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 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.
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 investigated asbestos‑impacted soil and groundwater at an industrial site in Coolaroo (VIC). Bonded asbestos in stockpiled soil was removed by hand‑picking (emu‑picking) and the remaining material verified for reuse as clean fill, avoiding costly landfill disposal while meeting EPA Victoria obligations under the General Environmental Duty.
iEnvi completed a rapid preliminary site investigation (PSI), soil sampling (60 samples) and geotechnical site classification for a 75‑lot low‑density residential proposal on former citrus orchard land in Griffith LGA. Soils met NSW Excavated Natural Material criteria and the site was classified as moderately reactive (20–40 mm movement potential).
iEnvi completed two fast-turnaround Preliminary Site Investigations (PSI) near Adelaide, SA. One site showed significant risk from past loam mining and fill and requires a larger investigation, remediation and auditor sign-off; the second was suitable for a 50‑lot subdivision after limited sampling.
Desktop (Phase 1) preliminary site investigation for a proposed child care centre in Sydney’s Northern Beaches. The desktop study identified low contamination potential from on‑site history but recommended targeted soil sampling and an asbestos hazardous‑materials inspection before council proceeds with a development application.
Case study: PSI, combined geotechnical and environmental drilling, 30 soil bores to 5 m, 15 primary soil samples. Delivered reporting for planning permit in ~2 weeks; cost reported just over $10,000. Practical takeaways for developers on compliance, demolition hazards and cost efficiencies.
iEnvi completed a rapid Preliminary Site Investigation (PSI) to support a developer converting a post‑war residence to a childcare facility in Western Sydney. The PSI followed NEPM guidance and NSW child‑care planning requirements, found low contamination risk, and recommended asbestos inspection prior to renovation.
