Why buyout lists fall apart, and how to keep the estimate and the buyout in one place

Published 2026-08-17 · PreConstruct team

The estimate was tight. The job was won. Then someone opened a fresh spreadsheet, typed the buyout list from memory, and a line fell off. Nobody noticed until a sub asked who was doing it.

The pattern

1. The bid sheet is finished under deadline pressure and is the truth about the job.
2. After award, the buyout log is created separately — new file, new columns, retyped.
3. Anything that did not survive the retype is unowned scope.
4. It surfaces as a change order, a delay, or a margin hit.

The rule

The buyout list is the bid sheet. Not a copy of it. If every awarded line carries forward with its estimated amount, the only work left is assigning it, contracting it, and watching the delta.

What to watch

• Bought vs open, by division — so a whole trade cannot go quiet.
• Buyout total against estimate, live, not at month end.
• Lines with no assignee after the first two weeks.

In PreConstruct

Awarded scope moves from the bid sheet into buyout without re-entry, bought and open are tracked by division, and the budget tracker reads from buyout so committed cost is already there. See Buyout and Budget Tracker.
