Tyler Building Systems is AC472 accredited by the International Accreditation Service (IAS).

What does “AC472 Accredited” mean?
AC472 refers to the “Inspection Programs for Manufacturers of Metal Building Systems (AC472).” It is a comprehensive, third-party accreditation program for the inspection of metal building manufacturers and is based on the requirements of Chapter 17 of the International Building Code®. AC472 provides code officials with a means to approve the inspection programs of manufacturers involved in the fabrication of metal building systems

AC472 was developed by the International Accreditation Service (IAS), a wholly-owned subsidiary of the International Code Council (ICC), in collaboration with the Metal Building Manufacturers Association (MBMA). IAS accredits testing and calibration laboratories, inspection agencies, building departments, fabricator inspection programs and International Building Code® special inspection agencies. A recognized accreditation body since 1975, IAS is a nonprofit, public benefit corporation. IAS is one of the leading accreditation bodies in the United States and a signatory to several international mutual recognition arrangements (MRAs).

What does the AC472 require of a metal building manufacturer?
The inspection program outlined in AC472 addresses quality management system elements such as personnel requirements, product traceability, process control, and various administrative and technical requirements. The criteria, in fact, covers all system elements that are essential if code officials, building owners, specifiers and contractors are to have full confidence in, and approve, IAS-accredited fabricators of metal buildings. Of particular significance to building owners, specifiers and code officials is the fact that AC472 meets the requirements of Chapter 17 of the International Building Code. In addition, accredited firms must have AWS Certified Welding Inspector (CWI) in accordance with the provisions of AWS QC1, Standard Guide for Qualification and Certification of Welding Inspectors.

As a result of all these measures, architects, design professionals, building code officials and the insurance industry can be assured that accredited metal building systems manufacturers are capable of meeting the industry s highest standards for product and design integrity.

Why should I care if my metal building supplier is AC472 accredited?
An AC472 accredited company has been placed through a rigorous examination to confirm that it has the personnel, organization, experience, procedures, knowledge, equipment, capability and commitment to produce work of the required quality. Accredited companies will have quality systems in place with defined positions and responsibilities.

Both the internal and external reviews help companies improve production practices and product quality at a facility. In addition to IAS personnel, the AC472 Accreditation Program uses third party Accredited Inspection Agency that have people experienced in engineering, fabrication, welding and auditing which brings a hands-on approach to the accreditation procedure. By reviewing records, evaluating engineering procedures , interviewing personnel and observing welding practices and equipment in the shop, IAS and its Accredited Inspection Agency confirm that a quality assurance program is in place that meets AC472 Criteria. After a company is AC472 Accredited, two annual review processes each year ensure confirmation of an ongoing commitment to quality systems. These semi-annual reviews also offer companies the opportunity for improvement and help communicate the latest quality issues.
