iEnvi provided an independent asbestos source assessment and post‑removal clearance at a greenfield development in Catherine Field. The assessment determined the fragment originated from a historic stockpile, verification testing returned no asbestos detected, and the site was cleared to progress with development.
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.
Practical environmental investigations and compliance audits across four Melbourne bus depots established a defensible baseline, identified localised hydrocarbon impacts near refuelling areas, confirmed no landfill‑gas risk from adjacent closed tips, and delivered reporting and management measures to meet Victorian regulatory expectations.
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.
How a targeted investigation, waste classification testing and a pragmatic remediation strategy closed data gaps for asbestos‑contaminated imported fill in north‑west Sydney — turning a NSW EPA Clean‑Up Notice into a compliant, cost‑efficient remediation pathway.
Practical groundwater monitoring that confirms monitored natural attenuation, meets regulator expectations, and supports a safe transition from quarterly to biannual sampling with clear triggers and contingency planning.
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 Baseline Environmental Condition Investigation (BECI) at an established western Melbourne bus depot to meet Department of Transport & Planning requirements. Targeted soil and groundwater testing (10 soil bores and monitoring wells) found no significant contamination; a Fuel System Operating Plan (FSOP) was recommended and reporting provided regulator‑defensible documentation under Victoria’s Environment Protection Act 2017.
