What to check before measurement
- Reconcile opening counts by elevation and schedule.
- Check formulas, units and repeated-floor exceptions independently.
- Review all unresolved glass, anchor, hardware and perimeter interfaces.
A practical bid example
A total can reconcile mathematically while omitting an entire elevation. Compare register coverage with the drawing index as well as checking spreadsheet sums.
What the reviewer should receive
A review record identifying the reviewer, drawing cut-off, corrections and outstanding qualifications.
Keep revisions and responsibility visible
Record the source sheet, detail or specification and revision beside the affected item. When information conflicts, leave the affected quantity or price pending and attach a question for the authorised project contact. A blank or unresolved entry must never be silently converted into zero.
Before issuing a revised package, identify changed, removed and added items. Separate measurement corrections from new scope and keep the previous output marked as superseded. The contractor retains final tender review and approval.
