Construction Referees: Evaluation Processes for Alternative Building Products By Jeff Ellis, Director of Codes and Compliance
T
here are products used in many buildings that are not referenced by the codes or standards. These products can affect structural strength, stability, fire resistance and other building performance attributes, which can impact public safety, health and general welfare. The International Building Code Section 104.11 (Alternative materials, design, and methods of construction and equipment) provides guidance on the approval process for the use of alternative products in the built environment. The code section identifies the building official as the evaluator and decision-maker. This is similar to a referee determining a player’s compliance with the rules. The code section 104.11 indicates that the alternative material, design, and methods of construction shall be approved where the alternative complies with the intent of the code. The supporting data shall consist of valid research reports, and, in the absence of recognized standards, the building official shall approve the testing procedures. This is somewhat similar to asking the referee to write the rules during the game and expecting all referees to independently write and interpret the rules similarly for every game. In the absence of publicly developed and majority-approved provisions, the building official is tasked with ensuring that the data provided is appropriate and adequately proves the alternative product meets code intent to protect public safety, no matter the product type or complexity. This is compared to the robust code development process in which committees with balanced representation publicly develop and deliberate on provisions in order to protect public safety. The question arises whether the 104.11 requirement implies that a process should be used in the development of test and evaluation requirements for alternative products that is similar to the development of code and standard provisions: public debate, resolution of negative opinions and a majority approval of the requirements. Requiring a similar code development process for alternative products makes sense. Can the public and manufacturers afford the time and expense of a code-like evaluation process for alternative materials? Is the alternative product to be approved next time the same and are the building code requirements the same as they were the last time? Can the public and manufacturers expect the same rules from different referees every time? Some believe that building officials and registered design professionals have plenty of time to consider the complexities of alternative products and design methods. However, we know that building officials and design professionals are already substantially tasked with the building systems that rely on code-recognized materials and methods. Is there a solution that balances providing innovative and cost-effective alternative building product solutions to the building industry in a timely manner with providing a thorough product assessment that ensures consistency and public safety? Accredited building product certification companies, or evaluation service companies, that use publicly developed and majority-approved acceptance or evaluation criteria and publish an evaluation report with the product’s description, design and installation requirements and limitations provide such a solution. These evaluation service companies are a third-party resource that assist building officials in determining whether an alternative product meets code intent and should be approved for use in their jurisdiction. One of a number of evaluation service companies is the ICC Evaluation Service. ICC-ES has been performing structural product evaluations for many years and is ANSI accredited to ISO/IEC 17065 (Conformity Assessment – Requirements for bodies certifying products, processes, and services) to provide building-code product certifications (ICC-ES). However, accreditation by itself mainly verifies that a certain process is implemented to ensure consistency and confidentiality. ICC-ES is one evaluation service that also has a public acceptance criteria process. This process includes an evaluation committee made up of building enforcement officials. These officials on the committee evaluate the proposed criteria, listen to expert and industry input, and only approve the criteria by a majority vote if products evaluated to those criteria will meet code intent. This is similar to the codes and standards development process — a transparent public process and a majority approval of requirements for many project Continued next page types and conditions and not just an opinion of one or a couple of individuals.
