The Problem:
A large warehouse and logistics facility in Brisbane’s south was preparing for a new lease. The owner wanted a clear, defensible snapshot of current contamination conditions before handover. The site includes extensive hardstand, warehouse space, a truck wash bay, cold storage, and above-ground diesel and AdBlue storage, so the baseline needed to consider petroleum risks, storage areas, and high-traffic zones.
Project Summary:
iEnvi designed a smart, construction-friendly baseline that keeps cost and time sharp while collecting the right evidence. We started with a preliminary site investigation (PSI) using council and state registers, historic aerials, Before You Dig Australia data, and a detailed site walk to map potential hotspots like fuel storage, washdown, loading docks, and service corridors. We then cleared services using GPR and completed targeted soil investigation with environmental drilling at eight locations to depths up to about eight metres where practicable.
We collected sixteen primary samples plus QA QC replicates for NATA laboratory analysis of total recoverable hydrocarbons, BTEXN, PAHs, eight metals, and asbestos in soil. If groundwater was encountered during drilling, grab samples were to be collected to screen for groundwater investigation needs. Results and observations were rolled into a crisp Baseline Contamination Report signed by a Certified Environmental Practitioner Site Contamination specialist.
Solution & Benefit:
The outcome is a confident baseline that protects both landlord and tenant. It supports clear lease terms, smarter maintenance planning, and faster approvals, while reducing uncertainty around petroleum handling zones and heavy-use areas. iEnvi’s approach blends contaminated land investigation with practical site knowledge, delivering PSI, soil investigation, environmental sampling, and contingency pathways for groundwater investigation if needed. The result is low drama, high certainty, and a clean starting line for operations.
