1.5 The Oral Interview and Project Defence
Key Takeaways
- The oral interview examines the Folio you submitted; it tests whether you personally executed and understood the work, not whether you can recite theory.
- Examiners typically open at a join in the evidence chain - a value on the plan traced back to the computation and then to the field book entry.
- Where a genuine error is found, the correct response is to acknowledge it, explain its cause, quantify its effect and state the corrective action.
- Ethical and legal scenarios are standard: encroachment discovered mid-survey, a client asking for a boundary to be shifted, work previously done by another surveyor.
- Answers must map to authority - the SURCON Act, the Survey Co-ordination Act, the State Survey Law and Regulations, and the Land Use Act - not to personal preference.
1.5 The Oral Interview and Project Defence
The Folio is assessed on paper first. The oral interview then asks a different question: did this candidate do this work, and does this candidate understand it?
1. What the panel is testing
Three things, and they are not equally weighted:
- Authenticity. Can you account for the work in detail no one could fake - the state of the ground, why a station was sited where it was, what went wrong on the second day?
- Understanding. Can you explain why a procedure was used, not merely that it was? "We ran a closed traverse" is description. "We closed the traverse because regulation 4 requires connecting traverses normally to be closed circuits, and where closure is impossible the lengths must be double-chained in opposite directions and a check azimuth observed on the last leg" is understanding.
- Professional judgement. Given a situation with no clean answer, do you reason from duty and authority?
2. How the questioning usually develops
Examiners work from the documents in front of them, and the standard opening move is to pick a value and walk it backwards:
"This bearing on your plan - show me where it comes from."
You point to the computation. "And this angle in the computation?" You point to the field book page. "And what was the tape error on that date?" You point to the standardisation entry.
A candidate who can do that in ten seconds has effectively passed the authenticity test, and the interview moves on to substance. A candidate who fumbles has invited the panel to keep pulling that thread.
Prepare by rehearsing exactly this traverse of your own documents for two or three values per project, chosen from different parts of the work: a boundary bearing, an adjusted coordinate, a computed area.
3. Handling an error discovered in the room
Errors are found. What is being assessed at that moment is not the error but your professional response to it. The sequence that works:
- Acknowledge it plainly. "You are right - that value is wrong." Do not argue, and do not go silent.
- Explain the cause if you can see it: a transcription slip, a sign error in the traverse adjustment, an unapplied correction.
- Quantify the effect. Does it move a beacon by 3 mm or by 3 m? Does it change the area? Does it push the traverse outside the 1:3,000 standard of regulation 3?
- State the corrective action. What you would recompute, what you would re-observe, and what you would report to the Surveyor-General if it affects an existing mark.
That last step matters. Regulation 28 requires that where a surveyor discovers a disagreement in data, or damage to, loss of or displacement of Government beacons, he shall make careful search and inquiry and forward a full report to the Surveyor-General, with a record of the accurate positions determined, explanatory diagrams, descriptions of the beacons, and particulars of development in the neighbourhood. A candidate who reaches that answer unprompted has demonstrated exactly the reflex the Council is looking for.
4. The standard scenarios
| Scenario | The reasoning the panel wants |
|---|---|
| You discover during survey that the client's fence encroaches on the adjoining parcel. | Survey and show the true position on the plan. Regulation 23 permits you to decline to demarcate the disputed portion where the adjoining owner objects, and expressly provides that the survey and demarcation are not thereby incomplete so far as the surveyor is concerned. |
| On resurvey the ground beacons disagree with the original plan data. | Regulation 27: unless the original beacons have obviously been disturbed, the beacons on the ground indicate the true boundary, even though the resurvey data disagrees with the plan. Then report under regulation 28. |
| The client asks you to move a beacon by 'just a metre' to clear a structure. | Refuse. Regulation 29 permits amendment of a Government survey and removal or re-siting of Government beacons only on the Surveyor-General's instructions, and the surveyor must report in writing when carried out. Beyond that, falsifying a boundary is infamous conduct in a professional respect under s.17(1)(a) of the SURCON Act. |
| You are asked to sign a plan prepared by someone else. | The signature is a personal warranty. Practising or holding out to practise while unregistered is an offence under s.18(1); a registered surveyor who lends a signature to such work exposes himself to a direction of the Disciplinary Committee under s.17. |
| Another surveyor previously acted for this client. | Deal with it in writing and confirm the prior engagement is at an end. Section 20 of the Act bars a person who is not fully registered from recovering fees by process of law - a reminder that professional entitlement and professional courtesy both turn on status. |
| A beacon has been destroyed by road works. | Report under regulation 26 - removal, obliteration or defacement of any survey mark coming to a surveyor's notice shall be reported in writing to the Surveyor-General. Note that the State Survey Law also makes it an offence, and imposes a duty on owners, occupiers, chiefs and local governments to preserve marks and report damage. |
5. Presenting yourself
- Bring the working papers. If the panel asks for a computation you did not bind into the Folio, being able to produce it is worth more than any rehearsed answer.
- Answer the question asked. Long pre-prepared speeches invite the panel to interrupt and probe elsewhere.
- Say when you do not know. "I have not encountered that; my understanding would be X, and I would check the Regulation before acting" is a professional answer. Guessing confidently is not.
- Do not disparage your supervisor, the client, or the previous surveyor. The panel is assessing your professional conduct in the room as well as in the field.
- Carry the position you took in Paper VII. If you argued for a geocentric datum in the essay, be ready to say what it costs a small practice to adopt one.
During a resurvey, the coordinates you obtain for existing boundary beacons disagree with the data on the original plan, and there is no sign that the beacons have been disturbed. What does regulation 27 of the Survey Regulations require?
An adjoining owner objects to the position of a boundary as pointed out by your client. Under regulation 23, what is the correct course?
A client asks you to shift an established beacon by one metre so that it clears a new structure. Which authority most directly governs your refusal?
An examiner finds a genuine arithmetical error in your Folio computation during the oral defence. What sequence of responses best demonstrates professional judgement?
