After the concept presentation and approval phase is complete, and after an in-depth review of bay assembly, crane lifts and installation procedures, comes the installation process. In order to meet the completion deadline of September 30th, 2011, on BC Place’s roof replacement in Vancouver, Canada, the massive job required a field force of 80-85 experts per day, working up to 7 days a week, 12 hours a day. The crew installed 72 panels in just 44 calendar days.
The fixed fabric roof covering the stadium’s 54,500 all-new seats, is comprised of 36 outer panels, each approximately 220 feet long and 10,000 square feet in surface area; and 36 liner panels, each approximately 120 feet long and 6,000 square feet in surface area. The outer membrane is Sheerfill I and the liner membrane is Fabrasorb.
The fabric structure team was instrumental in the development and design of the flexible perimeter system that closes the area between the ETFE façade panels and the fixed fabric roof panels. Effectively, the perimeter closure system is an expansion joint between the membrane roof panels and the fixed steel framed façade that had to accommodate vertical deflections of 1.7 feet. The fabric structure team developed a tensioned fabric hinge panel and utilized a Ferrari 1002S fabric for the construction of the 36 panels. The total surface are of the perimeter closure system was approximately 18,770 square feet.
