The Guggenheim Museum Bilbao, which celebrates its twentieth anniversary this month, has been hailed as a pinnacle of technological progress since its October 1997 opening. While the use of the modeling software CATIA (Computer Aided Three-Dimensional Interactive Application) was without question groundbreaking, some of the greatest moments of ingenuity during the building’s design and construction were distinctly low-tech. Developed between 1991 and 1997, the curved and angular titanium-clad building was conceived at the turning point between analog and digital practice. This profound shift enveloped and permeated every aspect of the project, from the design process and construction techniques to the methods of communication technology put to use.

Standing on the Solomon R. Guggenheim Museum construction site in 1957, architect Frank Lloyd Wright proclaimed, “It is all one thing, all an integral, not part upon part. This is the principle I’ve always worked toward.” The “principle” that Wright referred to is the design ideology that he developed over the course of his seventy-year career: organic architecture. At its core, that principle was an aspiration for spatial continuity, in which every element of a building would be conceived not as a discretely designed module, but as a constituent of the whole.

Although not Wright’s intention per se, it is fitting that the building he conceived of as a living organism has evolved over time. The overall integrity and character-defining spiral form have remained unchanged, but there have been a series of additions and renovations necessitated by the growth and modernization of the institution.
