Key takeaways
- Roadworks at a signalised intersection should be coordinated with the responsible road and signal-operation parties as required by the project. Describe the actual stage, affected movements and plant access to competent reviewers. A temporary roadwork arrangement should not be treated as permission for a crew to modify signal operation or associated infrastructure.
- Identify road and signal-operation contacts.
- Readiness means the relevant competent parties have coordinated the actual stage and the field team has clear instructions within its authorised role.
Roadworks at a signalised intersection should be coordinated with the responsible road and signal-operation parties as required by the project. Describe the actual stage, affected movements and plant access to competent reviewers. A temporary roadwork arrangement should not be treated as permission for a crew to modify signal operation or associated infrastructure.
This guide is for contractors, allocators and site supervisors preparing the decision described above. The examples are hypothetical planning situations, not reports of incidents or customer results. Use the current approved project documents and responsible authority's requirements for technical decisions. National guidance, local adoption and a particular permit condition are different references; confirm which applies to your work rather than assuming a rule from another project transfers unchanged.
Identify operational and infrastructure responsibilities
Establish who manages the road, signals and relevant project approvals. Provide consistent location and scope information to each party. Ask what involvement or authorisation is required for the proposed work. Do not assume that a general road occupation permission covers every signal-related interface, and do not assign technical operation changes to someone whose role does not authorise them.
Describe all affected movements
Map the work footprint against vehicle, walking and cycling movements and associated access. Give the designer the expected delivery and plant pattern. The visible vehicle lane is only part of the context. A stage may change how people approach a crossing or access a nearby property even when the contractor expects traffic to keep moving.
Reconcile stages and specialist attendance
If the project needs specialist involvement, identify the timing and decision dependencies before booking implementation. Confirm who says the prerequisites are satisfied and who communicates delay. A provisional attendance window is not proof that a stage can start. Keep the relevant contacts and current instructions in the work pack so the field team does not have to reconstruct the coordination history.
Record authorised changes and handback
Where the stage or responsible operator’s instructions change, retain the decision and briefing record. Confirm the applicable handback or reinstatement process with the competent parties. Do not infer completion from the departure of the construction crew alone. Any continuing arrangement should have an identified owner and a usable escalation route for the next shift or operator.
Practical preparation checklist
| Check | What to capture in the job record |
|---|---|
| Identify road and signal-operation contacts | Relevant location, stage and source reference |
| Describe all affected public movements | Responsible person and confirmed decision |
| Confirm specialist prerequisites | Supporting document revision and status |
| Keep current authorised instructions | Open question, action owner and review point |
| Record stage handback responsibilities | Instruction issued and handover acknowledgement |
Use this as a preparation aid, not a declaration that a site complies with every requirement. Mark an item unresolved if the supporting information is missing. Ask the person responsible for the decision to confirm the outcome; a completed form should show what has been checked and what still needs attention. Keep the original record when an instruction changes so the next reviewer can understand the sequence.
Worked example: where the decision can go wrong
A hypothetical contractor moves a delivery across an intersection after the initial stage review. The responsible team should assess the new movement and any operator involvement before it is implemented. An informal agreement to stop a movement temporarily would not establish that all affected interfaces and permissions had been resolved.
Completion test and handover
Readiness means the relevant competent parties have coordinated the actual stage and the field team has clear instructions within its authorised role.
Before handing over, identify the current instructions, supporting evidence and any action still open. The receiving person should be able to locate those records without reconstructing a private conversation. If the work method, location, responsible person or conditions change materially, refer the affected decision for review through the project process. Recording a task as complete should not conceal a separate approval or technical acceptance that remains outstanding.

Frequently asked questions
What should we check first for signalised intersection roadworks?
Establish who manages the road, signals and relevant project approvals. Provide consistent location and scope information to each party. Ask what involvement or authorisation is required for the proposed work. Do not assume that a general road occupation permission covers every signal-related interface, and do not assign technical operation changes to someone whose role does not authorise them.
What information needs to be confirmed?
Map the work footprint against vehicle, walking and cycling movements and associated access. Give the designer the expected delivery and plant pattern. The visible vehicle lane is only part of the context. A stage may change how people approach a crossing or access a nearby property even when the contractor expects traffic to keep moving.
Which responsibilities should be agreed?
If the project needs specialist involvement, identify the timing and decision dependencies before booking implementation. Confirm who says the prerequisites are satisfied and who communicates delay. A provisional attendance window is not proof that a stage can start. Keep the outcome documented.
When should the proposed approach be reviewed?
Where the stage or responsible operator’s instructions change, retain the decision and briefing record. Confirm the applicable handback or reinstatement process with the competent parties. Do not infer completion from the departure of the construction crew alone. Any continuing arrangement should have an identified owner and a usable escalation route for the next shift or operator.
