Site Supervision, Safety, Contract Administration and Professional Liability
This domain tests the boundary between the professional's statutory and contractual duties. Scenario questions typically place you between a contractor pressing for a variation, a client pressing for a certificate, and a site condition that is not what the drawings assumed. The marking turns on authority: who may instruct, who must inspect, who must record.
Supervision
The Code of Practice for Site Supervision sets out the supervision plan approach, with technically competent persons assigned to defined supervision levels, hold points and inspection frequencies for each stage of the works. Supervision is a recorded activity: inspection sheets, checklists against approved plans and specifications, photographs with dates, and prompt reporting of deviations. Certification without inspection is the single most damaging admission a professional can make. Where supervision reveals non-compliance, the route is notification to the Building Authority and to the contract administrator, not a quiet instruction to the contractor.
Safety and contract administration
Site safety duties sit under the Factories and Industrial Undertakings Ordinance (Cap. 59) and its Construction Sites (Safety) Regulations, and under the Occupational Safety and Health Ordinance (Cap. 509). Safety is not delegated away by the professional's contract, and a surveyor who sees an unsafe practice on site has a duty to act and record. Under the contract, the contract administrator issues instructions, valuations, certificates, extension of time and loss and expense decisions. A surveyor or AP who directs the contractor to change the works may be creating a variation outside authority. The correct sequence is: record the issue, notify the contract administrator, obtain a written instruction.
Liability
Professionals face concurrent liability in contract and in tort, with a six-year limitation period for most claims under the Limitation Ordinance (Cap. 347) and twelve years for deeds. Professional indemnity insurance is usually written on a claims-made basis, so cover depends on the policy in force when the claim is notified, not when the work was done. Contributory negligence by the client or contractor reduces damages, and clear records are the strongest mitigation.
Worked example
A contractor asks the AP on site to approve a cheaper rebar detail 'because the engineer is unavailable'. The AP has no authority to vary the design and no authority to instruct under the contract. The correct action: refuse, record the request and the reason, notify the contract administrator and the registered structural engineer in writing, and continue to supervise against the approved plans until a written instruction or revised approval is received.
Traps that cost marks
Certifying work not inspected. Accepting contractor test results without witnessing. Issuing instructions outside your contract authority. Assuming the contractor's insurance protects the professional. Failing to record verbal instructions.
Case-based Professional Judgement and Report Writing
This domain tests whether you can turn evidence into a defensible written conclusion. Markers look for structure, stated limitations, separation of fact from opinion, and the discipline to say what the evidence does not support. Reports written as advocacy lose marks even when the conclusion is right.
Report architecture
A professional report should open with purpose, scope and instructions, then identify the documents, plans and site evidence relied on. Methodology follows, then observations, then analysis, then opinion. Limitations and assumptions belong in the body, not hidden in an appendix. Sign off with name, qualification, date and a declaration of independence where the report may be used in a dispute. Appendices carry the raw evidence: plans, photographs, computation sheets, calibration certificates.
Expert reports
Where the report may go to court, arbitration or a tribunal, the expert's overriding duty is to the tribunal, not the instructing party. That means stating the facts and assumptions on which the opinion rests, considering alternative explanations, distinguishing measurement from interpretation, and being willing to give evidence that does not suit the client. Mixing the roles of advocate and expert is a classic failure and is usually penalised twice: for the conclusion and for the conduct.
Language and evidence discipline
- Define the datum, epoch, projection and coordinate system for every figure quoted.
- Attach an uncertainty to every measured conclusion and explain how it was derived.
- Use consistent units, and state whether levels are mPD.
- Separate 'observed', 'inferred' and 'recommended' with explicit wording.
- Keep contemporaneous field notes and photographs with metadata; they are the foundation of the report.
Worked example
A boundary dispute report where the lease plan is ambiguous. A weak report states that the boundary 'is' at a particular line. A strong report sets out the lease plan dimensions, the field evidence, the reconstructed historic alignment and the uncertainty, then concludes that on the evidence the boundary most probably lies at a stated line, with an identified alternative if a particular stone is accepted as original. It then states that the determination of the legal boundary between the parties is a matter for the tribunal.
Traps that cost marks
Giving legal opinions on title or rights. Omitting limitations and assumptions. Presenting unverified assistant data as your own observation. Writing advocacy. Quoting measurements without datum or uncertainty. Leaving the report undated and unsigned.
