After being vacant for some 30 years, the iconic inclined tower at Montreal’s Olympic Park has acquired a new lease on life as office space thanks to an ambitious $100 million refurbishment and renovation project. Carried out by a team that included construction manager Pomerleau, the project included rehabilitation of three facades of the tower, which inclines at a 45-degree angle.

As part of the work, the existing prefabricated concrete panels that covered a large section of the tower’s outer walls were removed and replaced with glass curtainwall. Construction got underway in July 2016.

The project team made extensive use of Building Information Modeling (BIM) technology in order to carry out what Mandalian described as a “technically challenging” project. A wealth of data was generated by the use of laser scanning technology to form “point clouds” enabling the creation of a comprehensive, high-resolution 3-D model of the existing structure. This helped the team precisely update drawings made in the 1970s.
