Quebec National Assembly Building Expansion

Redevelopment and Expansion

We were awarded the mandate to expand the Quebec National Assembly building to ensure that it meets current building codes and standards.

More specifically, we were responsible for the following components:

• Adapting the building to the multiple functions of the National Assembly.
• Increasing security, accessibility and space.
• Adapting the building to accommodate more than 100,000 visitors per year.
• Increasing the number of parliamentary committee rooms.
• Incorporating the concepts of democracy and public involvement into the project.
• Implementing sustainable building measures.

We redesigned the existing space and expanded the building by 5,109 m². This expansion was divided into three segments:

Courtyard 

The first segment of the project consisted of underground construction at the Parliament Building, merging its technical and support spaces.

Visitor Centre

The new visitor pavilion of the National Assembly involved new underground construction in the Parliament Building’s esplanade. This construction included these components:

• A shop.
• A checkroom.
• An agora.
• A multi-purpose room.
• Two new parliamentary committee rooms.
• A tunnel to the courtyard.

Redevelopment and Gatehouses

The last segment of the project consisted of redeveloping certain parts of the Parliament and building two new security booths.

High-Traffic Site

We performed our work in an urban area which is also the heart of downtown Quebec City’s tourist zone.

Continuous Use

During many months of work, the building remained occupied by members of the National Assembly.

Preserving a Historic Building

We carried out our work, protecting this heritage building—built in the late 1800s—every step of the way.
