My goodness that looks like miserable work with the grinder. That is a lot of material to remove, given the difficulty of removing it. I very much appreciate you providing this forthright demonstration of the necessity of forming rigorously and robustly to prevent having to perform this kind of remediation work. The formwork I have undertaken to date has been orders of magnitude lesser than that you have done building this house, and I presently don't have any intentions to dramatically increase the volume of the forms I employ. Even so, it is quite cautionary, as the impulse to be stingy with formworks is incessant.

Thanks!
