The contract is subject to a final decision from EDF to proceed with the new nuclear project which will be built by Laing O’Rourke.
Construction of the 500 metre-long jetty will employ 120 people at its peak and it will allow materials for the proposed Hinkley Point C station to be delivered by sea.
After the completion of the power station, the jetty will be removed and the area restored.
Graeme Barclay, Regional Director, Balfour Beatty said: “We are delighted to be awarded this contract for the delivery of what will be an important scheme for the South West region.
“Already an established regional business, we are fully committed to the community and welcome opportunities to employ local workforce, working collaboratively with EDF to successfully deliver this challenging project.”
Nigel Cann, Hinkley Point C Construction Director at EDF Energy said: “The temporary jetty contract will help us get to work quickly and will reduce the impact of the construction of the proposed new nuclear power station on both the local community and the environment.”
