Map every alternate to scope
Create one record for each alternate using the exact bid-form label. Identify affected drawings, specifications, estimate codes, quotes, allowances, and schedule assumptions. Clarify whether the alternate adds, deducts, or replaces base work.
Do not assume a deductive alternate equals the base cost removed. It may change temporary work, productivity, supervision, or purchasing conditions. Use the alternate pricing review as a related estimate control.
Calculate the net effect
Show removed cost, added cost, quote differences, indirect effects, and applicable markups as separate lines. The estimate alternate pricing review provides a useful control for checking this net calculation.
The Procore construction glossary offers general terminology references. The project bid form and procurement instructions govern how each alternate must be submitted.
| Review field | Required record |
|---|---|
| Alternate | Exact bid-form label |
| Removed | Base-scope cost removed |
| Added | Replacement and indirect cost |
| Submitted | Approved net value and sign |
Match the final bid form
Compare the approved alternate value against the estimate summary and the actual bid-form field. Confirm signs, rounding, and whether the owner requests a lump sum or separate values.
Keep a copy of the completed form with the approval record. Use the bid form estimate crosscheck before submission so a correct estimate is not lost to a transcription mistake.
