iEnvi completed a confidential PSI and UPSS investigation at a commercial inner-Sydney property to define hydrocarbon impacts to soil, groundwater and soil vapour, and to quantify the likely remediation and compliance implications if the site is converted to residential use.
iEnvi carried out a preliminary site investigation at a mechanic workshop in Wynnum, QLD to support finance approval. Potential contamination sources were inspected and targeted soil sampling returned no detections of contaminants of concern, enabling the lender to approve the purchase. Practical ongoing management steps were provided to the client to minimise future contamination risk.
iEnvi completed preliminary soil investigations at multiple inner‑Sydney parks in early 2019. Hydrocarbons were detected in shallow soil at two parks, and targeted leachate testing demonstrated the hydrocarbons were immobile, allowing playground upgrades to proceed without further remediation or environmental management plans.
Targeted soil sampling at three sites identified shallow hydrocarbon contamination at two locations. iEnvi recommended a cost‑efficient program combining a biological treatment additive (S200 OilGone) with excavation and encapsulation to reduce health, ecological and transaction risk.
Shallow soil testing at a residential site in Morningside prior to construction of a childcare centre found concentrations below regulatory assessment criteria for human health and ecological receptors. Soil was considered low risk and no further action was required. Reuse options may now be considered prior to offsite removal.
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.
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.
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.
