Since the September installation of a tower crane atop the 1968-built Global House office building at 480 University Avenue, facade removal and structural reinforcement work have been progressing smoothly at the site of Amexon Development Corporation's Residences of 488 University Avenue, an ambitious intensification project that will add 37 new floors of condominium suites above an existing 18-storey office building.
Situated at the northwest corner of University and Dundas, the Core Architects-designed project requires extensive structural reinforcement work by engineers Sigmund Soudack & Associates to carry the additional loads of the new levels down to the bedrock below. The structural reinforcements, now in the process of being installed, will permit a tabletop-like transfer slab above the existing structure, shifting the load of the new levels through perimeter steel beams and cross bracing, across the face of the existing building, independent of its structure.
To prime the existing building for the structural reinforcement, the aging concrete grille facade of the office tower and its windows are currently being removed. This process is being undertaken using a custom-built hydraulic rig. New UrbanToronto Forum contributor bullitt_ride has posted that "the tool can be brought in level and attached to the fascia. Then for removal, the CG is adjusted for the weight of the load so that when the fascia is detached from the building, the load is balanced and remains level." Another part for the tool was built to handle corner sections of the grille.
This complex operation is being undertaken as business continues within the existing office building. Once complete, the structural steel reinforcements will become an important part of the development's exterior, tying together the project's architecture and engineering. The reinforced building's signature aesthetic element will be the cross-bracing, seen through new curtain wall windows with similar proportions to the windows of the old grille.
Residents of the 453 new suites atop the existing building will have access to 30,000 square feet of amenity space, appointed by interior design firm II BY IV Design Associates, including a gym, party room, roof deck, and a sheltered outdoor swimming pool.
