iEnvi completed a preliminary site investigation of council-owned former railway parkland in north-east Victoria for a proposed off-leash dog park. Surface soils were below recreational criteria, and a simple construction environmental management plan was recommended.
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.
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.
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 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 completed a rapid preliminary site investigation (PSI), soil sampling (60 samples) and geotechnical site classification for a 75‑lot low‑density residential proposal on former citrus orchard land in the Riverina region of NSW. Soils met NSW Excavated Natural Material criteria and the site was classified as moderately reactive (20–40 mm movement potential).
iEnvi completed two fast-turnaround Preliminary Site Investigations (PSI) near Adelaide, SA. One site showed significant risk from past loam mining and fill and requires a larger investigation, remediation and auditor sign-off; the second was suitable for a 50‑lot subdivision after limited sampling.
iEnvi delivered a NEPM‑compliant preliminary site investigation and groundwater monitoring report in four business days to meet settlement and bank requirements for a petrol station expansion on the NSW South Coast.
Desktop (Phase 1) preliminary site investigation for a proposed child care centre in Sydney’s Northern Beaches. The desktop study identified low contamination potential from on‑site history but recommended targeted soil sampling and an asbestos hazardous‑materials inspection before council proceeds with a development application.
