A design viewed as “unbuildable” by many building firms, Advanced Substructures entered partnership with PACT construction to deliver the 6 floors of premium office space, a café/lobby level and 2½ full site basement levels for this prestige project.
The difficult site and several distinct challenges required careful consideration of the sequence and methods of construction used.
This stunning project was commenced September 2015 and completed in 2017.
