As your team starts preparing bids for 2026, one thing is clear: your estimates will only ever be as good as the data behind them. And if that data is partial, outdated, or based on theoretical production rates, your 2026 margins are already at risk.
One of our clients in Florida learned this the hard way. When he compared his estimates to his actual 2025 field costs for the first time, he discovered 4.7% of margin gone, simply because no one had ever put those two columns side by side. According to FMI and KPMG, most major projects experience cost overruns or delays because the estimating assumptions never lined up with what actually happened in the field.
So the real question isn't "Do I have data?" It's: "Am I truly using my 2025 field data to build more accurate, more competitive, and more profitable bids for 2026?"
In theory, the more projects you complete, the sharper your estimates should get, and the stronger your margins should become. In reality? It rarely works out that way.
And when a company isn't getting more profitable over time, there's almost always one root cause: its estimates are never compared to what actually happened in the field.
Lining up your 2025 estimated costs against your actual costs is the starting point for any real improvement. The moment you do it, the gaps jump off the page.
According to the 2024 FMI Construction Outlook, contractors who regularly compare their estimates to their actuals improve margin predictability by 3 to 6 percent year over year. In other words: they take back control of their profitability.
"We realized our formwork crews hadn't hit the productivity levels we'd been estimating for four years. Our bids were living in 2020, our field was living in 2025."
The principle is simple: if you never compare your estimate to your actual, your projects won't teach you anything, and your margins won't improve.
Every project has variances. The dangerous ones are the patterns.
Three types of recurring variances hit margins the hardest:
Cost overruns almost always start with labor. According to FMI, a significant portion of budget errors comes down to one simple gap: what you think your crew can deliver versus what they actually deliver in the field.
These gaps tend to follow the same patterns:
Real example: A crew budgeted for 40 hours a week consistently logged 48 to 52 because of an access issue on-site. The result? $68,000 in unplanned labor over one season across three projects.
The lesson is universal: identify labor variances early, or you'll pay for them later.
ENR's 2024 Construction Cost Index reported a 3.8% average rise in material prices, but actual field usage is just as impactful:
If your 2025 quantities consistently exceed your estimate, your 2026 bids must reflect your real usage, not theoretical numbers.
In 2024, McKinsey estimated that contractors lose up to 25% of their equipment budget every year simply because machines stay on-site longer than needed, sit idle, or aren't allocated efficiently. Recurring issues:
"Keeping a dozer an extra day didn't feel like much, until we saw we did it 19 times last year." - Texas superintendent
Equipment overruns compound quietly, and hurt consistently. That's how field data protects your margins.
Collecting field data is one thing. Using it to build better bids is the real advantage.
Here's how top-performing contractors turn 2025 performance into 2026 predictability:
If your crews averaged 82 LF/day on storm sewer across four projects, stop estimating 110 LF/day. Real production = real margins.
Most labor overruns come from very concrete factors you can easily account for:
Build your 2026 bids around what actually happened in the field:
Don't forget seasonality: a compactor on saturated ground or a truck on icy roads won't perform the same way they do in mid-summer.
A 3–7% waste or loss factor is normal. Ignoring it costs you money every year. Your 2025 overrun patterns should define your 2026 quantity factors.
Your 2025 projects left you with a goldmine of concrete information:
When contractors base their bids on field data, three things happen:
Contractors who align estimates with real field performance recover 3–5% margin per project (FMI). On a $5M project, that's $150,000 to $250,000 of profit protected.
Not by lowering price, but by eliminating the "padding" used to cover uncertainty. When your numbers are precise, your price becomes strategic.
You know which scopes you excel at, and which ones quietly drain your margin. That clarity is worth more than any spreadsheet.
You don't need a full digital transformation to start. You just need a clear process:
If you're ready to make this process continuous instead of seasonal, platforms like Civalgo connect your field data directly to your estimates—so every project automatically improves the next one.
Margins don't vanish in one big event. They disappear through repeated assumptions that don't match your field reality.
Your crews have already produced a year's worth of insight. The contractors who use it will enter 2026 with more accurate bids, stronger margins, fewer surprises—and a major competitive advantage.
Your next profitable year is already written in your 2025 field data. You just need to read it.
