DOT Bid Results Scraper – WSDOT Bid Tabulations & Caltrans Bid Results

Pull state Department of Transportation bid results into clean JSON, CSV or Excel. Each record includes the contract number, project title, bid opening date, engineer's estimate, every bidder with its bid amount and rank, the low bidder, and how far the low bid came in under or over the estimate. Built for heavy-civil contractors, estimators, materials suppliers, subcontractors, construction-data providers and bid-alert services.

Sources

Agency	What you get	Source
WSDOT (Washington)	Highway construction bid tabulations: engineer's estimate, all bidders with addresses and WSDOT contractor numbers, contract totals, % vs. estimate, award date	Official WSDOT bid tabulation PDFs (public)
Caltrans (California)	Weekly procurement and service contract bid results: contract number, description, district, bidders, small-business (SB) flag, bid amounts	dot.ca.gov weekly bid results pages

More DOTs are planned. TxDOT is not included because its current results are only available in an interactive Tableau dashboard.

Use cases

• Competitive intelligence: see who bid, what they bid and how often they win. Filter by bidderContains to track a competitor.
• Estimating: compare low bids with engineer's estimates to calibrate your pricing.
• Sales prospecting: materials suppliers and subcontractors can find the contractors who just won work.
• Market reports: analyze letting volume and bid spreads by region and month.
• Alerts: schedule weekly runs with sinceDate and push results to Slack, email or Google Sheets.

Notes

• WSDOT occasionally posts a bid tab as a scanned, image-only PDF. Those contracts are still returned, with parseStatus: "image-only-pdf" and the PDF link, so nothing is silently dropped.
• Caltrans results are preliminary, as posted by Caltrans, and may change after bid review.
• One result = one contract, with all of its bidders.

Use it as an MCP tool (Claude, Cursor, ChatGPT, any AI agent)

This Actor works as a tool in the Apify MCP server, so an AI agent can call it directly and you pay per result, the same as a normal run. Add this server URL to any MCP client:

https://mcp.apify.com/?tools=appetizing_horsefly/dot-bid-results

Sign in with your Apify account (or pass your Apify API token as a Bearer header). The agent reads the input fields above from the Actor's input schema. Example request to the agent: "Show Caltrans bid results since September 1 where a given contractor bid, with the low bid versus the engineer's estimate."
