Change Order Estimating Services

Documented estimating support for revised drawings, directives, field changes, and other scope modifications requiring clear quantity and cost review.

Price Scope Changes With Clear Quantity & Cost Backup

When project scope changes, we compare the available baseline information with the revised documents or directive, isolate the affected work, and develop the applicable quantity and cost impact. The resulting estimate keeps changed scope, pricing assumptions, and supporting information organized for contractor review.

How This Service Works

01

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.

02

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.

03

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.

Documented Change Pricing for Contractor Review

Each change estimate connects the revised scope to measurable quantities, cost impacts, and documented assumptions so your team has a clearer basis for reviewing and presenting the change.

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.

Estimating Deliverables Built for Real Construction Workflows

Depending on the selected service and confirmed project scope, deliverables may include detailed cost estimates, organized quantity takeoffs, marked-up drawings, editable spreadsheets, and scope documentation for contractor and project-team review.

Common Deliverables & Report Formats
From takeoffs to final reports, deliverables are structured for clear scope review, pricing review, bid preparation, and preconstruction planning.

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.
