Mace is main contractor on the 220,000 sq ft Hanover Square scheme for Great Portland Estates.
In its annual results announcement today the developer said: “The delayed opening of Crossrail has been beneficial to operations on site preventing the need to construct the building over a fully operational station and progress has been rapid.
“The steel frame is complete, the majority of the modular cladding has been applied and the building topped out in April 2019.”
Crossrail was due to open in December 2018 but will now be completed by October 2020 at the earliest and without Bond Street Station.
The west London station is lagging behind the rest due to “design and delivery challenges” faced by contractor Costain Skanska Joint Venture.
