IS 109 Queens

A landmark candidate originally constructed in 1925, Intermediate School 109 in Queens suffered severe water infiltration for many years. Tasked with addressing the damage, Nelligan White designed an extensive campaign for complete masonry replacement, bringing new life to the historic building.

After careful inspection of the structure, we determined there was extensive deterioration in both the interior and exterior finishes of the building. In an effort to address the water infiltration, we undertook an all-inclusive replacement of the masonry for the 116,000 square-foot school.

By introducing a new face wythe masonry, we were able to install a continuous narrow-cavity drainage plane behind the face brick to tackle the large-scale steel deterioration. Further, we replaced every terra cotta structure on the shell with a cast stone replica for resilience. Damaged interior spaces were similarly overhauled with new finishes. As a result of the comprehensive project, IS 109 is now readily prepared for any event, rain or shine.
