Essential maintenance activities

To ensure consistency in our approach on the transport network, we are sharing the advice we’ve given to our contractors regarding activities which can continue during the period of the Level 4 restrictions.

• Response to incidents and emergencies.
• Removal of slips and rockfall where they impact on the carriageway.
• Winter maintenance activities including winter patrols, snow clearance and ice treatment.
• General routine drive over inspections.
• Repair of critical pavement defects such as potholes.
• Removal of detritus where it poses a safety risk.
• Close down of existing work sites where they can be disestablished without compromising safety.
• Sealing or surfacing of section of pavement that are currently unsealed as a result of maintenance activities where sealing of the unsealed patch is considered the safest and most practical option.
• Maintain existing temporary traffic management controls on partially completed works, including site inspections in accordance with CoPTTM requirements.
• Replacement of critical signs such as Stop and Giveway or other signs when the absence of the sign poses a safety risk.
• Repair of damage to barriers, where the damage poses a risk to safety.
• Unblocking of drains where the drain is holding water which becomes a threat to safety, property or the environment.
• Assessing, removing or lopping trees that are damaged and pose a risk to safety or property.
• Bridge maintenance activities where underway and cannot be safely ceased (approval to be given by the System Manager on advice from the Regional Bridge Consultant).
• Street light maintenance, to remove or make safe damage and to restore power when a pedestrian crossing light or belisha beacon not functioning or missing or more than 50% of the lights are not functioning at intersection. Only required where it is considered to be a risk to safety or when advised by a third party.
• ITS system critical maintenance including CCTV Cameras, fixed critical traffic counting sites and Variable Message and other electronic signs.
• Critical maintenance of tunnel mechanical and electrical systems.
• Critical Maintenance of pumps and pumping systems.
• Critical engineering inspections. This would include site visits as a part of the fatal and Serious Crash reporting, inspection and monitoring of active geotechnical issues and urgent structures inspections.
• Establishing and maintaining Traffic Management associated with check points.
