Proof in the Soil: PSI and Screening for a Former Sawmill

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.

Fresh Lease, Clean Start: Baseline Check at a Busy Brisbane Logistics Hub

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.

Landfill Gas Assessment — Bus Depot, Albion VIC

Targeted landfill gas and groundwater assessment at an operating bus depot adjacent to two closed municipal landfills. No methane detected; EPA Victoria action levels not exceeded. Planning condition satisfied — no further LFG controls recommended.

Ensuring Safe School Development: Soil and Asbestos Investigations in Wollert

Proposed school site with stockpiles in distance

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.

Confident Acquisition Backed by Targeted Environmental Checks

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.

Building Confidently on a Closed Landfill: Gas Risk Assessment and a practical CEMP

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.

Preliminary Site Investigation – Abbotsford Residential Development

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.

UPSS Abandonment In‑situ via Foam Filling — Hervey Bay, QLD

UPSS abandonment anddecommissioning underground fuel tank QLD

iEnvi managed in‑situ abandonment of three underground storage tanks at a restaurant in Hervey Bay, 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 (EMR).
