5General maintenance requirements#

5.1Maintenance programs#

Ownership of the ITS installation is to be confirmed before maintenance is undertaken. The programming of maintenance activities for ITS equipment is the responsibility of the Regions/Districts and is generally carried out under the Road Maintenance Performance Contract (RMPC). Refer to Element Management Plan No. 34.

5.2Applicable standards#

Work is to be carried out in accordance with Transport and Main Roads specifications, AS/NZS 3019 Electrical Installations – Periodic Verification and the Electrical Safety Act 2002, Regulations and Codes of Practice (The Act). All works, processes and procedures used in maintenance activities associated with the electrical works described herein is be in accordance with The Act. Electrical maintenance is not to be carried out live except as permitted under The Act.

The following are the key regulations and technical standards applicable to the departments ITS

5.3Installation drawings#

Installation drawings are required for the safe maintenance of electrical installations. Regions/Districts are to work with the maintenance provider to ensure that electrical installation drawings are current and reflect the actual state of the installation. Where drawings are incorrect and/or non-existent, Regions/Districts are to arrange for accurate drawings to be produced. Drawings are to conform to the requirements of the Transport and Main Roads Drafting and Design Presentation Standards manual. Where modifications or alterations are made to the installation as-constructed drawings and records of tests are to be provided.

5.4Maintenance personnel#

Personnel undertaking ITS maintenance activities (including the Superintendent's Representative) are to have the appropriate qualifications, training and experience necessary to undertake their designated activities in a safe and considered manner. These are to include working in a high speed road environment, knowledge of MUTCD Part 3 and relevant MRTS.

The possession of a valid Occupational Health and Safety Construction Induction card (also known as a ‘White Card’ or the previous ‘Blue Card’) and a current adult First Aid Certificate are also prerequisites for all persons working on ITS installations.

If the maintenance involved electrical equipment, they must be approved by the Electrical Safety Office (ESO) to work under the Department of Transport and Main Roads Electrical Contractors License (possession of a ‘Green Card’).

Appropriate training of personnel is the responsibility of the organisation providing the maintenance service. Regions/Districts are responsible for collecting this information from the service provider and are to undertake random audits to ensure compliance.

5.5Maintenance plant and equipment#

When maintaining ITS supporting structures such as mast arm installations, elevated work platform (EWP) vehicles are to be used. Every operator is to possess a valid EWP operator ticket, relevant driver’s licence and is to have an appropriate level of experience in EWP operation. Operators are to have training in safe work procedures and evidence of such training.

Vehicles are to have safety checks and have valid current certification in accordance with the relevant parts of:

• AS 1418.10 Cranes, hoists and winches – Part 10 Elevated working platforms
• AS 2550.10 Cranes, hoists and winches safe use – Part 10 Mobile elevated working platforms
• AS 4748 Acoustic emission testing of fibreglass insulated booms on elevated work platforms

Equipment used for maintenance is to comply with relevant safety legislation and standards and be appropriate for the application. Testing equipment calibration is to be current with calibration evidence included in the maintenance report. Regions/Districts are to undertake random audits to ensure compliance.

5.6Maintenance waste disposal#

The current rating and characteristics of electrical circuit protection devices are to be no greater than those specified on the Standard Drawings or manufacturer's documentation. Installations that do not comply with the requirements of The Act are to be rectified.

The photometrics, electrical and ingress protection characteristics of replacement aspects are to be such that the lighting and electrical integrity of the installation are not compromised.

5.8Traffic management#

Safety and traffic control plans where required are to be approved by the Region/District before maintenance work is conducted.

All signage used during maintenance is to be in accordance with Part 3 of the Manual of Uniform Traffic Control Devices (MUTCD).

Minimum details required to be logged and reported include:

• site number
• name of road and/or road number
• region/district number
• date installation commissioned or date manufactured
• type of maintenance service – damage/fault, replacement of parts, routine spot, etc.
• item maintained – pit, post, lens, camera, switchboard, lamps, etc.
• part(s) replacement date
• verification process carried out
• name of maintenance service provider (Contractor company name and maintenance personnel)
• date maintained.

Where applicable, the ITS and Electrical “Road Operations Asset Maintenance System” (ROAMS) is to be used.
