Plunging into the archive: wandering off on tangents


In research there is no such thing as straightforward searching: the more time you spend in archives the more complex the picture gets. Let me use a recent experience of mine as an example. A few weeks ago I decided to take a train to Parma and visit the Pier Luigi Nervi Archive. It is housed at the CSAC, Centro Studi e Archivio della Comunicazione, in the Valserena Abbey

The Wizard of Concrete had been in the back of my mind for a long time and I was particularly interested in studying his first American project. John M. Kyle, Chief Engineer of the Port of New York Authority, commissioned the Washington Bridge Bus Terminal to Nervi in 1958. The building together with the Washington Bridge Apartments designed by Guenther & Brown and a parking structure were to rise on an existing metal structure conceived as part of the Washington Bridge Extension Complex to span the Trans-Manhattan Expressway, the only expressway planned by Robert Moses to be ever constructed.

Nervi’s drawings for the Bus Terminal are breathtaking. By the summer of 1959 all major decisions had been taken. By May 1960 the reinforcement details were defined and by July of the same year the labor schedule was established. The drawings are numbered and it is therefore relatively easy to trace back all design developments.

Nervi worked out multiple solutions for the elevations as well as for the precast roof panels. Today we read the isometric views of the reinforced roof panels, the rib beams, the truss girders, the center-line columns and the detailed forked column supporting the spine beams at Fort Washington Av. as witnesses of a job that was carried out almost entirely by hand. The computer of the Department of Mathematics of the University of Roma was used only when it was time to calculate the complex equations of the roof’s static system.
Everything else was worked out on paper. All details – reinforcement details, drainage details, framework details, and force diagrams – came together in a building that achieved a perfect score. It quickly gained great media coverage.

But even when the drawings clarify the design process, questions arise on how an Italian engineer that had never built anything in the United States and didn't speak any English got such an important commission in the first place. While the bulk of the drawings are in Parma, the photographic archive and the correspondences are part of the Pier Luigi Nervi Archive at the MAXXI in Rome, but there is no trace there. As Alberto Bologna pointed out in his well-researched Pier Luigi Nervi negli Stati Uniti 1952-1979, archival research doesn't allow today to piece together how Nervi got the commission. The archives of the Port of New York Authority were housed at the World Trade Centre and were destroyed on September 11th, 2001. Bologna anyway has devoted two chapters to Nervi’s presence on the America press and his relations with American cultural institutions since 1952, which is the year when Walter Gropius, Sven Markelius, Lucio Costa and Ernesto Nathan Roger selected him to work with Marcel Breuer and Bernard Zehrfuss on the project for the UNESCO building in Paris. In 1953 the project was also debated at the CIAM and Nervi got in touch with José Luis Sert who was by then Dean of the Graduate School of Design at Harvard.

Nervi's international network somehow reminded me about Othmar Ammann's political and entrepreneurial efforts in order to design and build the Washington Bridge (1923-1931). Doig and Billington's article have shed light on the topic as well as Doig's book Empire on the Hudson. Of course the thorough researcher won't stop at Ammann and will then start studying the work of Robert Moses, who also had a starring role in shaping New York's transit infrastructure. The controversies surrounding the Cross-Bronx Expressway case are particularly interesting in relation to the Washington Bridge and the Trans-Manhattan Expressway and open a whole different chapter of the research. I refer you to The Power Broker by Robert Caro.

Lets stay here on Washington Heights and mention “The Apartments” with their soot-repelling aluminum skin that was supposed to keep out pollution and noise. The buildings are one of the first highway air-rights developments in the United States and have been largely debated. While Nervi decided on an open structure that would allow for ventilation of the bus platforms inside and the expressway three levels below, Guenther and Brown created a sealed interior, "a protected space in an otherwise intolerable zone of the city." But the integrated interior ventilation and air conditioning system were dropped due to cost overruns and the levels of pollution remained always alarming. The article by David Gissen explains quite well the case.

This is just to say that the researcher can either choose what will or will not be included in the final narrative each step of the way, or get lost in countless tangents. I think it is important to acknowledge the complexity of each and every subject and take some time to get lost before defining a rigorous research agenda. We can eventually change our minds only by leaving our comfort zone.
