Construction change order form template 

Break down all additional expenses by separating labor and material costs. Research current market prices for materials, consult with suppliers for quotes, and calculate labor hours based on similar past work. Include any equipment rental costs, permit fees, and a reasonable contingency percentage. Document your calculation method to justify the figures when discussing with clients.

A valid construction change order requires signatures from both the authorized contractor representative and the property owner or client. Some projects may also require architect or engineer approval depending on contract terms. Make sure all required parties review the complete document including scope changes, cost implications, and timeline adjustments before signing to prevent future disputes.

Always submit a formal change order when modifications affect project scope, cost, or timeline. Even seemingly minor changes should be documented if they impact the original contract terms. Verbal agreements often lead to disputes and payment issues later. Submit the change order immediately when you discover the need for modification and before performing any additional work.

Your work description should be specific enough that someone unfamiliar with the project could understand exactly what changes will be made. Include precise locations, dimensions, materials to be used, and techniques to be employed. Avoid vague language like “repair as needed” and instead specify “replace damaged drywall in northeast corner of room 203 with 1/2-inch moisture-resistant gypsum board.”
