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.) | Mar 2026 – Oct 2026 | Estimate |
| Construction Site Security | Mar 2026 – Apr 2026 | Window passed (est.) |

| Framing | Mar 2026 – May 2026 | Window passed (est.) |
| Painting | Apr 2026 – Jun 2026 | Window passed (est.) |
How we estimate: each bar is the share of the build, from the estimated start (March 2026) to the estimated completion (October 2026) 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.
