The Manulife Centre, located in downtown Toronto and along the stretch of Bloor Street West referred to as the Mink Mile and considered the city’s premier luxury retail destination, is a mixed-use luxury residential, retail and commercial space undergoing an extensive revitalization and expansion to transform the retail space in the ground and second floor podium.
The Manulife Centre consists of a 51-storey luxury residential tower at 44 Charles Street, a shorter tower at 55 Bloor Street West and connected by a retail complex on the concourse level, main floor and 2nd floor. The expansion involves extending the retail space from the existing building façade at the ground and 2nd levels to the existing site’s perimeter while the revitalization includes renovations to the entrance and exits for the building and alignment of the retail space floor levels with existing street levels. The new construction will be built on the existing below grade structure with the column loads being transferred to existing vertical structures with steel beams. The second floor and roof levels of the new build will be connected into the second and third floors of the existing structure.
Challenge: Working extensively with an existing structure originally built in the 1970’s and having had significant renovations and additions over the years.
Solution: The client provided a set of original construction drawings which included numerous packages of the various revisions that had been made in the past. From the outset, our BIM team carefully studied the existing information and developed a REVIT model that included the areas that were to be altered or demolished. Using this base information, the understanding of interfaces between old and proposed was simplified as sections and elevations could be easily cut through any part of the building.
