EXECUTION
3.1
INSPECTION
Check concrete dimensions, anchor bolt size and placement, and slab
elevation with the metal building manufacturer's templates and drawings
before setting any steel.
3.2
ERECTION
Erect in accordance with the manufacturer's approved erection instructions
and diagrams. Correct defects and errors in the fabrication of building
components in a manner approved by the Contracting Officer. If defects or
errors in fabrication of components cannot be corrected, remove and provide
nondefective components. When installing wall and roof systems, install
closure strips, flashing, sealing material, and other accessories in
accordance with building manufacturer's instructions to provide a
weathertight system, free of abrasions, loose fasteners, and deformations.
After erection is complete, repair and coat abraded and damaged, primed or
factory-finished surfaces to match adjacent surfaces.
3.2.1
Dissimilar Materials
Prevent direct contact between aluminum surfaces, and ferrous or other
incompatible metals, by one of the following methods:
a.
Paint the incompatible metal with a coating of manufacturer's
standard heavy-bodied paint.
b.
Paint the incompatible metal with a prime coat of corrosion
inhibitive primer followed by one or two coats of aluminum
metal-and-masonry paint, or other suitable protective coating,
excluding products containing lead and chromium pigmentation.
c.
Provide an approved nonabsorptive gasket.
d.
Apply an approved calking between the aluminum and the
incompatible metal.
If drainage from incompatible metal passes over aluminum, paint the
incompatible metal by method (a) or (b). Paint aluminum surfaces in
contact with concrete or masonry materials by method (a). Paint green or
wet wood, or wood treated with incompatible wood preservatives, by method
(a) or use two coats of aluminum paint.
3.2.2
Rigid Frames, Bases, and Sill Members
Brace frames as necessary to ensure safety. Set accurately, using a
nonshrink grout to obtain uniform bearing on the concrete and to maintain a
level base line elevation. Separate leveling plates under column base
