Confirmed = pulled plans on this letting (revealed interest, from the agency portal). Likely = firms that bid OH pavement work in the last 3 years, ranked by where and how recently they bid it — firms most active in this project’s county and ODOT district rank first. Win rate is historical — the share of bids that firm entered and won, not a prediction of this letting.

How to read this. Plan‑pull counts come straight from agency portals. Patterns and confidence scores are derived from comparable lettings (same county, same category, three‑year basis). Confidence is a calibration of past correctness on signals of this shape — not a guarantee of this bid’s outcome. We never round up. More on what Cassandri does →
