600,000 sq.ft.


$4 Million - Emergency Bracing

$20 Million - Structural Repairs +

The Marshak Science building is the largest and most important graduate science teaching facility on the college’s campus. It was built in 1971 and consists of a 450,000 sq. ft reinforced concrete tower above a 200,000 sq. ft plaza and athletic center. The tower cantilevers 27 ft. over the plaza on 2 elevations and has an exposed concrete frame on all 4 elevations.

Ten years after completion, the owner commissioned RSD to investigate the exterior structure to find the cause of the premature deterioration which turned out to be caused by the highly porous lightweight concrete in the exposed frame. RSD designed all repairs, the emergency bracing and the addition of a complex supporting structure for the new curtain wall.
