I've read quite a bit on here about hitting rock during construction and how it can affect not only cost, but original plans as well. I live in Tx, south of Dallas, and am fairly certain that we will encounter some rock. Is there anything you can do to discuss the possibility with the PB beforehand? How much does this add to the cost and why?
Our entire subdivision is built upon a clean-fill lot, and if the clean fill lot across the steet is any indication, there will be huge chunks of rock and concrete under the dirt. I'm a little wary now. I hadn't even considered this to be a snag in the process until reading this forum...which has been INVALUABLE to me in this pre-pre-planning stage!
