The Bow

Recognized for innovative solutions, The Bow project was awarded numerous design and construction awards

The mixed-use development will be western Canada’s tallest building and Calgary’s first steel skyscraper. The Bow project was awarded the Canadian Institute of Steel Construction Award of Excellence, the American Concrete Institute Award of Excellence, and the Consulting Engineers of Alberta Showcase Award, in the category of Studies, Software and Special Services.

The Bow is a crescent-shaped, steel-framed tower containing 58 floors of office and retail space. Its curved design reduces the impact of wind, while three sky gardens allow for greenspace for employees. The project cost $1.4 billion to construct.


  • precise geodetic control
  • building deformation monitoring
  • plumbing of structural steel columns
  • layout and as-built of key building elements
  • detailed topographic and legal survey
    • Design, establishment, and maintenance of a suitable control network satisfied stringent layout requirements and allowed a demanding project schedule to stay on-course
    • Employment of sophisticated, state-of-the-art survey technologies such as precise digital inclination sensors that were key to the success of a project this dynamic, complex, and difficult
    • Use of leading-edge methodologies such as monitoring of building dynamics and correction of GPS-derived positions for building tilt, both in real time, are unprecedented in a Canadian skyscraper project
  • The office tower was named to the Most Spectacular Buildings list by Emporis, a global design and construction authority, and secured first place in Azure Magazine’s top projects of 2012.
