PS 277 Bronx is a wonderful example of C.B.J. Snyder’s iconic design in the English-Flemish renaissance revival style. There are so few of these ornate schools remaining today. This building is distinguished by its light-colored face-brick, limestone, terra cotta ornamentations, mansard roof, and the central spire. The structural system of this building is an early example of a masonry and steel structure. This building experienced extensive water penetration over the years resulting in problematic structural conditions such as corroded steel. After years of corrosion and expansion the stress provided enough tension to crack the exterior masonry.
Exploratory probes and material testing were applied to investigate problematic conditions and water infiltration points. Water ingress around the windows was discovered as a major source of water infiltration. The removal and reinstallation of windows were a necessary step to achieve a water tight seal and to allow installment of proper waterproofing elements. Roofing ventilation proved to be another challenging element exhibiting a critical life safety issue. Steps were taken and a full analysis was conducted of the building resulting in the restoration and upgrade of the roof, exterior masonry, windows, parapets and heating plant.
