LAING O'Rourke is set to win a £70 million scheme to build a hotel on the Paradise Street redevelopment in Liverpool.
The company is already working on the mixed-use development and this latest deal will further cement its ties with the city.
Last week Grosvenor, the client on the entire Liverpool One development, which includes Paradise Street, admitted that costs on the £920 million job had blown the £1 billion barrier.
Grosvenor said building costs were up to £90 million higher than expected.
An O'Rourke source said: 'The site was effectively divided in half and the part we aren't doing is a lot harder technically, which is why we weren't really interested in it.'
The huge scheme will completely revamp Liverpool city centre in time for its year-long stint as European Capital of Culture in 2008. Grosvenor said it was still on track to complete the scheme in time for the celebrations.
