I need someone very good in Engineering mathematics
A new highway is to be constructed. Design A calls for a concrete pavement costing $7575
per foot with a 1212-year
life; twotwo
paved ditches costing $44
per foot each; and threethree
box culverts every mile, each costing $7 comma 0007,000
and having a 1212-year
life. Annual maintenance will cost $1 comma 7001,700
per mile; the culverts must be cleaned every threethree
years at a cost of $300300
each per mile.
Design B calls for a bituminous pavement costing $4040
per foot with a 66-year
life; twotwo
sodded ditches costing $1.551.55
per foot each; and twotwo
pipe culverts every mile, each costing $2 comma 1502,150
and having a 66-year
life. The replacement culverts will cost $2 comma 3502,350
each. Annual maintenance will cost $2 comma 7002,700
per mile; the culverts must be cleaned yearly at a cost of $235235
each per mile; and the annual ditch maintenance will cost $1.701.70
per foot per ditch.
Compare the two designs on the basis of equivalent worth per mile for a 1212-year
period. Find the most economical design on the basis of AW and PW if the MARR is 1010%
per year.
