CHAPTER V

ESTIMATED COST

Cost of Construction

Unit construction costs were derived using construction costs of
related projects in the area. Table 11 gives unit costs and total cost
for each item of construction as of fall 1979. Projected construction
costs are given for 1980 and 1981 to show cost escalations due to
possible delay in award of the construction contract. Escalation fac-
tors were detenni ned usi ng a graph of "Colorado Buil di ng Construct i on
Cost Increase Averages" for 1967 through mid-1979 and projected to
1985.

The majority of cost for this prOject is for furnishing and installing
pipe. rxcavation conditions and pipe quantities have been established
with reasonable accuracy, thus a minimum contingency factor of 15
percent can be applied. No extra costs for right-of-ways is expected
because all pipe will be installed within existing street rights-of-
way. An increase of 10 percent is added for engineering and design.
"Summary of Estimated Project Costs" is given in Table 12 including
engineering and contingency.

Fund Requirement Schedule

The estimated construction time is 6 months and the estimated design
time is 6 months including contract award. All funding will be needed
for the year in which the construction contract is awarded. 1980 is
expected to be the year in wh i ch project fundi ng is requi red assumi ng
no delays.
