I just finished doing a quote on a big paver job of 7500 sq ft driveway. to take up and clean and relay and regrade, 1200 sq ft of which is new material as a border. I quoted the job to completely redo the base 24 inches deep, the 1200 sq ft of border stone which is unilock copthorne and unilock courstone mix. The guy already has two quotes to do the driveway. I presented him with the quote to completely redo and he almost crapped himself. I quoted at just over 80 grand. He told me i was quite a bit higher then the other guys. they apparently only quoted to take out, clean, and relay the original interlock, with adding 600 sq ft of border of unilock umbriano. These companies apparently came in at a quote of under $20,000.00 I almost lost my nuts when he said that. What do you guys think. I am supplying 100 bags of polymeric sand up to 20 yards of gravel for leveling 25 yards of #2 sand 600 ft of court stone interlock 650 to 700 ft of copthorne laid on a 45degree angle in between the double border court stone just going to level the current base without removing. re-use old edgers I am also putting one 65 sq ft star in the driveway and one smaller 35 sq ft star made from the same materials as the border. Pretty much they are offering the same as me except i am offering the extra interior border with the copthorne. no matter how i look at it i can only come up with a number of just over 40,000.00 Even if i only offer the single border instead of the interior border. i am pricing at just over 30,000.00 These are lowest prices i can come up with i don't even think these prices are high enough. If anybody can possibly explain why they would ever do this job for under $20,000.00 i would appreciate it.
