Construction
of New Ship's Store (cont.')
With most of the walls complete, the roof was installed.
The building has a steel roofing system, but there is from six to eight inches of
insulation between the inner and outer layers of metal. The outer layer of metal
roofing was installed first, over insulation strips on the frames and purlins.
As the exterior layer of roof was completed, batts of
insullation were installed under the metal. Straps held the insullation in place
from below.
At the same time, windows were cut in and covered with
plastic and insullation. Exterior trim was installed and the building contractor started
installing siding on some areas of the building.
Exterior wall insullation was installed in a couple of days
by a separate contractor. This insullation was also covered by a plastic vapor
barrier. Once the roof and exterior walls were fairly well insullated, heat was
started inside the building. The floor at this time was still just crushed stone,
and had to be thawed out before it could be graded and the concrete floor poured.
Two giant salamander heaters ran for weeks. Fans on
the ceiling circulated air, keeping the warmth well distributed in the building, but for
the guys working on the ceiling it was still pretty warm.
During this time, plumbers and electricians routed their
pipes and conduits both under the floors and in the walls. They also "roughed
in" the boxes and fixture parts that would later be covered by plaster board or
concrete. The design of the building incorporated enough extra space in the
electrical and plumbing systems so that new systems can be installed without tearing out
walls or floors. Conduit runs were installed between the future electronics sales
area and the roof, for antenna and sensor installation. The entire facility was
wired for computer and telephone systems, too.
All of the original fill on the site had been replaced,
before the building was reassembled, with 3/4" stone fill. When the building
was enclosed enough, and warm enough, the fill was leveled, first with a bobcat, then by
hand. The remaining pipes and conduits were also installed at this time.
