iEnvi completed a preliminary site investigation (PSI) and soil sampling for a Sydney property intended for residential redevelopment. A 253‑page technical report and site history review concluded the site is suitable for residential use and suitable to support a development application.
iEnvi completed a 216‑page Preliminary Site Investigation and soil sampling program for a proposed Nepali place of worship in north‑western Sydney. The PSI found no evidence of contamination that would prevent the proposed use, and provides the documentation needed to support a Development Application where land history indicates only agricultural use.
Investigation and ASSMP for an industrial development in Hastings (Mornington Peninsula) including field pHF/pHFOX screening, ~50 samples from 24 bores, SPOCAS laboratory testing, PASS mapping and construction-phase soil and water monitoring to manage acid sulfate soil risk and meet Victorian requirements.
iEnvi supervised a 2019 resource-recovery program to reuse road asphalt millings as engineering fill for new sports fields. About 19,755 tonnes from 56 roads were reused under Recovered Aggregate Order requirements and assessed suitable for public open-space use.
iEnvi has undertaken soil vapour sampling, using the implementation of the ASC NEPM, to identify potential risks of vapour intrusion regarding human exposure on various sites.
OEMP for an auto vehicle storage and container-packing yard in Campbellfield, VIC. Practical controls for fire, noise, air, soil and stormwater risk, aligned with AS 1940 recommendations and Sustainability Victoria guidance.
A concise case study of a limited pre‑purchase soil investigation at an open car‑park in Rosehill NSW. Investigation identified historical fill with asbestos‑containing material (ACM), minor TRH and PAH in saturated soils, existing groundwater bores, and potential groundwater inflow to a proposed excavation pit. Practical risk management and next steps are summarised for developers and buyers.
Annual asbestos inspection of an electrical control room at a western NSW coal mine found asbestos-containing material in good condition. iEnvi managed a local contractor, reviewed sampling results and provided practical compliance recommendations.
iEnvi completed a 250‑page preliminary site investigation (PSI) and soil sampling program for a community group seeking development consent to use a western Sydney property as a place of worship. The investigation supported a successful development application.
iEnvi completed a combined preliminary site investigation (PSI) and geotechnical soil investigation for a proposed childcare development at Redbank Plains, QLD. Findings indicated negligible contamination suitable for childcare use while geotechnical issues prompted footprint adjustments to avoid subsidence risk. The DA was approved by Ipswich City Council.
