I am trying to help-out our forming/framing crew owner here. Partly out of sympathy, because he is so dumb and disorganized, partly just to help him get his work done faster. He did some stair forming. Laid his form ply vertically, so it would be sandwiched between a block wall and the newly poured stairs. Instead of listening to our site forman, an placing strategic cuts in his form ply, he used full sheets. Then he left it for weeks, so the plywood could get nice and wet and swollen. It isn't coming out of there. We require that he cut off the plywood that extends out of the form, between the block wall, so there is at least a recess that we can caulk. We suggested using a reciprocal saw, and pulling, chiseling, or whatever means to get the remaining bits of plywood out. Do you guys have any other suggestions? If there was something like a large freud trim saw, that might work. He is working between concrete stairs and concrete block, so it is tough. Chain saw isn't going to work. He has several stair forms to do. Thanks for any tips or suggestions. it will reduce the whining I have to listen to.
