This CLE webinar will take a close look at litigating differing site conditions claims in construction projects. The panel will examine under what circumstances these claims may arise, what factors make for a successful claim, and available defenses. The panel will also address how to mitigate the risk of differing site conditions claims, including through carefully drafted contractual provisions.

Description

A differing site conditions claim may arise in a construction project when an unexpected and unknown physical condition is encountered in the performance of required construction work that differs materially from either the conditions indicated in the contract documents or from the usual conditions that an ordinary, prudent contractor would expect to encounter performing similar work in the same general area of the project. A differing site condition will often cause the contractor to be delayed or to incur additional costs, giving rise to the claim.

Construction litigators, whether representing subcontractors, contractors, or owners, should understand what factors make for successful differing site conditions claims and how to best defend against such claims. Additionally, counsel should know how to mitigate the risk of these claims, including through carefully negotiated contractual provisions to protect their clients' interests.

Listen as our expert panel examines litigating differing site conditions claims in construction projects, available defenses and litigation strategies, and how to mitigate the risk of these claims.
