What Are Change Order Estimating Services?

A change order estimate is a detailed cost analysis prepared whenever the original construction contract requires modifications. These changes may result from design revisions, owner requests, unforeseen site conditions, code compliance updates, material substitutions, or additional scope of work.

Our change order estimates provide a transparent breakdown of all additional costs, allowing project stakeholders to evaluate pricing, negotiate fairly, and maintain control of project budgets.

When Are Change Orders Required?

Change orders are commonly prepared when:

Owner-requested design changes
Architectural or engineering revisions
Additional work outside the original scope
Unforeseen site conditions
Material substitutions
Building code updates
Permit revisions
Value engineering modifications
Schedule acceleration requirements
Contractor-requested scope adjustments

Whether you're adding, deleting, or modifying work, our estimating team provides accurate documentation to support every change.

What's Included in Our Change Order Estimates?

Every change order estimate is prepared using the latest project drawings, specifications, and contract documents.

Our Change Order Estimating Process

1. Review Project Documentation

We review the original contract documents, drawings, specifications, approved estimates, and the proposed changes to determine the revised project scope.

2. Perform Updated Quantity Takeoffs

Our estimators calculate all additional, revised, or omitted quantities using digital takeoff software to ensure every change is accurately measured.

3. Develop Revised Project Costs

We apply current California labor rates, material pricing, equipment costs, subcontractor quotations, and project-specific conditions to determine the true cost of each change.

4. Quality Review & Delivery

Every estimate undergoes an independent quality review before being delivered in an organized, easy-to-understand format suitable for owner review, contractor negotiations, or project documentation.

Why Accurate Change Order Estimates Matter

Poorly documented change orders often lead to payment disputes, delayed approvals, and reduced project profitability. A professionally prepared estimate provides clear documentation of additional costs, making it easier for owners, contractors, and project managers to review, negotiate, and approve changes with confidence.

Our detailed estimating approach helps ensure every project modification is accurately valued and properly supported.
