Type of works: design, manufacture and installation of structural and glazing systems for atrium skylight.
The William Wrigley Jr. Company sought to establish a new Innovation Center in Chicago. In the center of the building the client wanted a large atrium space that would create a winter garden with a large skylight. To maximize transparency, the architect wanted to eliminate all structural support except for the skylight mullions. Novum engineers utilized steel mullions and tension cables to achieve the impressively large span of 130 ft for the grid shell structure. The project resulted in a highly successful execution of the first grid shell skylight ever built in the United States.
BK, DC and TC solid steel nodes attach to the primary structure of hollow steel tubes. Steel tension cables underneath the structure are fixed at each node by stainless-steel disc clamps. LSG glazing attaches to an aluminium track system via toggle bolts and is supported by a linear gasket system.
