Which roles are authorized to approve proposed design, execution, materials, welding procedures, examination, and testing?

• A. The inspector and the piping engineer.
• B. The owner and contractor.
• C. The QA manager and safety officer.
• D. The welding supervisor and inspector.

Answer: (A)

Authority to approve proposed design, execution, materials, welding procedures, examination, and testing comes from the combination of engineering design judgment and independent verification. The piping engineer is the design authority who evaluates and approves the design basis, material selections, and welding procedures—these decisions determine the system’s integrity and compliance with codes and project specs. The inspector provides the independent verification that these approvals are implemented correctly in the field, ensuring that execution, examination, and testing align with API 570 requirements and the project. Together, they cover both the engineering rationale and the assurance that field work meets the necessary standards. Other options miss this balance: owners and contractors don’t typically provide technical approvals for design and procedures; a QA manager and safety officer focus on quality systems and safety rather than engineering design and field approval; a welding supervisor and inspector handle execution and inspection, but the design and materials approvals come from the engineering design authority, with verification by the inspector.
