Our team was awarded the mandate to find a strategy for preserving the Grand Théâtre de Québec, which officially opened in 1971. The deterioration of the building’s concrete structure and the corrosion of its concrete anchors led to a crumbling exterior wall, threatening the safety of the general public.
To preserve the building’s heritage value and ensure the safety of its users, we proposed a unique solution to the client, which consisted of designing and building a glass façade around the theatre, approximately 2 metres from the original concrete façade.
The space between the new glass wall and the existing cladding, which would remain dry and temperature controlled, would protect the building from further deterioration. This solution would also respect and protect the unique look and character of the architect's original design.
Preserving historic elements
We used a vibration-minimizing restoration technique to preserve a mural by Jordi-Bonet.
Since the theatre’s operations had to be maintained during the work, we carried out the work quickly—on short notice.
Generated noise control
We minimized the noise generated by our work to prevent any disruptions to the Symphony Orchestra’s concerts.
