the structural steel to be furnished for the
project. The requirement for AISC fabrication plant
certification may be deleted at the discretion of
the designer. This decision will be based on the
complexity of the design and the criticality of the
connections. If moment connections are involved,
AISC certification is recommended. The quantity of
structural steel in the project should be a point of
consideration. The certification categories, as
defined in AISC FCD, are:
a.
Conventional Steel Building Structures
b.
Simple Steel Bridge Structures
c.
Complex Steel Building Structures
d.
Major Steel Bridges
e.
Metal Building Systems
f. Supplement: Auxiliary and Support Structures
for Nuclear Power Plants - This supplement,
applicable to nuclear plant structures designed
under the AISC Specification, but not to
pressure-retaining structures, offers utility
companies and designers of nuclear power plants a
certification program that will eliminate the need
for many of the more costly, conflicting programs
now in use.
**************************************************************************
Fabrication shall be in accordance with the applicable provisions of AISC
316. Fabrication and assembly shall be done in the shop to the greatest
extent possible. The fabricating plant shall be certified under the AISC
FCD for Category [_____] [Supplement] structural steelwork. Compression
joints depending on contact bearing shall have a surface roughness not in
excess of 13 micrometer 500 micro inches as determined by ASME B46.1, and
ends shall be square within the tolerances for milled ends specified in
ASTM A 6/A 6M. Structural steelwork, except surfaces of steel to be
encased in concrete, surfaces to be field welded, surfaces to be
fireproofed, and contact surfaces of friction-type high-strength bolted
connections shall be prepared for painting in accordance with [endorsement
"P" of AISC FCD] [_____] and primed with the specified paint.

NOTE: Consult with the structural designer. Use
AISC 316 and AISC 317 when allowable stress is used
for design, and use the AISC 325 when the load and
resistance factor is used for design. Most
designers are using AISC 316 and AISC 317.
**************************************************************************
Runway rails and beams shall be provided in accordance with [AISC 316and
AISC 317] [AISC 325] and CMAA 70, except that in case of conflict, the
