Who must approve all proposed methods of design, execution, materials, welding procedures, examination, and testing?

• A. The inspector or the piping engineer.
• B. The owner.
• C. The contractor.
• D. The QA/QC manager.

Answer: (A)

The authority to approve all proposed methods of design, execution, materials, welding procedures, examination, and testing rests with the inspector or the piping engineer. In practice, these roles are the ones with the technical responsibility to verify that everything planned for the project meets the applicable codes, standards, and project specifications. They review and approve the welding procedures (WPS), material specifications, inspection and testing plans (NDE methods, hydrotests, etc.), and any design or execution methods before work proceeds, ensuring conformity with safety and reliability requirements. The owner establishes overall objectives and contractual requirements but does not typically micromanage or authorize every technical method. The contractor implements the work according to approved procedures, and the QA/QC manager focuses on the quality management system and adherence to QA/QC procedures rather than serving as the final arbiter of every design or procedure.
