Revamping a visionary structure
GMP Architekten is part of a significant renovation at Montreal’s Olympic Stadium, tackling the longstanding issues with its roof. This ambitious project replaces the problematic membrane roof with a durable steel deck, ensuring protection from the infamous falling icicles.
A historical centerpiece
Constructed for the 1976 Summer Olympics, the stadium is a crucial part of Montreal’s Olympic Park. The original site, designed by French architect Roger Taillibert, included features like a velodrome, now the Montreal Biodome.
GMP Architekten has teamed up with Schlaich Bergermann & Partner, WSP Global, and Transsolar to redesign the stadium’s roof. The project aims to preserve its iconic design while addressing past challenges.
The quest for stability
The original Kevlar roof, retracted by cables from the stadium’s tower, presented continual difficulties. Because of this complexity, along with costs, union strikes and more, the roof was never fully operational. Even local authorities once considered demolishing it due to its issues.
GMP Architekten director Martin Glass notes the initial construction’s ambitious nature outpaced the 1970s Canadian construction capabilities.
A modern solution
The team has devised a new approach, integrating a non-retractable steel cap with skylights. By suspending up to 90 percent of the new roof’s load via the original tower’s 26 cables, they ensure structural support.
Martin Glass explains that replacing the heavier concrete ring with a lightweight steel and aluminium framework affords the needed flexibility.
Innovative techniques
Currently, around 35 percent of the inner roof is complete, built on the stadium’s floor. Huge cranes will elevate this element into place. Once positioned, skylights will seal the space between the structural components.
“Once the roof is fully finalised on the floor, we will have these big mega cranes that will push the whole roof up to its correct height of around 50 to 60 metres,” Glass describes. The steel covering will solve the issues caused by the previous membrane.
Year-round functionality
Harsh winters once forced the stadium to close. The previous roof, plagued by punctures from icicles, proved unsustainable. The new steel deck with shock-absorbing cladding promises durability in cold weather.
“That will allow the client to use the stadium all year long without disruptions,” Glass states. This adjustment aims to safeguard its operation against financial setbacks linked to seasonal closures.
Light and life
The new design includes an illuminated underside with skylights, welcoming natural light inside. Glass emphasizes the benefits: “With the glazed ring we’re adding, the stadium will experience daylight, enhancing its usability for spectators and events.”
Improvements were announced in 2020, and include modernising the interior and tackling features like the existing cable car and glass observation deck.
“It will be a fresh chapter for the stadium, making it feel connected to its surroundings like never before,” Glass adds. These efforts stay true to the original design’s boldness and organic form, whilst addressing past concerns.

Preserving architectural integrity
The project remains faithful to its visionary roots. “This building is already so strong, with its organic quality and sculptural expressiveness,” Glass says. Their goal: to enhance without overshadowing its historic architecture.
