Extensive exterior surveys we conducted in 2015 revealed masonry failures such as cracking, spalling, and missing mortar, as well as minimal reinforcement of the face block to the wall behind it, creating potentially unsafe conditions for students and community residents. Our assessments indicated the need to replace the existing face masonry and waterproof the backup…
IS 77 Queens represents an early example of the Type-A school, a popularized building concept from the turn of the 20th century designed to be constructed rapidly for growing neighborhoods. Nearly a century later, the five-story, 135,000 square-foot structure was no longer fit to contemporary standards. Experiencing extensive water-infiltration damage, Nelligan White was tapped to…
Built in 1891, the Bedford-Atlantic Armory is an outstanding example of a late nineteenth-century National Guard Armory in New York City. It is the second largest armory ever built in New York City. Originally the home of the 23rd regiment, it has since served as both a homeless shelter and a stage set for films…
Inspections include brick masonry, decorative façade elements, bulkheads and water towers, windows, air conditioners, satellite dishes, and load-testing of fire escape and balcony railings. This work is performed in concert with façade renovation work in order to remove sidewalk bridges and reduce ongoing costs.
The auditorium is over 10,000 square feet, with a balcony, and is rendered in Collegiate Gothic style, with ornate plaster columns and architectural detailing. Of note are the molded plaster figures (grotesques) at the spring points of each of the plaster arches that span the aisles. Severe deterioration of much of the detailed plaster and…
IS 201 Brooklyn is a junior high school (grades 6 – 8) for 1532 students and 175 staff. It was designed by William H. Gompert in 1924 along 12th Avenue (between 80th and 81st Streets) in the Dyker Heights neighborhood of Brooklyn. This building shell renovation includes the removal of all face brick masonry and…
In its many decades of use, moisture ingress began to jeopardize the school’s structural stability. Nelligan White was commissioned to examine the damage and propose a strategy for long-term flood elimination in response to these concerns. After a thorough firsthand examination, our team attributed the school’s extensive water damage to previous projects’ failed attempts to…
The project focused on restoring a 1938 addition and its distinct low-slope roof and brick-masonry parapets with precast concrete coping stones. Suffering extensive damage to the exterior from flooding and age, Nelligan White set out to restore the building to full functionality and structural integrity. In addition to water infiltration from the roof drain at…
Originally it was the Old Westchester Square Municipal Court, but today it’s the Parking Violations Bureau and Highway Operations office for the Department of Transportation. This building suffered from years of neglect that led to potentially hazardous conditions. Our firm executed a renovation improving accessibility, facade rehabilitation, and roof replacement.
To address the escalating cycle of façade failures, we first removed the entire outer layer of brickwork. We then installed new masonry, added a narrow cavity drainage plane, and spray-applied a vapor-permeable membrane to improve the building’s insulation and protect it for the foreseeable future. All windows in the building were replaced as well as…
