Consulting Partner, SOM
Brian Lee, now a consulting partner, practiced in the SOM’s San Francisco office for 28 years before joining the Chicago office in 2007. Lee has designed landmark structures around the globe, including projects in East and Southeast Asia, Europe, and the Middle East. Among his award-winning high-rise projects are the China World Trade Center, the centerpiece of Beijing’s Central Business District, and Poly International Plaza in Guangzhou, China, and the 530-meter supertall, Tianjin Chow Tai Fook Binhai Centre.
Tianjin CTF Finance Centre dominates the Tianjin Economic-Technological Development Area (TEDA), located just outside Tianjin, the coastal city south of Beijing that is China’s fifth largest metropolis. The sleek tower, unique among uses undulating curves that subtly express three programmatic elements: offices on the broad lower floors, serviced apartments in the shaft above, and a luxury hotel in the tapering top floors. The curtain wall of gently curving glass conceals the innovative structural system of eight sloping columns that increase the structure’s stiffness in response to seismic concerns. Multistory wind vents combined with the tower’s aerodynamic shape reduce vortex shedding, which in turn dramatically minimizes wind forces.
Lee’s design approach is focused on achieving full integration of the natural and built environment through the most innovative design forms, materials, and construction technologies. Brian received his BA in Architecture from the University of California, Berkeley in 1976 and his Master of Architecture from Harvard University Graduate School of Design in 1978.
With three decades experience at the firm, Robert Whitlock is one of KPF’s foremost designers of high-rise towers, mixed-use developments, and large-scale master plans. He is the design principal for three supertalls in our exhibition: Suzhou International Finance Square, a 450-meter signature tower of the ancient Chinese city; Chongqing International Trade and Commerce Center, a 475-meter tower that anchors a development for Shui On Land in the megacity of southwestern China; and CITIC Tower, at 528 meters the tallest building in Beijing. Also known as China Zun after the flaring form of a Bronze-Age ritual vessel, the 109-story tower is the headquarters of CITIC Group, a state-owned investment company.
Whitlock focuses his high-rise and mixed-use master plan designs on density, public space, programmatic integration, and the influences of these elements on the quality and sustainability of the “multi-layered city.” His projects for the Shenzhen Chegongmiao District and Greenland Bund Centre in Shanghai explore new ways of creating active urban spaces. In Hong Kong, he led the design of Hysan Place, the city’s first LEED Platinum building that provides elevated public gardens and draws prevailing breezes though the site. In Singapore, his design for 18 Robinson integrates green space vertically throughout the structure.

Consulting Partner, SOM
Bill Baker is a structural engineering partner at SOM where he has led the firm’s practice for over 20 years. Since joining SOM in 1981, he has dedicated himself to extending the profession of structural engineering through design, research, teaching, and professional activities.
Baker is best known for the development of the “buttressed core” structural system for the Burj Khalifa in Dubai, the world’s tallest manmade structure. Completed in 2010, the 828-meter Burj surpassed the then-tallest Taipei 101 by more than 300 meters. This unprecedented vertical leap was accomplished by iterative responses to wind-tunnel testing and other creative solutions to constructability. In his talk, Bill will discuss both the precedents that allowed their team to invent a new structural approach, as well as the legacy of “Lessons Learned” a decade after the completion of the skyscraper that still remains the world’s tallest manmade structure.
Active with numerous professional organizations and institutions of higher learning, Bill Baker has received many honors, including three honorary doctorates; the Gold Medal from the Institution of Structural Engineers (IStructE), the American Society of Civil Engineers (ASCE) Outstanding Projects and Leaders Lifetime Award for Design; the Gustav Magnel Gold Medal from the University of Ghent; the Fazlur Rahman Khan Medal from the Council on Tall Buildings and Urban Habitat; and the Fritz Leonhardt Preis (Germany).

Principal, Thornton Tomasetti
Structural engineer Robert Sinn is a Principal in the Chicago office of Thornton Tomasetti. Before joining TT in 2007, Bob spent more than two decades at SOM, where he was responsible for such award-winning projects as the Guggenheim Museum Bilbao in Spain, and Trump International Hotel and Tower in Chicago, which when completed was the tallest all-concrete building in North America. Recent project credits include the 245-meter Federation of Korean Industries headquarters (2014) in Seoul, South Korea, the Al Wasl Plaza for Expo 2020 in Dubai, UAE, topped by a translucent dome that spans 130 meters.
Sinn led the structural design team for Saudi Arabia’s Jeddah Tower, which if completed as planned will be the first man-made structure to reach a height of one kilometer. As he has explained in lectures on the megatower, the three-legged buttressed core is developed as a pure bearing wall system where all gravity loads are carried entirely by reinforced concrete walls. According to Bob, the structure of the first structure deigned to exceed 3,200 feet is “simplicity itself.”
Educated in Civil Engineering at Northwestern University and Massachusetts Institute of Technology, Bob is a fellow of the American Concrete Institute, the American Society of Civil Engineers and the International Association of Bridge and Structural Engineering.

In her new book, Prof. Elizabeth Macaulay-Lewis applies an archeological lens to the study of the New York buildings. Antiquity in Gotham explores how the language of ancient architecture communicated the political ideals of the young Republic through the adaptation of Greek and Roman architecture; how Egyptian temples conveyed the city’s new technological achievements; and how the ancient Near East served many artistic masters, decorating the interiors of glitzy Gilded Age restaurants and the tops of skyscrapers. Rather than emphasizing a battle of styles, the Neo-Antique framework considers the similarities and differences—intellectually, conceptually, and chronologically—amongst the reception of these architectural traditions.
Elizabeth Macaulay-Lewis is Associate Professor of Liberal Studies and Middle Eastern Studies, and the Executive Officer of the M.A Program in Liberal Studies at the Graduate Center, the City University of New York. She is the editor or author of six books, including Classical New York: Discovering Greece and Rome in Gotham and Housing the New Romans: Architectural Reception and Classical Style in the Modern World.
