Hiring and people

How to hire a construction estimator

Hire an estimator when bids are being skipped, rushed, or held up by the owner. Define the trades and job sizes they will price, test candidates with a takeoff and pricing exercise from a real past bid, and keep the owner reviewing bids until the new estimator's numbers prove out on finished jobs.

To hire a construction estimator, decide first what kind you need (a takeoff-focused junior, a trade specialist, or a senior estimator who can run bid day and build your cost database), set pay from current market data, and look for candidates among estimators at suppliers, subs, and larger contractors as well as on job boards. The most important step is a practical test: hand finalists the plans and specs from a job you already bid, ask for a takeoff and price on a defined scope, and compare their work to your own number and to what the job actually cost. Then keep reviewing their bids until a handful of their jobs close out at the margin they estimated.

Signs you need an estimator

  • You pass on bids you want because nobody has time to price them.
  • Bids go out late at night with no second check.
  • The owner spends most of the week on takeoffs instead of sales and management.
  • Your bid hit ratio is unclear because you are not tracking what you bid.
  • Finished jobs keep coming in below estimated margin and nobody has time to find out why.

Step 1: Define the role

Write down the trades and scopes they will price, typical job sizes, number of bids a month, delivery methods (hard bid, negotiated, design-assist), and software. Decide who owns final pricing and markup. Many contractors have the estimator build direct cost and the owner set the markup and fee. Also decide whether the estimator stays involved after award, at the handoff to operations and in post-job reviews. They should. That is how estimates get better.

Step 2: Set the pay range

The U.S. Bureau of Labor Statistics reports a median annual wage of $78,740 for cost estimators as of May 2025. BLS lists a bachelor's degree as the typical entry-level education, with moderate-term on-the-job training, and notes most estimators learn estimating techniques and software on the job. Its projection for the occupation as a whole is a 3 percent decline from 2025 to 2035. The BLS category includes estimators outside construction, so use it as a reference and check local postings for your trade and region. A senior estimator who can run bid day and has relationships with subs may command well above a takeoff estimator.

Step 3: Find candidates

  • Supplier and distributor estimators who price takeoffs for contractors every day.
  • Estimators at subcontractors in your trade if you are a GC, or at GCs if you are a sub.
  • Project engineers and assistant PMs who want to move into preconstruction.
  • Experienced foremen with good math and computer skills for self-perform trades.
  • Construction management and engineering programs for junior roles.
  • Referrals from your subs and suppliers, who know who sends clean bid packages.

Step 4: Interview with a takeoff test

Interviews alone are a poor guide. Use a test built from a job you already bid and built, so you know the right answer.

  1. Pick a modest scope: a set of drawings for one area, the relevant spec sections, and your labor rates.
  2. Ask for a quantity takeoff, a labor and material price, and a list of clarifications and exclusions.
  3. Allow two to four hours, at your office or as a paid take-home.
  4. Compare their quantities to yours, their labor hours to actual job cost, and their exclusions to what caused problems on the real job.

Good answers are not always the closest number. A candidate who is 5 percent off on quantity but catches a spec requirement your team missed may be the better hire.

Questions worth asking

  • How do you price labor productivity, and where do your production rates come from?
  • Tell me about a bid you won that lost money. What did you miss?
  • How do you level subcontractor bids when scopes do not match?
  • What goes into your general conditions, and how do you price duration?
  • How do you decide a job is not worth bidding?

Worked example: a test that changed the hire

Say a commercial drywall and framing sub tests two finalists on a past $410,000 office job that actually came in at 2,950 labor hours. Candidate A, from a larger GC, prices 2,400 hours and a tidy proposal. Candidate B, a former foreman, prices 2,880 hours, flags a deflection head detail at every exterior wall, and adds a clarification on the ceiling heights. The job had in fact lost money on that head detail. Candidate B is hired, paired with the owner on markup for six months, and trained on the company's software. These numbers are illustrative, but the pattern is common: field knowledge of labor often matters more than polished paperwork.

Step 5: Onboard and protect bid quality

  • Give them your cost history, production rates, and standard exclusions. If you have none, building that database is their first project; see how to build an estimating database.
  • Review every bid before it goes out for the first few months, then only bids over a set size.
  • Hold a bid review after each award and a margin review at closeout, comparing estimate to actual.
  • Track bids, wins, and losses so you can measure them fairly.

How to judge the new estimator after six months

Do not judge on win rate alone. An estimator who wins everything is probably leaving money on the table, and one who wins nothing may be pricing scope the market does not include. Look at three things together: how many bids they produced, how their numbers compared to the low bidder when you lost, and how the jobs they priced are tracking against estimate on the job cost report. A few closed jobs at or above estimated margin are the real proof.

Mistakes to avoid

  1. Hiring for software skill alone. Software counts quantities. It does not know how long a crew takes to hang board at 14 feet.
  2. No feedback loop. If estimators never see final job costs, their numbers never improve.
  3. Paying on volume of bids. That rewards speed over accuracy.
  4. Letting the new hire set markup on day one. Keep pricing strategy with the owner until trust is earned.
  5. Skipping the test. It is the single best predictor you have.

Once a bid is won, Smart Business Automator carries the estimate's budget and scope into the project so the PM starts from the estimator's numbers. See estimate to project handoff automation.

Frequently asked questions

How much does a construction estimator make?

The Bureau of Labor Statistics reports a median annual wage of $78,740 for cost estimators as of May 2025. Pay for construction estimators varies by trade, region, and seniority, so compare local postings.

What qualifications should a construction estimator have?

BLS lists a bachelor's degree as typical, but many construction estimators come from the field or from supplier and project engineer roles. A practical takeoff and pricing test tells you more than credentials.

When should a contractor hire its first estimator?

When the owner cannot price all the work worth bidding, bids are rushed without review, or estimating time is keeping the owner from sales and management.

How do I test a construction estimator?

Give them plans and specs from a job you already bid and built, ask for a takeoff, price, and exclusions on a defined scope, and compare to your estimate and the actual job cost.
