How Professional General Contractors Manage Change Orders

During your bathroom renovation, you ask about replacing the planned bathtub with a walk-in shower. Before proceeding with this type of change, general contractors will review what is needed and provide an updated price.

In this guide, Vatter Construction explains how change order management works. That way, homeowners can understand why it is important to review proposed adjustments and approve clear terms before additional work begins.

When Is a Change Order Needed?

The construction change order process formalizes agreed revisions through a written amendment to your original contract. It applies when work falls outside the approved scope or existing terms need adjusting.

Project scope modifications can range from relocating a wall at your request to addressing concealed damage found during demolition. Additional work can raise costs, while omitted items could result in a credit. 

Set Ground Rules Before the Project Starts

Your original contract should explain how to request revisions and identify who can approve them. Agree on a communication channel and expected response time before construction begins so neither party has to guess what happens next.

Understanding how changes are approved is one of the essential steps to take before hiring a contractor. Ask prospective companies to explain their process and include it in the agreement.

Put the Requested Change in Writing

Effective change order management turns verbal requests into written proposals that everyone can review. You might include these key details:

  • Scope description: Identify the affected work and explain how it differs from the approved plans.

  • Reason for the change: State whether the request reflects your preference or an unexpected site condition.

  • Supporting information: Attach relevant photographs or marked drawings showing the affected area.

Change order documentation provides the basis for accurate pricing and informed approval. The contractor may assign a unique reference number and date for easy identification.

Determine the Cost of a Change Order

Your contractor calculates construction cost adjustments by comparing the proposal with work already covered under the original agreement. The estimate should include:

  • Labor: Account for added hours or changes to subcontractor tasks.

  • Materials: Include updated quantities and applicable delivery or return charges.

  • Credits: Deduct the value of removed work or less expensive selections.

  • Pricing: Apply overhead and markup according to the agreed method.

A completed proposal should show the net adjustment and revised contract total, making its full financial impact clear.

Handle Disputed Change Order Requests

Change order management may include disputes, and often involves conflicting interpretations of the contract. Homeowners may question whether an item belongs in the original scope, while contractors may argue that circumstances justify additional compensation. Before treating the request as accepted, both sides should compare their positions with the signed agreement and relevant project records.

Separate undisputed work from the contested item where practical, rather than assuming the entire project must stop. Ask for a written explanation of the contractor’s position and provide specific reasons for any objection. If discussions stall, consult the dispute resolution provisions established in the contract.

Coordinate Change Requests From Subcontractors

A subcontractor may submit a request for work outside its assigned package. The general contractor will check whether it reflects an existing obligation or a genuine addition.

Overlapping requests from different trades need particular attention. For example, relocating plumbing may involve pipework and repairs to surrounding finishes. Reviewing those submissions together helps identify duplicated charges or missing responsibilities.

Secure Approval Before Revised Work Begins

The change order approval process gives you an opportunity to review pricing and scheduling terms with your contractor. Resolve outstanding questions so authorized parties can record their agreement.

Discussing a request does not grant permission to proceed, even when action feels urgent. Follow the contract’s established procedure before beginning the revised work.

Move Forward With the Approved Change

Change order management continues after approval by ensuring everyone receives the updated instructions. Your contractor distributes current drawings and checks completed work against the agreed requirements.

Project schedule management coordinates material deliveries and subcontractor tasks around existing commitments. Additional work does not automatically delay completion; the impact depends on sequencing and availability.
