Traffic control under Part 18: the plan, who may direct traffic and the manual
A concrete pump is booked beside a mixed-use building. The lane-closure permit has arrived, and the delivery coordinator assumes that cones and two available labourers will cover traffic. The traffic contractor asks for the actual work-zone arrangement.
Part18 requires effective traffic control when traffic could endanger workers. It calls for a qualified risk assessment; short- and long-duration work require a written assessment and traffic-control plan. The provincial Traffic Management Manual applies to work zones. Control measures follow an order that considers isolation and other controls before traffic-control persons. Required TCP training, supervision, work-zone orientation and equipment are separate checks. A municipal permit does not supply all of those decisions.
Check the requirement against the actual work
- Describe the work zone before selecting a diagram. Provide the traffic specialist with the proposed pump position, vehicle movements, work duration and affected approaches. Identify adjacent access and what changes during setup, concrete delivery and removal. Let the qualified assessment determine the needed arrangements. Do not convert a similar-looking diagram from another project into a site-specific answer by changing its title.
- Locate the assessment and current plan. Confirm that the documents describe the scheduled work and that the responsible person has resolved missing information. Find the plan’s implementation roles, review arrangements and instructions. Keep the accepted version accessible to the work zone. Separate any road-authority conditions from the employer’s safety requirements so a missing permit attachment does not disappear inside a general safety binder.
- Verify the assigned people and equipment. Check the evidence for the personnel actually booked, including the applicable TCP training. Ask who supervises the arrangement and delivers the work-zone orientation. Compare the specified devices and apparel with what will arrive. This lesson does not teach hand signals, sign spacing or deployment methods; obtain those instructions through the applicable plan and competent personnel.
- Review installation and changing access. Ask the traffic supervisor how the arrangement covers the periods when devices are installed, changed and removed. Include deliveries that were added after the first plan was prepared. Establish how a blocked route, new access request or changed work time reaches the responsible reviewer. A pump relocation can change the question even if the original lane permit remains valid.
- Record readiness before dispatching the pour. Use distinct entries for the plan, personnel, equipment and unresolved authority conditions. Name the owner and required evidence for each pending entry. Tell the concrete coordinator the actual status rather than marking the entire package “approved.” Recheck relevant changes with the traffic supervisor and communicate the resulting instructions to the affected work.
Common mistakes
- Treating the road permit as the traffic-control plan.
- Using personnel availability as proof of TCP training.
- Changing a pump position without reviewing the work zone.

Check your understanding
The permit was issued yesterday. Can the delivery coordinator close the traffic item?
