More Beams and Another Temporary Floor
As the drawing shows, the second story west wall will be suspended over the master bedroom on beams. Their construction using LVLs was not unlike that described in a prior post. Once the beams were in place, I could then fill in with a temporary floor the space between the new beams and the permanent floor such that the entire second story now had a floor of some kind on which to work safely while building the
exterior walls and the second story roof.

Fortunately, I have enough lumber salvaged from several tear-downs to frame out the temporary floors. I screwed down 1/2' plywood sheathing as the floor surface then painted it with exterior stain in order to protect it as much as possible since the plywood is not intended for exterior use. I am hoping to be able to recycle it or sell it on Craigslist when the temporary floors are removed.
The plans specified a beam comprising two LVLs fastened together but, since the exterior wall resting on it will be 15" thick to match the other truss walls, I installed a third LVL such that the outer edges of the two beams were 15" apart. Then I covered the beams with subflooring to add rigidity.

Stops for Wall Raising
In order to add a measure of safety for an eighty-something, agility-challenged DIYer, I added a couple of safety ropes around the periphery of the second story. However, the main purpose of the 2x4s supporting them is to act as stops to keep the second story south wall from slipping off the edge when it is raised. Consequently, I used construction screws to fasten the supports more securely than could be done with nails or drywall screws. And I inclined them slightly outward at the top to be sure they would be out of the way of setting the wall later.

As described in the next post, the wall was controlled with ropes during raising and the stops were superfluous. But the ropes proved invaluable as I assembled the wall on the floor only a few feet from the edge. The ropes would have stopped, or at least, slowed any falls but I am inclined to think that their presence was more psychological than physical. After they were in place, I could relax and work near the edge instead of being preoccupied and overly cautious about falling.
