Karen hired our favorite tree man, Will Pote, to have the large african
tulip tree cut down in front of the house, it was a dirty and trash producing
tree. We started clearing the plantings that fronted our entry stairs and
front lanai. The before picture is shown at right. Below is the cleared
front deck at the beginning of construction, with Babu, me and Babu's assistant
Michael Karl.
The first effort was removal of the front deck. This is shown in the next
photo.
After
that we formed the footings on which the Pavilion's foundations would rest.
We added much #4 rebar and tied it together. This included vertical bars
that would be incorporated in the four concrete block foundation walls
and the six concrete block piers. I used walls to stiffen any shear loading
introduced by earthquake tremors, quite prevalent here in Hawaii. Each
wall ended at Pavilion corner anchor bolts with four piers completing the
12 necessary anchors.
Two intermediate piers supported the midpoint of the two transverse beams
that supported the 2x8 floor joist system.
We brought a transit mix in
to pour the four yards of concrete needed to fill the forms with the truck
backing down the driveway onto our front lawn so that the chute could hit
all the form cavities.
After
pouring the forms on Friday morning, a mason team led by Jeff Crone spent
Saturday erecting the block foundations. We next set about locating the
12 perimeter anchor bolts that would produce the final geometry of the
building. Since all the parts were pre-cut, and the 1/4 inch welded steel
corner brackets, 12 in all, produced both floor and column geometries,
their location vis a vis the anchors that were to locate and hold them
to the foundations was critical in insuring the parts would fit in their
final assembly.

By the middle of week three
we were ready to bring another transit mix with about three yards of concrete
to the site. This time the lumber we had unloaded from the container blocked
the end of the driveway so we had to wheelbarrow the cement to the block
walls. For this we assembled a crew that included Eddie, Jerry, Joel, Jan,
Babu, Michael, Karen and I. We took turns filling wheelbarrows , wheeling
them to the site, dipping buckets in the wet cement and pouring the contents
into the block cavities. We did the job in about an hour. We used a triangular
wood frame gage that rotated around a center pivot to locate the 12 anchor
bolts. You can see the anchor bolts in the photo of the pour crew above.
We next cut each of the 12 4x8 perimeter beams and using another gage pivoted
at the centerpoint, arranged the beams and the welded steel anchor bracket
around this center. The anchor bracket, shown at right, is fastened to
the concrete walls and piers by the embedded anchor bolts and holds the
two adjacent perimeter beams in place while presenting a vertical fin onto
which a slit in the main building columns fits and is bolted, so their
location is critical.
.
Once
the perimeter beam had been located and fastened down, the two main transverse
floor beams were added and the 2x8 floor joists were nailed in using galvanized
hangers. As you see we also framed the floor back to the front entrance
of the dome home.
