Key takeaways
- A layout change needs an authorised decision and a traceable revision, rather than an informal agreement between whoever happens to be nearby.
- A message saying move the cones does not identify an approved arrangement. A photograph of the finished layout does not explain who approved it.
- The revised arrangement has been authorised through the project's change process, communicated and checked on site.
A layout change needs an authorised decision and a traceable revision, rather than an informal agreement between whoever happens to be nearby. This changing tgs on site field guide gives the office and site supervisor a practical preparation checklist, a worked scenario and a clear completion test. Use it to organise the conversation and evidence; the project's current authorised documents remain the basis for technical and statutory decisions.
The decision to make before starting
A layout change needs an authorised decision and a traceable revision, rather than an informal agreement between whoever happens to be nearby. Write the decision in terms that someone outside the immediate conversation can understand. Identify the job or asset, the proposed activity and the person responsible for the next step. An unresolved decision should remain visible instead of becoming an assumption carried into dispatch.
Do not confuse a request with approval. Where the work depends on an authority, designer, employer or contract decision, ask that responsible party for the applicable requirement. Confirm which version and date apply to this job; a previous project's answer may be useful background but is not automatically the current instruction.
A worked planning scenario
The excavation moves towards a driveway that the approved drawing shows as open. The crew should identify the discrepancy before relocating the work zone. This is an illustrative planning situation, not a reported incident or a claim about a particular customer. The useful question is what information the next person needs before acting.
In this situation, separate facts already confirmed from details still being checked. Assign the missing check to a named person and tell the affected team when to expect an answer. If the answer changes the planned work, update the source record and brief the people who relied on the earlier version. Keeping the old version available helps explain the change later.
Practical checklist
| Step | Check or action | Evidence of follow-through |
|---|---|---|
| 1 | Compare the actual work boundary with the drawing | Name an owner and record the result |
| 2 | Identify affected approaches and driveways | Name an owner and record the result |
| 3 | Contact the nominated supervisor or designer | Name an owner and record the result |
| 4 | Record the revised reference | Name an owner and record the result |
| 5 | Brief everyone affected before restarting | Name an owner and record the result |
Run through the checklist with the people who will actually deliver or review the work. Write not applicable only with a reason; leave unanswered items as open actions. The purpose is to expose gaps early, rather than produce a page of ticks after the event. Include the relevant reference beside the result so another reviewer can find the supporting material.
Mistakes to catch during review
A message saying move the cones does not identify an approved arrangement. A photograph of the finished layout does not explain who approved it. Ask the reviewer to explain the difference between what was requested, what was authorised and what actually happened. If those differ, record the reason and decide whether a further approval or corrective action is needed.
Check timestamps and record identity as well as the apparent outcome. A photograph, message, invoice or status badge can support a decision, but each has limits. Do not infer a person's competence, a technical approval or a legal entitlement from a field that was designed to show something narrower. Resolve conflicting information with the responsible person rather than quietly replacing inconvenient evidence.
What the job record should contain
Original drawing reference, reason for change, approving person, decision time, revised drawing and crew briefing acknowledgement. Keep related material together under a stable job, person or asset reference. Use clear file names and preserve the original record when an adjustment is made. Restrict access to people who need the information for the task, especially where employee details, signatures or location observations are involved.
Record the owner, due time and next review trigger for anything outstanding. A good record lets the incoming shift or office reviewer answer three questions: what has been confirmed, what still needs a decision, and who is responsible for it? Avoid personal speculation; factual descriptions are more useful when someone checks the record weeks later.
Completion and handover test
The revised arrangement has been authorised through the project's change process, communicated and checked on site. If that statement cannot yet be supported, identify the open item and communicate its effect on the planned work. Do not label the matter complete merely because a form was saved or an email was sent.
Before handing over, ask the receiving person to locate the current instructions and explain the outstanding actions. Reopen review when the work scope, conditions, responsible contact or supporting evidence changes materially. That makes the checklist an operational control rather than an archive of a decision that is no longer applicable.
Further reading and next steps
For the wider booking process, read what to confirm in a traffic control quote and how shift dockets support office review. For work-zone planning context, see the difference between a TMP and TGS.
Check the responsible authority's current requirements through Transport for NSW or Queensland Transport and Main Roads, as applicable. Safe Work Australia provides workplace traffic management guidance; use the relevant local regulator for jurisdiction-specific obligations. These references provide context, not approval of a particular site arrangement.
Use your company's existing job and document records to track the checklist. TrafWise can help keep operational records together; confirm which workflow and configuration your company has enabled before relying on an automated status or reminder.
Frequently asked questions
What should we decide first?
A layout change needs an authorised decision and a traceable revision, rather than an informal agreement between whoever happens to be nearby.
What is a common mistake to avoid?
A message saying move the cones does not identify an approved arrangement. A photograph of the finished layout does not explain who approved it.
Which evidence should we retain?
Original drawing reference, reason for change, approving person, decision time, revised drawing and crew briefing acknowledgement. Link it to the relevant job, person or asset and preserve the history of any correction.
When can we mark the action complete?
The revised arrangement has been authorised through the project's change process, communicated and checked on site. If evidence is missing, keep the action open with a named owner and next review time.
