The project is filed with the city and not yet approved; strip-out and structural work start once it is.
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.

| Framing | Mar 2026 – May 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.

Builtie groups the permits into projects and resolves the owner and builder separately.
