Proj Overview

Project Overview

The $30 million Hempstead High School addition and renovation includes a new auditorium, gymnasium, locker and weight rooms, classrooms, art and music rooms, food prep/dining areas, and offices

Precast Solution

Structural/insulated precast wall panels provide high R-values. Use of custom form liners from US Form Liner, different reveal patterns, multiple colors and finishes provide dramatic and unique fluted designs.

Auditorium interior panels were produced with a stock form liner and stained by NawKaw. Exterior panels used a custom form liner. Exterior panels feature a green colored mix and light acid etched finish. Gymnasium panels feature a green and buff colored mix with reveals and light acid etched finish. Panels on the educational wing consist of a buff colored mix with acid etched finish.

Precast hollow planks were used for a portion of the gymnasium floor over the locker rooms, ceilings over the tunnels for the auditorium, and a mezzanine in the education wing.
