Function 05 of 15Estimating
Estimating determines what a home should cost before anyone can decide what it should sell for. Everything financial downstream inherits its errors.
Estimating is the bridge between product development and construction. It produces the anticipated cost of each home, which pricing turns into a sale price, accounting measures actuals against, and purchasing buys to. An estimate that is wrong doesn't stay an estimating problem — it becomes a margin problem two quarters later, when nobody is looking at the estimate anymore.
The knowledge base grades estimates on four characteristics, COAT: Complete, Organized, Accurate and Timely. Organized carries more weight than builders expect — an estimate whose cost codes don't match the accounting chart cannot be checked against reality, so variance analysis quietly stops happening and the same error repeats on every home.
COAT
Complete, Organized, Accurate, Timely. An estimate that arrives after the decision was made scores zero on the last one.
Codes must match
If estimating and accounting don't share a chart, no one can ever tell you where you lost the money.
Variance is the product
The estimate's real output is the comparison to actuals. Without it you have a guess with a spreadsheet.
History beats intuition
Your last six homes are better data than any regional cost book — if the codes were clean.
Atlas in action
A rebuilt estimate, and the reason gross margin has been drifting for two years.
Cost code 03 has been carrying $17,800 of sitework since 2024.
The rebuilt estimate comes to $408,200, up $12,400 from the version in use. But the foundation overrun isn't a foundation problem: on all six recent homes, lot clearing and rough grading were invoiced against code 03 while the estimate carries them in code 02. Foundations look 14% over on every home and sitework looks under on every home — the two errors have been cancelling in the total, which is why nobody caught it in the margin report.
| Cost code | In use | Rebuilt | Δ |
|---|---|---|---|
| 02 · Sitework & grading | $21,400 | $39,200 | +$17,800 — miscoded |
| 03 · Concrete & foundation | $81,600 | $63,800 | −$17,800 |
| 06 · Framing & lumber | $138,900 | $146,300 | +$7,400 current bid |
| 09 · Drywall & finishes | $52,700 | $54,900 | +$2,200 |
| 15 · Mechanical | $46,800 | $49,600 | +$2,800 |
| Estimate total | $395,800 | $408,200 | +$12,400 |
Composite example. Two offsetting errors that net to nearly zero are the ones that survive longest — they never show up in a total.
The estimate is only as useful as the codes underneath it
Atlas reads your plan sets, your live bids and your job cost history at once, which is what it takes to catch an error that has been hiding inside a correct-looking total.
