Comply with NYC Local Law 15 of 2020 bird-friendly glazing material requirements on a curtain wall submittal

Steps

1. Confirm the current text and any amendments to Local Law 15 of 2020 and its implementing DOB bulletin/guidance document on nyc.gov before applying it, since bulletins are periodically updated.
2. Confirm the law's height/location triggers as currently published — generally exterior wall envelope up to 75 feet above grade, glazing adjacent to green roofs up to 12 feet above the walking surface, and any bird hazard installation regardless of height — but verify these thresholds against the current DOB guidance rather than a secondary summary.
3. Confirm the material threat-factor rating threshold (materials scoring at or below the current published threshold on the referenced bird-collision threat factor rating scale) required for compliance, and require manufacturer documentation of the tested rating for the specific glazing product/pattern proposed.
4. Verify the compliance pathway applies based on filing date (new construction and qualifying alterations filed on or after the law's effective date) — confirm this against DOB's current guidance for the specific project filing.
5. Coordinate with the DOB plan examiner on acceptable documentation format for demonstrating compliance in construction documents, since bird-friendly compliance is typically documented via a schedule/legend on the drawings.
