We started first thing in the morning by lifting off the beams to check the concrete in the perimeter piers, and ended having to add some more concrete to secure the bolts as the mix yesterday was too dry to properly fill in around the threaded rod.
We cut most of the plywood (or more accurately OSB/chip board) for the underside of the floor joists - part of the structural box that will make up the ground floor plane. We are using more concrete than we had wanted to, but it was a choice between more plywood or more concrete.
Pat had to leave at mid day, leaving Bruce to start building the panels for the ground floor. This was definitely a case where 2 people would have been 5 time faster than one.
We will build 27 panels for the ground floor, each consisting of 2 sheets of ply screwed to a frame typically consisting of 2 joists which are notched on one end to sit on a bearing piece that wil be bolted to the perimeter beam, as well as blocking. These panels will be constructed upside down to make it easier to screw the ply to the joists and will be flipped over and slotted into place with one end fixed to the beam and the other end cantilevered over the bearing walls of the cellar. One set of panels will extend from the front of the house, and another from the back, and then joined in the middle, and additional blocking added. A slightly complicated process but it allows us to secure the plywood to the entire underside of the house, without crawling underneath and messing around with the bearing walls.
