Construction sites in Texas and Nevada are seeing a new type of heavy machinery at work: autonomous excavators with no operator in the cab. San Francisco-based Bedrock Robotics has deployed its driverless machines to perform real commercial earthwork, a development that follows a year of testing with human supervision on active job sites.

This advancement moves artificial intelligence beyond software tasks and into the physical operation of large-scale construction equipment. Bedrock Robotics suggests this technology could help contractors mitigate worker shortages and improve project timelines.

Autonomous Excavators on Active Projects

Bedrock's operator-free excavators are currently engaged in major infrastructure projects. In Nevada, one machine is contributing to a water treatment facility project in partnership with Sundt Construction. Meanwhile, in Texas, Bedrock is collaborating with Champion Site Prep on an extensive earthwork project involving millions of cubic yards of material. The company is also involved in a 1.2 million-cubic-yard civil sitework project with Zachry Construction Corporation, focusing on initial earthmoving and foundation preparation.

The current work emphasizes rough earthmoving, including clearing, cut-and-fill operations, and initial cuts, which are critical early stages of any construction project. Delays in this phase can have cascading effects on subsequent project milestones.

Productivity and Technology

Bedrock Robotics measures excavator productivity by the volume of earth moved per shift. A company spokesperson indicated that as of August 2026, the autonomous machines are achieving productivity levels nearing those of human operators. The technology enabling this is the "Bedrock Operator," a sensor and computing system designed as a retrofit for existing heavy equipment. Bedrock claims its package can be installed within a day without permanent alterations to the machine. Once a site manager inputs the project plan, the software autonomously manages the digging operations, utilizing machine learning to understand the surroundings and execute complex tasks.

The system was trained on tens of thousands of hours of field data. While initial deployments involve new excavators outfitted and tested by Bedrock, the company plans to make the retrofit system available for contractors' existing equipment, though a timeline for this has not yet been announced.

Safety and Human Oversight

Bedrock acknowledges that the sight of an unoccupied, operating excavator may raise safety concerns. The company emphasizes that safety is paramount and is integrated into the system's design. The machines continuously monitor their progress and can alert for assistance if they encounter issues. Human intervention is reportedly rare, typically required only when a machine encounters an unusual situation or becomes immobilized. In such cases, a remote fleet monitor can briefly intervene until the autonomous system resumes operation.

Bedrock's system includes an automatic safety response: if a person or an unauthorized object comes too close to a machine, it will halt operations until the area is clear, requiring no manual input. This ensures autonomous machines can operate safely around dynamic work zones with moving equipment and personnel.

Addressing Industry Challenges

Bedrock chose excavators as its initial focus due to their significant role in construction fleets, accounting for approximately 25% of a contractor's equipment. Mastering excavator operation can take five years or more, contributing to a challenging staffing landscape. The company aims for autonomous systems to handle repetitive earthmoving tasks, allowing skilled human operators to focus on more complex jobs or supervision.

The construction industry is facing a significant worker shortage, with estimates indicating a substantial portion of the workforce nearing retirement age. Simultaneously, demand for construction projects remains high. This confluence of factors, coupled with potential project delays and budget overruns common in the industry, creates a strong market for automation solutions.

Bedrock Robotics has attracted significant investment, with its founding team including former engineers from autonomous vehicle companies. The company asserts that its technology is not intended to replace human operators but rather to work alongside them. In the near term, this could provide much-needed support for existing crews, and in the longer term, experienced operators may transition to roles overseeing autonomous fleets.

Future Aspirations

Beyond individual machines, Bedrock envisions a future where multiple autonomous construction vehicles, such as excavators, bulldozers, trucks, and graders, can coordinate their operations on a job site. This integrated approach, managed by software, could fundamentally alter project scheduling and execution, with site managers setting goals and the fleet determining the optimal workflow.

This coordinated model remains part of Bedrock's long-term roadmap, while the company currently focuses on scaling excavator deployments and expanding the capabilities of its autonomous system.
