Steve,
I am going to go out on a limb and say that this scenario does not happen too much, but let's say (tell me if I am wrong with my calculations here) this course was in Minnesota, your'e looking at about 100 acres of actual golf course turf, fairways, roughs, bunkers, greens, etc. (100 acres is just for a number to estimate by). A foot of sand over 100 acres is approximately 161,500 cy, now if the guy wants the job bad he can get the sand for maybe $2.00-$5.00 yd, for river sand, providing the USACOE will permit this much sand at one time, and ends up placing it for maybe $5.00-$10.00 yd, so now you are looking at $7.00-$15.00/yd and probably alittle higher, but 161,500 cy * $15.00/yd = $2,425,000. Now Steve remember in an ideal situation the heavy earth contractor, depending on how close the sand source is could probably get the material for "dirt" cheap, it ends up being the placement costs that get expensive, in my experience anyways. Hope that helps.
