What a takeoff is
A quantity takeoff is the systematic counting and measuring of every material and labor item in a project from the plans. Done well, it is the foundation of a competitive, profitable bid. Done badly, it is the fastest way to lose money on a job.
Order of operations
Work top-down or bottom-up through the assembly. For framing, start with the foundation perimeter, then floor framing, then walls, then roof. Use highlight colors on the plans for each system so you do not double count or miss items.
Waste and contingency
Add a waste factor appropriate to the material: about 10 percent for lumber, 5 to 10 percent for drywall, 10 to 15 percent for tile. Add a separate contingency line on the estimate for unknowns, typically 5 to 10 percent on remodels and less on new construction.
