The boring data shown on the drawings for two bridge piers indicated the presence of boulders at the site. The successful contractor included in his bid the cost of cofferdams to surround the piers and to permit removal of these boulders. When work started, the contractor decided to try to get along without the use of cofferdams, and he succeeded. Does the contractor have to make a refund to the owner because of the decrease in the actual cost of doing the work? Explain.

Calculate the cost per cubic yard to place concrete using each of the alternatives described. The work in both cases consists of placing 140 cubic yards of concrete in footings. a. Using a crane and bucket at a price of $225 per hour, including an operator, with a crew consisting of 6 laborers, a cement finisher, and a foreman. The concrete will be placed in 7 hours using this setup, and transportation of the crane costs $390. b. Using a concrete pump at a price of $295 per hour, including an operator and a crew consisting of 5 laborers, a cement finisher, and a foreman. With this setup, concrete is placed in 6 hours and transportation of the pump costs $290.
