A new highway is to be constructed. Design A calls for a concrete pavement costing $90 per foot with a 20- year life; two paved ditches costing $3 per foot each; and three box culverts every mile, each costing $9,000 and having a 20- year life. Annual maintenance will cost $1,800 per mil e; the culverts must be cleaned every five years at a cost of $450 each per mile.
Design B calls for a bituminous pavement costing $45 per foot with a 10- year life; two sodded ditches costing $1.50 per foot each; and three pipe culverts every mile, each costing $2,250 and having a 10 -year life. The replacement culverts will cost $2,400 each. Annual maintenance will cost $2,700 per mile; the culverts must be cleaned yearly at a cost of $225 each per mile; and the annual ditch maintenance will cost $1.50 per foot per ditch.
Compare the two designs on the basis of equivalent worth per mile for a 20- year period. Find the most economical design on the basis of AW and PW if the MARR is 6% per year. (Note: assuming cleaning also occurs at the end of the life time)
note ;
1:comparision is based on 1 mile.
2:1 mile = 5280feet
for this problem:
a: Develop the cash flow table for each design
b:set up the cash flow equation but do not perform the numerical computations.
