PS 121 Queens

A landmark candidate originally constructed in 1924, Public School 121 in Queens suffered deterioration in the exterior shell and water intrusion on the upper floors. Tasked with addressing the damage, Nelligan White designed a selective campaign for masonry replacement, bringing new life to the historic building.

After a comprehensive water infiltration survey of the 99,500 square-foot building, we determined that the damage was a result of a failing parapet wall and waterproof roofing. In order to arrest the deterioration of the exterior shell and the water intrusion at the upper levels, we executed a replacement of the brick masonry and the installation of a new parapet wall. Decorative terra cotta balusters and panels were replicated in cast stone and also replaced. In addition, the accessibility ramp at the front entrance was rebuilt and modernized.

In 2017, Nelligan White further performed a Resolution A funded auditorium upgrade for the school building. We replaced the VCT stage floor, PA system, and stage curtain. New flat-screen televisions and electrical outlets for air conditioners were installed, and the entire structural floor was repaired.

This project was substantially completed in January 2020.
