Staten Island, NY

Monsignor Farrell High School


Monsignor Farrell High School, constructed in the early 1960s, is a multibuilding Catholic school for boys in the Archdiocese of New York. School staff reported building performance issues and distress in exterior masonry walls. SGH helped the school investigate the cause of the issues and develop remedial plans.

The administration, classroom, and gymnasium wings experienced chronic water leakage, resulting in damage to the facade and interior finishes. Staff and students also complained of uncomfortable thermal conditions in the school due to lack of insulation in the walls and the thermal transmission through the original single-glazed windows. SGH diagnosed the sources of the water leakage through the roofs, walls, and windows. During our investigation, we uncovered brick masonry walls requiring repairs.

Serving as the designer of record, SGH designed repairs to mitigate the water leakage, address structural issues, and improve thermal comfort. We developed a phased approach to the work allowing construction to occur primarily during summer breaks to minimize the disruption to school activities.

SGH provided construction administration services for building enclosure repairs, including replacing roofing on all buildings; removing and reconstructing brick masonry walls in the classroom building and computer room to add insulation, weather-resistive barriers, and through‑wall flashings; replacing windows in the classroom building and computer room with dual‑glazed thermally broken units; and replacing the chapel skylight.
