Demolishing old buildings or infrastructure is rarely straightforward – but when contamination is present, these works only get more complex.
In Western Australia, brownfield sites and other areas impacted by historical land use often require something more than standard demolition practices. Often, you will need to secure environmental remediation services that ensure effective management of contaminated materials, adherence to regulations and proper planning. Engaging experienced consultants is the surest way to protect both people and the environment.
In this article, we outline the factors you should consider before and during demolition and how West Soil and Water (WSW) can assist.
The first step in any demolition project is to determine what contaminants may be present. Common contaminants on Western Australian sites include:
Asbestos containing materials (ACMs) in roofing, insulation or cladding.
Lead based paints and coatings, which are still common in older structures.
Hydrocarbon residues from underground tanks or industrial equipment.
Heavy metals in soils beneath concrete pads or drainage lines.
Completing a Preliminary Site Investigation (PSI) will establish the likelihood of contamination. Should contamination be present, a Detailed Site Investigation (DSI) will, through sampling and laboratory analysis, confirm levels and risks. If you are demolishing a structure on your site, it is best to take these measures early to prevent delays later in the timeline.
Demolition on contaminated land must follow strict regulatory frameworks. In WA, the Contaminated Sites Act 2003 mandates accurate reporting and responsible management of identified contamination.
WorkSafe WA and the Department of Water and Environmental Regulation (DWER) also have guidelines covering asbestos removal, waste classification and safe disposal practices.
Non-compliance can result in fines, liability for clean-up costs and reputational harm. WSW’s consultants are experience in proving environmental compliance for contaminated sites. We can assist you in meeting your obligations whilst avoiding any unnecessary red tape.
Demolishing a contaminated structure can pose direct risks to staff and surrounding communities. Airborne dust, asbestos fibres and soil disturbance are some of the most common hazards.
Best-practice measures include:
Establishing dust suppression systems.
Using enclosed removal techniques for asbestos.
Implementing exclusion zones to restrict unauthorised access.
Regular air quality and soil monitoring during works.
At West Soil & Water, our consultants work with external contractors to design monitoring programs that verify the effectiveness of controls and protect public health.
For most projects, demolition and remediation go hand in hand. Rather than treating remediation and demolition as separate tasks, you can integrate the two processes to achieve:
Efficient scheduling that avoids rework or delays.
Cost savings by combining mobilisation of equipment and personnel.
Clearer reporting for regulatory purposes.
Our team specialise in environmental remediation services that can be comfortably aligned with your demolition plans to ensure smooth project progression.
At WSW, we support clients as they navigate the complexities of demolishing structures on contaminated land. Our services invlude
Site investigations to identify contaminants before works begin.
Remediation planning and supervision to ensure contaminants are treated or contained.
Monitoring programs to safeguard workers and surrounding communities.
Guidance on waste classification and disposal pathways in line with WA regulations.
As an experienced soil remediation contractor, we bridge the gap between demolition teams and environmental regulators to ensure your project meets compliance obligations and sticks to budget.
When working on contaminated land, demolishing a structure requires more than just technical demolition expertise. At West Soil & Water, our consultants are trained to identify contaminants, integrate remediation services and manage waste products. With careful planning and compliance management, they ensure site works pose no danger to project viability or the health of wider community.
