Speaker: Stewart Jeske, M.S., P.E.
Presentation:
The majority construction projects include a requirement for delegated design of glazing systems in the specifications. These types of projects lack front-end design input from facade structural engineers and have limited manufacturer input leaving engineering design to the tail end of the construction. This delegated design process has significant problems leaving potential holes in the building envelope and significant risks of liability.
The glazing industry has rapidly evolved with advanced manufactured system but the design process has left gaps open. Discover the major issue overlooked associated with delegated design which accounts for an estimated 90% of all facade envelope damage and leakage 1-5 years after the construction is completed. The course wraps up with solutions to “Close the hole in the Envelope” and fix the delegated design process.
Learning Objectives:
- Identify common gaps in delegated design for glazing systems that lead to building envelope failures, particularly related to unaccounted structural movement and sealant joint design.
- Evaluate the limitations of standard glazing systems in accommodating vertical and lateral structural movement, and how these limitations contribute to moisture intrusion and performance issues.
- Analyze the roles and responsibilities of architects, structural engineers, façade engineers, and contractors in delegated design, and how misalignment between them creates risk.
- Apply best practices in specifications and project coordination to ensure structural movement is properly defined, communicated, and validated during delegated design of façade systems.
Learning Units will be provided: Yes (AIA CEU)
Speakers Bio:
With Professional Engineering (P.E.) licenses in 49 states, Stewart leads projects ranging from high-rise
façades to specialty glass structures. His portfolio includes structural glass engineering for the Liberty
Bell Pavilion, large-span glass walls, and complex designs for zoo and aquarium animal enclosures where safety, visibility, and durability are critical. JEI’s everyday expertise spans curtain walls, storefront systems, skylights, glass balconies, glass floors, and glass canopies—any project requiring unique knowledge of glass structure, connections, and performance.
Because U.S. universities teach engineering students to design in steel, wood, and concrete—but not glass or glazing—expertise in this field is rare. Stewart and the JEI Dream Team have built their knowledge through decades of hands-on project experience, becoming a go-to resource for architects, contractors, and manufacturers seeking to push the limits of what glass can do.
Stewart is the owner of four U.S. patents, including two related to façade system support, and is a sought-after continuing education presenter on glazing system design. For the past three years, he has also authored “Engineered Connections” in USGlass Magazine, sharing technical insights, best practices, and forward-looking perspectives with thousands of industry professionals.
Before founding JEI, Stewart served as a Senior Structural Engineer at Burns & McDonnell and as a Base Civil Engineer in the U.S. Air Force. He earned his B.S. in Architectural Engineering from Kansas State University and his M.S. in Civil Engineering from the University of Missouri–Kansas City.
From landmark cultural sites to complex specialty structures, Stewart’s career reflects a commitment to innovation, constructability, and delivering building envelopes that are as durable and safe as they are visually striking.
