5.4Roles and responsibilities#
Delete the following RIM responsibility from Table 5.3:
- authorising Design Exceptions (DESs).
5.5Roles and responsibilities for special applications#
5.5.1Road safety barrier systems#
Replace Table 5.14 with the following:
| Task | Description | Competent Person |
|---|---|---|
| Determine the need for a temporary road safety barrier | Works require the use of a temporary road safety barrier system due to worker or road user safety | TMD |
| Selection of temporary road safety barrier system | Compare various temporary road safety barrier systems and select the most suitable for the specific site | TMD who has completed temporary road safety barrier design training and is competent in the design of temporary road safety barrier systems or Specialist temporary road safety barrier designer in consultation with the TMD or Engineer with temporary road safety barrier design expertise |
| Design of temporary road safety barrier in complete accordance with approved guidelines | Complete the design of the barrier system including (but not limited to) the location / length of need / fixing / deflection limits and end treatment requirements | |
| Design of temporary road safety barrier which is outside the scope of the manufacturer's supplied manuals / guidelines | Engineer certification is required for all areas of the design and installation which are outside the scope of (or not included in) the manufacturer's supplied manuals / guidelines | Engineer with temporary road safety barrier design expertise |
| Install a temporary road safety barrier system | Install the temporary road safety barrier as nominated on the TGS, in accordance with the manufacturer’s supplied manuals / guidelines and instructions from the competent person | TMI competent with the installation of the selected temporary road safety barrier or Specialist temporary road safety barrier installer |
| Certification of manufacturer’s supplied manuals / guidelines | Temporary road safety barrier suppliers must ensure all manufacturer’s supplied manuals / guidelines are appropriately certified by an Engineer | Engineer or equivalent with temporary road safety barrier design expertise |
Add the following commentary to Table 5.14:
The Road Safety Barrier Awareness course Transport and Main Roads offers is an awareness course which does not issue attendees with a certificate or competency in road safety barrier design. While the Transport and Main Roads Road Safety Barrier Awareness course will provide some knowledge on temporary road safety barriers, the 'completed temporary road safety barrier design training and is competent in the design of temporary road safety barrier systems' requirement in Table 5.14 would require more than just the completion of the Transport and Main Roads Road Safety Barrier Awareness course.
The following is provided to expand on the requirements in Table 5.14:
- A TMD may determine the need for a temporary road safety barrier.
- A TMD who has completed temporary road safety barrier design training and is competent in the design of temporary road safety barrier systems may, based on site parameters and manufacturer specifications, select or recommend a particular temporary road safety barrier system which will suit the works and the roadworks site.
- A TMD must use the manufacturer’s supplied manuals / guidelines to design the temporary road safety barrier system; however, the TMD would need some expertise in designing temporary road safety barriers and have completed temporary road safety barrier design training and is competent in the design of temporary road safety barriers systems including, at a minimum, training in designing the selected temporary road safety barrier system from the manufacturer’s supplied manuals / guidelines.
- If the temporary road safety barrier design is outside the manufacturer’s supplied manuals / guidelines, then this will require the design to be completed and signed off by an RPEQ with temporary road safety barrier design expertise.
Only road safety barrier systems included on the current list of products in the Transport and Main Roads Accepted Road Safety Barrier Systems and Devices document must be used at roadwork sites in Queensland.
5.5.2Austroads Safety Hardware Training and Accreditation Scheme (ASHTAS)#
In addition to the requirements above, ultimately the Austroads Safety Hardware Training and Accreditation Scheme (ASHTAS) will, over time, offer courses for Safety Barrier Operative (Entry Level), Installers (Permanent and Temporary Safety Barriers), Designers (Permanent and Temporary Safety Barriers), and more.
Austroads has released the Safety Barrier Operative (Entry Level) course and the Installer course for permanent barriers (excluding concrete). Concrete barriers will be included in future updates. Completion of the Safety Barrier Operative (Entry Level) course is a prerequisite for the Installer course. It is expected that Austroads over time will develop Design and Inspection courses.
However, Austroads hasn't established a specific date or timeframe for the Installer - Temporary Barrier course and the Designer - Temporary Barrier course which would be is further away in development.
Once the Installer - Temporary Barrier and Designer - Temporary Barrier courses are available, they will be significantly more effective than the general awareness courses currently available. These ASHTAS courses will have direct input from each product manufacturer and will provide practical training.
Transport and Main Roads requires all individuals involved in the design, installation, and maintenance of temporary roadside safety barriers to obtain an ASHTAS license. The required licence will be based on the training developed and available at that time.

5.6Supervising a Traffic Controller (TC) in training#
When a TC in training is acquiring experience to satisfy the practical assessment component of their training, they must be directly supervised by a TC deemed competent at the relevant TTM Category.
For further information regarding the supervision of a TC in training see QGTTM Part 7 Section 2.2.4.
