The doubly curving roof edge on the Antonov Auditorium called for specific expertise to develop the light-gauge framing and connection system. Radius Track Corporation created an assembly that tied the roof and metal façade into a structurally cohesive system. That connection strategy resolved the diaphragm and movement of the roof and façade interface, simplified the number of components within the system and streamlined installation.

A parametric design process was used to define the unique geometric shape of each of the 226 custom CFS folded sheet metal assemblies and light-gauge trusses that formed the perimeter of the roof. A sequence of the unique light-gauge folded plate components that were CNC fabricated with data extracted from the iterative development process is shown on the left. Above right is a single CFS template laid flat — with magnet tabs to be folded along the cyan lines.

Throughout the project, Radius Track integrated fabrication capabilities from each adjacent trade partner into the advanced 3D model for constructability. With the final information in the model, Radius Track coordinated with those trade partners and provided installation guidance according to their scope.
