Cité Desjardins de la Coopération

Office Tower Construction

There was no shortage of challenges with this Desjardins Financial Security project. Despite everything, we successfully completed the construction of Cité Desjardins de la Coopération and all project-related work.

Our initial mandate was to build a 15-storey tower, including underground parking and common areas. In addition, there was extensive project-related work: 

• Realigning Commandeurs Street.
• Building a tunnel and two covered pedestrian walkways to connect the new tower to the rest of the Cité complex.
• Building a public square.
• Redeveloping the parking lots.
• Creating two retention ponds.
• Demolishing two existing buildings.

Since sustainable development is central to every Pomerleau project, the stone cladding of the demolished buildings was recycled and integrated into the site's landscaping.

We also installed green roofs and the world's tallest indoor green wall, measuring 65 metres in height. That's in addition to a variable airflow ventilation system with CO² sensors that modulates the supply of fresh air based on the occupation of each space and a geothermal system that meets nearly 17% of the building's heating and cooling needs.

Pomerleau also built sophisticated control systems that automatically adjust the direction of the building's solar shades to the intensity and angle of the sun, modulate its energy-efficient lighting based on natural light and automatically activate motorized shutters to provide natural ventilation to the tower's green wall.

Ensuring Safety and Traffic Flow

We ensured the safety and traffic flow of 5,500 employees and visitors throughout the project. We also did some blasting near occupied buildings and had to make the new building safe and functional before the work was completed.

Demolishing the Old Building

During the demolition, we relied on our in-depth knowledge of historical construction techniques to retrieve materials without damaging them.

Starting Work Before Obtaining the Final Plans

We demonstrated our flexibility by starting work before obtaining the final plans. Many modifications were, in fact, made to the original design during the project.

Limited Parking Space

We built a temporary parking lot with shuttle service and sidewalks to make up for the lack of parking spaces during construction.

Realigning a Street

In collaboration with the City of Lévis, we realigned Commandeurs Street.
