The contractor soared to the top of the contracts league after securing the £700m Wanda project and another London high-rise scheme, valued at £100m, called the Stage, according to construction information specialist Glenigan.
The brace of high-rise projects also catapulted Multiplex up the 12-month rolling league of new work from 21st place to seventh.
Lendlease came in second with the Google HQ project at the Kings Cross Goods Yard in London.
