A cost consultant in an owner’s representative practice defends the owner’s budget: the independent estimate, the GMP review, change-order and pay-application scrutiny, and the cost-to-complete the owner reports upward. The technical skill is a contractor estimator’s; the posture is the reverse. Hire for someone who can tell a client and a contractor the number is wrong, and price the seat as a consultancy hire, not a contractor one.
The cost consultant an owner’s representative practice most wants to hire is the chief estimator who just priced the contractor’s last GMP. It is also the hire most likely to go wrong.
The technical skill is identical. Takeoff, unit rates, escalation, contingency, the anatomy of a general conditions line: a good contractor estimator carries all of it and could produce the owner’s independent estimate on day one. What they have never done is sit across the table from a contractor with a number and say, in front of the client, that it is too high, and then defend that position for the rest of the project.
That posture is the seat. The résumé cannot show it, and most briefs written for the role do not ask for it, because the principal writing the brief assumes that anyone who can price work can also argue about the price.
What does a cost consultant in an owner’s representative practice own?
The owner’s number. A cost consultant in an owner’s representative practice produces the budget before a contractor is appointed, the independent estimate the contractor’s GMP is tested against, the review of every change order and pay application, and the cost-to-complete the owner reports upward. Every one of those is a position against someone else’s figure.
Walk the project from the owner’s chair and the shape of the seat becomes clear.
Before a contractor exists, the cost consultant sets the budget the owner will raise money against. On a public project, or one drawing federal funds through a program administered under FHWA or similar rules, that budget becomes the number the owner is accountable for, and the consultant who set it will be asked to explain every subsequent variance.
At GMP, the consultant produces an independent estimate and reconciles it line by line with the contractor’s. This is the moment the seat is decided. The contractor’s estimator has priced the work to win it and has a contingency and a fee to protect. The owner’s consultant has to find the lines where the two estimates diverge, decide which side is right, and say so. A reconciliation that ends with the consultant agreeing to every contractor line has not happened.
During construction, the consultant reviews change orders and pay applications against the schedule of values. The contractor’s change order is a claim; the consultant’s review is the owner’s defense, and on the other side of the table the contractor’s change-order manager is building the case the consultant has to answer. The FAR cost principles are the federal statement of what is allowable and what is not, and a private owner’s review mirrors the same logic whether or not the contract cites them.
At every reporting date, the consultant produces the cost-to-complete the owner carries upward. The Census Bureau spending series measures the aggregate; the consultant’s forecast is the owner’s own slice of it, and it has to be defensible to a board that will remember the original budget.
Every stage is adversarial in a way the contractor’s seat is not, and that is what most candidates from the contractor side have not done.
Why do contractor estimators struggle on the owner’s side?
Because the skill transfers and the posture does not. A contractor’s estimator prices work to win it and defends the estimate inside the firm. An owner’s cost consultant prices work to test a contractor’s number and defends the test outside it, to a client who wants to proceed and a contractor who wants acceptance.
Three specific habits get in the way, and each is a strength on the contractor side.
The first is the instinct to be reasonable with the contractor. A good chief estimator has spent a career building relationships with subcontractors and general contractors, and reads a reconciliation meeting as a negotiation to be closed. The owner’s consultant reads it as an audit to be completed. The two produce different numbers.
The second is deference to the person who has to build it. A contractor’s estimator knows the field team will live with the price, and prices accordingly. The owner’s consultant has no field team and a client who will live with the total, and has to be willing to say that the contractor’s general conditions are ten weeks too long without having to staff those ten weeks.
The third is the reporting audience. A contractor’s estimator reports to a president who wants to win the job. The owner’s consultant reports to a principal whose client is a hospital board, a school district or a developer’s lender, and the BLS cost estimator profile describes the shared technical work without capturing that the audience is the whole difference.
| Contractor estimator habit | What the owner’s seat needs instead |
|---|---|
| Price to win | Price to test |
| Close the reconciliation | Complete the reconciliation |
| Protect the field team’s price | Protect the owner’s total |
| Report to a president who wants the job | Report to a client who wants the truth |
| Relationship with subs | Independence from subs |
| One firm’s number | Two numbers, and a written position on the gap |
The right column is a temperament as much as a skill. The candidates who make the switch cleanly are the ones who were already uncomfortable with the first column: the estimator who kept pushing back on a president who wanted a lower bid, the preconstruction manager who insisted the contingency was too thin. That discomfort is the signal. The preconstruction and cost control search piece sets out how the contractor-side seats are scoped; this one is their mirror, and the contractor-side seat that most closely mirrors it day to day is the cost control manager.
Which raises the question of where the candidates who already have the posture come from, and what the practice should pay for them.
Where does an owner-side cost consultant come from and what does the seat pay?
From other consultancies first, from cost-management practices attached to program managers second, and from the contractor side third, with a specific test applied. The pool is small in any metro, and the seat is priced as a consultancy hire, meaning against the practice’s fee model rather than against contractor salary bands.
The vocabulary matters more here than on any contractor search. Practices founded by UK-trained principals write the brief for a quantity surveyor; the strongest US candidates call themselves cost managers, cost consultants or senior estimators and will not recognize the term. Write it in US vocabulary and pair it once, so a candidate from either background reads the same role. The quantity surveyor piece covers that translation in more depth. Selah runs this as a cost manager search.
Price the seat off the practice’s economics. A cost consultant billing at consultancy rates carries a utilization target, and the salary has to sit inside the fee the practice earns on the projects the consultant serves. The BLS OEWS cost estimator tables give the distribution the seat sits above; the metropolitan area tables split it by market, and a practice in Dallas or Houston is competing against contractors’ preconstruction departments for the same people, at contractor prices.
That competition is the practice’s real hiring problem. In the 2025 AGC and NCCER workforce survey, 91.7 percent of the 1,041 contractors answering the salaried-hiring question reported difficulty filling salaried positions, and the AGC release reports estimating among the harder seats to fill. Every contractor short an estimator is bidding for the same candidate the practice wants, and the contractor can usually pay more.
Put a figure on why the practice should pay anyway.
Consider a $90 million healthcare project on which the practice holds the owner’s cost role. The contractor’s GMP arrives with general conditions ten weeks longer than the owner’s schedule supports, worth roughly $650,000, and a contingency two points above what the design stage warrants, worth $1.8 million. A consultant with the posture for the seat reconciles both down. One without it accepts the contractor’s lines with a note.
Together that is $2.45 million defended at a single reconciliation. Against that, the pay difference between a contractor estimator recruited into the seat at $135,000 and a proven owner-side consultant at $160,000 is $25,000 a year.
The illustrative figures price one reconciliation. The owner’s practice holds the role for the life of the project, and the change-order and pay-application reviews that follow are where the same posture earns its keep every month.
The CFMA literature on contractor financial reporting is worth the consultant’s time for the opposite reason a contractor reads it: it explains what the number on the other side of the table is built to protect. The GSA publishes the federal owner’s own cost-management expectations, which is a useful statement of what an institutional client assumes the seat does.
Which leaves the question of how the practice finds these people when it cannot say it is looking.
Can this search be run in the open?
Usually not, because the practice’s clients are watching. A posting tells every owner the practice serves that the person defending their budget is being replaced mid-project, and tells the contractors on those projects that the owner’s side is thin. A practice adding the seat for a new program finds the posting announces the pursuit.
Selah Talent Partners runs these as confidential executive search for mandates that cannot be publicly posted, and scopes the search as a consultancy hire rather than a contractor one, which is a different candidate profile from the same job title on the contractor side. The mechanics are set out in how a confidential construction search runs, and the owner’s-side symptoms that usually trigger the hire in when the owner’s rep sees a delivery team failing.
Selah works with contractors and construction consultancies across the United States on preconstruction and estimating, project and construction management, and cost and commercial management. Consultancies are clients in their own right, not only a place to source from. Candidates are never charged a fee at any stage.
This is not the search for a contractor adding an estimator to its own preconstruction department. That seat prices to win, and the contractor should hire for it accordingly. The seat described here earns its cost only where the consultant’s number is tested against someone else’s, which is the owner’s representative, the program manager and the cost-management practice. The seat above the cost consultant on a multi-project program is the program manager, and it is scoped the same way: an owner’s decisions, not a contractor’s work.
Hire the person who will say no to your client
The instinct on this hire is to buy the best contractor estimator the practice can afford.
Estimating skill is the entry ticket. The seat is decided by whether the candidate will tell the owner that the contractor’s number is wrong, and then tell the owner, three months later, that the owner’s own budget was wrong too. People who have done that describe reconciliation meetings. People who have not describe estimates.
Ask every candidate about the last number they refused to accept, and who they had to say it to. The answer tells you which side of the table they have sat on.
