August 2023; An aerial perspective captures the sprawling scale of the horizontal construction sequence as the structure begins taking its organic shape across the site.. 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.
