AC478 Accreditation: A Strict Process for Quality Assurance in PEMB Construction



In construction, precision, safety, and quality stand as priority number one.

Whether it’s an industrial facility, a commercial space, or an agricultural structure, selecting the ideal team to construct and raise your metal building influences your project’s success. This is where you’ll notice the significance of AC478 Accreditation.

Let’s explore the strict process involved in achieving AC478 Accreditation and the advantages of selecting an AC478-accredited team for the job.

The Path to AC478 Accreditation

The Inspection Practices of Metal Building Assemblers’ accreditation committee outlines, in detail, the stringent requirements for metal building assemblers.

While there are several requirements, we picked out some of the most important ones to show you:

Preparation and Documentation Submission

Like any good accreditation program, it starts with paperwork—lots of it.

Metal building assemblers must prepare and submit detailed documentation about their safety and management systems to the International Accreditation Service, Inc. (IAS) for initial review.

This documentation also outlines quality assurance activities to ensure the assembly meets specified requirements. The submitted documentation should include a cross-reference matrix signed by the quality manager.

Safety and Training Programs

Assemblers must establish and maintain documented training and safety programs. The safety program must describe the procedures and activities for ensuring that all employees, subcontractors, and processes comply with minimum OSHA standards and/or applicable regulatory requirements.

They should also have a detailed training program that includes mandatory OSHA 10 training and completion of the MBI Quality and Craftsmanship Training Series. The guidelines state that assemblers must review the documentation at least once a year.

Key Personnel Identification

It is crucial to identify and assign individuals within various roles to maintain a functioning organization. This could include a quality manager, a safety manager, and a training manager. These personnel play an important role in ensuring the management system’s effectiveness while also overseeing safety measures and training programs.

Insurance Coverage

Accredited assemblers must maintain specific insurance coverage, including:

  • Workmen’s Compensation
  • Comprehensive General Liability
  • Comprehensive Automobile Liability
  • Umbrella Excess Comprehensive General and Comprehensive Automobile coverage

Advantages of Choosing an AC478 Accredited Team

A metal assembler goes through stringent tests before achieving AC478 accreditation. This creates a reliable partner for commercial PEMB construction.

Some of the main benefits of choosing an accredited assembler include:

  • Simplified Process: By choosing an AC478-accredited team, clients don’t need to worry about explaining each step. The assembler will have an established and seamless workflow through their safety and management systems.
  • Prioritize Safety: AC478 teams prioritize safety, ensuring a secure project site.
  • Code Compliance: Teams accredited with AC478 are aware of and obedient to construction codes, which helps avoid problems and delays.
  • Skilled Workforce: AC478 teams invest in training for an efficient and high-quality project. Their workforce is equipped with the latest industry knowledge and is familiar with the best practices.
