PurposeThe purpose of the AISC Certification Program for Steel Bridge Fabricators is to confirm to owners, the design com-munity, the construction industry, and the public that a cer-tified steel bridge

19、fabrication facility has the personnel, organization, experience, documented procedures, knowl-edge, equipment, and commitment to produce fabricated steel of the quality required for steel highway or railroad bridge construction.2. Program Scope and Fabricator eligibilityThis Certification Standard

20、for Steel Bridges offers assis-tance to steel bridge professionals, owners, general contrac-tors, and other interested parties in assessing fabricators capability to satisfy project quality needs. Specifiers of this standard are encouraged to evaluate fabricator capability independently, particularl

21、y with regard to project- or owner-specific requirements.The standard describes requirements for certification of facilities that fabricate and supply steel highway or railroad bridges. These facilities have quality management systems with defined functions and responsibilities.The quality managemen

22、t system of fabrication facili-ties (not products) is certified. The certification should not be understood as a product inspection of fabricated steel bridges. Certification includes all functions of providing steel bridge fabrication from receipt of contract through final delivery. The scope of th

23、is certification does not include design or erection. For bridge rehabilitation, the specifier is encouraged to consider on a project-specific basis the nature of the items being fabricated to determine whether this cer-tification is appropriate. Likewise, for pedestrian bridges the specifier is enc

24、ouraged to consider the structure type and loading to determine which is the most appropriate certifica-tion for a particular project.The scope of this certification does not extend to the application of complex coating systems as defined in AISC 420/SSPC-QP 3 Certification Standard for Shop Applica

25、tion of Complex Protective Coating Systems.The certification program is open to all fabricators of steel highway or railroad bridges, regardless of size and regard-less of AISC membership status.This standard, including its supplemental requirements, has three categories of certification: simple bri

26、dges, interme-diate bridges, and advanced bridges. Fabricators producing fracture-critical members, intermediate bridges, or advanced bridges shall be required to meet specific supplemental requirements.Simple bridges consist of unspliced rolled sections.Intermediate bridges are typical bridges that

27、 do not require extraordinary measures. Typical examples might include: (1) a rolled beam bridge with field or shop splices, either straight or with a radius over 500 ft; (2) a built-up I-shaped plate girder bridge with constant web depth (except for dapped ends), with or without splices, either str

28、aight or with a radius over 500 ft; (3) a built-up I-shaped plate girder with variable web depth (e.g., haunched), either straight or with a radius over 1000 ft; (4) a truss with a length of 200 ft or less that is entirely or substantially pre-assembled at the certified facility and shipped in no mo

29、re than three sub-assemblies.Advanced bridges are those requiring an additional standard of care in fabrication and erection, particularly with regard to geometric tolerances. Examples include tub or trapezoidal box girders, closed box girders, large or non-preassembled trusses, arches, bascule brid

30、ges, cable-supported bridges, moveable bridges, and bridges with particularly tight curve radius.3. referencesThe fabricator shall have the reference documents and stan-dards necessary to make personnel aware of work require-ments. References shall be consistent with the requirements of existing con

31、tracts and be readily available to those who need them.4.
