John Sisk's UK expansion plans have been boosted by over £260m-worth of contracts wins during the past nine months.
The Irish-owned construction group posted a UK turnover of £161m in its last financial year, ending 31 December 2009, a sharp fall on the previous year's £226m.
John Sisk is building two of the blocks in the Olympic Village at Stratford (pictured), and restoring the £51m Weston-Super-Mare pier.
It is currently bidding for the £65m Forth Bridge Crossing junction upgrade, and a £45m office scheme at Birmingham Snow Hill station.
"This market is very important to the group and one in which John Sisk is doing very well. We have had a significant number of recent project wins across Britain and we have redeployed forty of our Irish employees to support them with the increased workload," said Sisk Group CEO Liam Nagle.
"While construction in Ireland has slowed, our construction business in Britain is making great strides. We are also continuing to grow our healthcare interests and have diversified into distribution and other sectors."
Paul Wilson, managing director of John Sisk in the UK, said, "We are focused on delivering a continued period of further growth."
