This is a top-down view of the foundation wall forms - you can see the wood panels inside that will be the window openings on the South wall of the lower level and the rebar lattice.
Mr. Obrien showed up with the Putzmeister concrete pumper truck to get the concrete from the cement mixer to the foundation wall forms. The extended boom is shown below.
They had to maneuver the boom around the big pine tree on the NE corner of our lot. Not much room between that pine tree and the cottonwood in the neighbors' yard, but they didn't snap a branch. Pretty good Putzmeister handling, if you ask me... The really cool part of it was that the controls were in a remote control box that an experienced video game player operated. Mom & Dad, remember the time I had to write 10 reasons why I should be allowed to play video games? Well I didn't know about this one, but it would have been another good one to add to the list.
The cement mixers just backed up to this grate mounted on the back of the Putzmeister and poured the concrete into it. We used the maximum percentage of Fly Ash we could, which is a byproduct of burning coal. That does two good things - it keeps it out of the landfill and also stiffens the concrete.
This is a shot of the first of the 3 cement mixers that came to dump their cargo into the Putzmeister...
