As a leader in occupational health and safety in Quebec, the Commission des normes, de l'équité, de la santé et de la sécurité au travail (CNESST) designed its new headquarters to reflect this commitment to employee well-being. The building houses 1,850 workstations and offers a wide variety of collaborative workspaces spread over 8 floors. As part of the WELL Certification process, the headquarters was designed with an emphasis on the aesthetics, functionality and comfort of the spaces, with the aim of creating a welcoming environment for all employees, so that they can make a greater contribution to the health and safety of all Quebec workers.

The CNESST gave BIM One a mandate to support the implementation and deployment of BIM within its organization. Within the framework of this project, carried out as an integrated design process (IDP) between the Société québécoise des infrastructures (SQI), the CNESST and EBC, BIM One played a key role as lead BIM manager during the design phase, within the Groupe OS consortium.

The new CNESST headquarters won the Cecobois Award in the Architecture category, highlighting its remarkable design and innovative use of wood as the main material. This recognition testifies to the excellence of this project and its positive impact on the environment and the people who work there.
