This $60.5M project aimed at improving the infrastructure of the Parliament building housing the Quebec National Assembly. Works consisted of expanding the building for the first time in 100 years, in order to meet current needs in terms of parliamentary activities and accessibility for citizens.

The primary objectives for the projects were to:

  • Facilitate and accelerate visitors’ entry, while strengthening security, through the construction of a 3,800 m² underground building
  • Offer facilities to accommodate the increasing number of parliamentary committees and open sittings, through the construction of a new building in the inner courtyard

Design was carried out in 3D with Revit, as part of a BIM process. The project aims for a LEED Silver certification.

The creativity and precision of execution demonstrated in this project allowed it to win the “Buildings – Mechanical and Electrical” category for the Grands prix du génie-conseil québécois 2020 awards from the Association des firmes de genie-conseil.
