BASIS OF COMPARISON

Same work.
Stated assumptions.

Read the full methodology ↗

The default sample uses the same agency, a confirmed work definition, compatible specifications and units, and the 36 months ending at the dataset snapshot. It uses original, nominal contractor bid prices. Unknown specifications and undocumented price adjustments cannot support a benchmark.

Each contract contributes one median, regardless of its number of bidders. At least five comparable contracts are needed for a line scenario. P25–P75 describes historical variation; it is not a confidence interval or a promise of your next bid price.

A transparent calculation

For a confirmed item, quantity × historical median unit price gives its median scenario. Matched rows are added into a Matched-items subtotal. Unmatched rows remain visible and are not priced automatically. No overhead, profit, tax, or mobilization is added.

Educational arithmetic only: 100 short tons × an illustrative $80 per short ton = $8,000. This example is not a historical observation or published benchmark. The downloadable example contains training inputs only; none are added to the historical database.
