Contract analysis scenario one—damages determination: Alfred and Barbara own adjoining farms in Dry County, an area where all agriculture requires irrigation. Alfred bought a well-drilling rig and drilled a 400-foot well from which he drew drinking water. Barbara needed no additional irrigation water, but in January 1985, she asked Alfred on what terms he would drill a well near her house to supply better-tasting drinking water than the county water she has been using for years. Alfred said that because he had never before drilled a well for hire, he would charge Barbara only $10 per foot, about one dollar more than his expected cost. Alfred said that he would drill to a maximum depth of 600 feet, which is the deepest his rig could reach. Barbara said, “OK—as long as you can guarantee completion by June 1, we have a deal.” Alfred agreed, and he asked for $3,500 in advance, with any further payment or refund to be made on completion. Barbara said, “OK,” and she paid Alfred $3,500.

Alfred started to drill on May 1. He had reached a depth of 200 feet on May 10 when his drill struck rock and broke, plugging the hole. The accident was unavoidable. It had cost Alfred $12 per foot to drill this 200 feet. Alfred said he would not charge Barbara for drilling the useless hole in the ground, but he would have to start a new well close by and could not promise its completion before July 1.
