What is a change order in construction?

A change order in construction is a formal request to modify the original contract. This process is essential in construction management as it addresses necessary adjustments that arise during a project's lifecycle. Change orders can result from various factors, including unforeseen site conditions, design modifications, or scope alterations.

When a change order is issued, it typically details the nature of the proposed changes, the reasons for those changes, and any associated impacts on project cost or schedule. The change order must be agreed upon by all parties involved, ensuring clarity and mutual understanding before the changes are implemented. This formal documentation serves to protect both the contractor and the owner by providing an official record of alterations to the contract, helping to manage expectations and prevent disputes.
