The Unpermitted Structural Modification
You are a structural engineer employed by a mid-sized consulting firm. A long-standing client, a property developer, has submitted a permit application for a six-storey residential building. During your review of the drawings, you notice that the lateral load-resisting system shown differs from the one you originally designed and sealed. Specifically, the number of shear walls has been reduced from eight to five, and two of the remaining walls have been relocated. The client claims the changes were made to 'optimize costs' and that a junior engineer in your firm verbally approved them. You have no record of this approval, and the junior engineer is on vacation. The client is pressing you to sign off on the revised drawings because the permit submission deadline is in three days. If you refuse, the client threatens to take the project to another firm. Your manager is aware of the situation but has not given explicit direction, stating only that 'we need to keep the client happy.'

Your paramount obligation is to protect the public interest, which includes the safety and structural integrity of the building. The changes to the lateral load-resisting system are significant and could compromise the building's ability to withstand seismic or wind loads. You must not sign off on drawings you did not design or verify.
Steps:
- Verify the changes: Immediately review the revised drawings and perform a preliminary analysis to determine if the reduced shear walls are adequate. If they are not, you have clear evidence to present to the client and your manager.
- Document everything: Record all communications, including the client's request, the junior engineer's alleged approval, and your manager's comment. This protects you and provides a clear record.
- Communicate with the client: Explain that you cannot seal drawings that deviate from your design without a proper engineering review. Offer to perform the review quickly, but be clear that you will not sign off unless the design is safe. Do not be swayed by the threat of losing the client; your professional seal is a matter of public safety.
- Escalate internally: Speak with your manager directly, presenting the technical facts and your ethical obligations. If the manager insists on signing off without proper review, you must refuse and consider reporting the matter to your professional association.
- Consult your professional association: If the situation escalates, seek guidance from your regulator. Many associations have advisory services for exactly this kind of pressure.
Key principle: Never seal work you did not prepare or directly supervise. The client's deadline does not override your duty to the public.
2. How should you handle the junior engineer's alleged verbal approval? What are the implications for your firm's quality control processes?
Read the worked answer
The alleged verbal approval by a junior engineer is a serious concern. Verbal approvals are not acceptable for design changes; all modifications must be documented and approved by the engineer of record.
Actions:
- Investigate: Once the junior engineer returns, discuss the matter privately. Determine what was said and whether any analysis was performed. If the junior engineer did approve changes without authority, this is a breach of protocol and must be addressed.
- Review firm policies: The incident reveals a weakness in your firm's quality control. There should be a formal process for design changes, including written requests, analysis, and sign-off by the engineer of record. Implement a policy that no verbal approvals are binding and that all changes must be documented.
- Training: Ensure all staff understand the importance of documented approvals and the limits of their authority.
- Consider reporting: If the junior engineer's actions were negligent, you may have a duty to report to your professional association, depending on your jurisdiction's rules. At minimum, address it internally with appropriate discipline or training.
Implications: The firm must strengthen its quality control to prevent similar issues. This includes clear communication channels, written change orders, and a culture where junior staff feel comfortable questioning but not overstepping their authority.
