Two delivery methods have been proposed for a standard delivery method for new bridge constructions in Oregon to overcome traditional design-bid-build models that do not adequately account for site conditions and constructability, and often lead to additional expenses. One alternative must be selected to represent the delivery method specified in the RFP. Based on data from recent bridge construction projects of comparable size, we can estimate the savings from reduced redesign costs, risk management costs, and overhead costs during the life of the construction contract over the traditional delivery model. The estimated costs of a 18-month contract are the following: Alternative Construction manager /General contractor Design-Build Preconstruction and design costs $80,000 $90000 Monthly savings $4000 $6500 Project life, months 18 18 Which alternative should be selected based on the future worth method? Use a MARR of 4%, compounded monthly. Assume other benefits and costs are negligible.
