RPS Health Safety and Environment was commissioned by an international purchaser to undertake Phase 1 Environmental Liability Review of 10 Hilton hotels in Europe and RPS commissioned CSD ENGINEERS SA for the audits in France, Switzerland, Luxembourg and Germany. The principal aim of the review was to determine whether there is potential for pollution or other environmental impacts to be present which would significantly give rise to the risk of significant environmental liability or may cause a significant depreciation of the building price.
