When lifting a wall section into position, the bottom of the wall can slip across the floor deck, and even fall off. If you are short on help, a solution is to position the section as it lays flat, then drive duplex nails (with two heads) through the bottom plate into the floor. The nails will bend as you raise the wall to a vertical position. After securing, pull out the duplex nails.
Use kitchen, bath, and other ventilating fans wisely. Turn these fans off as soon as they are no longer needed. In about 1 hour, these fans can pull out a house-full of warmed or cooled air.
