I gave a rpice yesterday for a a small elevated patio and reatining wall. Customer thought price was really high. Keep in mind that the patio height will be about 3 feet above existing grade. Here is my breakdown. install retaining wall 3' high x 70' long (240 sq. ft.) includes base and backfill materials $15/sg.ft. 3600.00 install patio pavers 19' x 19' with semi circle end includes base material $10/sq.ft. 3750.00 Retaining Wall block (exact price dependent on customer choice) Approx. $13/sq.ft. 2535.00 Pavers (price on customer choice) Approx $2.5/sq.ft. 937.50 Installation includes base materials 9-10 tons paver base 6 tons clean 3/4" 2 tons sand Total $10,822.50 Excellent access from about 20-30' from driveway. Will have a skid on site. No digging concerns. Plenty of room for materials storage. Am I way off somewhere? Normally my bids are right inline with everyone else in the area. He claims he can show me a bid from two years ago for 6-7000. What do you guys think?
