What this means
Unit prices are where highway bids are won or lost: the same item carries different prices by district, haul distance, quantity, and season, so the spread between the 25th and 75th percentiles is as useful as the median when pricing a line.
A bid tab is the tabulation TxDOT publishes after a letting: every bidder, every bid item, every unit price, next to the sealed engineer's estimate. This corpus holds every TxDOT letting that published bid tabs on data.texas.gov, loaded weekly and matched against the source month by month, so these are counts and rankings over the whole population, not a sample.
