2022 Martin S. Kapp Lecture and “Meet & Greet” Dinner
ASCE Metropolitan Section presents: The 47th Martin S. Kapp Lecture and the 17th Annual “Meet & Greet” Dinner
Evolution of Geotechnical Design as Illustrated by the Building and Re-Building of the World Trade Center
Join Ray Sandiford, HNTB’s National Practice Lead for Geotechnical Engineering, to learn about the evolution of geotechnical design with specific examples from the World Trade Center.
The original WTC was designed in the mid-1960s, where Marty Kapp led a team of designers that used what was then state-of-the-art geotechnical engineering to create truly monumental structures. Although not the first use of the slurry wall construction method, its application at the WTC was monumental in scale and, at the time, a considerable risk. The designers used the latest in earth pressure theory to model the staged construction of deep, multi-level walls and used instrumentation to validate their models. The foundations for the slender twin towers also presented other challenges. Although all of the original analyses on punch cards were lost during the tragic event, the test and instrumentation data survived and provided valuable information for the reconstruction after 9/11. Ray will discuss how the current design leveraged the original design work and some of the lesser-known geotechnical challenges of the WTC reconstruction.
