Splatsin Community Centre Portrays Traditional Form With an architectural design vision inspired by the traditional aboriginal Kekuli earthen structures of the past, the Splatsin Community Centre portrays traditional form following the age-old function of a community gathering place. The 33,000-square-foot circular building houses a large open space for recreation and community gatherings, surrounded by a running track and spaces for commercial retail units, classrooms, and boardrooms. The structure’s 36-metre clear-span roof-framing system, comprised of custom steel trusses, is supported by a tension-compression ring. An outer ring of reinforced concrete floors and walls supports a perimeter mezzanine level. The entryway features structural log columns and beams with cross-laminated timber decking. Consultant: Stantec Grandview Heights Aquatic Centre, Surrey, BC This iconic LEED Silver-targeted aquatic facility features a 10-lane competition pool with dive platform and spectator seating, a leisure pool, lazy river, water slide, sauna, hot pools, and a fitness centre. Using liquid chlorine, regenerative media filters, and ultraviolet reactors, AME Consulting Group Ltd. designed the pool system configuration to produce superior water quality while consuming less water, thereby reducing operating costs. Ultraviolet light destroys chloramines dissolved in the pool water, and chloramines in the air are exhausted from the pool gutter drain. High-level supply air washes the natatorium structure and windows. At low levels, it acts as displacement ventilation, providing effective make-up air for the pool’s gutter exhaust system. The structural design integrates air distribution. High-efficiency, heat-recovery chillers move heat recovered from the exhaust-air stream to areas requiring heat, and condensing boilers provide back-up heat.

World-Class Track and Field Facilities, Greater Vernon Athletics Park Design and construction administration was provided for a fully landscaped sport complex with a FIFA two-star synthetic-turf soccer/football field, sand-based natural grass field, internationally rated synthetic-surface, dual-colour running track with shot-put sectors, javelin, discus and hammer cage, high jump, and pole vault. The field house contains public washrooms, team change rooms, and a classroom. Bleachers sit 400.

A thick layer of in situ expansive clay and the proposed facilities’ tight footprint created challenges to achieving stringent tolerances that relate to differential movement on the finished track surface.The design called for the clays beneath the track and synthetic field to be replaced with non-frost-susceptible granular material. Where possible, the clay was re-used as fill beneath the turf field and within berms. Uncontrolled fill beneath existing high-pressure gas mains was another layout and design challenge.
