J UNE 2017 | 55 PHOTOGRAPHY COURTESY PCL CONSTRUCTORS WESTCOAST INC. The Exchange could be signed with the owner of a neighbouring building, meaning all construction had to be confined within The Exchange's property line. "So swing cranes and other equipment had to be specifically sized to work in tight confines," says Nadja Gehriger. It also meant that PCL Constructors Westcoast Inc. had to perform elaborate shoring and build the tower's foundations from the top down. Support of the tower over the stock exchange building involved punching holes through all 11 levels of the original building for four of the 10 structural columns. "Establishing the foundations took two years," notes Gehriger. "Needless to say, going up with the new tower was a lot quicker." Gehriger goes on to point out that one way for the project to meet LEED Platinum standards "was to import radiant heating and cooling and other HVAC systems from Europe. The two buildings incorporate a great deal of European technology." Wolf Schenke, principal of MCW Consultants Ltd., adds, "A task ambient lighting system of 30-foot candles was designed in order to provide useful and comfortable ambient lighting, and a vertical busduct system enables each floor to be loaded according to need." Schenke credits the Gehriger family for being "extremely forward thinking. For example, back in 2012 Franz insisted on all LED lighting and was willing to pay the upcharge; fortunately this technology rapidly became more affordable and the selection way more expansive in the intervening years." The Exchange offered unique landscaping opportunities. PWL Partnership Landscape Architects Inc. founding principal Margot Long and her team provided streetscape elements including the reinsertion of glass blocks along the edges of the stock exchange building to acknowledge its heritage (the old trading area was located in the basement); they also created a rock garden and seating area for the tower's amenities space as well as an expansive green roof for the top of the stock exchange. While final completion of The Exchange is scheduled for later this year, Nadja Gehriger is already impressed by the realization of her father's dream. "Honestly, the final result is even better than the renderings, which were spectacular," she says. "It's an honour to preserve an important part of Vancouver's heritage and make it part of the city's future." A LOCATION 475 Howe Street, Vancouver, B.C.
