Case Studies and Results

Every price on this page is part of our live case study: each forecast was produced before bid day and scored against the published letting result. Nothing was generated or revised after the envelopes were opened. Across $4.8 Billion of DOT Lettings in Florida, Kansas, and Texas, we use Fold16 models, alongside our Research Center, to forecast every bid.
