Concrete was supposed to go down yesterday but now not until tomorrow (Wednesday). They came out yesterday to check and lay down rebar. I get a message, hey we need an additional 12 yards of concrete. What the?? If they used all extra 12 yards that would mean my slab will be 8" thick! My excavator was steaming mad and said there is no way. What ended up happening is that they are ordered an additional 6.5 yards and will do a call back if more is needed. We shall see.
