The Differing Site Conditions clause is one of the oldest clauses used in construction contracts, having been created by the U.S. Federal government in 1926. It is generally accepted that the object of the clause is to transfer the risk of latent site conditions to the owner, thus enticing contractors to reduce their contingency cost at the time of the bid. The promise of the clause is that if the contractor encounters a “materially different” condition during the execution of the work, the owner will compensate the contractor for the resulting cost and/or time. For more than 90 years this standard clause has been used widely in both public and private contracts. Most practitioners in the construction industry think they know what the clause means and how it operates. But, in the words of one of the mid-20th century “deans” of construction law, Max E. Greenberg, “It ain’t necessarily so!” Over the years, the Courts and Boards of Contract Appeals have been slowly changing the interpretation of risk allocation under the clause. A series of Court and Board cases have increased the contractor’s risk concerning differing site conditions. This webinar will explore the changes in risk allocation.

Differing Site Conditions or materially different latent site conditions are often encountered on projects during construction. Whether natural or manmade, unforeseen conditions can wreak havoc on project costs and schedules. Standard contracts typically have a Differing Site Conditions clause intended to provide compensation to the contractor if such conditions are encountered. And yet, as old as this clause is, all too often there are disputes concerning whether the condition is materially different; whether contract disclaimers are enforceable; and whether the owner really owes time and money to the contractor. These disagreements most often arise due to a lack of understanding of how the Differing Site Condition clause is supposed to work. This webinar hopes to fill this knowledge gap concerning this type of claim for both owners and contractors.
