Reducing Site Visits: A New Way of Thinking About Vegetation Management

When people think about utility infrastructure, they typically focus on the assets themselves: substations, transmission lines, transformers, pipelines and transport corridors. Yet keeping these assets safe, compliant and operational requires a significant amount of supporting maintenance activity. One of the most important, and often least visible, is vegetation management.

Across Australia, utility owners and contractors invest millions of dollars each year managing vegetation around critical infrastructure. Whether maintaining bare ground within substations, controlling weeds along access tracks, managing fence lines or reducing fire risk around assets, vegetation management plays a critical role in protecting both infrastructure and the communities it serves.

Traditionally, discussions around vegetation management have centred on operational metrics such as cost per hectare, contractor rates or treatment costs. While these measures remain important, they overlook a broader consideration that is becoming increasingly relevant across the utility sector:
how many times are we exposing people to risk in order to achieve the desired outcome?

As organisations continue to strengthen their safety culture, manage workforce shortages and seek greater operational efficiency, there is growing recognition that vegetation management should be viewed through a wider lens than simply weed control.

Every Site Visit Creates Exposure
Every maintenance visit carries an inherent level of risk. Before any work begins, personnel must travel to site, often over long distances and in varying conditions. Vehicles must be operated on public roads and access tracks. Equipment must be transported, unloaded and used safely. Workers may be operating in remote environments, extreme weather conditions or around critical infrastructure. While these activities are routine, they all contribute to the overall exposure profile of a maintenance program. According to Safe Work Australia, vehicle incidents remain one of the leading causes of workplace fatalities, highlighting that risk often exists long before work commences on site. For utilities managing large networks of geographically dispersed assets, the cumulative exposure associated with routine maintenance can be substantial. This raises an important question: should vegetation management programs be assessed solely on the cost of each intervention, or should they also consider the risks associated with delivering those interventions?

The KPI Few Organisations Measure
Most maintenance programs are designed around achieving an operational outcome. Vegetation is controlled, assets remain accessible and compliance requirements are met. However, the metrics used to evaluate success often focus on inputs rather than exposure.

Questions commonly asked include:
• What did the treatment cost?
• How many hectares were treated?
• How many contractor hours were required?

Less commonly discussed are metrics such as:
• Number of site visits per year
• Vehicle movements
• Kilometres travelled
• Hours spent working around live assets
• Contractor mobilisation events
• Permit and access requirements

Two maintenance programs may achieve the same outcome yet require vastly different levels of exposure to deliver. In an industry where safety performance is a core priority, this represents an opportunity to think differently about how vegetation management success is measured.

Learning from Modern Asset Management
Utilities have become increasingly sophisticated in the way they manage physical assets.
Maintenance strategies are now commonly based on risk, reliability and whole-of-life cost rather than simply addressing problems as they arise. Organisations routinely invest in solutions that reduce maintenance frequency, improve predictability and minimise operational disruption. Vegetation management is well positioned to follow the same path. Rather than viewing vegetation as a recurring maintenance task, there is an opportunity to consider it as part of a broader asset protection and risk management strategy.

Effective vegetation programs can contribute to:
• Improved asset accessibility
• Reduced fire risk
• Enhanced site safety
• Greater maintenance predictability
• Reduced contractor exposure
• Lower whole-of-life maintenance costs

Importantly, these benefits extend beyond vegetation itself and contribute to broader organisational objectives.

A Shift Towards Smarter Maintenance
Across the infrastructure sector, there is growing emphasis on reducing unnecessary interventions wherever possible. Advances in technology, planning and maintenance strategies are enabling organisations to achieve operational outcomes with fewer site visits, fewer disruptions and lower exposure to risk. Vegetation management should be part of this conversation. By focusing on long-term outcomes rather than individual interventions, organisations can begin to evaluate maintenance programs based not only on what they cost, but on how efficiently and safely they achieve their objectives. This approach aligns with many of the broader challenges facing the utility sector today, including workforce availability, contractor capacity, safety performance and operational resilience.

Looking Ahead
As Australia’s infrastructure networks continue to grow and community expectations increase, utilities will be challenged to find new ways to improve safety and efficiency simultaneously.
Vegetation management may not always receive the same attention as major assets or capital projects, but it remains an essential component of network performance. The next evolution in vegetation management may not be defined by hectares treated or contractor hours delivered.
Instead, success may increasingly be measured by a simpler question: how many times did we need to send people to site in the first place?

As vegetation management continues to evolve from a routine maintenance activity into a broader asset protection and risk management discipline, collaboration between asset owners, contractors and technical specialists will become increasingly important.

At Envu, we work alongside utilities, transport operators, contractors and infrastructure owners across Australia to help develop vegetation management programs that improve safety, operational efficiency and long-term asset performance. Our team brings expertise across vegetation management technologies, herbicide solutions and integrated vegetation management strategies, supporting organisations as they navigate increasingly complex operational and regulatory environments.

Whether you’re reviewing existing vegetation management practices, exploring ways to reduce maintenance frequency, or looking to better understand the whole-of-life costs associated with vegetation control, we welcome the opportunity to share experiences and learn from others across the industry.
