wasn't a problem," Brown says, " but the challenge was logistics- getting it fabricated, into Calgary and onto the site and onto the building in a timely manner. Because we have an urban site, there's not a lot of room for storage." The Bow will not have a concrete core like most similar tower structures; as a result, temporary steel supports have been welded onto the building frame. Those structures will be cut out once the concrete poured for floors is set. Some steel pieces weigh more than 45 metric tons and require multiple cranes to be lifted into place, Brown adds. " The sheer logistics of the site is something that we spend a great deal of time on every day." Some 500 workers are currently on the site, a number that will spike to nearly 1,500 when construction activity peaks. Getting talented labor to work on the project has not been a problem, even though the city has been going through a building boom for the past several years as the local economy surged, thanks in large part to work being done on the region's oil fields. " We have the shiniest building and a project that will be a legacy, and people want to work on projects like that," says Brown. When completed, The Bow will be the highest tower starting with the 58- story tower that is built over a two-block underground parking garage with room for 1,200 cars. A second, smaller building is also in the design, and a boutique hotel is envisioned for the site. Steel is now being erected on the tower, with major structural work expected to be done by mid- 2010, with EnCana staff starting to move in by mid- 2011. Because of the design of the structure, the project required a wide range of steel pieces. " Sourcing Matthews Development / Ledcor: The Bow DECEMBER 09 www. bus- ex. com 97 "" It will be more than just a building in this part of the city. It will be a new landmark and a new symbol of the city's arrival as a major economic player. It really raises the bar on office space design in North America as a whole"
