In this case, I was shutting up Sandhill's new 12,000 gallon cistern, which involved pouring 4.75 cubic yards of concrete. The trickiest part was getting the forming right over a rectangular hole that was approximately 8'x25', so that the concrete went where we wanted it—and stayed there while it cured. As that amount of wet concrete weighs something north of a ton, you don't even want to think about the mess we'd have had if the forms had failed and the concrete slumped into the cistern. "Dismay"is not even in the same solar system as the emotional response that would have ensued. Although I had configured the shoring entirely with wood—something I was doing for the first time—everything held and the pour went smoothly (if you don't count Sandhill's pet kitten who mistakenly thought it would be clever to jump onto the wet concrete, and who realized immediately that something was very wrong).
Afterwards, the driver of the concrete truck (Dennis) admitted that he was worried about the forming holding up to the task. As there is no end of the amateurs buying ready-mix for backyard projects, you have to assume that drivers see just about everything, and Dennis had been delivering concrete for at least a decade. When he complimented us on the stoutness of our forming, I knew it was because he was not originally confident that we knew what we were doing. And so, in turn, I complimented him on keeping that opinion to himself until we were done. Whew.
While there is still be a good bit of work left before we can start capturing rain from the roof, the hard parts are now done and that was the bulk of my assignment. In the days ahead I'll oversee the wiring and the installation of the submersible pump, and advise on how to handle the overflow and the best way to connect the guttering to the cistern intake, yet these oddments are relatively straight forward and it feels good to have honored my commitment to build Sandhill a cistern—something I promised to do when I left the community last Thanksgiving.
Noticing how sore my back is today I'm wondering how much it makes sense to undertake this kind of work for anyone in the future. While it's never been easy for me to accept physical limitations—especially for things I used to be able to handle in stride—it's all the harder when I feel my knowledge about how to do things and my understanding of good technique have never been greater. Nonetheless, it may be time for me to put on lid on heavy construction. Sigh.
Maybe in the future I can be the guy who rescues the mischievous kittens and redirects the ill-disciplined dogs. Kind of like a New Age Walmart greeter.
