The project of the 5505 Queen Mary Condominiums in Montreal is a construction of a new four-storey building in concrete with an underground parking lot.Public safety and neighboring buildings require precise and meticulous attention to avoid any damage that may occur during excavation, structural and exterior envelope works. Also, the quality of finishes (ceramic, wood flooring, kitchens, etc.) plays a key role in the success of this project.The work therefore requires coordination of all trade contractors, professionals and staff to be able to perform the work with efficiency and quality.The professionals who worked on this project were Atelier Ville Architecture Paysage (architecture and landscaping), Le Groupe Solroc (foundations and underpinning), Ingcon Consultants (structure), MLC (mechanical and electrical).
