How Plumbing Takeoffs Work for GCs and Subcontractors

Quick answerA plumbing takeoff counts every fixture, foot of pipe by size and material, fitting, valve and piece of equipment on the drawings, organized by system and area. GCs use it to check sub bids and find scope gaps; subs use it to price labor and material faster.

What gets counted

  • Fixtures and equipment from the schedules
  • Pipe by system (domestic cold, hot, recirculation, sanitary, vent, storm, gas, condensate), size and material
  • Fittings, valves, cleanouts, hangers and specialties
  • Interceptors, water heaters, pumps and backflow assemblies

How it's organized

By system, then by floor or area, with material and size subtotals. That structure lets you apply your own unit pricing or compare directly against sub proposals.

What we need

Plumbing and architectural PDFs, specs, addenda and the bid due date. Incomplete drawings are common, so every takeoff includes a list of conflicts and missing information.

Turning quantities into a decision

Pair a takeoff with bid leveling to see exactly what each sub carries. Not ready to bid? Check project readiness first.
