Which of the following actions is a CO approval item in regards to engineering dept?

• A. Repainting a component
• B. Starting major equipment
• C. Training
• D. Replacing a light bulb

Answer: (B)

CO approvals deal with changes to the project or maintenance plan that affect scope, cost, schedule, or safety. Starting major equipment is a significant action that can alter the project baseline—it's about bringing in and commissioning new assets, which has wide-reaching implications for procurement, safety, testing, and documentation. Because of that, it requires formal authorization through a Change Order process.

Routine tasks like repainting a component or replacing a light bulb don’t change the overall scope or cost of the project, and training, unless tied to a new procedure or scope change, is part of normal operations rather than a formal change. So they don’t typically need CO approval.
