CALICHE (CALICHE.IO)Manage supplier listing

Line-item Texas civil bid-price index built from public bid tabulations: 1,783,107 real contractor-submitted unit-price observations across 90,250 pay items, 254 counties (182 with full bid-tab depth), 3,100+ public agencies, and 7,518 named contractors — reconstructed as complete bid fields, meaning the winner AND every losing bidder priced line-for-line. Indexed nightly with a daily movers series on 90-day item price change. Prices are calibrated by agency type (developer/subdivision vs municipal spreads run to 51% on the same item). Two derived byproduct layers sit on top: (1) an entity index — per-contractor bid history, win rate, dollars won, and head-to-head rival records, with ~$5.9B of winning-bid value tracked over 24 months across 2,684 competitively bid jobs; (2) a plan-document corpus from the AI takeoff tool — engineer-labeled callouts read off scaled PDF/DXF plan sheets with each quantity pinned to its exact location on the drawing, i.e. plan-layout images paired with verified quantity ground truth.
