iEnvi supported a Tier 1 contractor delivering NBN trenching and pit works across a major Brisbane infrastructure precinct, managing PFAS and asbestos risk with in‑situ waste classification and immediate backfill to meet Commonwealth safety requirements and avoid costly hazardous disposals.

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.

Ensuring Safe School Development: Soil and Asbestos Investigations in Melbourne’s Northern Growth Corridor

Proposed school site with stockpiles in distance

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.

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.

Preliminary Site Investigation, Inner Melbourne Residential Development

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.

Soil Investigation Clears Path for Safe Construction at Chemical Site, Victoria

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.

Preliminary Site Investigations for Potential Acquisition, VIC and WA

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.

iEnvi completed an Underground Petroleum Storage System (UPSS) integrity check and Detailed Site Investigation (DSI) at a service station with an attached dwelling in Far North Queensland. Soil sampling adjacent to former tanks, fuel lines and bowsers found evidence consistent with a fuel-line leak; iEnvi provided a staged investigation and cost estimate to support purchase negotiations and subsequent remediation works.
