iEnvi’s soil investigation and risk assessment at a former timber yard in the Wide Bay region of Queensland confirmed suitability for commercial use, with no remediation required for the current land use.
iEnvi completed a landfill gas preliminary site investigation and risk assessment in south-west Brisbane to support a warehouse development application next to a closed landfill. No detectable methane was recorded, supporting an indicative CS1 classification under the NSW EPA 2020 ground-gas framework.
iEnvi provided an independent asbestos source assessment and post-removal clearance at a greenfield development in south-west Sydney. 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.
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.
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 investigated asbestos‑impacted soil and groundwater at an industrial site in northern Melbourne (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.
Remediation program for Cr6+ impacted soils and fractured-basalt groundwater at a long‑running steel processing facility. Summary of contamination, in‑situ treatment techniques trialled, pilot results and commercial considerations for redevelopment and liability management.
