iEnvi supported a Tier 1 contractor to deliver NBN trenching and pit works across Brisbane Airport precincts, managing PFAS and asbestos risk, enabling in‑situ waste classification and immediate backfill to meet Commonwealth safety requirements and avoid costly hazardous disposals.
A concise, defensible Preliminary Site Investigation (PSI) and targeted soil screening at a former regional Queensland sawmill clarified contamination risk (timber-treatment residues, unknown fill, petroleum), updated the conceptual site model and set clear triggers for any further DSI or groundwater work — supporting sale, planning and due diligence.
iEnvi completed a targeted, construction‑friendly Baseline Contamination Investigation at a large southern Brisbane warehouse and logistics facility to provide a defensible contamination snapshot for lease handover. The program combined desktop records review, GPR service clearing, targeted drilling (8 locations to ~8 m), 16 primary soil samples plus QA/QC for TRH, BTEXN, PAHs, metals and asbestos, and a Baseline Contamination Report signed by a CEnvP Site Contamination specialist.
iEnvi conducted a Preliminary Site Investigation and soil testing across two lots (≈9.9 ha) in Wollert, Victoria. Eleven surface samples and stockpile checks found no asbestos or contaminant levels above NEPM Tier 1 screening criteria for sensitive land uses, supporting school development approval with a small set of practical recommendations for construction-phase controls.
Targeted, NEPM‑aligned due diligence (PSI + simple tenant lines of enquiry) to give fast, proportionate assurance for acquisition and staged redevelopment of an industrial site in South Australia — reserving intrusive investigation for clearly observed triggers.
iEnvi completed a desk-based Preliminary Site Investigation (PSI) for a proposed residential development in Abbotsford, VIC. The PSI found a low risk of contamination, advised that intrusive soil testing was not required, and enabled the planning application to proceed without an environmental audit.
iEnvi completed an asbestos- and contaminant-focused soil classification at an industrial chemical site in Melbourne, providing a compliant, cost-effective pathway for excavation and construction of a flammable goods storage area.
iEnvi completed urgent preliminary site investigations at three metal fabrication sites (QLD, NSW, SA) for M&A due diligence, delivering PSI reports within one week and recommending targeted soil testing where moderate–high risks were identified.
Two coatings manufacturing sites in Victoria and Western Australia were assessed by iEnvi through preliminary site investigations (PSI) to identify contamination risks, regulatory implications and recommended next steps for acquisition decisions.
