A contractor signs a contract for the construction of a $150 million ship harbor expansion. Before the Notice to Proceed is issued, a hurricane passes near the area and substantially changes the shape of the sea floor. The contractor claims that different drilling and dragging equipment will be required for the changed shape and requests a bid price adjustment. The owner responds that the passing of a hurricane is common in the area, and therefore, the contractor should have included the event as a contingency cost in his bid. Who is right? How do you think that this real case was settled?
