Allan Rosenfield Bldg.: Facade Repairs, Fall 2024- Summer 2025

Beginning on Wednesday, August 30, we will be conducting façade repairs at the Allan Rosenfield Building. These repairs are being completed in accordance with Local Law 11, a New York City law that requires property owners to inspect all exterior walls of commercial and residential buildings higher than six stories every five years.

Highlights of what to expect:

•  With the scaffolding is in place, construction activity will take place from 8 a.m. to 5 p.m., Mondays through Fridays.
• The contractor will be performing the inspections and maintenance from suspended scaffolds on the exterior of the building; access to the inside of the building is generally not required.
• There will be periods of increased noise due to minor drilling in some areas of the building facade to remove the damaged brick, stone, or mortar.
• During this time, please keep windows and shades closed, especially in sensitive areas, e.g. patient care areas.
• Site protection, including flag persons and safety cones, will be present.

We anticipate the repair work will conclude in summer 2025. Activities listed are subject to change based on approval, University events, other requirements, and unforeseen circumstances.

We appreciate your cooperation as we work to improve our facilities. For any questions or concerns, please contact Sonya Chao, project manager, at yc4268@cumc.columbia.edu.
