Residential conversion, 501 President Street, Brooklyn
Concord designed HVAC, plumbing and sprinkler work for the conversion of a three-story residential building at 501 President Street in Brooklyn into a four-story residential building with commercial space in the cellar, and took the backflow filings through NYC DEP.
The challenge
The conversion added a story and commercial space in the cellar. The building also got two new water services from the street, one domestic and one for the sprinklers, and each needed a backflow device approved by NYC DEP.
What Concord did
- HVAC, plumbing and sprinkler design for the conversion.
- Plumbing and sprinkler riser drawings, included in the DEP submission.
- Engineering report for water use: a new 1-1/2 in. domestic service with a 1-1/2 in. lead-free RPZ, and a new 2 in. sprinkler service with a 2 in. DCDA and bypass meter.
- The existing water service abandoned at the main, as DEP requires.
Outcome
- NYC DEP approved both backflow devices, and the converted building has a protected domestic service and a protected sprinkler service.
- The conversion work was completed in 2026.
