I have a homeowner's association that wants a price on installing rip rap stone around a retention pond. See if you think my price is in line - never have done this type of job before. Pond is 1080 feet around, figure to put stone out six feet. 6'X1080'=6480 sq.ft. Stone covers 35sq.ft. per ton=185 tons. I can get stone for $12.75 per ton +40% mark up=17.75 per ton. Stone - $3283.75 Equip. rental - 2 skidsteers - $700.00 (2 days) Weed barrier - $444.00 Labor - $2000.00 Total job - $6427.75 Does this seem in line? Figure me plus one other guy should be able to do this in two days, does this seem close? Thanks in advance.
