Encana's Bow building about to dwarf Calgary Tower

It's hard to miss on the Calgary skyline.

The massive metal frame of the Encana Bow building is shooting up and is now at 36 stories, nearly as tall as the Calgary Tower.

A spokesman for the construction company tells 660News when it's completed, it will stand 58 stories high and span two city blocks.

The finished product will house all 3,300 of Encana's employees who are now scattered in five different locations.

The bricks from the neighbouring historic York Hotel have also been saved and will be incorporated into the new building.

Construction began on the new Encana headquarters three years ago and it's expected to open in early 2012.

The Bow is located on 6th Avenue between Centre Street and 1st Street S.E. and will be the largest Canadian skyscraper outside of Toronto.
