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
Pay by experience, nationally
as of May 2025
Source: U.S. Bureau of Labor Statistics, Occupational Employment and Wage Statistics (OEWS), Cost Estimators (SOC 13-1051), national data — BLS doesn't track estimating/cost specialties as separate detailed occupations, so Estimator, Heavy Civil Estimator, Cost Engineer, and Quantity Surveyor all share this code and use the standard entry/median-75th/75th-90th mapping; see Bid Coordinator and Senior Estimator for the lower and upper parts of the same distribution
Reviewed May 2025. Pay reflects the national wage distribution for this occupation, not a promise for any one job: entry level is the lower part of that range, 5 years in sits around the national median, and 10 years in 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 — scale these up or down for your market. These figures are base pay only: overtime, shift differentials, and per-project bonuses are standard across most construction trades and routinely push real earnings above what's shown here.
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
