Metal Building System Assemblers - Add Accountability and Value!

The AC478 Accreditation program is the most comprehensive quality assurance accreditation of its kind for metal building assembly. It is administered by the International Accreditation Service, a member of the International Code Council Family of Solutions which develops the IBC codes.

It verifies a contractor and erector's compliance in the following areas:

  • Documented safety and training program
  • Documented management system
  • Job-Site Specific Assembly Plans

An onsite jobsite assessment verifies that a company is performing in line with their plans. This, along with annual Internal Audits and Management Reviews, assures owners that the erector they have chosen follows a comprehensive quality driven metal building assembly program. 

The MBCEA encourages all metal building contractors and erectors to pursue this important mark of quality. We recommend building owners, developers, and architects require AC478 accreditation in their specifications and that building officials look for it before issuing permits. An increasing number of architects are specifying the use of accredited companies.
