What is the primary purpose of a change order in construction management?

The primary purpose of a change order in construction management is to modify the original contract. Change orders are essential documents that officially alter the terms of a construction contract. They may involve changes to the scope of work, adjustments in project costs, or alterations in project timelines. When unexpected issues arise or modifications are requested by the client or contractor, a change order provides a necessary legal framework to ensure that all parties agree to the changes made. This helps maintain clarity and accountability throughout the construction process, ensuring that the project can move forward efficiently and according to updated specifications.

The other options focus on aspects of project management that do not directly pertain to the modification of the contract. For instance, while formal complaints and communication of delays are essential parts of project management, they do not fundamentally alter the contract itself. Similarly, scheduling inspections is a normal part of the construction process but does not include changes to the original contract terms covered by a change order. Thus, the correct answer highlights the specific purpose of a change order in ensuring that the project adheres to the agreed-upon terms despite modifications.
