Estimator

Preconstruction & Estimating

Prices the job before anyone breaks ground, so the bid actually makes money instead of just winning the work.

What is a Estimator?

An Estimator figures out what a project will cost before construction starts, so the company can submit a competitive bid that still leaves room for profit. That means measuring quantities directly off the drawings (a "takeoff": how much concrete, how many linear feet of wall, how many doors), then pricing each one using current material costs, labor rates, and subcontractor quotes.

What they do

• Perform quantity takeoffs from architectural and engineering drawings
• Solicit and compare pricing quotes from subcontractors and material suppliers
• Build a complete bid, choosing lump sum, unit price, or cost-plus pricing depending on what the owner asked for
• Track historical unit costs (cost per square foot, per linear foot, etc.) to sanity-check new bids
• Identify scope gaps or ambiguities in the drawings before they become expensive change orders later
• Hand off the winning bid's assumptions to the project manager so the budget they inherit is accurate

A typical day

• 8:00 AMReview a new project's drawings and specs to scope out what needs a takeoff
• 9:30 AMMeasure quantities off the drawings using takeoff software
• 11:00 AMCall two subcontractors to clarify quotes that came in with different scope assumptions
• 1:30 PMBuild the bid summary, checking the total against a similar recently-completed project
• 4:00 PMWalk the near-final bid with a senior estimator before it goes out the door

Pay expectations

Reviewed October 2026. Estimator is typically reached through promotion or years of experience in a related role, not a day-one starting point, so this chart shows the pay range for people already working as a Estimator rather than entry-level pay. "Lower range" is the lower part of the national wage distribution for this occupation, "typical" sits around the national median, and "top of scale" is the upper part, since pay isn't actually tracked by years on the job. Real pay varies a lot by state, metro area, union status, and employer, so scale these up or down for your market.

Education

Required:

High school diploma or equivalent

Preferred:

Bachelor's degree in construction management, civil engineering, or a related field

Helpful:

Certified Professional Estimator (CPE) credential

Not necessary:

A specific estimating degree; many estimators move into the role from the trades or from a project engineer track rather than starting there
