iEnvi supported a Tier 1 contractor delivering NBN trenching and pit works across a major Brisbane infrastructure precinct, managing PFAS and asbestos risk with in‑situ waste classification and immediate backfill to meet Commonwealth safety requirements and avoid costly hazardous disposals.
iEnvi managed in‑situ abandonment of three underground storage tanks at a commercial property in the Wide Bay region, QLD, using foam filling to avoid structural impacts. Work complied with AS4976‑2008 and included guidance on validation groundwater monitoring and UPSS completion to progress removal from the QLD Environmental Management Register.
Case study: CEMP, ESCP and VMP prepared by iEnvi for a regional council to manage vegetation clearing, earthworks, acid sulfate soils, fauna risk and sediment during construction of a sports complex in South East Queensland.
A 2020 preliminary assessment by iEnvi identified microbiologically influenced corrosion (MIC) risk for planned pipeline works and staging areas on the Mornington Peninsula, recommending targeted metallurgical and microbiological follow-up to protect assets and reduce failure risk.
iEnvi completed an in‑situ waste classification and Excavated Natural Material (ENM) assessment for a Southern Highlands council road upgrade. Of 20 samples collected at 30 m intervals, 17 met ENM criteria, two were restricted solid waste and one was hazardous — enabling reuse of most material and avoiding excavation‑stage delays.
iEnvi updated the ESCP for a State Significant development in the Mornington Peninsula using MUSIC stormwater modelling and IECA-aligned erosion and sediment controls to reduce construction-phase sediment risk and support regulatory compliance.
Two coatings manufacturing sites in Victoria and Western Australia were assessed by iEnvi through preliminary site investigations (PSI) to identify contamination risks, regulatory implications and recommended next steps for acquisition decisions.
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 eastern Brisbane, QLD to support finance approval. Targeted soil sampling returned no detections of contaminants of concern, enabling the lender to approve the purchase. Practical ongoing management steps were provided 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.
