Department of Design and Construction

NYC's general contractor -- DDC manages the design and construction of the city's public buildings and infrastructure. That means libraries, fire stations, courthouses, sewers, water mains, streetscapes, and coastal resilience projects, built on behalf of other city agencies. When a new library opens, a sewer gets upgraded, or a recreation center gets built, DDC is the agency that actually managed the construction. If public projects come in late and over budget, that's often a DDC problem.
