Infinity Windows



Designed and built a new 195,824 square foot precast manufacturing plant that includes a 193,000 square foot production area, a 2,824 square foot office area and an associated car parking lot. Included all site work, precast concrete walls, reinforced concrete floors, hazardous material storage, fire sprinkler system, conference room, employee dining area, mailroom, IT space, staff support areas, loading docks, truck ramps and all infrastructure.

The structural system included cast in place foundations and spread footings, hot-rolled columns and four bays of eccentrically braced frames in conjunction with precast shear walls, and steel joists and joist girders and a complete structural expansion and isolation joint that split facility into two independent halves. Moment frames utilizing 48” joist girders and W16 x 67 columns were also used at the side of the separation joint. This allowed for a clear access between the halves without any sheer bracing panels that would obstruct the material flow of the manufacturing process.

The structure was designed to readily add an addition along the north exterior wall. Concrete piers sized for future gravity and wind bracing loads were installed, the exterior precast wall panels were attached using details that allow easy removal of the wall panels for the future expansion of the plant.
