Today we kept on going with the nogs that we had started last week. We split into teams to get different jobs done, as we are pretty behind at the moment because of the weather.
Some of us, used the dumpy level to check the levels of the joists. Any discrepancies indicated areas that needed to be leveled out to be made plumb. Essentially this was where the joists met on the middle bearer and also the middle sections of each joist where there is a bow. Doing this, also indicated where there were problems with the bow of the wood, as it showed some had the bow down, instead of up. These had to be changed around, as otherwise it won't support the loaded dimensions as well.
A planer was also used in conjunction with a straight edge so that the joists and other areas were at the correct level. This is so when the particle board is laid it sits flat throughout out the whole floor area. Had to make sure that it was no more than 1-2mm lower than straight edge at all times, otherwise it only helps to cause discrepancies with the plumb of the floor, but in the opposite direction.
We also spent time to give extra bracing to the subflooring. Stainless steel plates were placed on every join of the laminated bearers (on both sides). These should be placed in the middle and have atleast 3 stainless steel nails on each side of the plate to keep it secure. We also put bracing on from the bearers to the joist, as in the past we have had issues with the bearers staying behind on the jack studs when it is removed to be transported off the site. Plates were also put on every joist join as well.
