Why the map the source of truth for the addendum log record needs its own control
The map the source of truth for the addendum log record matters because an estimate can look complete while the source, version, and approval path remain unclear. A reviewer should be able to reconstruct what changed, who confirmed it, and which assumption moved the cost.
For map the source of truth for the addendum log, the estimating support specialist can collect the source, compare versions, label exceptions, and prepare a dated next action. The chief estimator still decides whether the evidence is sufficient and whether the estimate can be released.
Where preparation ends and approval begins
The practical handoff is to keep map the source of truth for the addendum log preparation separate from approval. A clear role brief names the estimating support scope, the review owner, and the exception path. The quantity takeoff audit trail shows how evidence should survive a later review.
Use a published reference to test assumptions without treating it as a substitute for professional judgment. AACE recommended practices is a useful starting point for that review.
