Drone flyovers of Elon Musk’s new Advanced Technology Chip Fab (ATCF) in Texas, shared by flight instructor and drone videographer Joe Tegtmeyer, show rapid progress at the site. The fab was announced on March 21 this year, and Tegtmeyer states progress has “hit another gear.” In a post, he notes that GeoPiers are at work on part of the foundation that has had gravel mix placed on the top soil, with more work grading on the south end. A few days later, he reported that the foundation is expanding longer to the south, construction materials continue to be stockpiled, and “4 new permits were filed in the past few days for the large trailer complex that houses the general contractors and the temporary Tesla offices for the new facility.” Tegtmeyer clarifies that the ATCF is not the Terafab, which will be built ~ 100 miles or so to the East in Grimes County, Texas, but is the “smaller development facility that is the first part of the overall AI Chip development program.” The ATCF is a joint Tesla–SpaceX facility and a keystone for Tesla, SpaceX, and xAI accelerator chips, expected to combine logic, memory, and advanced packaging under one roof. Projects from here are destined to support Tesla cars and Robotaxis, Optimus robots, and upcoming Earth-orbiting AI data centers.
