Optimus Factory at Giga Texas: South Beam Reveals Final Building Length

Tesla's dedicated Optimus humanoid robot factory at Giga Texas is moving from steel skeleton to defined footprint. Drone footage captured on August 7, 2026 by aerial observer Joe Tegtmeyer shows two concrete milestones: the north perimeter grade beam is fully formed with distinctive rounded corners, and the emerging south beam now establishes the building's final length for the first time.

What the Grade Beams Tell Us

Grade beams are the reinforced concrete perimeter foundations that define a building's exact outer boundary — once they're poured, the footprint is locked. The north beam's rounded corners are a notable design departure from the sharp, angular perimeter of Giga Texas's main vehicle assembly building. It's a subtle architectural detail, but it signals that this structure was engineered from scratch for a distinct purpose rather than adapted from a prior template.

The south beam's emergence is the more consequential data point today. With both the north and south perimeters now visible, the full north-to-south length of the Optimus factory can be measured for the first time. Based on prior drone tracking, the factory's total length is expected to exceed 4,000 feet — a figure that, if confirmed by the south beam's position, would make this one of the largest single manufacturing structures Tesla has ever built.

How Fast Has This Moved

The pace of construction has been aggressive even by Tesla's standards. Official groundwork at the North Campus site was confirmed in late May 2026. By mid-June, the steel superstructure had cleared multiple floors in one section with seven cranes operating simultaneously. Drone footage from July 20 showed the steel frame had already stretched to 450 feet wide, expanding at an average of nearly 8 feet per day. The grade beams now emerging represent the transition from vertical steel erection to horizontal perimeter definition — the factory is closing in on its full intended shape.

The Scale Behind the Numbers

Context matters here. The Optimus factory is part of a 5.2 million-plus square foot expansion at Giga Texas. At full capacity, the facility is designed to produce up to 10 million Optimus units annually — roughly 27,000 robots per day. That production ambition is what justifies the sheer physical scale now visible from the air. A building exceeding 4,000 feet in length isn't overbuilding; it's the minimum footprint required to house the kind of automated assembly lines that would need to run continuously to hit those targets.

The grade beam stage also matters from a scheduling standpoint. Perimeter foundations typically precede interior slab work and utility rough-in — the next phases that will begin to reveal how the interior is being divided and serviced. Tegtmeyer's ongoing drone coverage has been the most consistent public record of this build, and the south beam's appearance marks the clearest visual confirmation yet that the factory's outer boundary is set. The next milestone to watch: whether the interior slab pour and any visible utility trenching begin to hint at the production line layout inside.
