The new College of DuPage Amphitheater specifications called for an exterior architectural tensile fabric roof structure system. Eide Industries provided the value-engineering design, build and installation services to eliminate unnecessary ground obstacles from the original plans. The end result was a trussed perimeter “flying mast” tension structure using Sheerfill I-HT PTFE fabric membrane.

Despite the freezing & windy conditions of the Chicago suburbs, Eide Industries, Inc. completed the fabrication and installation of the College of DuPage Amphitheater Canopy in February 2013 for the newly renovated McAninch Arts Center (MAC) in Glen Ellyn, Illinois. This conical “flying mast” tension structure is the simplest form of tensegrity. The 2,520 square foot canopy rests on 10 foot tall concrete piers and is engineered for 90 MPH wind-loads, 25 PSF Ground snow-loads, and 12 PSF Roof Live snow-loads. The shade structure was also constructed with an intelligent LED lighting system that allows the glowing canopy to be seen from across the campus.

With the expanded spaces and public areas, the College of DuPage MAC Amphitheater (now referred to as the Lakeside Pavilion) has become ‘the’ destination to experience award winning music, performing arts and seasonal events.
