McLaren Construction Group surged to the top of the contractor league tables in February after landing a £500m deal to build a major datacentre campus in East London.
The firm has secured a shell and core contract to deliver the first of three giant datacentre buildings at Ada Infrastructure’s Docklands campus, propelling it to the number one spot in the monthly rankings.
John Sisk & Son ran McLaren close in a strong month for big-ticket project wins. The contractor secured two major schemes worth an estimated £430m combined, including further work on the Birkenhead Waterfront regeneration and a health innovation campus for the University of Birmingham.
Across the wider market, the top 50 contractors saw new orders ease back slightly in February, with total contract awards falling to £4.1bn from January’s strong £4.58bn haul, which had given the year an early boost.
In the rolling 12-month rankings, STRABAG held top spot, buoyed by its £3bn long-term Haweswater Aqueduct Resilience Programme contract.
Private contractor Bowmer & Kirkland climbed to second place for the first time, supported by 62 contract wins over the past year, according to data compiled by Barbour ABI.
Mace Group held third place in the annual rankings, while McLaren’s Docklands datacentre win pushed it into fourth, displacing Balfour Beatty.
