About This Program

There seems to be a lack of understanding of what quality assurance entails versus quality control, the fundamental differences between the two, and what each function brings to the table. This is not unique to the ABAA air barrier quality assurance program or the construction industry in general. These terms are used interchangeably and misunderstood in all industries.  

In this presentation, a discussion of how to implement quality assurance and quality control will be explored specific to the building enclosure, and the steps you can take to ensure a high-performance building.

Session Takeaways

  • Explore how quality management systems can be applied to the construction process, and how quality assurance differentiates with quality control
  • Assess potential impacts to cost, scheduling, building performance, and durability by poor installation of air barriers
  • Describe language required in a specification that provides key criteria in regards to implementing an air barrier site quality assurance program
  • Define key components of an air barrier site quality assurance program, and assess the importance and relationship of each component

  • Laverne Dalgleish, CABS, Executive Director Air Barrier Association of America

    Mr. Laverne Dalgleish was requested in 2000 to organize a trade association that would focus on the air barriers that were going to become a requirement in the Commonwealth of Massachusetts building code on July 1, 2001, specifically to deal with training the installers.
    Laverne had managed trade associations and had developed a Site Quality Assurance Program based on his work in developing standards at the International Organization for Standardization (ISO).
    Over the years, Laverne has spearheaded the development of material specifications, test methods, training courses, installer certification and research projects, all to bring organization and technical documents that were used to grow the air barrier industry
    Over the years, Laverne has become a frequent presenter across North America and Internationally on a variety of topics as they relate to building envelopes, energy efficiency, green building practices, and standards and quality of construction.
