently reviewing the client’s design and providing value engineering and buildability advice to optimise costs for the construction phase.
