Phase 1 of the UBC Sauder School of Business revitalization project adds 50,000 SF to the existing 216,000 SF of the Henry Angus Building, providing a new facility for the Robert H. Lee Graduate School and a dedicated undergraduate centre. The new four storey building has classrooms on two levels, a library on one level, two lecture theatres on the top floor and a lecture hall in the basement. The LEED Silver equivalent building is concrete to grade and steel framing above grade, with chevron braces and composite beams.
The large lecture hall in the basement required that no columns block students’ line of sight. Glotman•Simpson utilized large post tensioned transfer beams, spanning 18.8 meters, on the ground floor to allow for no columns in the basement lecture hall space. These beams support the entire building structure above.
The new building had to be seismically separated from the existing adjacent buildings, which were used for gravity support along the east side and parts of the north and south sides. Glotman•Simpson provided horizontal slip connections at the building-to-building joints to allow the new building to move independently. The roof uses long span glulam beams to accommodate the curved sloping roof of the lecture theatres at the top level. Phase 1 of this project was completed in January 2010.
Phase 2 saw completion in September 2011, with existing classrooms upgraded and a new 600 square metre conference centre penthouse added to the top of the School’s existing administrative tower. A new learning commons was also introduced.
