611th 112th Street Renovation

The renovation of the historic landmark building at 611 West 112th Street, originally constructed in 1904 and converted to Single-Room Occupancy housing in the 1940s, represents a pivotal transformation within the Morningside Heights Historic District. This new residence hall is a key component of Columbia University’s commitment to electrifying its portfolio as part of its net-zero initiative.

The fast-track project will include 83 student residences, communal spaces and a dining area. The project scope entails comprehensive demolition, shoring, and the structural replacement of all floors and roofs, along with the installation of new interior finishes, lighting, and M/E/P systems. The building’s exterior will undergo meticulous restoration, including masonry repairs, window replacements and terracotta restoration. Early in pre-construction, Consigli conducted an in-depth building investigation using laser scanning and existing conditions surveys. To ensure structural integrity, the existing perimeter masonry walls will be shored and laterally braced ahead of the full demolition of all floors, roofs, and parapets. Extensive coordination with neighborhood tenants and the adjacent elementary school has been crucial to ensuring safety and minimizing disruption throughout the project. The residence hall will feature all-electric Variable Refrigerant Flow (VRF) Heat Pumps, CO2 heat pumps and  a Dedicated Outside Air System (DOAS) with Energy Recovery to promote energy conservation. The building envelope will be upgraded with enhanced insulation and high-performance Low-E coated double-pane windows to improve energy efficiency. This project is pursuing a LEED Silver Certification; this would be the first undergraduate residence hall at the University to achieve LEED certification.
