| Gary S. Wentzel. P.E. (AE ’95) and Matthew
C. Farmer, P.E. of Wiss, Janney, Elstner Associates, Inc.(WJE), Fairfax,
Virginia, provided a lecture on “Thin Stone Cladding Failures,” on September
27, 2000, as part of the AE 537- Building Failures and Forensic Techniques
Guest Lecture Series. The featured project was the stone façade
replacement of a ten-story office building in Arlington, Virginia (cover
photo). The scope of the project involved the removal of granite
panels due to the failure of existing anchors, installation of an innovative
aluminum extrusion channel support system, and re-setting of the original
granite cladding panels from the building exterior (shown below).
The project was completed while maintaining 100% building occupancy.
The
Building Failures and Forensic Techniques course was developed by Prof.
Kevin Parfitt as a means of learning about building and building assembly
performance by examining a variety of failure information collections.
A popular feature of the course is a series of guest lectures by professionals
well known for their work in building performance.
