Squaring And Straightening Walls After Raising

If  the wall's exterior is to be sheathed after it is raised, it does not need to be toenailed to the floor after assembly unless it is to be squared before it is raised. A let in or temporary diagonal brace can be tacked to the wall after squaring. Tacking allows the wall to be adjusted after it is raised. After raising the wall, nail the bottom plate to the subfloor through the floor joists, then plumb, and square it and brace each corner to the subfloor. Two carpenters are usually needed. If the wall was not squared on the subfloor, it can be raised, plumbed and squared with a spirit level attached to a long straight edge. Plumbing the wall at two of the right angled sides of each corner will plumb and square the wall. Brace the corners of the  wall to the subfloor to keep it upright and plumb. Adjust the lower part of the corner braces after squaring. Use three spacer blocks and string to straighten the top of the wall. Brace the wall to the subfloor at each point the wall is checked and straightened if necessary. The braces will stay on until the wall has been sheathed, usually with plywood, and nailed to the other walls, plates, and floor or ceiling joists. Sheathing will keep the wall square. See figure 31. The golden section can be incorporated into the wall or some other part of the building.
