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.
iEnvi completed a Delineation Investigation (DI) at an aerosol and paint manufacturing site in northwest Sydney. The DI installed three groundwater monitoring wells, 13 soil bores and two stormwater points, collecting 8 groundwater, 39 soil and 2 stormwater samples. Findings showed minor soil hydrocarbons (one local exceedance), groundwater elevated dissolved metals likely related to background geochemistry, and isolated vapour-intrusion exceedances — prompting targeted sub‑slab vapour testing and further risk-management recommendations to meet NSW EPA expectations.
What is Site Investigation? Site investigation is the process of gathering information about the physical characteristics of a construction site to ensure its suitability for a…
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.
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.
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 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.
iEnvi expanded its network of independent contaminated‑land sub‑consultants in 2022 to improve local availability, technical depth and delivery flexibility for clients across Australia.
