Many people believe estimating accuracy comes from knowing material prices.
Pricing is important, but it is only one part of the equation. The foundation of every estimate is quantity accuracy. If your quantities are incomplete, even perfect pricing cannot save the bid.
Accurate bids are built through a disciplined process:
- Review drawings carefully: Read the general notes, structural schedules, and specs before measuring.
- Identify scope completely: Don't focus only on plan views; look at wall sections and details.
- Verify quantities: Perform scaling checks to make sure the drawing scale settings are correct.
- Document assumptions: Note down any missing information or clarifications needed from the designer.
- Perform quality control: Have another estimator check the formulas and counts.
Contractors who consistently follow this process produce more reliable bids and experience fewer surprises after award. Estimating is not simply math. It is a process of reducing uncertainty before construction begins.
