What can trigger a change order in a construction project?

A change order in a construction project is a formal document that modifies the original construction agreement. One common trigger for a change order is a client's or owner's request for upgrades or modifications. This scenario often arises when a client desires enhancements to the original plans, whether it's an increase in building features, changes in materials, or other specified alterations not originally included in the contract. These modifications can affect the scope, cost, and timeline of a project, necessitating the formal change order process to officially document and approve the changes.

In contrast, while unfavorable weather conditions and delays in material supply can impact schedules and costs, they typically fall under risk management or contract provisions related to unforeseen circumstances rather than triggering a change order due to direct requests. Completing the project ahead of schedule, while beneficial, does not inherently require a change order as the original terms of the contract may still be satisfied despite the expedited timeline. Thus, additional requests for changes from the client are the primary reason for issuing a change order, making that the most appropriate choice.
