Prism at Park Avenue South Apartments

Located in the Madison Square North (NoMad) section of Manhattan, this 40-story residential tower (476-FT) has a combined total of 363 apartments and condominiums. The development scope included demolition of existing structures, excavation to 30 feet below sidewalk grade, construction of the 40-story tower, and replacement of a portion of the adjacent subway station. Langan geotechnical engineers performed two phases of site investigation and provided design and construction recommendations to satisfy project needs and New York City Department of Buildings requirements. Our environmental engineers performed waste characterization and provided coordination with NYCOER that included remediation investigation and oversight, and a successful Voluntary Cleanup Program Brownfield Incentive Grant Application.
