A Case Study on Window Wall Water Leakage Evaluation & Subsequent Repairs

BEC
March 11, 2022
12:00 pm - 1:30 pm
Location
Virtual Meeting via Zoom
Posted by Jeff Diqui

AIA CREDIT: Yes

DESCRIPTION:

This presentation is a case study of a high-rise residential building focusing on a detailed evaluation of a window wall system where water leakage issues were becoming increasingly more prevalent.  The presentation will dive into the mechanisms that contributed to the leaks and the repair alternatives that were derived from the investigation.  The building’s facade includes several curved walls, recessed balconies, and cantilevered balconies, and consists of a floor-to-ceiling aluminum-framed glazed strip window wall system with aluminum spandrel panels along floor lines.  

LEARNING OBJECTIVES:

  • Understand window wall systems, including their components and configuration; 
  • Discuss why a water leakage evaluation and subsequent repairs were needed for the case study building, including a brief history of the building itself;  
  • Examine the mechanisms and ways of identifying water leakage;  
  • Understand the benefit of presenting multiple repair approaches with advantages and disadvantages so a building owner can make educated decisions on maintenance of their building.
