Environmental site assessments for Sydney property decisions
Phase 1 and Phase 2 investigations that help purchasers, vendors and developers understand environmental risk before a transaction or redevelopment decision.
A Sydney site assessment should answer the decision in front of the project team: whether a site history raises potential concerns, whether intrusive investigation is warranted, and what the findings mean for the intended use.
We structure the work in stages so desktop review, site walkover, sampling, laboratory analysis and reporting are proportionate to the site and the transaction or planning context.
Project context
- Property acquisition and divestment due diligence
- Brownfield redevelopment and change of land use
- Pre-development investigations
- Lender, purchaser and project risk review
How we work
- Phase 1 review: Review site history, surrounding land uses, setting and potential sources of environmental concern.
- Phase 2 design: Where warranted, plan sampling and analysis to test the relevant contamination hypotheses.
- Decision-ready report: Explain findings, limitations, land-use implications and proportionate next actions.

Frequently asked questions
- What is included in a Phase 1 environmental site assessment?
- A Phase 1 generally reviews site history, surrounding land uses, available environmental information and a site walkover to identify potential contamination sources and decide whether further investigation is warranted.
- When does a Sydney site need a Phase 2 investigation?
- A Phase 2 may be appropriate when the Phase 1 identifies a potential source or pathway that needs to be tested, or when the transaction, planning or risk decision requires intrusive evidence.
