iEnvi supported a Tier 1 contractor to deliver NBN trenching and pit works across Brisbane Airport precincts, managing PFAS and asbestos risk, enabling in‑situ waste classification and immediate backfill to meet Commonwealth safety requirements and avoid costly hazardous disposals.
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 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.
