Which trades are being bought now
Builtie estimates the stage from this building's own permits: the conversion filing is approved, with no site-work permit (cranes, hoists, scaffolds, sidewalk sheds or demolition) yet. The project is approved, with strip-out and structural work next.
When each trade on this project is usually picked, in calendar months (estimate). As of October 2026 every window below has passed (est.): the project may already be finished.
| Trade | When to approach (est.) | Status |
|---|---|---|
| Construction (est.) | Jun 2026 – Jan 2027 | Estimate |
| Construction Site Security | Jun 2026 – Jul 2026 | Window passed (est.) |
| Concrete and Foundation | Jun 2026 – Jul 2026 | Window passed (est.) |
| Structural Steel | Jun 2026 – Jul 2026 | Window passed (est.) |
| Elevators | Jun 2026 – Aug 2026 | Window passed (est.) |
| Framing | Jun 2026 – Aug 2026 | Window passed (est.) |
| Painting | Jul 2026 – Aug 2026 | Window passed (est.) |
How we estimate: each bar is the share of the build, from the estimated start (June 2026) to the estimated completion (January 2027) above, when the builder usually picks that trade. It is not the builder's schedule.

All of them: construction projects in New York City by address. All five boroughs are in the feed, which has run since February 27, 2026. New York issues separate permits for each trade, so the firm named on a permit is often the trade contractor, an engineer or an expediter rather than the developer. Builtie groups the permits into projects and resolves the owner and builder separately.
