Contamination Valuation
Property valuation where environmental contamination affects market value.
Who we work with
Owners, purchasers, lenders and legal advisers need valuation advice when environmental information may affect a property’s marketability, use or value. Our role is to analyse valuation implications using specialist evidence.
When you need us
Environmental conditions can influence a property’s use, marketability and value. The appraisal draws on the environmental information available for the assignment.
What we do
Consider remediation information and restrictions relevant to value
Analyse market evidence and the effect on the property interest
What you receive
We explain the valuation implications and reliance on specialist information. Environmental investigation and remediation advice remain with the relevant technical professionals.
What we need to begin
Provide environmental reports, available remediation estimates, restrictions, property plans and the transaction or valuation purpose. Identify who prepared the technical information and any uncertainties or further investigations underway.
Related assignment
A related land exchange appraisal differentiated parcels with development potential from environmentally constrained lands. It illustrates the need to match market evidence to property constraints; the published assignment does not document contamination or remediation valuation.
Questions & answers
Does gsi investigate contamination?
Our service is valuation. Environmental investigation, risk assessment and remediation advice remain with qualified environmental specialists whose findings inform the appraisal.
Is the value impact simply the remediation cost?
That should not be assumed. The valuation also needs to consider the property interest, use restrictions, timing and available market evidence, with the reliance on technical information stated clearly.
Can work begin before all environmental studies are complete?
An initial scope discussion can identify the missing information. Any valuation prepared with unresolved conditions needs clearly defined assumptions and limitations, and later findings may require reassessment.
