How to read this page
A filing history, not a rating.
This page groups filings by the applicant name published with each DOB record, and every figure on it is a count of those records: 4 new buildings, 3 alterations. It is a filing history, not a rating. Street Futures does not rank practices, verify their licences, judge their work or know anything about a job the city has no record of. Open an individual filing for its exact status, scope and identifiers.
Names are grouped exactly as the source publishes them, so a practice that files under more than one spelling may appear more than once. Which practices have the most open right now
