Roofing contractor Bothwell-Accurate considered the challenges presented by the Vaughan Centre roof and requested that Radius Track Corporation design and fabricate the roof sub-system instead of wood blocking as originally specified. The Bothwell team looked to Radius Track to provide a fully engineered solution that accounted for:
  • Multiple skylight penetrations
  • A complex geometric shape
  • A segmented metal deck under a curved zinc surface requiring variable height connections
By developing a unitized solution, Radius Track helped Bothwell successfully deliver the project through predictability, performance and efficiency, including verification and coordination during site visits.

Predictability
– the 3D framing model was developed from a 3D scan which precisely located each skylight, and height variation between deck and skin.

Performance
– the light-gauge framing is dimensionally stable and was CNC fabricated to an 1/8” tolerance using data extracted from the 3D model.

Efficiency
– Radius Track created a jig for Bothwell to use on site to pre-assemble components for rapid installation. Each light-gauge component was color-coded to match installation drawings and ensure correct placement.

“The Radius Track framing made it happen,” said Trevor McGrath, Bothwell-Accurate Estimating Manager, “They provided excellent service and product.”
