Consultancy Software Training About Us


We offer a complete range of environmental site and due diligence audit services. We focus on ensuring that our client's goals are met in the most cost-effective manner possible, whether they are to acquire, lease, transfer, re-finance, re-develop or improve the value of commercial/industrial real estate.

Our EDDA's are carried out in a systematic manner and are divided into three phases that relate to varying depths of evaluation.

A Phase 1 Liability Assessment typically comprises site visits, records review, regulatory review, geologic and hydrogeologic review, report preparation and report review. It is performed to determine whether environmental contamination is likely to be present at a property which may result in future environmental liability.

Phase II Confirmation Sampling involves the use of limited site sampling to confirm or deny any suspected contamination identified in Phase I.

Phase III Site Characterisation is a comprehensive study to fully characterise the nature and extent of contamination at a property and any affected populations or environmental receptors. A phase III assessment typically comprises plan development, site characterisation, risk assessment, remedial technology recommendations, cost estimation, report preparation and report review. Phase III assessments are performed only after a Phase II assessment has confirmed that there is contamination at the site.

We recognise the importance of effective risk communication and therefore tailor our reports to the target audience, ensuring that the risks associated with a site are clearly presented and easily understood.

Audits can be performed on operational as well as decommisioned industrial sites. Costs are depend on the site’s area and complexity. Fixed price contract work can be arranged.
