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.
Targeted landfill gas and groundwater assessment at an operating bus depot adjacent to two closed municipal landfills in Melbourne’s western suburbs. No methane detected and EPA Victoria action levels not exceeded. Planning condition satisfied with no further LFG controls recommended.
iEnvi conducted a Preliminary Site Investigation and soil testing across a large greenfield parcel in Melbourne’s northern growth corridor. Surface sampling and stockpile checks found no asbestos or contaminant levels above NEPM Tier 1 screening criteria for sensitive land uses, supporting school development approval with practical construction-phase recommendations.
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.
How a lean, risk‑focused contaminated‑land approach gave a community sports club a construction‑ready landfill gas assessment and a practical Construction Environmental Management Plan (CEMP) so the clubhouse could be built safely, on time and on budget.
iEnvi completed a desk-based Preliminary Site Investigation (PSI) for a proposed residential development in inner Melbourne, Victoria. The PSI found a low risk of contamination, confirmed intrusive soil testing was not required, and enabled the planning application to proceed without an environmental audit.
Targeted soil assessment of a former oyster farm footprint identified low-risk PAH sources (asphalt fragments) rather than residual coal tar, resolving a data gap and enabling council approval for low-density residential development.
iEnvi managed in‑situ abandonment of three underground storage tanks at a commercial property in the Wide Bay region, QLD, using foam filling to avoid structural impacts. Work complied with AS4976‑2008 and included guidance on validation groundwater monitoring and UPSS completion to progress removal from the QLD Environmental Management Register.
Case study: CEMP, ESCP and VMP prepared by iEnvi for a regional council to manage vegetation clearing, earthworks, acid sulfate soils, fauna risk and sediment during construction of a sports complex in South East Queensland.
