Completed in 2012, the expansion of the Rotman School of Management more than doubled the size of the University of Toronto’s post-graduate management school. The new 15,000 m2 addition is fully integrated with the existing Rotman facility by links at multiple levels, including a grand new atrium shared between the two buildings.
The atrium’s bold feature staircase, painted charcoal grey with hot pink accents, features riser sections double-cantilevered off the floor structure. Solid steel plate handrails on both sides contribute to the staircase’s bold architectural presence. Most of the building uses architecturally exposed concrete, including polished “Retroplate” concrete floors in most public spaces.
The expansion also includes seven auditorium-style classrooms with tiered seating. A 600 m2 “Event Box” that hosts lectures, conferences, and special events features floor-to-ceiling two-storey windows overlooking St. George Street. The building integrates an existing restored heritage structure that now houses Rotman’s PhD program.
Challenge: Erecting the heavy staircase structure and minimizing its deflection and vibration concerned the project team at the outset of this development.
Solution: The team used monorails affixed to the structure above to erect massive stair sections. Vertical handrail plates stiffen the stair structure to minimize deflection and vibration of the stair.
