It’s fast becoming an iconic landmark of Calgary’s skyline and a time lapse video of the construction of The Bow is showcasing just how the massive structure went from nothing to the tallest building in western Canada.
It’s a short video shot entirely on a cell phone and, thanks to time lapse shots, depicts every step of the construction process that ended with the completion of the 236-metre structure, occupied by energy giant Cenovus.
The tower, which uses the curvature of a bow as its architectural signature, has 58 floors – two for retail, three for gardens and 53 for office space. It also has 1,7 million sq ft of office space, 900,000 sq ft of glass and a foot print of 190,000 sq ft.

The tower is also one of tallest buildings in Canada to use a responsive and efficient under-floor air delivery system.
The southwest-facing orientation of the building allows for the majority of the offices to have windows, which helps the building make use of sunlight and consume less energy for cooling and heating.
Construction for the environmentally-conscious Bow tower, named after the Bow River and the building's shape, began in 2007 and cost $1.4 billion.
Employees with Cenovus, the energy giant that will occupy half of the building, started moving into the tower mid-August in 2012. Encana employees will occupy the other half of the building.
The tower also has six floors of underground parking with 1390 stalls for cars and 420 for bicycles.
