NYC Department of Design and Construction (DDC) The city agency that manages large-scale public infrastructure and capital construction projects, including certain streetscape and sidewalk reconstruction work.
DDC typically gets involved in bigger, city-funded projects — full block reconstructions, major infrastructure upgrades, or public plaza redesigns — rather than the routine private-property sidewalk repairs that fall under DOT's violation and permit process. Its engineers can also weigh in on specialized construction decisions, such as flag replacement decisions in complex sidewalk-over-vault situations. Most property owners handling a standard cited repair won't interact with DDC directly, but its standards can influence the broader sidewalk specifications DOT enforces.
