Rehabilitation of the existing building and new buildings


100 M$

The former Institut des sourds-muets de Montréal is a Beaux-Arts style building built in 1918 by the Clerics of Saint Viator. It has been renovated and refurbished with the aim of converting it into phase 1 of the residential complex called Le Castelnau. Phases 2 to 4 are new buildings.

In the existing building, seismic retrofitting was carried out using the concrete elevator walls as a load-bearing wall, and an additional floor was added. The structure of the new buildings is made of reinforced concrete.

For this project, NCK provided complete structural engineering consulting services.
