$ 500M real estate development project to make downtown Longueuil a TOD project. The project is made up of two 40-storey towers resting on an impressive steel structure podium above the Longueuil – Université-de-Sherbrooke subway station.

This podium allows in particular to overhang the infrastructures of the tunnels and platforms of the metro station. In addition to providing access to STM users, it will house many commercial spaces as well as a food court.


  • Transfer of residential structural layouts in order to avoid columns in the STM transit spaces.
  • Accommodation of the needs, requirements and priorities of the City of Longueuil, the STM and the developer.
  • Investigation, location and management of a main sewer line crossing the site of the future building, without precise existing plans or access to the interior of the infrastructure.
  • Integration of spans of up to 54 m in the food court and 18 m under the two residential towers.


  • Integration of transfer beams in passive reinforcement, with a flexible design in order to compensate for the imprecision of the existing sewer pipe at the time of the structural design.
  • Complex geotechnical and geomechanical studies to quantify the effect of laying new foundations 500 mm from existing STM installations.
  • Elegant and ingenious tree-shaped structures to manage long spans in the food court.
