Looking for advice on building a concrete slab

I operated a concrete pump very similar to the one in the video when I was at SLC6 at Vandenberg AFB. No **** .. It's given name was Putzmeister and built by Schwing. My supervisors were really jazzed when California Builder and Engineer Magazine came out to do an article on the Shuttle Launch Complex. They took rolls and rolls of film. On the cover of that month's issue, there I was in my railroad striped bib overalls, hard hat, ZZ Top cheap sunglasses, remote control for the pump boom hanging around my neck, and standing on top of the cab pumping concrete. Superintendent calls me to the office when he got his copy. He just shook his head and laughed ":wtf: were you thinkin'?" he said. "Craig they were down in a hole and it was the only place I could watch them from.":lol:
