2015 PROJECT HIGHLIGHTS

Yale Hotel Built in 1889 as a bunk house for single male Canadian Pacific Railway workers, the Yale Hotel is a three-storey, Second Empire-style building distinguished by its bellcast mansard roof, gabled dormer windows, and round arched windows. It later became one of the premier blues clubs in North America. As part of the rezoning of the adjacent Rolston development, the heritage building received safety, structural, and seismic upgrading, tying in the vertical and horizontal wood frame elements of the building. The brick façade is completely re-attached and restored, with additional windows facing the street. The current dropped ceiling panels were removed, restoring the bar area to its full 14-foot height, with special drywall to dampen sound travelling to rooms upstairs. Other improvements included a new bar, kitchen, dressing rooms, and larger wooden dance floor. The cherished heritage building is now restored to its original charm. Owners: Rize Alliance Properties, IBI/HB Architects. Structural engineers: Glotman Simpson Consulting Engineers.

NO x Reduction Project The Metro Vancouver Waste-to-Energy Facility, located in Burnaby, plays an essential role in the region’s solid waste management system. In 2011, the Ministry of Environment set out new guidelines for nitrogen oxides (NO x ) emissions from waste-to-energy facilities, lowering the limit from 350 to 190 mg/Rm 3 . In response to the new guidelines, Metro Vancouver initiated the NO x Reduction Project that reduces NO x emissions through implementation of a low NO x combustion control process in combination with upgrading the existing selective non-catalytic reduction (SNCR) system. Following project start-up in late 2014, NO x emission levels were reduced to approximately 134 mg/Rm 3 , more than 52% lower than the 2013 operating average of 281 mg/Rm 3 and 30% lower than the guideline limit of 190 mg/Rm 3 . Owner: Metro Vancouver. Project management: Chris Allan, P.Eng. (Metro Vancouver); Leo Lakowski, P.Eng. (LR Power Solutions). Design: Steve Noble, P.Eng.; Terry Good, P.Eng. (Allnorth)

Stewart World Port Terminal Stewart World Port is a multipurpose, deep water port facility that opened in June 2015. Located two kilometers south of the town of Stewart, the port serves the resource industries in BC, Alberta and the Yukon, exporting mineral concentrates, coal and forestry products, and importing breakbulk cargo. CWA carried out the detailed engineering and procurement services for the wharf, berthing dolphins, approach trestle and shiploader rail girders. Using an innovative steel pile cap design and a comprehensive procurement strategy, the construction sequencing was optimized and significant capital cost savings realized. As the wharf is located in very deep waters, environmental impact was minimized as there was no need to dredge the existing mudline. Owner: Stewart World Port. Consultants: CWA Engineers (Raymond Chu, P.Eng.; Mark Malecek, P.Eng.; Kevin Wong, P.Eng.; Gordon Chao, P.Eng.; Manny Wang, P.Eng.; Hamidreza Baktash, P.Eng.; Susan Chen; Harvey Sonntag; John Majoor; Man-Hin Lo, EIT; Thomas Duke, EIT), GeoNorth Engineering.
