FISCAL, LEGAL AND ADMINISTRATIVE COSTS

Information obtained from the Denver Water Board and the ASCE

Consulting Engineers Manual ll5 resulted in assigning a nominal 8%

of construction costs (defined as construction cost plus mobil i-

zation and contingencies) to each improvement to provide for

fiscal, legal and administrative costs. These costs are associated

with the funding and implementation process requirements which most

flood control projects must go through before becoming a real ity.

ASCE Manual 45 states the following: "The item of contingencies varies

with the degree of completeness of the Engineer's report. Usually it

should be included in preliminary estimates at from 10 percent to 25

percent of the Engineer's construction cost estimate."

The following is a description of each column heading in the Benefit/

Cost display presented in Table VII 1-4.
