Decommissioning
Approaching asset closure with confidence
Ageing infrastructure is characterised by corrosion, deterioration and contamination. Original documentation may not be available to guide the planning required for decommissioning and the presence, location, and volume of hazardous materials may not be known. Without taking the necessary time, effort, and resources to understand the decommissioning risks and feasible project methodologies, a project can easily unravel.
Specialising in the decommissioning of industrial, energy, mining, and manufacturing facilities, DEMEX is among Australia’s leading decommissioning and demolition contractors. We provide commercial and industrial decommissioning of complete and partial structures (internal and external), bridges, structures at height, multi-level structures, detailed and intricate demolition, and high risk demolition requiring specialised machinery and project management. Working Australia-wide in urban, regional, and remote sites such as mines and power stations, we are licensed to provide unrestricted demolition services for the mining, resources, and government sectors. Our capacity for innovation and unwavering commitment to safety means we’re never daunted by a project’s complexity, location, size or duration.

Safe and effective decommissioning project completion
Â
Decommissioning and demolition is high risk work, and it is with this understanding that we apply a ‘safety first’ approach to every project. Our safety systems are independently certified and we deliver our clients’ projects in full compliance with all health, safety, and environmental standards, including:
- Model Code of Practice: Demolition work
- ISO 9001:2015 - Quality Management SystemsÂ
- ISO 14001:2015Â - Environmental Management SystemsÂ
- ISO 45001:2008 - Quality Health and Safety Management Systems
- FSC Accreditation.
Consistent with these independent standards, our business is underpinned by strong systems, commercial robustness, and insurances that provide confidence to our clients. Full details of our approach to demolition and decommissioning projects can be found here.
Â
Â
Meeting social and environmental obligations
Â
Decommissioning of major facilities, such as mines, power stations, and manufacturing plants invariably draw scrutiny from external stakeholders who want to know that the project is being conducted in a way that meets all the asset owner’s obligations. When performed well, decommissioning projects can achieve recycling rates in excess of 90 percent, limiting the volume of waste to landfill, and maximising the volume of resources to be salvaged. By working with an experienced decommissioning contractor, project owners can be confident they are meeting or exceeding stakeholder expectations and regulatory requirements for closure.
Â
Â
Effective use of resources
Â
A reliable well-maintained fleet is pivotal to successful delivery of every project and specialist high reach excavators are ideal for industrial projects. Its many benefits include:
- Making complex work at heights more manageable, as safety and environmental risks can be minimised.
- It significantly reduces the time required for demolition, allowing project delivery to be more efficient and project schedules to be accelerated.
- Precision in delivery; a benefit evident particularly in dismantling of buildings positioned in awkward and difficult to reach spaces, such as in heavily built up urban zones.
Effective in action, high reach demolition excavators are a valuable addition to projects requiring extra reach, delivered safely.
