Walls and Trusses
At 0600, the crane arrived,
followed closely by Bob, and by 0630 some initial preparations had been
made (including moving some of the lumber piles in order to back the crane
closer to the slab). Before 0700 hit, the back wall had already been
raised into place, and temporarily braced. Two additional guys
arrived at about 7, and the four of them proceeded to make short work of
raising the remaining three walls. By 0800, all four walls
were standing and were partially secured in place.
wall was raised into place carefully by attaching straps to the crane from
the top of the wall (through gaps in the framing on the front and back
walls, through two of the window openings in the south wall, and attached
to temporary eyebolts secured to the top plate on the north wall).
Then, it was a matter of raising the top edge of each wall while guiding
the bottom plates into place. Once each wall was standing, it was
temporarily braced into place and secured, as applicable, to the adjacent
to see a series of photos of the walls going up.
Once all four walls were up and braced, the crew took a break and then got
to work on the trusses. There were 21 trusses to raise and brace
into position. Onto the first truss, they nailed two long sections
of 2x6 lumber, which extended about 8 or so feet beyond (beneath) the
bottom chord of the truss. With this extra height, it took some juxtapositioning
of the crane to get the first truss over the sidewall,
but once that hurdle was passed, placement of the first truss--the most
difficult, perhaps--went smoothly, except that the boom on the crane
couldn't extend quite far enough to reach the very back wall of the barn
and lift the truss and braced high enough above the wall to clear
it. Therefore, it just took a little fiddling to get the vertical
braces over the edge and secured to the framing beneath, thereby holding
the truss in position.
Once that was done, the
trusses came into place one by one, each one being nailed in place at the
sidewalls and secured with horizontal bracing about halfway up the slope
to hold them in the proper position. Other bracing was added along
the way as necessary. By about 1500, the work was complete--all 21
trusses were in place and braced securely enough for the moment, and the
weary crew packed up and went home, leaving me to pace around the barn and
stare in admiration, awe, and wonder.

Wednesday, September 3,
day in which the site went from nothing to a full-sized barn (if only in
framing) in only 9 hours, anything less was bound to seem
insignificant. Knowing full well the nature of construction, I was
prepared for this apparent slowing of the progress. Still, one
always hopes things can magically go faster.
this day, the extent of the progress was the completion of the sheathing
on the two gable walls, not including the gables. It didn't seem
like much, but of course moving and installing all that plywood is time
consuming and difficult. Bob has a great set of high-quality staging
and jack system that surely made the job easier, but it's still a big,
tall building--and sheathing isn't the fastest job in the world to begin

Gable Framing, Sheathing, and Other Details
a rainy day on Thursday (no work was done), Bob arrived alone on Friday
morning. This meant that there would be no major work done on things
like sheathing, but there was plenty that could be done alone in an
efficient manner. He began by setting up a taller set of jacks that
would enable him to reach the higher parts of the gable, and then set to
work on some cross-blocking between the roof trusses, gable framing (he
admitted that he should have ordered two gable trusses, which come with
all the appropriate framing installed 2' on center), and
other smaller jobs. This stuff all needed to get done, of course,
and sometimes it's just good to have a day dedicated to knocking off that
annoying punch list. Next week, work in earnest on the roof
sheathing and shingling can begin. It didn't look like much, but
progress is progress!
anchor bolts, installed after the walls were standing, consist of hardened
steel bolts and an insert. Holes are drilled in the framing and into
the concrete, the bolts (and inserts) are installed, and the nuts
tightened. As the nuts are tightened, the action expands the insert,
firmly securing the fixture in place.
