We design, renovate and build the structures that New York City needs to serve the public. 

We build libraries, museums, police precincts, senior centers, and beyond. Our portfolio of smaller-scale work promotes safety for all, from the installation of wheelchair-accessible pedestrian ramps, to the upgrade of fire hydrants throughout the City. We also make improvements to the City’s complex infrastructure system, ensuring that New Yorkers will always have access to clean drinking water.

With non-stop improvement happening in every borough, we do our best to be a good neighbor. If you notice our crews in your neighborhood, our Office of Community Outreach and Notification can answer questions and give you the latest news.
