QA includes those tasks designated “special inspection” by the applicable building code. Quality Assurance (QA): Monitoring and inspection tasks performed by a registered design professional, firm or approved agency other than the component manufacturer or installer to ensure that the material provided and work performed by the component manufacturer and installer meet the requirements of the approved construction documents and referenced standards. Quality Control (QC): Controls and inspections implemented by the component manufacturer or installer to confirm that the material provided and work performed meet the requirements of the approved construction documents and referenced standards Similar to the AISC and SDI standards, the AISI S240 Chapter D provisions define key terms, establish responsibilities, and set requirements for the following: QC programs, QC and QA documents, inspection personnel, inspection tasks, and nonconforming material and workmanship. While the proposal was not approved for the 2015 edition of the IBC, many of the requirements seemed relevant given today’s larger cold-formed steel framed buildings.

The AISI task group also considered recommendations from a recent ICC code change proposal for the International Building Code (IBC) authored by the National Council of Structural Engineers Associations (NCSEA) – ICC S145-12. Rather than reinvent the wheel, the AISI provisions were patterned after similar requirements adopted by the American Institute for Steel Construction in the Specification for Structural Steel Buildings (AISC 360-10 Chapter N) and the Steel Deck Institute in the Standard for Quality Control and Quality Assurance for Installation of Steel Deck (SDI QA/QC-2011). Shortly afterwards, an AISI task group was formed and efforts to write the provisions began in earnest. In 2013, the AISI Standards Council assigned the development of the new QC and QA provisions for cold-formed steel structural framing to the Standard Practices Subcommittee of the Committee on Framing Standards (COFS). These new requirements are contained within AISI S240, Chapter D.
With the ever increasing size and height of cold-formed steel light frame buildings along with the consolidation of the AISI standards into the new AISI S240, the AISI Standards Council seized the opportunity to institute minimum QC and QA requirements. This article explores the new standard, with special focus on these new QC and QA provisions. In fact, one aspect is the brand-new chapter addressing the topic of quality control (QC) and quality assurance (QA).
Released at the end of 2015, AISI S240, North American Standard for Cold-Formed Steel Structural Framing, represents more than the sum of the individual parts. Over the past several years, the AISI Committee on Framing Standards (COFS), with oversight from the AISI Standards Council, has worked hard to develop a “whole” document to cover the structural design of cold-formed steel framing. Today, the landscape is much different for cold-formed steel light frame construction. Ten years ago, the AISI standards were compartmentalized into discrete packages on such topics as: general provisions, header design, truss design, structural wall stud design, floor and roof system design, and lateral force resisting system design. Commonly attributed to Aristotle, these words ring especially true when examining the recent evolution of the AISI standards. “The whole is greater than the sum of its parts” is an often-used phrase.
