Categories of AISC Certification


Building QMS Certification
This category uses the Certification Standard for Steel Building Structures and additional criteria uniformly to all building fabricators, regardless of size and complexity of project. AISC believes there is a basic level of quality that all fabricators need to maintain regardless of company size or shop capacity. The Building Standard and additional criteria place equal emphasis on all aspects of the fabricator’s business processes.

Bridge QMS Certification - Currently, this category is in the process of transition. Beginning on November 1, 2012 for applicants and July 1, 2013 for certified participants, this category will be based on the new bridge standard, AISC Certification Program for Steel Bridge Fabricators—Standard for Steel Bridges—2011 (AISC 205-11). The new Standard and additional criteria will supersede the current “Simple and Major Bridge Checklists” as part of an ongoing transition effort by AISC to a system-based approach to quality management. The full transition will be completed on July 1, 2014, and after this time, Simple Bridge and Major Bridge Checklist Categories will no longer be valid.

Categories, as defined by the Bridge Checklists:

  • Simple Steel Bridges - This category is appropriate for unspliced rolled beam bridges. Simple Bridges can be short, single span highway overpasses. These projects may interface with contracts for state transportation departments.
  • Major Steel Bridges - This certification is typically specified for bridges that have welded and bolted splices in multi-span projects. The projects include both rolled beams and built-up girders. Facilities should be capable of executing a typical three girder lay down and full assembly. The majority of these projects comply directly with state transportation departments' provisions. Companies certified for Major Steel Bridges are also automatically certified for Simple Steel Bridges.

Categories, as defined by the Bridge Requirements & Standard:

  • Simple Bridges consist of unspliced rolled sections.
  • Intermediate Bridges - are typical bridges that 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 straight 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
  • 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 bridges, cable-supported bridges, moveable bridges, and bridges with particularly tight curve radius

Standard for Bridge and Highway Metal Component Manufacturers (CPT)
This category is modeled on the Building Category but describes certification requirements for facilities that manufacture and supply specific components, composed primarily of metal to bridge and highway construction projects. Certification is appropriate for manufacturers of components that include bracing not designed for primary loads (diaphragms, cross frames and lateral bracing); camera, light, sign and signal support structures; bridge rail; stairs; walkways; grid decks; drains; scuppers; expansion joints; bearings; ballast plates; and mechanical movable bridge equipment.


Sophisticated Paint Endorsement
The Sophisticated Paint Endorsement is a quality certification program designed to evaluate the qualifications of structural steel fabricators and manufacturers of bridge and highway metal components who apply sophisticated or industrial protective coatings, such as zincs, expoxies, urethanes, or multi-coat systems in their paint shops following fabrication. The Sophisticated Paint Endorsement meets quality program criteria requirements of SSPC-QP 3, "Standard Procedure for Evaluating the Qualifications of Shop Application Firms." Also, The Sophisticated Paint Endorsement is based on industry standards and manufacturers' storage, surface preperation, application and curing requirements. There are currently three Paint Endorsements available:

                    • P1-Sophisticated Paint Endorsement-Enclosed
                    • P2-Sophisticated Paint Endorsement-Covered
                    • P3-Sophisticated Paint Endorsement-Outside


Certified Steel Erector (CSE)
Erection contractors providing services necessary for erection of structures such as schools, shopping centers, light manufacturing plants, warehouses, low-rise beam and column structures, simple non-continuous bridges, and steel-framed buildings.

A Certified Steel Erector must have the following items:

                    • Erection plan
                    • Formal safety plan
                    • Program to promote project planning
                    • Formal program to monitor compliance with required welding and bolting procedures
                    • Written substance abuse plan and policy

Advanced Certified Steel Erector (ACSE)
Erection contractors providing services necessary for erection of structures such as large public and institutional buildings, heavy manufacturing plants, bunkers, bins, major bridges, continuous girder bridges, railroad bridges, powerhouses, major industrial facilities, locks and dams, high-rise structures, arenas, and repair and rehabilitation of existing steel structures. The organization shall understand the procedures involved and have ready access to the requisite talent, resources, and experience necessary to erect complex steel structures

An Advanced Certified Steel Erector must have the following items listed below as well as meet the requirements for Certified Steel Erector:

              • Implementation of the quality and safety systems defined in the Certified Advanced Steel Erector checklist
              • Experience in staged construction for maintaining traffic
              • Experience in composite and concrete core construction
              • Experience in close tolerance erection (as in architecturally exposed structural steel)
              • Experience in use of gantry and other specialized crane systems
              • Experience in retrofit and maintenance
              • Experience with complex projects such as working over water and railroad tracks
              • Experience with large-scale erection projects
              • Experience and equipment for rivet removal
              • Written procedure for jacking and use of falsework
