Three framers bid the same house. One is far cheaper, because it priced 100 of the 120 sheets of sheathing and left out the house wrap and the hurricane ties. Comparing the totals as written compares different jobs.

The wall-framing takeoff has levelled bids for a few days; it now has its own page, bid-leveling-calculator.html, which needs no takeoff. You type a scope and each bidder's lines. A short quantity is priced up at that bidder's own unit price; a left-out line is priced at your typed price or the median of the other bids; a gap with neither is listed, never guessed.

On the made-up sample, Sub B is lowest as written at 3,340 and comes to 5,200 once levelled, which is above Sub A at 5,150. The figures are hand-computed in the test. The sample is invented, no real bid has been run through it, and the page ships no prices.
