Abstract: Principal factors involved in the design of drainage structures include hydrology, soil conditions, material strength, material durability, cost, and type of facility being drained. Although not necessarily overriding, the cost is often one of the most important factors. This cost should be the total, overall cost of the alternative over its projected life or life cycle cost (LCC). Unless the LCC is considered over first cost, the owner cannot be assured of receiving maximum value for his construction and maintenance dollars. Except for determining a service life for the various types (materials) of drainage structures, the procedures for LCC analysis are well established. LCC based economic studies are an integral part of the complete design process and are a requirement specified in Technical Manual 5-802-1. AR 11-28/AFR 178-1 gives the basic criteria and standards for economic studies by and for the Departments of the Army and Air Force. The guidelines presented in Part II of this report can be used to estimate the service life of a particular design or ensure a 50-year service life. Thus, the procedures for economic analysis described in Technical Manual 5-802-1 can be used to determine LCC. The alternatives can then be nrder ranked based on LCC, and the best design can be rationally and confidently selected.
