BC Place Stadium

The redevelopment of BC Place Stadium replaced the original air-supported roof with an innovative cable-supported membrane structure featuring a retractable central section. The lightweight roof is supported by 36 perimeter masts and a prestressed cable-net system comprising approximately 860 tonnes of cables. Around 35,500 m² of PTFE membrane forms the permanent weather-resistant roof, while the retractable inner section opens the stadium to the sky and can be closed within approximately ten minutes.

PFEIFER Structures was responsible for the installation of 36 outer and 36 inner fixed PTFE membrane panels. The large-format outer panels span up to approximately 67 metres and cover around 929 m² each. Despite the demanding geometry and installation conditions, all 72 panels were installed within just 44 calendar days.

PFEIFER Structures also contributed to the development and design of the flexible perimeter closure between the fixed PTFE roof and the transparent ETFE façade. Acting as an expansion joint, this specialised membrane detail accommodates vertical movements of more than 0.46 metres while maintaining a reliable, weather-resistant connection. The completed roof combines structural efficiency, operational flexibility and a distinctive architectural appearance, creating a modern open-air stadium experience in the heart of Vancouver.
