Lessons Learned: Trades that Need to Include an AVB Discussion in their Specification & Preinstallation Meetings

When designing a building envelope wall system, specifying, detailing and having a pre-installation discussion about the backup substrate and façade elements, considering the water, air, vapor and insulation systems detailing, is critical. This involves careful coordination with all façade trade elements, consideration of construction and installation tolerances, addressing the installation requirements for the substrate wall, water and air resistive barriers, insulation and façade support system, and learning lessons from each installation. Each component must be thoroughly understood and specified within their respective specification sections to ensure comprehensive detailing. By understanding the necessary connections, material compatibility, tested systems and limitations of construction materials, you can develop pre-installation conversation points within each building envelope and substrate meetings to proactively develop an advanced conversation about detailing, grasping the construction requirements for each component and incorporating lessons learned will enhance future detailing and specifications will significantly improve the chances of project success.

Learning Objectives:

• Identify early structural design considerations needed to maintain air, vapor, water, insulation and rainscreen systems in bid documents.
• Incorporate construction tolerances when detailing substrate walls and control layers for various façade systems.
• Recognize common substrate and façade wall systems and the detailing needed to coordinate drawings and specifications.
• Apply lessons learned on continuity, fastening, membranes and system tolerances to improve coordination and guide pre-installation meetings.
