Okay, before you can put up walls, you have to put everything in the walls that makes everything work, like electrical wiring, plumbing, and air conditioning ductwork. There are elves who do this for a living. You go to work in the morning. When you come home that evening, all this stuff has been stapled to studs and run over the rafters. And lots of little blue boxes sprout from the framing in strange places.
They even do showers stalls.
It is no fair that the crane to deliver the air conditioner came just as I had to go to work. I didn't get to watch!
How many men does it take to place an air conditioning unit? 5 - one for each side of the unit and one to drive the crane to place it on the roof.
Matt got to play the drills and dremel (wonderful, magical tool that lets you cut around the little blue boxes and other openings after the board is on the wall.). He got quite proficient at the whole lift and drill routine. Did you know there is a neat foot tool that you slide under the bottom edge of the wallboard and then you step on it and it pushes the board up and into place?
1 thunderstorm that showed us there were still leaks in the roof before the drywall went up.
2 different drills needed to properly do the job
3 steel tapes. They would congregate in odd places and then get moved back to where they would be useful.
1 dremel. See above comment. Rusty's had a neat attachment that kept the bit at the correct height while you drove it around the boxes. Or wrote out your name in Chinese in a chunk of wallboard.
1 arrow used to push fiber insulation behind the shower walls. Dad spent most of Friday evening and Saturday morning doing this.
upteen kazillion square feet of wall board hung.
