Step 7: Framing and assembling the walls
Once your starting wall is assembled on the ground (I started with the East wall below) you will want to move it out of the way and begin assembling one of your walls that is at 90 degrees to the starting wall. I next built the North wall in order to get the window opening out of the way. Build that wall in the same fashion as discussed in the framing basics step. You should save the wall with the large overhead door opening for last so plan accordingly.
Once two walls are built you will need to get a group together and lift the first wall onto the anchor bolts. Before you put the wall on there, get out the rolls of sill seal foam and roll it out on the slab/block and punch the anchor bolts through it. Run this foam around the periphery of your wall and then place the first wall over the anchor bolts. Hold it in place and thread some of the washers and nuts on the bolts. While someone holds the first wall, bring the second wall into place on the slab/block and put it over the corresponding anchor bolts.
With both walls swaying in the wind, nail them together at the corners, being sure to match up the edges as shown in the corner diagram. These nails will not hold up the wall well so you will need to get on a ladder and add a corner brace across the two top plates. See the sketch below, where there is a 2x4 nailed across the two wall top plates and another 2x4 nailed to an upright stud to brace the wall against the slab. Also visible is the course of block running around my slab. With the 8" high block, the three top plates and the 8' studs the "ceiling' in my garage is about 9'. If you do not plan on or require a course of block, then you might want to consider using studs longer than 8' to give you more headroom.
With two walls up, repeat the process on a third wall. You should do the wall with the large overhead door opening last since the header beam will be very heavy and thus more dangerous to install. This wall will be covered in the next step.
One last thing is that you must post your permit at the jobsite. You can put it in the window on your existing house until there is a structure to nail it to on the new building but it needs to be visible.
