📈

Construction Cost Trend Analysis

Prices aren't static. The engine weights recent data heavier so your estimates reflect where the market is heading, not where it's been.

Online
🔬

Estimate Accuracy Backtesting

Run the engine against past lettings and compare its number to the bids that actually came in. Backtesting is for calibration, not prediction. You see how close the engine has been on this kind of work in this region, so when you face a live bid you know how much weight to put on it.

Encrypted Bid Estimate Vault

Your saved construction cost estimates are protected with AES-256 bit encryption. Nobody else, not even us, can view your bid numbers or pricing data.

DOTestimate has been serving highway construction professionals since 2004. Over two decades operating in this market, distilled into the tools you actually need.

A decade of DOT bid history. Not a 12‑month snapshot.

Most DOT bid tabulation services give you up to a single year of history per state. That is a snapshot. DOTestimate gives you the market.

Price escalation trends

A year of bid tabs cannot show you escalation. Ten years can. Watch HMA, PCC, aggregate base, and structural steel prices arc through real market cycles, not a single snapshot.

Outlier detection

With one year of data, you cannot tell a market-rate bid from an anomaly. With a decade, the distribution is real. Outliers stand out instead of distorting your average.

Contractor pricing patterns

Bidding behavior plays out across years, not months. Multi-year contractor intelligence reveals win rates, repeat behavior, geographic specialization, and pricing posture against the market.

Defensible engineer's estimates

Every line in an engineer's estimate needs a number you can defend. A historical record going back a decade is the difference between “market rate” and “guess.”

Multi-state in one account

Search Illinois, Iowa, Wisconsin, Michigan, Kansas, Missouri, Minnesota, Georgia and more from a single account. Compare regional unit prices for the same pay item across borders.

Real demand cycles

For materials suppliers, equity analysts, and infrastructure investors, demand cycles are the whole story. A decade of DOT lettings reveals what one year cannot: capacity, consolidation, and momentum.

DOTestimate has been collecting and indexing DOT bid tabulations since 2004. That history is searchable from day one. No data window to expire. No archive paywall. No annual contract. Start a free trial and see what a decade of DOT bid history actually looks like.

One DOT bid history dataset. Every side of the market.

Engineers, owner-side estimators and consulting design firms use DOT bid history to build engineer's estimates for owners and agencies. Contractors use DOT analytics to win the next DOT bid; subcontractors use DOT letting analysis to find their next prime. State DOTs and the FHWA use the DOT Profiler to understand the procurement market behind every DOT letting. Equity analysts, infrastructure investors and materials suppliers use the DOT data for highway construction market research.
