3 min.

How did the construction of Collège Sainte-Anne in Dorval, a carbon-neutral project designed by renowkned Atelier Pierre Thibault and celebrated with international awards, manage to cost two to three times less than current public-sector standards? One word: collaboration.

As our client aptly puts it, "We’re not magicians." What we achieved in this project can—and should—be replicated across construction projects nationwide. Collaboration and the early involvement of all stakeholders during the design phase are vital to transforming any vision into a true success story.

The School of the Future, Built Today


In 2019, when Ugo Cavenaghi, President and CEO of Collège Sainte-Anne, presented his vision for a new high school on the grounds of the existing primary school in Dorval, it instantly captured our attention. His desire to think differently, step outside the box, and reimagine learning environments resonated deeply with us.

The goal? A creative and collaborative learning space unlike any other. Open classrooms, living walls, expansive two-story bleachers at the heart of the buildings, and an abundance of natural light were just a few features of this groundbreaking design. Conceptualized by Atelier Pierre Thibault and Architecture49, the project was not only innovative but also environmentally conscious, aiming to become one of Canada’s first carbon-neutral schools.

Collaboration: The Foundation of Success

What set this project apart was Mr. Cavenaghi’s decision to involve its general contractor from the very beginning. By engaging JCB Construction Canada early in the process, we were able to offer construction management services and bring our expertise to the table during the critical design and preparation phases.

This early collaboration allowed us to work closely with architects, engineers, and stakeholders to identify opportunities for cost and time savings before construction began. By leveraging our construction management expertise and implementing Building Information Modeling (BIM), we were able to detect and resolve potential conflicts between structural, mechanical, and electrical systems early in the process. This proactive approach minimized costly mid-project changes and streamlined the entire construction timeline.

From day one, collaboration was the driving force behind the project’s success. Our integrated approach ensured that all parties worked toward a shared vision, balancing budget, sustainability, and functionality without compromise.

Adapting to Challenges: A Fire That Changed Everything

As the high school’s design was being finalized, a devastating fire struck the historic primary school building in April 2020. The 19th-century structure, once home to North America’s first golf club, the Royal Montreal Golf Club, was severely damaged and contaminated with asbestos, making restoration impossible.

Rather than be discouraged, Collège Sainte-Anne doubled down on its ambitions. Not only would the high school project move forward, but the fire-damaged primary school would also be rebuilt, expanded, and renovated—all on the same campus.

This new mandate transformed the Dorval campus into a dual project: rebuilding the primary school and constructing the innovative new high school. Despite the expanded scope, the project maintained its ambitious sustainability goals and timeline.

Innovative Design for a Modern Learning Experience

Inspired by Europe’s most forward-thinking schools, the architectural team created a campus that fosters creativity and collaboration. The design features open classrooms, multi-use spaces, and expansive areas for gathering and learning. The gymnasium, library, cafeteria, and outdoor pavilions were all designed to maximize natural light and create an inspiring learning environment.

Kilometres of Radiant Flooring

In the pursuit of building a state-of-the-art carbon-neutral facility, the construction of Collège Sainte-Anne’s new primary and secondary schools incorporated a cutting-edge radiant piping system. To achieve this, dozens of kilometers of high-performance piping were embedded within the concrete floors, creating an efficient and sustainable solution for heating and cooling the premises.

This eco-friendly and energy-efficient hot and cold water system ensures even heat distribution throughout the buildings, maximizing comfort for students and staff. Unlike traditional systems, it eliminates draughts and temperature fluctuations, providing a stable and pleasant indoor climate year-round.

One of the standout features of this radiant system is its complete silence and unobtrusive design. By taking up no usable space, it seamlessly integrates into the schools’ infrastructure while significantly lowering energy consumption. This innovative approach not only supports the facility’s carbon-neutral goals but also reduces heating and air-conditioning costs, making it a financially and environmentally responsible choice.

The implementation of this advanced heating and cooling technology highlights Collège Sainte-Anne’s commitment to sustainability, comfort, and innovation, setting a new benchmark for educational facilities across Canada.

Tons of new windows

The architectural vision for Collège Sainte-Anne’s campus included highly glazed facades, maximizing natural light and harnessing passive heating to enhance energy efficiency. To bring this concept to life, the design team selected stunning custom-made windows crafted from mahogany and oak. Some of these exceptional windows measured up to an impressive 7.5 meters by 2.5 meters and weighed nearly 3,000 pounds each.

The installation of these oversized windows presented significant technical challenges. Delivered in a single piece and pre-glazed, these monumental windows—recognized as the largest ever manufactured by the supplier—were unable to support their own weight during handling and installation. Additionally, the unique geometry of the building ruled out the use of a crane, requiring an innovative approach to overcome these logistical hurdles.

JCB Construction Canada quickly rose to the occasion, leveraging their expertise and collaborative spirit. Partnering with fabricated metal specialists, the team designed and engineered a customized solution, including a specialized fork and tailored transfer equipment. This innovation enabled the safe unloading, transportation, and installation of the massive windows.

The process involved using multi-directional ball transfer tables, a modified fork, dedicated straps, and the combined strength of six skilled site workers. Through careful planning and precise execution, the team successfully installed these unique windows, seamlessly integrating them into the building’s structure as envisioned by the designers.
