INNOVATION-May-June-2020

MIDDLE HARBOUR FILL SITE REMEDIATION Laurel Point Park in Victoria, BC, was previously the site of a paint factory until 1972 which left site soils with five different contamination classifications, ranging from commercial quality to heavy metals, hydrocarbons, and PCBs. Seventy thousand tons of contaminated soil were removed and disposed of at four separate disposal sites, and replaced with clean fill via barge. Two temporary berths were installed to provide access to load barges, saving 5,000 truck trips through

residential neighborhoods. Excavators fitted with RTK-GPS were used to selectively remove and survey lenses of contaminated material below the water table without visual confirmation. The project helped clean up the legacy of industrial activity in Victoria Harbour and will benefit the local community for years to come. Owner: Transport Canada. Contractor: A JV between JJM Construction Ltd. and QM Environmental. Consultants: SLR Consulting, Hemmera. Participants: Gary Hamata, P.Eng., Craig Peddie, P.Eng., Will Morris, P.Eng.

TRIDENT HYBRID FLOATING STRUCTURE Poseidon Ocean Systems delivered a new floating structure concept to Cermaq Canada’s site at Fortune Channel, in Clayoquot Sound. The goal of the project was to create a stronger, safer floating structure for industrial applications, such as aquaculture. The design incorporated steel framing and HDPE pipe elements to create a novel hybrid structure. The result is a structure with significantly improved stability, load capacity, and dynamic responses for a fraction of the cost of conventional options. The design achieved a secondary goal of providing areas to recess electrical conduit and other systems typical on an ocean farm. The result is a floating structure technology that is well suited to a wide variety of marine projects. It is dramatically stronger and more stable than conventional systems and can also be made from recycled materials, lessening the overall environmental impact. Participants: Tommy Yung, EIT, Jeff Fleming, EIT, Andrew Hartz, EIT, Nathan Hollenberg, EIT, Byron Sham, EIT.
