“By Others” – The Elusive Sub-contractor Responsible for Transitions

BEC
October 09, 2020
12:00 pm - 1:30 pm
Location
Virtual Meeting via Webinar
Posted by Jeff Diqui

AIA CREDIT: Yes

ABSTRACT:

This presentation will provide an in-depth look at the transitions between environmental separators for the roof, wall, and fenestration assemblies related to water control, air leakage control, thermal performance and vapor control.  Critical details that can contribute to building performance related issues will be the focus of this discussion.  Several variations of roof to wall connections and wall to window connections specific to curtain wall systems will be reviewed. A step by step evaluation of critical details in regards to sequence of construction, transition material options, and the various connections methodologies to produce airtight/watertight and thermally protected details will be presented.  Construction photos and job conditions will bring the realities of the construction process to illustrate typical issues found and how they can be potentially be addressed.

LEARNING OBJECTIVES:

  1. Articulate how exterior enclosure transitions can impact building enclosure performance through example projects in regards to energy loss, building performance and the sustainability of the system.
  2. Correctly identify and prioritize critical details during the construction document phase to ensure an integrated approach is taken to water, air, heat, and vapor control.
  3. Assess each detail in regards to impacts of the 4 control layers and understand the various options for designing details for a variety of roof, wall, and window assemblies.
  4. Through the use of case studies and photos, plan out the proper sequence of construction and identify quality control methods in construction document review to provide corrective action.
