Years Shaping
New York City

WE BUILD
THIS
CITY.

Founded in 2001 by third-generation New York ironworker James Cortlandt, Ironworks Construction Co. has spent over two decades raising the skyline of the five boroughs. We've built the offices, residences, and retail spaces that define modern New York.

Our crews are local — mostly Brooklyn, the Bronx, and Queens — and every foreman is a journeyman with 10+ years on New York job sites. No subcontracting guesswork. No coast-to-coast crews that don't know this city's code.

  • NYC Department of Buildings Registered General Contractor
  • OSHA 30 certified workforce — 300+ skilled tradespeople
  • Minority & Women-Owned Business Enterprise (M/WBE) Certified
  • Union affiliated — Carpenters Local 608, Ironworkers Local 40
  • $50M liability insurance · bonded on all public work

02
Permits & Planning
Our expeditors navigate NYC DOB filings, landmark approvals, and community board processes so you don't have to.
03
Build & Report
Weekly progress reports, a dedicated super on-site, and a client dashboard that shows you the project in real time.
04
Delivery & Warranty
Final walkthroughs, certificate of occupancy, punch-list resolution, and a 2-year workmanship warranty on all projects.
