Large clear span structure with tall eave height to accommodate multiple sporting events. Columns and mezzanine spaces are positioned outboard of the main building line to provide 100x50 yards of usable space. Elevated mezzanine areas provide additional space for viewing platforms, storage, and mechanical equipment. Turf floor system required special concrete tie beams underground to resist the thrust on the building columns. Large concrete plinths and isolated spread footings at the columns to anchor the columns.
