What is a construction change order?  

A construction change order is a document that updates the original construction contract when the scope of work, cost, or project timeline needs to change. It explains what part of the project scope is being revised, why the change is necessary, and how it affects the schedule and project costs. All parties sign it before work continues so the update is captured in writing.

Common challenges with change order approvals

Change order approvals often slow down projects because teams struggle to keep everyone aligned on the process and communication channels.

Common issues include:

• Missing signatures that affect the project timeline.
• Verbal approvals that aren't documented properly.
• Multiple revisions without version control which makes it difficult to confirm the final approved terms.
• Email attachments create delays when supervisors or owners are unavailable.
• Lost paper forms or photos taken in the field that never make it back to the office.
• Disputes over what work was “approved” when scope or changes in project budget are unclear.
• Slow communication between teams on site and teams in the office.

Understanding what a complete change order includes helps reduce back‑and‑forth and avoid disputes over the original scope. Clear review and approval processes also help teams keep the project management workflow moving without delays.

Typical elements of a construction change order

While projects may differ, all change orders follow a similar structure:

1. Change description
   Details of added, removed, or revised work may adjust the contract scope.
2. Cost impact
   Changes in labor costs, material costs, and a new proposed contract price.
3. Schedule impact
   Updates to start or completion dates that may shift the project schedule or modify the contract time.
4. Reason for change
   An explanation of why a change in the initial contract is needed.
5. Supporting documentation
   Attachments like updated construction documents or diagrams outlining accurate cost estimation.
6. Approval terms
   Notes or conditions that align with the contract terms or clarify the changes on the original agreement.
7. Contractor/owner signatures
   Confirmation that both the contractor and the project owner agree on the update.
8. Change order number
   A unique contract number identifier that helps teams track versions and maintain clean contract documents.

A clear change order layout helps both the sender and recipient review the update quickly and move through the final approval process on time.

Approve construction change orders on site  

Teams often rely on mobile apps when updates need to be signed from the construction site, ensuring everyone stays on the same page without returning to the office.

With Xodo Sign mobile features, you can:

• Open change orders on your phone or tablet
• Measure distances and areas
• Add notes or markups
• Sign and request signatures from others
• Share signed documents with your project team
• Send change orders if you're the one issuing revisions

These options help prevent delays when work changes require quick on‑site confirmation. To use Xodo Sign on mobile, download the Xodo app for iOS or Android.

Compliance and documentation best practices

Good documentation habits make change order management easier and protect teams during audits or disputes.

To keep your change order approvals audit‑ready:

• Store all signed change orders with the master contract
• Keep a naming convention (e.g. CO‑005‑Masonry)
• Export PDF reports for turnover packages or regulatory audits
• Use audit trails during compliance reviews
• Maintain version control for mid‑project updates

These habits support accurate records throughout the construction process.
