Laing O’Rourke has won a £200M deal to work on the pioneering Swansea Bay Tidal Lagoon scheme.
The Dartford-based contractor was named as preferred bidder for the contract to build the turbine house and sluice structure block for the £1bn renewable energy project.
Tidal Lagoon Power’s bid to build a six-mile sea wall in Swansea Bay is subject to planning permission and negotiations over a contract for difference.
The 410m turbine house and sluice structure block will require up to 500 workers at peak construction, with many expected to come from South Wales.
Laing O’Rourke has named Arup as its lead design and engineering partner for the contract.
Tidal Lagoon Power director of engineering and construction Andrew McNaughton said: “Announcing that Laing O’Rourke is joining the team is a major step forward for the project.”
Laing O’Rourke project lead Jonathan Adams said: “From London 2012 to St Pancras International Station to Heathrow Terminal 5, we’ve been involved in the delivery of some of the UK’s most celebrated infrastructure projects.
“Today, the Swansea Bay Tidal Lagoon is the talk of the international construction industry and we are thrilled to be playing a part in its delivery.”
Contractors will be announced soon for the project’s marine works package and for provision of public realm ancillary works.
The procurement process for construction of a turbine assembly plant in Wales, and for the lagoon’s public realm and buildings work will get underway this summer.
