INNOVATION May-June 2014

Award of Merit Surrey Memorial Hospital Acute Care Tower

Consultant: MMM Group Ltd. and Bush, Bohlman & Partners | Client: EllisDon Corporation This project required both a redevelopment and expansion to meet the requirements of one of Canada’s fastest growing communities. It used durable natural materials that emit low amounts of volatile organic compounds. The team created a high-efficiency mechanical and electrical system and designed state-of-the-art energy efficient technologies, completing a sustainability design approach for environmental, economic and social sustainability to attain LEED Gold status. Award of Merit TRIUMF Advanced Rare Isotope Laboratory (ARIEL) Consultant: Stantec Consulting Ltd.; Bush, Bohlman & Partners; and AES Applied Engineering Solutions | Client: TRIUMF This laboratory was a highly specialized installation using leading- edge technology and features a superconducting electron accelerator, electron linear accelerator, proton beam line, high-power target stations and a front-end isotope separator. The laboratory includes a highly specialized nuclear ventilation system with “active” and “non- active” cooling systems along with the room pressurization systems. missions, Metro Vancouver engaged Kerr Wood Leidal Associates to develop the Heat-Seeking Sewer Model to calculate the sewage flow rate and associated sewage temperature at nodes within the sanitary sewer network in order to recover this energy to heat buildings. The first of its kind, the model results showed that there is up to 100 MW of recoverable heat available across the region, enough to heat about 650 – 1,000 high-rise buildings. Award of Merit Modelling of Potential Tsunami Inundation Limits and Run-Up Consultant: AECOM | Client: Capital Regional District Vancouver Island’s Capital Regional District recognized a need to better understand regional tsunami risk. In partnership with Dr. K.F. Cheung, AECOM analyzed a magnitude 9.0 megathrust earthquake using a state-of-the-art non-hydrostatic computer model, NEOWAVE, to determine tsunami impacts from inundation and run-up. The results provide valuable tools to assist in the development of emergency preparation, planning, evacuation and awareness programs and communicate warning signs. jet grout columns to replace existing soils and stabilize and strengthen the abutment soils underneath the concrete dam; construction of a plastic concrete cut-off wall upstream and downstream of the dam using trenchcutter technology; and installation of a unique flexible membrane connecting the cut-off wall with the concrete dam. Award of Merit Inuvik LNG for Community Electricity – Power for the People Consultant: Associated Engineering | Client: NT Energy Associated Engineering led a team that designed and provided construction services for new liquefied natural gas (LNG) storage and vapourization equipment, due to its lower cost and environmental benefits, when a natural gas well ran dry in Inuvik. As the first installation of its kind in Northern Canada, innovations included a unique containment system using local materials; low temperature equipment with appropriate weather protection; and foundation slabs to preserve the permafrost layer.

BUILDINGS Award of Excellence Jasper Place Library Consultant: Fast + Epp | Client: Hughes Condon Marler Architects

This striking, free-form clear span civic facility consists of a concrete roof slab that cascades into concrete columns at two sides and is supported by light steel columns at the front and back. This design concept is not reliant on additional shear walls or bracing for lateral stability, with the result being a structure that appears to float under maximum daylight penetration. Detrimental effects of thermal bridging due to cold Alberta climate are avoided by including thermal isolators.

SOFT ENGINEERING Award of Excellence Heat-Seeking Sewer Model Consultant: Kerr Wood Leidal Associates | Client: Metro Vancouver To displace natural gas consumption and reduce greenhouse gas

NATURAL RESOURCE, ENERGY AND INDUSTRY Award of Excellence Ruskin Dam – Right Abutment Seepage Control Upgrade Consultant: Golder Construction Inc. | Client: BC Hydro and Power Authority The installation of a seepage cut-off system at the Ruskin Damwas undertaken to address seepage issues and seismic performance on the dam’s right abutment. Work included the installation of overlapping
