Expansion Joint Design Best Practices

BEC
May 14, 2021
12:00 pm - 1:30 pm
Location
Virtual Meeting via Webinar
Posted by Jeff Diqui

AIA CREDIT: Yes

ABSTRACT:

Often architectural drawings include a manufactured expansion joint system sized to accommodate the anticipated structural movement of the joint with limited consideration to the adjacent building enclosure systems. Structural engineers view expansion joint systems as a separator between two buildings that move differentially, while building enclosure engineers consider expansion joints as a connector between roof, waterproofing, air/water/vapor control layer, and fire barrier systems. This presentation will address how to detail, develop, and construct expansion joint systems to maintain enclosure air/water/vapor and thermal barrier continuity and prevent leakage.  The presented approach is based on the presenters’ combined experience in managing projects that include expansion joints from design to final completion and in investigating failed expansion joint systems.

LEARNING OBJECTIVES:

  • Understand how expansion joints fail from a building enclosure perspective.
  • Overview of the various expansion joint systems that are available and the appropriate applications for each system.
  • Learn what details, systems, and configurations should be included in a construction drawing set to “own” a continuous expansion joint in the design.
  • Understand what specification requirements to include in the contract documents to set up the expansion joint system for success during construction.
