A small bridge is to be constructed at the site which you have analyzed. The bridge consists of two abutments and one intermediate pier supported by a total of 20 piles, each having a design load of 200 tons. The factor of safety to be applied is a function of the type of construction as shown below, along with cost information: Table 1: Required Factor of Safety and Cost for each Construction Plan Standard Load Test with WEA PDA (dynamic testing) with WEA WEA only Dynamic Formula Field Control FS = 2.25 FS = 2.75 FS = 3.0 FS = 3.5 Determine the most economical construction control plan for the pile foundation. Choose pre-stressed concrete pile, and vary the length and size incorporating the appropriate factor of safety. For the purpose of comparison, assume a cost of $85/LF for the pile material and construction. Complete the following table to determine the most cost-effective alternative.
