Fabricating and erecting 740 tons or so of structural steel required for the Aga Khan Museum in Toronto posed a series of unusual hurdles.
One of those hurdles was how to attach the steel frame for the second floor to the first floor — an inward-sloping poured-in-place concrete wall.
“Our connections to the concrete wall had to be fairly substantial to transfer the forces to make the building stand up,” says Rob Morrison, project manager, Benson Steel, supplier/erector for the job.
Another challenge for the big steel fabricator/erector was the installation of six steel-framed hexagonal skylights. Made of an HSS steel frame, the offsite-assembled 4.7 by 4-metre shaped skylights had to be carefully erected and placed on sloped sections of the roof, says Morrison.
The museum’s new auditorium features a steel “dome-like” roof. The 18 by 18-metre frame was assembled in segments on site and hoisted by crane into place.
