The Key to a Successful Project: Preconstruction Building Enclosure Coordination Meetings

Track 2: Building Enclosures

Wednesday, April 8, 9:45am – 10:45am

An air barrier is a system of materials designed to control the flow of air between conditioned and non-conditioned spaces. While air barriers have been incorporated into wall assemblies for decades, It is important to note that the building envelope includes all sides of the building, including the exterior walls, the lowest-level floor, and the roof or ceiling assembly. Once additional sides of a building are included the detail becomes a challenge because not only is there a transition between air barrier materials, but there are also different trades involved, and sequencing becomes important. This presentation will review the importance of a preconstruction coordination meeting in identifying material transition ownership and installation sequence. The presentation will review how the buy-out process of the sub-contractors can impact the air barrier detailing. The speaker will review case studies and page by page turn that can reduce the “by other” syndrome and identify potential gaps between trades that will require further coordination.

Learning Objectives:

  1. The speaker will review the requirements and process of a coordination meeting.
  2. Identify how installation sequence impacts detailing and installation of building air barrier components.
  3. Learn about unique solutions to improve the construction of a continuous air barrier.
  4. Review air barrier transitions and the responsibility of multiple sub-trades and their impact on air barrier detailing.
