Public owners often publish a bid tab after the bid opening. It shows each general contractor's base bid and alternates. General contractors keep their own tabs for each trade.
Example: a general contractor's tab for the flooring trade lists four bidders. It shows each base price and the adjustments made during leveling.
Use public bid tabs to learn how your market prices work. They show who bid and how far apart the numbers were. Ask the general contractor where your number landed after the bid. Many will tell you your rank.
