How to Use a Change Order Form in Construction

A change order form construction professionals use is a formal document that records any modifications to the original contract between a contractor and client. These modifications can include changes in project scope, adjustments to costs, or schedule revisions. Using a change order form ensures all parties agree on the changes before continuing work, which helps avoid disputes and confusion.

Why this comes up / what goes wrong

Construction business owners and accountants often face change orders due to unforeseen site conditions, client requests for additional work, or errors in the original plans. For example, a contractor may discover that the soil conditions require more extensive foundation work than initially planned. Without a proper change order form to document this change and adjust the contract price and timeline, the contractor risks not getting paid for extra work or facing scheduling conflicts.

Change orders are common in the construction industry because projects are complex and conditions can change. However, failing to document these changes properly can lead to disputes, unpaid invoices, or delays. A clear process and standardized change order form protect the interests of both contractors and clients.

Step-by-step

1. Identify the need for a change: Determine exactly what part of the original contract needs modification—scope, cost, or schedule.
2. Describe the change clearly: Provide a detailed description of the work or adjustment, including technical specifications and reasons for the change.
3. Estimate the cost impact: Calculate additional or reduced costs resulting from the change, including labor, materials, and overhead.
4. Assess schedule impact: Determine any changes to the project timeline or completion dates caused by the change.
5. Prepare the change order form: Use a standardized form containing project name, contract number, detailed change description, cost and schedule impacts, and approval signature lines.
6. Review internally: Have project managers and accountants verify the accuracy and completeness of the change order details.
7. Obtain client approval: Present the change order to the client for review and signature before starting the changed work.
8. Distribute copies: Provide signed copies to all relevant parties such as subcontractors, suppliers, and internal teams.
9. Update project records: Adjust budgets, schedules, and contracts to reflect the approved change order.
10. Monitor implementation: Track the work related to the change order to ensure it is completed as agreed.

Following these steps helps contractors and construction businesses manage changes effectively and avoid disputes. For more resources on managing construction projects, see Contractors and construction.

Example (fictional figures)

Consider a two-location dental practice in Columbus, Ohio, that contracted a builder for a $500,000 renovation scheduled to finish by 06/30/2026. Midway through, the client requests adding a sterilization room, increasing scope and cost.

• Original contract value: $500,000
• Additional work estimate: $50,000
• Additional time: 15 days

Cost calculation: $500,000 + $50,000 = $550,000

Schedule update: Original completion date: 06/30/2026 New completion date: 06/30/2026 + 15 days = 07/15/2026

The contractor prepares a change order form detailing the new sterilization room, the $50,000 cost increase, and the 15-day extension. The client reviews and signs the form on 04/15/2024. The contractor updates project schedules and budgets accordingly.

This example shows how clearly documenting changes and obtaining approvals protects both parties and keeps the project on track.

Common mistakes

• Not using a formal change order form: Prevent by always documenting changes with a standardized form.
• Proceeding without client approval: Prevent by requiring signatures before starting any changed work.
• Vague descriptions of changes: Prevent by clearly detailing scope, cost, and schedule impacts.
• Ignoring schedule impacts: Prevent by assessing and communicating timeline adjustments.
• Failing to update project records: Prevent by promptly revising budgets and schedules.
• Not distributing signed copies: Prevent by sharing the approved change order with all stakeholders.

Avoiding these mistakes maintains transparency and protects both contractor and client interests. For tips on managing communications and tasks efficiently, see WhatsApp and SMS CRM.
