In Situ: The Modern Concrete Skyscraper
Skyscraper histories often treat the development and evolution of the skeletal steel frame as the very definition of the modern high-rise. Yet the story of steel leaves out what has been, arguably, the most important material to tall building construction over the past 100 years: reinforced concrete.
Concrete’s plasticity and its monolithic nature have allowed a wide variety of architectural forms and engineering approaches. From the pioneering Ingalls Building of 1905 in Cincinnati, through the 1960s experiments with tube construction in Chicago, to the "buttressed core" of the Burj Khalifa, the world's tallest building, concrete’s monolithic behavior, adaptability to a wide range of forms, and low
material cost have pushed the development and application ofconcrete toward its current global status as the material of choice for high-rise structures.
In preparation for the Fall 2023 exhibition In Situ: The Modern Concrete Skyscraper, the Museum is launching an evolving lecture series that will examine key experiments in concrete construction. The series examines a range of paradigmatic concrete skyscrapers throughout history, showing how the material’s unique structural properties and its versatile nature have inspired designers to create radically new forms and to push skyscraper engineering to its current limits.
Intended to spark a renaissance in downtown living, Bertrand Goldberg’s design relied on concrete’s formal agility to achieve a pioneering example of mixed-use urbanism, combining commercial, residential, and retail functions within its cylindrical towers and expressive plaza buildings. Relying on techniques borrowed from the Midwest’s long tradition of slip-form grain elevator construction and on innovative formwork systems developed by the contractor, Marina City remains one of the city’s most notable and recognizable developments—and a foil to Chicago’s ubiquitous steel-framed boxes.
Our series begins with a talk by architect Geoffrey Goldberg on the remarkable pair of 61-story cylindrical towers completed in 1964. Goldberg will describe how that city’s famous twin apartment towers used concrete toward important social and political ends in the early 1960s. The program will be introduced by Thomas Leslie, guest-curator for the exhibition In Situ.
Chicago’s extensive history of steel skyscrapers conceals the city’s important innovations in concrete. Since the early 1900s, architects, engineers, and builders in Chicago explored concrete’s formal and structural versatility, leading to important developments in formwork, structural concepts, and material science. Bill Baker, emeritus partner at SOM, will discuss this history and the importance of one building in particular: Chestnut-DeWitt, an apartment tower from the early 1960s designed by Bruce Graham and Fazlur Khan, of SOM, that pioneered the tube structure in concrete, an idea that would later form the basis for steel towers such as Sears and John Hancock. He will be joined in conversation by Thomas Leslie, Professor of Architecture at the University of Illinois Urbana-Champaign and author of Chicago Skyscrapers, 1934-1986.
Completed in 1960, Milan’s Pirelli Tower, or Grattacielo Pirelli, was the tallest building in the Northern Italian city. Designed by the leading Italian modernist Giò Ponti in collaboration with the renowned structural engineer Pier Luigi Nervi, the Pirellone, or “Big Pirelli," was constructed of concrete, like nearly all Italian and European high-rises. Join us on July 26 at 4pm ET (2 hours earlier than our usual start time) for a talk by Marko Pogacnik, a professor at the University Iuav Venezia, on the Grattacielo Pirelli and the postwar Italian skyscraper. As Pogacnik will illustrate, the war-ravaged city of Milan in the 1950s witnessed a strong desire for urban renewal, manifested in the construction of a series of tall buildings: Torre Breda 1950-55; Torre Velasca 1955-58; and Torre Galfa 1956-59. At 32 stories and 127m/417 ft., the outstanding building of this postwar boom in both height and artistic achievement was the Pirelli Tower. In it, architect Giò Ponti and structural engineer Pier Luigi Nervi, with Arturo Danusso, sought to establish a distinctive Made-in-Italy skyscraper that abandoned the standard American approach of the steel frame in favor of the use of reinforced concrete in the form of heavy partitions and expressive structure.
Professor Pogacnik will illustrate the modernist principles propounded by Giò Ponti and the inspired collaboration with Nervi and Danusso. After his presentation, he will converse with Tom Leslie, author of Beauty's Rigor: Patterns of Production in the Work of Pier Luigi Nervi (2017).
Designed in 1960 and completed in 1965, the CBS corporate headquarters, known as Black Rock, was New York's first concrete office tower. Architect Eero Saarinen envisioned a sober granite-clad monolith – rising from a sunken plaza on a full Midtown block on Sixth Ave. from 52nd to 53rd streets – a form that contradicted the modernist paradigm of the gleaming glass boxes of Park Avenue. The engineer Paul Weidlinger likewise defied the standard approach of steel-frame construction and proposed a structure of reinforced-concrete columns, based on his experience in Washington DC and his background in France and Bolivia.
Matthys Levy, who as a young engineer worked with Weidlinger on Black Rock and later became a founder of WAI, Consulting Engineers, will discuss their work on this unique skyscraper and compare it to contemporary towers in New York and other US cities.
Completed in 1967, six years before Jørn Utzon’s Sydney Opera House, Australia Square was the first truly modern skyscraper on the continent and, arguably, the world’s tallest lightweight concrete building. The 50-story cylindrical tower once stood alone as the focal point of a full city-block development in Central Sydney and with a popular plaza that made the complex the first successful large-scale commercial project in Australia. Vienna-born Emigré architect Harry Seidler (1923-2006) brought his Harvard GSD and Black Mountain College training and experience in the offices of Marcel Breuer and Oscar Niemeier to his adoptive Australia where he became the country's leading postwar modernist. Australia Square also began Seidler’s creative collaboration with Italian structural engineer Pier Luigi Nervi, with whom he worked on a number of large projects.
Vladimir Belogolovsky, author of Harry Seidler: LifeWork (Rizzoli, 2014) and curator of Harry Seidler: Painting Toward Architecture will discuss Australia Square’s design and construction principles and inherent circular geometry, placing Seidler's first iconic tower in the context of other key projects with similar concrete technology and geometric principles. After his talk, he will be joinmed in conversation by Tom Leslie, author of Beauty's Rigor: Patterns of Production in the Work of Pier Luigi Nervi (2017).
The most famous residential structures of postwar Chicago are still Mies van der Rohe’s 860-880 Lake Shore Drive with the modernist expression of their steel skeleton. But Mies also designed in concrete, as did many Chicago architects and builders throughout the 20th century. Chicago developed home-grown expertise in flat slab, “rib-cage,” and tube construction that produced remarkably innovative residential towers across the city. While a few of the postwar icons—Marina City and Lake Point Tower, for instance—are well studied, others such as Lawless Gardens, 320 Oakdale, and Quadrangle House deserve greater attention for the impact they had on the city’s building culture.
In this webinar, Thomas Leslie will discuss his new book, Chicago Skyscrapers, 1934-1986: How Technology, Politics, Finance, and Race Reshaped the City, an expansive architectural history that tackles the history of a half century of Chicago's built environment.
Continuing our series on The Modern Concrete Skyscraper and the role of concrete as the material of choice in high-rise residential construction, David West of the architectural firm Hill West will return the focus to New York City. Tom Leslie's earlier talk on apartments in Chicago from the 1960s to 1980s illustrated the experiments in both engineering approaches and formal expression. Over 35 years of practice, David West has spearheaded the design of over 150 multifamily projects. His talk will cover the history of residential high-rise design from the postwar years, explaining developments such as the significance of reinforced flat-plate construction and the impact of zoning and regulatory environments on housing production. The catalog of Hill West's work including recent projects such as Bankside, 11 Hoyt, 363-365 Bond Street, and 130 William illustrates the range of development solutions in the city.
