Primary civil consultant Associated Engineering worked with developer and manager Ivanhoé Cambridge to develop the 75-hectare greenfield site. The project involved planning, design, and construction of 32 lane-kilometres of municipal roads and highways; a 6,000-stall parking lot; 3.8 kilometres of water mains; 5.5 kilometres of sanitary force mains; 1.4 kilometres of storm sewers; 25 culverts; 2 drainage overshot gates; 1 drainage pump station upgrade; 1 pressure reducing–valve station; and 3 sanitary lift stations. Storm water runoff is directed into rain gardens onsite and vegetated bioswales offsite, and is treated in oil/water separators before discharge. Sustainable design features resulted in a net increase in the quality and area of natural habitat.
RJC was the structural engineer for the Tsawwassen Mills shopping centre. Chris will discuss the silty ground and the challenges for construction, (geotechnical engineering for the project was by Levelton, now WSP Canada). Vibro-replacement stone columns were installed to densify the ground and reduce seismic soil liquefaction potential.
The structural system of the building is comprised of steel moment-resisting frame modules. The feature court spaces of the centre are dramatic heavy timber construction, with timber cable supported beams spanning spaces of up to 126 feet.
The project success was a result of the passionate team effort with the Owner Ivanhoe Cambridge and the Architectural design teams, Ledcor, and the heavy timber contractor, Macdonald & Lawrence. RJC submitted the project to the 2017 BC WoodWorks! Design awards, and Tsawwassen Mills won the BC Commercial Wood Design of the Year.
Shaun started his career as a Civil Engineering Technologist, working for the Ministry of Forests and Lands in Salmon Arm and then the Ministry of Transportation and Infrastructure in Williams Lake before moving to the lower mainland to continue his education. After completing his Masters of Applied Science in Civil Engineering at UBC in 2001, Shaun joined Associated Engineering as a designer in their Highways Group. Shaun has worked on many interesting and challenging Highway design projects over the years, the largest being the Port Mann/Highway 1 Project.
Since 2005 Shaun has been a member of the Transportation Association of Canada’s (TAC) Geometric Design Standing Committee (GDSC) becoming Chair of the committee in 2018. Besides highway work, Shaun developed and taught advanced CAiCE design training courses for the Ministry of Transportation and Infrastructure and has prepared Disaster Financial Assistance Arrangements (DFAA) Engineering reports for the Province. Looking for a new challenge, a shorter commute, and the opportunity to take part in a sustainable project in his community, Shaun assumed the Project Manager role in 2014 for the civil design and construction services related to the TFN commercial developments. Although extremely challenging, Shaun states that this project was definitely a highlight of his career so far, and like proud parents showing off their children, he takes every opportunity to share his experience on the Tsawwassen Mills project with all those who will listen.
For his past 10 years as a member of the structural team of RJC Engineers, Chris Jacques has focused on the design of shopping centres, downtown office buildings, and residential buildings. Chris also acts as the treasurer of the ‘Structural Engineer’s Association of BC Certificate Program’, which offers a suite of courses for practising engineers in BC and internationally. Chris is the coordinator and primary instructor for SEABC’s ‘Seismic Design of Steel Structures’ course. Chris Jacques is proud to serve as the Structural Engineer of Record for the Tsawwassen Mills centre.
