The increase in the amount of actual bid items constructed over the original bid amount
resulted from the need for additional 18 -inch storm drain and concrete drainage Swale
exceeding the bid item quantities. The final overall construction cost including change
orders was 15.9 percent over the original bid amount.
Five change orders totaling $66,135.70 were issued to complete the project. They were

abandoned waterline.

catch basin, splash wall, fee payment to Southern California Edison, and
miscellaneous items.
