INNOVATION May-June 2018

REBUILDING A CREEK AFTER A DEBRIS FLOWAT A MINE Golder has been involved in rebuilding Hazeltine Creek since a debris flow caused significant physical impacts to the existing fish habitat. The project is part of ongoing fish habitat rehabilitation work at the Mount Polley Mine in central BC. A two-phase approach was used: the first phase was to construct an engineered channel foundation resistant to erosion, and the second phase was to re-establish instream and riparian habitat values. The photo is of a section of Hazeltine Creek constructed in 2017, part of the 2.3 kilometres of creek habitat constructed to date. An important part of the success of this field-fit, design-construct program was close teamwork between the professional engineer, professional biologist, and operational staff at the mine, as well as close collaboration with local First Nations and their scientific advisors and agency staff.

THREE-TOWER DEVELOPMENT NEAR AN AIRPORT The International Trade Centre and OPUS Hotel Versante is a dynamic new Richmond, BC, business hub that demands a high level of team coordination by construction managers Scott Construction Group. This three-tower, 215,000-square-foot development is composed of 12- and 14-storey office towers and the five-star luxury boutique OPUS Hotel Versante. The project faces logistical challenges due to its tight footprint and proximity to BC Hydro lines, a major highway to Vancouver International Airport, and a buried jet-fuel line. Airport proximity creates critical coordination requirements with authorities such as the BC Ministry of Transportation, Nav Canada, and YVR to ensure safety is maintained at all times.

Scott, P.Eng., Matt Gore, P.Eng., Emil Mihailescu, P.Eng. (AB), Owen Qazilbash, P.Eng. (AB), Michael Masinovsky, P.Eng. (AB) PARTNERSHIP BETWEEN EDUCATION AND INDUSTRY Austin Engineering Ltd., together with Selkirk College and FortisBC, won the 2017 Clean Energy BC “Operational Excellence” award. The award was given for their innovative solution to supporting the future operations of FortisBC’s “extreme consequence” Corra Linn Dam, as well as building opportunities for Selkirk students to work with industry. Austin Engineering provided access to its dedicated research and development lab to create 3-D– printed models of the dam, which FortisBC then used for future work planning, improved stakeholder engagement, evaluating cost-effective solutions, and developing improved environmental outcomes. Austin Engineering is also collaborating with UBC Okanagan to test the 3-D–printed and digitally fabricated gravity dams to determine potential damage during seismic events. This partnership bridges gaps between education and industry, and provides state-of-the-art solutions for a large hydropower company. Project owners: Austin Engineering Ltd.
