Balfour Beatty has replaced Costain as preferred bidder for the tunnelling and marine works package on Hinkely Point C, worth more than £200M.
Costain has been working for client EDF on plans for three cooling tunnels for the £18bn nuclear power plant since 2013. Each is more than 9km in length and 7m diameter. But Balfour Beatty has now been named as preferred bidder for the four-year package.
It is the second major works package on the project for Balfour Beatty following its 2015 appointment to the £460M electrical works for the power station, a joint venture with NG Bailey.
“With our nuclear heritage dating back to the 1950s, reaching preferred bidder status on our second major package of works at Hinkley Point C is testament to both our expert engineering skills and our in-depth market knowledge,” said Balfour Beatty major projects business managing director Stephen Tarr.
“Hinkley Point C is a project which inspires collaboration by its very nature due to its significant scale and complexity. Our expert engineers will deploy heavy civil engineering skills and extensive knowledge of tunnelling.”
Cool water will be pulled in for the nuclear reactor via the three marine tunnels in the Severn Estuary before being cleaned, recycled and returned. Costain is still involved in the project, constructing a 490m long jetty in the Bristol Channel to transport aggregate for four batching plants to the Somerset site.
In 2013 Costain chief executive Andrew Wyllie said: “We are delighted that Costain will play a key role in delivering the secure, low carbon energy the UK needs for the future through our role as a Tier One contractor in the Hinkley Point C project.”
A spokesperson for EDF said: “Following a competitive process, the Hinkley Point C project team has awarded preferred bidder status to Balfour Beatty for the contract to construct the cooling water intake and outfall pipes for the station.
“This award extends Balfour Beatty’s role at HPC as they are already involved in civil and electrical works for the project.”
Costain declined to comment.
