Professional ethics, sustainability and the engineer's role in society
Ethics and sustainability questions test judgement under pressure. The examiner wants to see that public safety, competence and integrity override commercial convenience, and that sustainability is treated as an engineering constraint rather than a slogan. Hong Kong engineers are also subject to the Prevention of Bribery Ordinance and the HKIE code of conduct.
Core rules and concepts
- Public safety first: if a system is unsafe or unverified, do not certify it. Record your advice and escalate through the responsible engineer, client and, if necessary, the authority.
- Competence: work within your expertise; obtain specialist review where needed; keep records of assumptions and checks.
- Integrity: avoid conflicts of interest, refuse improper gifts, keep confidential information, and do not misrepresent qualifications or test results.
- Sustainability: use life-cycle thinking - energy, carbon, water, waste, refrigerant global warming potential, maintainability and end-of-life. BEEO, BEAM Plus and carbon targets are tools, not substitutes for engineering judgement.
- Whistleblowing: use internal channels first where safe; serious risks to life or environment may justify external disclosure.
Worked example
A client asks you to certify a new chilling system as complete so the building can open, although integrated tests and fire-mode tests are incomplete. Reasoning: certification is a statement of professional judgement, not a commercial favour. Incomplete integrated tests leave unknown risks: failure transfer, controls, fire damper interlocks and power failure response. You should refuse certification, issue a written list of outstanding items, propose a phased handover with temporary measures only if safe and approved, and escalate if pressure continues. The short-term delay is outweighed by public safety and the risk of a false record.
Traps that cost marks
- Treating legality as sufficient ethics.
- Accepting a gift that could influence a decision.
- Using confidentiality to hide a serious safety risk.
- Claiming sustainability without measurement or verification.
- Signing off work you did not check.
