From the pedestrian plaza in Times Square to the Far Rockaway Library, the Department of Design and Construction is building for you.

As the City's primary capital construction project manager, we build many of the civic facilities New Yorkers use every day. We provide communities with new or renovated structures such as firehouses, libraries, police precincts, courthouses, senior centers and more. To successfully manage our portfolio, we collaborate with other City agencies, as well as with emerging and world-renowned architects and consultants.

Our work doesn’t stop at buildings—we also design and improve vital infrastructure.

Our staff delivers roadway, sewer and water main construction projects in all five boroughs. We provide sidewalks, street reconstruction, water mains, sewers, and pedestrian ramps—quality infrastructure that is essential for a healthy, resilient city.

As our city grows, so does DDC. Join us and help build a resilient, healthy city for all.
