Here's what one 7 yard load looks like on the ground. They could have brought in more per truck, but kept it to only 7 yards per load to prevent possible damage to the 600' driveway.
They worked very well as a team and moved along a lot faster than I expected. They were careful to check for the rebar height reference mentioned earlier. Total pitch from back to front of slab is 1-1/2".
Working around the thickened footer edge they constantly banged the forms with hammers, etc., to settle the concrete and get a nice smooth side on the slab with minimal air voids.
Decided to modify our slab design at the side overhead door. Originally, I was going to just hold the apron height to the top of the lowered 5/4" PT board break. The head mason suggested 'cutting in' to the slab as pictured for even better water control. I like it.
In fact, it ended up being just about 1 yard larger than originally estimated. I know this because, after dumping 21 yards, they were 1 yard short! #%@!*&%!
