SEAOI, with IABSE and SEAoNY Programs Committee, Presents:

Three Supertall Slender Towers in Midtown Manhattan

Join us for a unique presentation hosted simultaneously both in SOM's NY and Chicago offices, reflecting the collaborative nature of the structural engineering efforts for these projects.

One Manhattan West, Two Manhattan West and 35 Hudson Yards are three slender supertall towers recently designed and engineered by the authors' company that rise above the underground train tracks approaching New York City’s Penn Station on the west side of the island of Manhattan. Although the slender towers are neighbors and have similar heights and proportions, each tower resolves the constraints of the underlying tracks with unique structural approaches. The disparate below-ground conditions result in three distinct structural solutions that are all governed by the effects of the wind. All three towers were subjected to extensive wind tunnel testing programs in order to optimize their dynamic behavior. The paper in the IABSE Journal Structural Engineering International (SEI) describing this project won the 2023 IABSE Outstanding Paper Award (OPA).

About the Speakers

William Baker is a structural engineering consulting partner at Skidmore, Owings & Merrill, where he led the structural engineering practice for over 20 years. Since joining SOM in 1981, he has endeavored to extend the profession of structural engineering through design, research, teaching, and professional activities. He is a Member of the U.S. National Academy of Engineering and an International Fellow of the Royal Academy of Engineering U.K. He’s best known for developing the “buttressed core” structural system for the Burj Khalifa, the world’s tallest manmade structure. He is actively involved with numerous professional organizations and institutions of higher learning and is an Honorary Professor at the University of Cambridge.

Brad Young is an Associate Principal in the Structures group in the Chicago office of Skidmore, Owings & Merrill. Brad has worked on a number of tall and supertall building projects around the world including the Middle East, China, and the US. Brad is a Chair of the ASCE7 Wind Loads Subcommittee and runs SOM’s own experimental wind tunnel laboratory

Preetam Biswas is Principal of Structural Engineering at the SOM New York office with a wide range of international project experience. He has significant experience designing innovative structural systems for super-tall towers, long-span structures and specialty structures such as cladding systems and cable wall systems.

Georgi Petrov is practicing architect and structural engineer and space architect. He is a Senior Associate Principal in the structures group at the New York office of Skidmore, Owings & Merrill, where he works on highrises and long span structures around the world. He is a licensed Architect and Professional Engineer. He is an adjunct professor at NYU where he teaches Design of Tall Buildings.
