Hi everyone. This week one of my customers asked me for a bid on some dry stack walls and some flagstone. I have done the labor before, but never had to bid this type of work. Made a quick trip to the stone yard and asked some questions. I talked to a guy who told me a ton of fieldstone would cover 35 linear feet a foot high give or take. Somehow, I doubt that logic. (FYI, a ton of fieldstone at my cost will be $150.) A ton of flagstone, meanwhile, I was told will cover around 80 square feet. That seems short to me, too. (My cost, $260/ton.) So, the question is whether there is some way to roughly estimate how many linear feet a ton of fieldstone will cover? My plan is to bid this at 3x materials cost unless someone can show me the error of my ways. The idea of bidding it at an hourly rate + materials seems scary. Thanks in advance. I would appreciate any input as I am getting white knuckled over the whole thing.
