Documented estimating support for revised drawings, directives, field changes, and other scope modifications requiring clear quantity and cost review.
- Service Overview
Price Scope Changes With Clear Quantity & Cost Backup
How This Service Works
Baseline & Change Scope Review
We review the available original scope together with revised drawings, directives, RFIs, field information, or other change documentation to identify what has been added, deleted, or modified.
Delta Quantity & Cost Build-Up
Changed quantities are measured and the agreed material, labor, equipment, subcontractor, or other applicable cost basis is applied to the affected scope, including agreed markups where applicable.
Documented Change Order Estimate
A structured change estimate is delivered showing the affected scope, quantities, cost impact, assumptions, exclusions, and supporting references available for contractor review.
Key Challenges Contractors Face
- Change pricing is harder to review when the changed scope is not tied clearly to the baseline documents or directive.
- Added, deleted, and modified work can be missed or double-counted when the scope delta is not isolated systematically.
- Delays in quantifying and documenting changes can slow internal approvals, owner/GC review, and project cost control.


- Our Value
Documented Change Pricing for Contractor Review
Clear Backup for Each Scope Change
Changed quantities, applicable cost components, and available source references are organized together so the commercial impact is easier to review and explain.

- FAQs
Frequently Asked Questions
Answers to the questions contractors most often ask before requesting an estimate.
What is included in a change order estimate?
Depending on the confirmed scope, a change order estimate may include the affected quantities, material costs, labor costs, equipment or subcontractor costs, agreed markups, assumptions, exclusions, and references to the available documents supporting the change.
How do you determine the cost impact of a scope change?
We compare the available baseline scope with the revised information, identify the added, deleted, or modified work, measure the affected quantities, and apply the agreed pricing basis to the resulting change.
Can you price both added and deleted work?
Yes. Where the project documentation supports it, additions and deletions can be separated so the contractor can see the individual and net cost effect of the change.
Can you use our contract rates, vendor quotes, or agreed markups?
Yes. Client-provided contract rates, supplier or subcontractor quotations, agreed markups, or other confirmed pricing inputs can be incorporated where they form part of the approved estimating basis.
Can a change order estimate support owner or GC review?
Yes. The estimate can provide structured quantity and cost backup for commercial review. It does not constitute legal advice, claim certification, or a determination of contractual entitlement.
