Map openings and protection
For each route, list likely wall, ceiling, cabinet or chase access. Record furniture moves, floor protection, dust boundaries and occupied-room constraints. Begin the piping map with a date and its branch, fixture and room; attach the available evidence before making the pipe, access or restoration decision. The next checkpoint is “Distinguish exploratory openings from production access.” Plan secure daily closeout. Keep that action beside its observation. The repipe-scope reviewer can then distinguish the intake piping map from repipe closeout package material added during later pricing or investigation.
