ANALYSIS PROCEDURE

The alternative selected for investigation during the Phase B study

was designated by the project sponsors.

Cost associated with capital construction, right-of-way, operation

and maintenance, and property acquisition were developed from the

unit costs presented in Tables VI I -l and VII -2.

The impetus behind benefit/cost analysis is to determine the

relative economic merit of the proposed improvements.

This section presents the cost data used in the benefit/cost

analysis and displays in tabular form the results of this inves-

tigation.

B.

COSTS

An analysis of the costs associated with the proposed or planned

improvements is a vital part of the overall benefit/cost analysis.

Cost evaluation depends generally on six items: (1) Construction

costs based on the type of improvement and design capacity; (2)

required right-of-way and property acquisition (3) regular main-

tenance costs (4) engineering costs; (5) administrative and finance

costs; and (6) contingency costs.
