CHAPTEE VI ESTIMATEP COSTS General . One of the prime requisites of a report of this type is the presentation of accurate cost estimates. In order to arrive at cost estimates that will com- ply with this criteria, it is essenti~l that all quantities be carefully com- puted and that every effort be made to assertain unit prices that will be applicable to this individual project. Many factors affect the bid prices that will be received from potential bidders. These prices may vary depending upon the magnitude of the project, the date of the bid opening, availability of materials, or the amount of work of similiar nature under construction in the general vicinity of the project and the various locations throughout the State. The unit prices used in this report are based upon the most recent construction bids available with allowances having been made for local conditions that may influence the cost of work. The basic. cost estimates were developed using 1981 prices which have been determined from experience which has been developed over many years in preparing estimated construction costs. A contingency factor, based on the unknowns involved, in the amount of 20% has been used. It must be realized that cost estimates can only be reflected over a compara- tively short time, due to the unstable. condition of labor and material costs. Accordingly, cost estimates shown herein should be considered valid for the near future only. . Time is a very important consideration if the estimates of project costs in this report are considered accurate. Time will be consumed by the following: review and approval of the Feasibility Study; time required to prepare and review and approve the Flood Study; time required to prepare and review and approve the design Plans and Specifications for construction. Three agencies will review in detail the Flood Study and the design Plans and Specifications, these agencies are: the Colorado Water Conservation Board; State Engineer's Office; and the Forest Service. From experience we realize that the "shelf life" and actual review time for the review and approval of the Flood Study and the de- sign Plans and Specifications takes at least four weeks each. With the anti- cipated winter weather conditions that could occur at an elevation of approxi- mately 76,000 foot elevation it's possible the project may not be constructed un- til 1982. Due to the potential delay an allowance for future cost escalations have been placed in the total estimated project costs. VI-I
