“Building a Swiss Watch Out of Concrete”: Clark Construction on LACMA’s David Geffen Galleries

The recently opened David Geffen Galleries at LACMA are the result of more than a decade of effort across many fronts: the city, the county, the public, the architect, the engineers, the general contractor, and the many builders involved in translating an ambitious and visionary design into built form. The project has also been subject to unusually intense scrutiny, with responses ranging from admiration for its meticulous construction and architectural ambition to criticism of its scale, cost, concrete mass, and engineering complexity in earthquake-prone Los Angeles. Whatever one's position, the building remains an exceptionally sophisticated case study in how architecture is negotiated through construction.
This conversation approaches the David Geffen Galleries from the perspective of Clark Construction, the general contractor responsible for helping bring Peter Zumthor's design to completion. Carlos Gonzalez, Group President at Clark Construction, oversaw the construction process and shared with ArchDaily some of the technical, material, and logistical challenges behind the building. These range from its monolithic concrete structure and extensive post-tensioning system to the 56 seismic isolators that allow the building to move during an earthquake; from unpredictable ground conditions near the La Brea Tar Pits to the fabrication of solid bronze mullions and the integration of mechanical systems within the building's double-deck concrete structure.

Executive Summary

The David Geffen Galleries at LACMA resulted from over a decade of collaborative effort involving various city, county, public entities, architects, engineers, contractors, and builders translating the design into reality. The project faced intense scrutiny regarding its scale, cost, concrete mass, and engineering complexity in earthquake-prone Los Angeles. The perspective is offered through Clark Construction, whose Group President, Carlos Gonzalez, oversaw the build and shared technical challenges. These challenges included managing a monolithic concrete structure with an extensive post-tensioning system, integrating 56 seismic isolators, addressing unpredictable ground conditions near the La Brea Tar Pits, and fabricating solid bronze mullions within the double-deck concrete structure.

Full Take

The narrative centers on the friction between visionary architectural design and the material, logistical realities of large-scale construction, particularly in seismically active environments. The inherent tension lies in how ambitious aesthetic goals—like Zumthor’s vision—are mediated by tangible constraints: concrete mass, cost, engineering complexity, and site conditions. The transition from abstract architectural ambition to physical realization forces a confrontation between the theoretical ideal and the practical compromises inherent in building. The emphasis on Clark Construction's role shifts the focus from pure design critique to the mechanics of execution, highlighting how specialized technical solutions (like seismic isolators and post-tensioning) become inseparable from the final form. The intensity of external scrutiny suggests that such monumental projects act as crucibles where societal expectations regarding public works intersect with engineering limitations, often leading to polarized reception based on differing priorities—artistic merit versus structural pragmatism. What assumptions about the inherent harmony between complex design and its physical instantiation are being challenged by framing construction through a lens of intense technical negotiation? What costs, beyond financial ones, are absorbed by those who mediate between abstract vision and built form?
