This expansion and redevelopment project was implemented on a site with a vertical drop of 3 meters from Boulevard Taschereau. This important difference in level has led to a significant constraint on the location of the enlargement and its geometry. Expansion of the emergency department of 38 stretchers was located on the ground floor, while the mechanical room, landing stages and delivery docks were located in the basement while being accessible from the ground floor of rue Saint-Charles. The position of these ambulant accesses, ambulances and delivery trucks was therefore dependent on this topography.
The expansion was designed to allow the construction of two additional floors to accommodate, among other things, the expansion of laboratories and the operating facility. A new mechanical leach will serve future floors only and will be able to support a heliport.
