The site had a history of uncontrolled non-putrescible waste disposal during the 1950s, with presence of asbestos-containing material (ACM), solid inert waste (glass, brick, ceramics), and soil contaminated with heavy metals.
The Environmental Earth Sciences team in Victoria was enlisted as remediation specialists, offering a fixed-cost, fixed-outcome scenario grounded in trusted science, probabilistic cost modelling, collaboration with the consulting branch, and a risk-sharing profile. The project scope encompassed the design and implementation of a soil/waste removal, abatement, and disposal program. This involved the excavation and stockpiling of approximately 13,000m³ of waste material, screening, sorting, and abating asbestos-impacted soil before offsite disposal, categorisation of soils, potential re-use scenarios, and a collaborative backfill program using site-borne natural clay soils. The final validation of excavated surfaces was conducted before audit completion.
The remediation solution delivered a clean site, free from asbestos and other harmful contaminants, providing the client with a valuable asset. Once the excavated pit has been backfilled to surface level, the site will be transformed into a suitable space for low-density residential purposes with no ongoing management requirements. This outcome not only aligns with the client's development goals but also ensures the environmental safety and sustainability of the site for future residential use.
