Fabrication Estimating Assumptions and Exclusions Template
Record quote assumptions, exclusions, allowances, clarifications, evidence, owners, and customer-facing treatment before fabrication quote approval.
What this resource is for
An assumption fills an identified information gap for a defined purpose. An exclusion states work or responsibility that the offer does not include. Neither should be used to hide an incomplete review or contradict the stated base scope.
The template keeps internal reasoning, supporting evidence, clarification status, and approved customer-facing wording connected.
Designed for: Fabrication estimators and commercial reviewers making uncertainty visible before quote issue.

Fields and review points
How to use it
Describe the gap precisely
State what information is missing or uncertain and which part of the estimate or quote it affects.
Choose a reviewable treatment
Seek clarification, use an approved allowance, state an assumption, exclude the scope, or decline to price it. Record evidence and impact.
Align internal and customer-facing records
Make sure approved quote wording reflects the reviewed treatment and does not conflict with inclusions, options, or other exclusions.
Important review boundaries
- This template is not legal advice or a substitute for contract review.
- Avoid broad boilerplate that contradicts project-specific scope.
- Review resolved assumptions when new information arrives.
Questions about this resource
What is the difference between an assumption and an exclusion?
An assumption states a working basis used where information is incomplete. An exclusion states that identified work or responsibility is not included. The appropriate treatment depends on the RFQ and commercial review.
Should every internal assumption appear in the quote?
Customer-facing treatment should be reviewed. Material assumptions that affect price, scope, lead time, or responsibility should not remain hidden merely because they began as internal notes.
