PART 3 - EXECUTION
3.1 FABRICATION: Fabricate structural framing in accordance with the
applicable provisions of the Specification for the Design, Fabrication, and
Erection of Structural Steel for Buildings as set forth in Part 5 of the
AISC "Manual of Steel Construction". Fabricate Pressure Vessels (Seam
Rupture Simulator, Void Simulator, Torpedo Hit Simulator) in accordance with
the applicable provisions of NSME Boiler and Pressure Vessel Code, Section
8, Division I except that ASTM inspection and certification will not be
required. Fabrication and assembly shall be done in the shop to
the greatest extent possible.
3.1.1 Welding: AWS D1.1; ASME Boiler and Pressure Vessel Code,
Section 8, Division 1; by certified welders, AWS B3.0. Grind exposed Welds
smooth as indicated, weld in a manner to prevent permanent distortion to the
connected parts.
3.1.2 Shop Painting: Except as otherwise specified, shop paint all
steelwork, except zinc-coated surfaces and steelwork to be embedded in
concrete or mortar. Surfaces to be welded shall not be coated within
1/2-inch from the specified toe of the weld prior to welding. Insure that
surfaces are thoroughly dry and clean when the paint is applied. Do not
paint in freezing or wet weather except under cover. Do not apply paint
when the temperature is below 40 degrees F, or expected to drop to 32
degrees F or below within 5 hours of completing the application, before the
paint has completely dried. Do not apply paint to steel which is a
temperature that will cause blistering or porosity or will otherwise be
detrimental to the life of the paint. Apply paint in a workmanlike manner,
and coat all joints and crevices thoroughly. Prior to assembly, paint all
surfaces which will be concealed or inaccessible after assembly.
3.1.2.1 Cleaning: Except as modified herein, blast clean surfaces in
accordance with SSPC-SP6. Surfaces that will be exposed in spaces above
ceilings, attic spaces, crawl spaces, furred spaces, and chases may be
cleaned in accordance with SSPC-SP3 in lieu of being blast cleaned. Wash
cleaned surfaces which become contaminated with rust, dirt, oil, grease, or
NFSS-T40
05150-5
other contaminants with solvents until thoroughly clean. Insure that
steel to be embedded in concrete is free of dirt and grease. Do not paint
or galvanize bearing surfaces, including contact surfaces within frictiontype joints, but coat them with an approved rust preventative applied in the
shop. Remove such coating just prior to field erection using a remover
approved by the rust preventative manufacturer. Insure that the surfaces,
when assembled, are free from rust, grease, dirt, and other foreign matter.
3.1.2.2 Pretreatment: Immediately after cleaning, coat surfaces
with a pretreatment coating conforming to Mil. Spec. DOD-P-15328 applied to
a dry film thickness of 0.3 to 0.5 mil or with a crystalline phosphate base
coating conforming to Fed. Spec. TT-C-490, Method I, except apply Phosphate
base coating only to blast cleaned, bare metal surfaces.
3.1.2.3 Priming: Prime treated surfaces as soon as practicable
after the pretreatment coating has dried. Except as modified herein, prime
with zinc chromate primer conforming to Fed. Spec. TT-P-645, applied to a
minimum dry film thickness of 1.0 mil. repair damage to primed surfaces with
primer.
