Interior has beaten off a challenge from Mace to win a £40m construction management job to fit out a stand at Ascot racecourse in Berkshire.
The firm is understood to have won the two-horse race late last month. The Ascot job is part of an overall £180m revamp of the racecourse, designed by sports specialist HOK
Laing O'Rourke won the £50m package to build the shell and core of the stand at the end of last year. It beat off bids from Mowlem, Sir Robert McAlpine and Multiplex.
Work is not due to begin on the development until next year. Ascot this week dropped plans for a six-storey hotel and health club.
Interior has also won several other contracts, including a £35m further education campus at Telford College, Edinburgh, and the £15m refurbishment of the Royal Lancaster Hotel in London.
