📏 Module 3: Plumbing Takeoff Process
Master the step-by-step process of taking off quantities from plumbing drawings to build a complete estimate.
🎯 Learning Objectives
This module focuses on breaking down drawings into measurable scopes and quantifying material and labor items from each plan set.
📌 Identify Takeoff Areas by Scope (Water, Sewer, Gas, Vent)
Learn how to separate the takeoff into systems such as domestic water, waste and vent, gas piping, and storm. This helps organize your estimate by system and match plan sheets to scope.
📌 Use Color Coding for Clarity and Accuracy
Color coding your drawings is an industry best practice. You'll learn how to assign colors to each system and avoid overlapping quantities. This also helps you double-check your work.
📌 Count Fixtures and Pipe Lengths
Using your plans and risers, you’ll identify all plumbing fixtures, pipe types, and lengths. This includes isolating horizontal vs. vertical lengths and labeling by pipe size when needed.
📌 Track Quantities in a Spreadsheet or Takeoff Sheet
We’ll show how to enter quantities into a structured spreadsheet. This includes labeling the area/room, entering counts, assigning unit labor and material rates, and totaling each system.
📌 Review for Omissions Before Estimating
Before pricing, estimators should review all plans, cross-check fixture schedules, and verify shutoffs, cleanouts, and special piping. This step prevents common omissions that reduce profit.
