Name the baseline set
Record the baseline drawing set and issue date. Keep item names and location codes stable.
Store the takeoff version beside its document identifier. For takeoff revision control, use this related guide as context while keeping the current project documents in control.
Find changed documents
Read addendum narratives, clouds, and sheet indexes together. Mark affected scope before editing quantities. Classify sheets as new, revised, replaced, or voided.
Revise with history
Preserve the prior quantity before changing it. Separate plan changes from estimator corrections.
Revisit related areas, lengths, counts, and volumes. When reviewing takeoff revision control, consult AACE International for cost-engineering context, then apply it through the contractor’s own standards.
| Field | Record | Decision check |
|---|---|---|
| Revision identifier | Record the revision identifier used for takeoff revision control. | Confirm the entry against its cited source and assigned reviewer. |
| Document change | Record the document change used for takeoff revision control. | Confirm the entry against its cited source and assigned reviewer. |
| Prior quantity | Record the prior quantity used for takeoff revision control. | Confirm the entry against its cited source and assigned reviewer. |
| Current quantity | Record the current quantity used for takeoff revision control. | Confirm the entry against its cited source and assigned reviewer. |
| Reviewer and status | Record the reviewer and status used for takeoff revision control. | Confirm the entry against its cited source and assigned reviewer. |
Reconcile downstream pricing
Use one controlled export into pricing. Compare work-package totals before and after revision. Refresh alternates that use changed quantities.
Lock the final quantities
Freeze the final set at the internal deadline. Confirm every estimate section uses one revision.
Include the revision summary in handoff. For recurring takeoff revision control records, an estimating support role can maintain inputs while final approval stays with the contractor.
