Santiago Calatrava: Architecture, Engineering, and Design Legacy

Introduction: Santiago Calatrava and His Place in Modern Architecture

Born in Valencia in 1951, Santiago Calatrava is one of Spain's most celebrated architects. His works and projects can be found throughout Spain, as well as across Europe and in North America. Among his most famous works are the BCE Place Mall in Toronto, the Bach de Roda Bridge in Barcelona, the Oriente Railway Station in Lisbon, the Bridge of Europe in Orléans, France, and the Milwaukee Art Museum in the United States. In addition to his architectural output, Calatrava has also staged exhibitions of his sculpture in Florence, Texas, and Athens.

Core Design Philosophy and Engineering Approach

Calatrava implemented his innovative and original ideas through his many works. The major concepts of his design are expressed most clearly in his bridges and buildings. His importance in the community of European architects can hardly be overstated, yet he rarely designs a fully enclosed building; his works are generally open structures. Calatrava's dual capacity as an engineer and an architect allows him to capture the creative and structural aspects of both disciplines. His engineering skills enable him to apply his ideas to his architecture with greater ease.

The sculptural surfaces and unusual spaces born of this marriage of disciplines give Calatrava an unmistakable and easily identifiable style. He dismisses the apathy involved in accepted architectural form. In 1979, he received the Auguste Perret Award for his efforts to reintroduce the quality of Perret's work and for stressing the importance of primary structure in form definition.

Calatrava knew what changes architecture needed to undergo and the heavy demands involved in implementing such changes. Over the years, he gained excellent repute in the international community of architects, primarily for his integration of aesthetics and technology and for his production of dynamic structural forms that directly challenge conventional engineering and architectural practice. His cultural and educational background had profound effects on his intellectual orientation. The name Calatrava itself is a medieval aristocratic one, passed down from a generation of knights. The rich cultural environment of his native Valencia, his partial disillusionment with the direction of his initial formal education, and the clinical, mathematical world of Zurich's engineering institutes helped him pioneer a new architectural concept (Architect Week, 2000).

Major Works: Stadelhofen Station and Campo Volantin Footbridge

Two works stand as particularly strong testaments to Calatrava's ideas and concepts: the Stadelhofen Railway Station in Zurich and the Campo Volantin Footbridge in Valencia. The Stadelhofen station was completed in 1984, constructed with steel frames and glass in a modern style suited to its urban context. Its most notable feature is the glass-roofed canopy developed with counterpoised steel. The structure is built with conflicting features that reflect the site on which it was constructed — a factor said to have stimulated Calatrava's wit and structural creativity. The geometric implications of the work are another direct result of the layout of the land beneath it. The lateral curvatures and inclinations, directional changes, and site location gave the architect remarkable opportunities to experiment with space and dimension. The natural backdrop, civic milieu, and external environment of the station are all cleverly blended to achieve maximum unity.

The Campo Volantin Footbridge is another example of Calatrava's work that fully implements his unique approach to architecture and engineering. Built as a steel inclined parabolic arch with glass decking, the bridge is a brilliant example of light, modern urban waterside architecture. Like the Zurich station, it combines an apparent disequilibrium and geometric dynamism with stationary perspective and frozen movement, culminating in an astounding unity of form (Matthews, 2003).

Calatrava's most recognized genius lies in his ability to blend art and function, architecture and engineering. Shortly after completing the Zurich station — one of his earliest works — he undertook the design and construction of the Bach de Roda Bridge in Barcelona, commissioned for the Olympic Games to be held in the city. As the event was one of universal appeal, Calatrava took special care to clearly express all his innovative ideas in the structure. With its double arches, structural rigidity, and lightness of form emphasized through the steel and concrete support, the resulting bridge won him international acclaim and cemented his position among the leading architects of the world.
