Economic Sustainability of Transportation Infrastructure Procurement: The Differing Site Condition Clause Debate as an Underlying Environmental Trigger to Cost Overruns
Abstract: Case law is rife with contractual disputes arising due to lack of adequate geotechnical risk containment during procurement. The use of a ‘Differing Site Conditions (DSC) clause’, implies that, in the event of encountering a subsurface/geo-environmental condition different from that which was indicated in the contract, the owner bears the additional cost for executing the work under such conditions. However, the literature indicates a divergence in industry practise, with some …
