Ask a senior estimator to price a job and you’ll usually get two answers.
The first is that of the archive: the take-off, the spreadsheet, the quantities extracted from the drawings.
The second one is taking longer to come out because they never wrote it. The engineer on this job always undersizes the elevations, so check the shafts before pricing the sleeves. The addenda for this GC arrive two days before bid day, so you’re holding off a bit until you see them. None of this is in the file, but it’s all in the number.
Think of them as two models of the same project. One lives in the software. The other lives in someone’s head. For 20 years, the industry has invested its money in the former, betting that good enough software would make the latter less important.
That bet was only half right. Software has made jobs faster to measure and easier to coordinate. It has not made the trial any less important. In any case, the more detailed the software, the more a job depends on someone knowing how to read it.
Where the money is filtered
A takeoff can get all the accounts right and still cost money. The drawings will not tell you that the specified cooler is 30 weeks old or that the only entrance to the site cannot take a concrete truck. The estimator who has been burned before will. No one else knows, because that lesson is in an old email, text, or phone call. When that estimator leaves, the lesson goes with them.
It doesn’t take a big foul to hurt. according to CFMA Financial Benchmarker 2025the typical contractor’s pretax margin was 6.7% in 2024. At that rate, $10 million in revenue returns about $670,000. A single 2% error can mean $200,000, almost a third. This is what the judgment of an experienced estimator quietly protects.
Experienced people have little time, not knowledge
Most estimating teams do not lack judgment. They lack time. Their best estimators spend much of the week measuring: counting fixtures, tracing duct runs and calculating square footage. No one hires a veteran estimator to count sprinkler heads, but that’s where a large part of their week is spent.
Take that time back and it can go where it matters: calling the supplier, reading the specs twice, and asking the scoping question no one else thought of.
What does this mean for how tools are built?
AI is moving to love fast. In the 2026 Construction contracting and business prospects from AGC and Sage, 61% of companies said they were using AI or planning to invest more in it. After clerical and administrative work, budgeting and pre-construction were the most common uses.
So what should the software do? the count That’s where it’s fast, and people are slow. Scope, risk and relationships belong to the people who understand them.
That’s the idea behind it Beam AIour take off pad. Read sets and full plan specifications and return amounts across trades, instantly in a self-service takeoff or, for complex deals, after our QA team reviews the AI work. We’re not trying to hand anyone a finished deal. The goal is a takeoff they can trust, so their hours are spent on calls only they can make.
Flooring and installation JBG is a good example. Manual takeoffs used to eat up much of the week that the team was missing projects. Now save up to two days per takeoff. This time is spent improving supplier prices, confirming that materials are available, and making sure each bid is competitive.
Knowledge is going out the door
This is the most difficult problem: many of the estimators who carry the second model are about to retire. Builders and associated contractors estimates that the industry needs 349,000 new workers by 2026, mostly to replace retirees. In the 2025 AGC-NCCER workforce survey92% of hiring companies reported difficulty filling open positions. Among the salaried positions, estimators were some of the hardest to fillnamed by 77% of companies looking for them. You can hire a new estimator. You can’t hire 20 years of knowing which fields always last.
Some of this can be saved if written while fresh. After each bid, a few notes about what drawings were missed, what quotes fell apart, and what the team would price differently give the next estimator something to build on.
This only happens when the estimators are not buried in takeoffs. Give them back the time and what they know will stop walking out the door.
