Professional practice, ethics and project management
What this domain tests
This domain tests judgement as much as knowledge: how you act when safety, cost, programme and client pressure conflict. Expect scenario questions on competence, conflicts of interest, documentation, escalation and handover.
Ethical framework
- The safety of the public and the user comes before commercial advantage. A gas engineer who signs off unverified work puts lives at risk.
- Work only within your competence and registration. If a task exceeds your experience, seek a competent colleague or decline.
- Declare conflicts of interest, reject inducements that could influence judgement, and keep client information confidential.
- Record decisions and the reasons for them. A contemporaneous note is the best defence when a decision is challenged.
- If you identify a serious safety breach, escalate it through the contractor, the client and, if necessary, the authority. Whistleblowing protection exists for protected disclosures.
Project management essentials
Define scope, interfaces and acceptance criteria early. Allocate risk to the party best able to control it. Coordinate gas works with building services, fire safety and electrical trades. Hold design and safety reviews before construction, not after. Manage changes through a formal change-control process. Commissioning and handover need as-built drawings, test records, O&M manuals and training.
Worked example
A contractor proposes reducing a commercial kitchen gas main from 50 mm to 32 mm to save cost and programme time. Your sizing check shows the smaller main would exceed the permitted pressure loss at peak demand and would starve the appliances. The contractor argues that the appliances rarely run together. You reject the change because design must satisfy the code's demand basis, not an optimistic operating assumption. You document the calculation, issue a non-conformance, and escalate to the client's project manager. The 50 mm main is reinstated, and the change is recorded in the design file.
Traps that cost marks
- Signing a completion certificate without witnessing tests or checking records.
- Accepting a gift or hospitality that creates a sense of obligation.
- Making a verbal safety decision without a written record.
- Allowing programme pressure to bypass a design review or change control.
- Handing over without as-built drawings, test records or operator training.
