woah...12K for a H slab?? seems like a lot..
lucky you got a second opinion...Im waiting for my site costs also and hope they are not more than 10k. We were told a H slab (which I am expecting our block will be) is about 6500.Hopefully itll come back at a M mod which is even better and only cost 1500. Dont wanna miss out on something else cause the site costs spiral out of control..
I know how you feel. Cant wait to get the tests done so I know the final amount of money we will have to borrow..
Good luck with it all
