achieve LEED Silver. Beyond that, it com- plies with The Toronto Green Standard with such features as its 56,000 square feet of green roof. "There are actually five green roofs on the project and all irrigation – for both the landscape and the green roof – is from the three large stormwater cisterns," says Kees Govers, a technical sales manager with LiveRoof Ontario. Views from the southeast will reveal the building's largest green roof as its slope covers the practice pool. And beyond it is a large, aquamarine-blue corrugated steel wall that covers most of the eastern facade. The blue is a temporary wall and one that marks the complexity of this proj- ect: namely that it is a building that must change from pre-games mode, to games mode, and finally to a legacy mode. Many of the project's renderings express TPASC's final state, with an enormous sheltered area to the east that will serve as a covered drop-off whose roof is supported by a series of six V- columns. But that's the legacy state. For now, the space must be enclosed as it will be used to accommodate additional seating when TPASC is converted to games mode. The space between the V-columns and the existing seating in the com- petition pool area is essentially a 4,200-square-foot rectangle that will remain empty and separated from the interior of the building by a drywall bar- rier for mechanical reasons. "Having to condition that space would require additional air handling," says Coughlin of PCL Constructors. "Rather than adding that to the per- manent mechanical, TPASC will just use temporary units for cooling and air circulation when it's in games mode." Over the winter months, when there is the potential for snow load, the pre- games interior wall will support the 12, 250-foot-long trusses that span from the building's spine to the perimeter V-col- umns. Then in 2015, the drywall and its 10 support columns will be removed and temporary seating will be put into place to offer spectators a full, unob- structed 250-foot view of the space. W hen the games are complete, a new wall will be built to form the eastern perimeter wall adjacent to the passenger drop-off. Building the main competition pool area called for some irregular sequenc- ing. Rather than excavate the lower level and enclose the building, overhead work and the installation of the precast seat- ing (some in 40-foot-long sections) had to be done on a level ground surface. The competition pool and practice pools were assembled using an innova- tive stainless steel panel wall system, anchored to a concrete slab and covered in a PVC membrane. The dive pool was built as a standard concrete pool. Aquatic consultants Counsilman- Hunsaker, whose expertise was relied upon to build Atlanta's Olympic facili- ties, specified the Myrtha pool system. Its ceramic tile places the overflow gut- ter a bit further from the pool border to better absorb any disruption produced by the swimmer. This makes for a calmer pool, and one that is more conducive to setting world records. "We're trying to create an overall environment where athletes can do their best," explains Clusiau. Indeed, whether it is world-class competition, training the next great Olympian or just a Sunday afternoon swimming lesson, the Toronto Pan Am Sports Centre is a stage on which we can celebrate and nurture our national love of amateur sport. n Location University of Toronto Scarborough, Ontario agency ResponsibLe Infrastructure Ontario owneR City of Toronto / University of Toronto DeveLopeR (DbF team) PCL Aquatics Centre 2012 aRchitect NORR Limited constRuction PCL Constructors Canada stRuctuRaL consuLtant Halsall Associates Limited mechanicaL/eLectRicaL/ communications/secuRity consuLtant Smith + Andersen Consulting LanDscape aRchitect Janet Rosenberg + Associates gReen RooF consuLtant LiveRoof Ontario Inc. accessibiLity consuLtant SPH Planning & Consulting Ltd. aquatic consuLtant Counsilman-Hunsaker totaL aRea 360,000 square feet totaL vaLue oF DbF contRact $158 million ALL renderings courtesy high view communicAtions 86/ June 2014 Toronto Pan Am Sports Centre p.84-89Pan Am_Outlets.indd 86 14-06-03 10:25 AM
