Commercial copper rough-ins in Bushwick involve supply sizing for the fixture schedule, threading and running copper mains to each fixture location, coordinating the rough-in with the concrete and framing trades, and scheduling the DOB inspection before anything closes. In gut buildouts where a previous plumber has started and backed out, the first step is assessing what was done and whether the sizing and routing decisions hold up before continuing.
A commercial tenant was building out raw space on Flushing Avenue, open slab, steel stud framing going in, GC needed a plumber who could thread and run copper on a commercial schedule. The previous plumber had backed out mid-job, leaving the supply rough-in incomplete with the tile contractor scheduled to start in three weeks. The previous plumber had also run 3/4-inch mains where the fixture schedule called for 1-inch headers. Undersized for the flush valve demand on that run.
We picked up the rough-in mid-project: assessed what had been started, re-ran two supply lines that weren't sized correctly, and completed the full copper rough-in to all fixture locations. Threaded the runs using a RIDGID 300 compact, pressure-tested the supply before the walls closed, and coordinated directly with the GC on inspection scheduling. The tile contractor started on time. Coordinated the DOB rough-in inspection directly with the GC's site super. Kept the schedule intact without a rescheduled inspection delay.
