The posted cost is not the historical cost

Every estimator knows the best data for the next bid is the job that just closed. Getting it out by element means reconciling the ledger against pay apps and the change order log, a week nobody has after closeout. So the posted figure gets reused, change orders and all.

One case on our Try page: a closed-out apartment job, cost by element. Building B's foundations looked twice as expensive as the others. Yesper traced it to a change order and one miscoded invoice; without them, $11.49/GSF. The total was 0.6% over estimate plus change orders; two elements carried almost all of it.

The cost database gets the reconciled figure and its area basis. The miscoded invoice turns up now instead of in the next bid. Same for any closed job, and the rest of the Try page: quantities from an IFC model, tenders against the scope split.
