With works such as the Alamillo Bridge in Seville, Spain and the footbridge over the River Nervión in Bilbao, Santiago Calatrava has established himself as the most innovative and influential bridge designer of our time. These structures have shaped the way we understand works of civil engineering, making it much more difficult for public authorities to ignore the aesthetic impact of such large structures on our cities and landscapes. But when Calatrava applies this same expressive flair to building designs, his artistic authority begins to waverat least in the eye of this observer. While his bold structural experiments, often inspired by the study of animal skeletons, plants and other natural forms, have expanded the narrow formal vocabulary of civil engineering, in his buildings, this use of zoomorphic forms has too often resulted in works that can seem overbearing, lacking in human and urban scale, and even grotesque.
A case in point is the Tenerife Concert Hall, with its bold cantilevered arch that surges over the building, an admittedly functionless, expressive gesture [RECORD, February 2004, page79; Archrecord.com, Project Portfolio, February 2004]. What is this form meant to suggest? Is it an enormous breaking wave, as Calatrava has sometimes implied, an orchid blossom, an exaggerated feather in an exaggerated cap, a tentacle, an enormous muscular tongue? Calatrava deliberately avoids any specific symbolic reference, and leaves the associative process open to the imagination of each visitor. But does he take sufficient artistic control of the full suggestive power of the gesture, and of the darker images it can invoke? The same question could be raised to a greater or lesser degree with previous works such as the rail station at the Lyon-Satolas Airport in France (1994), the City of the Arts and Sciences complex in Valencia, now nearing completion, and the Milwaukee Art Museum [RECORD, March 2002, page 92; Archrecord.com, Project Portfolio, March 2002].
When Frank Gehry also engages in dreamlike images, as in the suspended conference room in the atrium of his DG Bank in Berlin [RECORD, October 2001, page 120; Archrecord.com, Project Portfolio, October 2001], he knows exactly what effect his work will provoke; its sinister chill is a deliberate part of his artistic response to the commission and to its context beside the Brandenburg Gate. Some critics such as Alexander Tzonis have defended the darker overtones of Calatrava's forms as surreal, comparing them to the work of artist Salvador Dalí and filmmaker Luis Buñuel. But there is nothing in the context of these commissions or in Calatrava's public statements about them that supports an intentionally surreal or critical undercurrent. His artistic intentions rather appear to be entirely positive and celebratory.
On the other hand, when Calatrava's buildings are not reaching for operatic heights, they often fall into a routine of vaults and curves, a formal language that seems seductively glamorous at first but exhausts its charm through repetition and an excess of symmetry, creating spaces that are often in fact quite dull and uninviting. A case in point: the galleries and other secondary spaces of the Milwaukee Art Museum.
In my view, Calatrava has run up against the limitations inherent in his attempt to develop a full architectural vocabulary based solely on a handful of structural ideas and metaphors and a relatively unstructured process of imaginative invention. His sources in 20th-century structural experiments are strongranging from Antoní Gaudí to Eduardo Torroja, Robert Maillart, Félix Candela, Pier Luigi Nervi and Eero Saarinen. But architects need to draw on many other cultural resources and traditions to make a building a complete cultural artifact. When such senstive cultural cueing is missing, the result can be the scaleless gestures and vacuous secondary spaces found in Calatrava's work, a problem also found in some of the works of his structural masters, such as Nervi.
If this argument seems too intuitive, one can compare
the Tenerife Concert Hall to the work of Norman Foster, another architect
strongly influenced by engineering. When an apparently arbitrary form
appears in Foster's work, such as the unusual mirrored polyhedron that
descends from the top of the Reichstag dome, it turns to be a device for
getting natural light down into the parliament chamber below. Function
disciplines expression, and keeps back the phantoms of unconscious suggestion.
