City Centre Medical Building Located across from Surrey Memorial Hospital, City Centre 1 is a 12-storey medical office tower housing the Health Tech Connex innovation centre, specialist medical practitioners, doctors’ offices, physiotherapy clinics, and the headquarters of the Lark Group. The project is pursuing LEED ® Gold certification, and includes features to reduce consumption of water and energy, maximize occupant health and comfort, and improve the local community. Strategies include use of green roofs, combination rainwater harvesting/storm detention system, compressor-driven heat recovery DOAS ventilation, and facilities encouraging walking, cycling and use of public transportation within the community. The building has provisions for future connection to Surrey City Energy’s district heating utility, providing the opportunity to benefit from Surrey’s plans to imple- ment low-carbon heating sources. Building Information Modelling (BIM) software was used by all disciplines as well as the construction team. Owner: Lark Group. Architect: Wensley Architecture. Mechanical: Williams Engineering (Mike Dixon, P.Eng.). Structural: Bogdonov Pao & Associates (Walter Janzen, P.Eng.). Electrical: Colwin Electrical Group.

International Military C-130K Aircraft Cascade Aerospace recently delivered the first of two

international military C-130K aircraft to the Mexican Air Force, after executing an extensive Maintenance and Modernization program at its base in Abbotsford, BC. Cascade’s engineering teams designed a complete upgrade to the cockpit avionics system, including integration of the advanced digital Rockwell Collins Flight 2 avionics suite to meet 21 st century navigation and communication standards, as well as digital fuel quantity indication and engine instrument display systems.This delivery represents a significant milestone for BC’s aerospace industry and a comprehensive solution for the Mexican Government at a fraction of the cost of a new aircraft.

Port Mann Bridge Deconstruction Upon replacement in 2012, the 50-year old Port Mann Bridge was commissioned for controlled deconstruction to prevent the diffusion of hazardous substances to the environment. This required a highly technical and piecewise removal where the original bridge was transformed from a tied-arch to a cantilever structure and dismantled through reversing the original construction scheme using a temporary cable-stayed system. The major challenge was to maintain the stability of the extremely vulnerable partial structure under construction loads and dynamic winds as the removal progressed. Access restrictions from the since expanded rail yard under the south side-span required careful sequencing and strengthening measures. Containment procedures were employed at superstructure cutting locations (starting from the centre) as components were removed for recycling. Owner: Ministry of Transportation and Infrastructure. Contractor: Kiewit- Flatiron. Prime consultant’s APEGBC members: David Jeakle, P.Eng.; Morgan Trowland, P.Eng.; Chad Amiel, P.Eng.; Ben Ticknor, EIT (Infinity Engineering – a McElhanney Company).
