It reveals where you landed against competitors, how the field priced individual items, and which line items tend to run high or low — making it one of the richest sources of competitive intelligence in public works. Estimators study past bid tabs to sharpen unit pricing and read the market before the next pursuit.
Because public bids are opened and read aloud, the tabulation is a matter of public record, and many agencies post it within days of opening. Compared against the engineer's estimate, a bid tab also shows whether the whole field came in high or low — a useful read on how aggressively competitors are chasing work and where your own pricing sits relative to the market. Nonlinear turns that history into signal: it analyzes historical bid tabs to surface pricing patterns, competitive positioning, and margin clues, so your next number is informed by what actually won — and lost — on comparable jobs.
