A CWI is reviewing the Quality Control (QC) plan for a new bridge construction project. The plan states that all critical welds will undergo 100% radiographic testing (RT), and all non-critical welds will be visually inspected only. However, the applicable code (AWS D1.5 Bridge Welding Code) mandates that all groove welds in tension members, regardless of criticality designation, must undergo 100% RT. What is the CWI's professional obligation in this situation?
- AProceed with inspections according to the QC plan, but secretly perform additional RT on non-critical tension member welds.
- BDocument the discrepancy and notify project management, recommending revision of the QC plan to meet code requirements.
- CRequest a formal waiver from the client to modify the code requirements for economic reasons.
- DApprove the QC plan as written, as the project's internal plan takes precedence.
Show answer & explanationAnswer & explanation
Correct answer: B. Document the discrepancy and notify project management, recommending revision of the QC plan to meet code requirements.
A CWI's primary ethical and professional obligation is to ensure compliance with the applicable welding codes and standards. When a project's internal QC plan conflicts with a mandatory code requirement, the CWI must identify the discrepancy and escalate it to ensure the code is met, not bypassed.
Why the other options are wrong
- A. Secretly performing additional tests is unethical, unprofessional, and does not formally address the non-compliant QC plan.
- C. Requesting a waiver to bypass mandatory code requirements is unprofessional and typically not permissible for safety-critical structures like bridges.
- D. Approving a plan that violates code is a breach of professional ethics and responsibility.
Code vs. QC Plan Conflict
When a project's internal Quality Control (QC) plan deviates from or contradicts the mandatory requirements of an applicable welding code, the CWI's obligation is to ensure the code's requirements are met, requiring formal notification and resolution of the discrepancy.
- Codes override internal plans in case of conflict.
- CWI must uphold code compliance.
- Formal documentation and communication are essential.
Memory trick: Code is king, plan must sing its song.
