If you’ve ever passed by a construction site and spotted an excavator moving dirt, chances are you assumed there was a skilled operator at the controls. However, in certain areas of Texas and Nevada, that’s not the case anymore.
Bedrock Robotics, based in San Francisco, has introduced autonomous excavators that can conduct actual earthwork without any human operator inside. The company claims this technology emerged after a year of testing on live job sites with supervision from human workers.
It’s one thing to see AI taking over simple software tasks, but watching it effectively manage a large excavator on a construction site? That’s a game changer. Bedrock believes this innovation could help contractors tackle labor shortages and enhance project efficiency. Let’s take a closer look at how this technology operates and the prospects ahead.
Bedrock’s excavators are beginning to show their worth
According to Bedrock, their excavators are already operational on significant infrastructure projects. For example, one is part of a water treatment facility project in Nevada, while another in Texas is involved in a large earthwork project with Champion Site Prep.
Additionally, there’s a substantial civil site work project underway with Zachry Construction Corporation. The current tasks focus on early earthmoving and foundation preparation. Bedrock is concentrating on tasks like clearing earth and rough cuts before diving into more meticulous work. This strategy seems logical, as delays in early earthwork can impact the entire project timeline.
Are these machines nearing human productivity levels?
Bedrock assesses the efficiency of its excavators based on the volume of earth moved during a shift. The productivity bar is influenced by the project’s specific needs, soil conditions, and the equipment being utilized. However, a spokesperson mentioned that as of their deployment in August 2026—just two years post-founding—they’re already approaching productivity comparable to human operators.
A look at the technology behind Bedrock’s excavators
Bedrock’s system, known as the Bedrock Operator, can be retrofitted onto existing heavy machinery. This means crews can install the required sensors and computing equipment in about a day, without any lasting modifications to the excavator. After a site manager establishes the initial work plan, the software takes control of the digging tasks. The machine-learning technology is designed to assess the job site and make informed movement decisions.
Bedrock claims they’ve trained this system through extensive fieldwork. However, it’s worth noting that the current rollout involves new excavators that were outfitted and tested at the company’s facilities. When inquired about the system’s compatibility with contractors’ pre-existing machinery, a spokesperson mentioned there aren’t any updates yet, but they hope to share more soon. The focus on retrofitting remains central, and the fully autonomous deployments are still in preliminary development.
Human oversight is still a factor
Seeing an excavator operate without anyone inside might unsettle some individuals. Bedrock recognizes that establishing safety is crucial for future expansion and emphasizes that safety is their top priority as deployment efforts grow. These machines are programmed to self-monitor and can request assistance if they encounter issues.
When asked how often human intervention is necessary, a spokesperson explained that it’s quite rare. If an excavator encounters an obstacle or gets stuck, a human monitoring the operation can step in briefly until the machine resumes its functions autonomously.
Moreover, Bedrock keeps someone informed during these operations, ensuring that human support is always accessible without requiring a person to be stationed in the cab all day. This is especially vital on active job sites, where people and other vehicles are frequently present.
The safety features are also automated. If a person or an unauthorized object approaches too closely, the machine will stop on its own until it’s safe to proceed, all without needing manual input.
Bedrock’s choice of excavators
Bedrock specifically chose excavators as the starting point for its technology due to their significant role in a contractor’s fleet—often representing about 25%. Moreover, mastering the operation of excavators can take several years.
They estimate that operators may need around five years of training to develop full proficiency, resulting in a staffing challenge for contractors. Autonomy aims to handle these repetitive, labor-intensive tasks, allowing skilled operators to focus on more specialized roles or oversight duties.
While we’ve seen autonomous excavators before—like the robotic HEAP excavator that constructed a stone wall—what’s compelling about Bedrock is that their machines are actively working on real construction projects.
Worker shortages are a growing concern in construction
The increasing investment in this technology makes sense, given that Bedrock has raised over $350 million. Their founding team includes former engineers from Waymo, who bring years of experience in autonomous vehicle technology.
Construction firms are grappling with a shortage of skilled labor. Industry estimates indicate nearly 20% of construction workers are over 55 years old, and over 40% of the workforce is poised for retirement within the next five years. Moreover, research shows that 92% of companies with craft positions are having trouble filling certain jobs, which might pose challenges as demand for construction remains robust.
Cost overruns are another concern, with a McKinsey analysis noting that major construction projects often exceed schedules by 20% and budgets by up to 80%. Additionally, safety is a significant issue; construction sees a disproportionately high number of workplace fatalities. While automation may reduce risks, companies still need to demonstrate the long-term safety of using autonomous machines around people.
Interestingly, Bedrock emphasizes that they don’t envision operators becoming obsolete. In the immediate future, these autonomous machines are expected to work alongside human crews since there simply aren’t enough qualified operators for every project. Over time, it’s likely that some experienced operators will transition to supervisory roles overseeing autonomous equipment, somewhat akin to being a foreman for machines. Yet, there’s still a place for those who want to operate equipment directly.
Future aspirations: collaboration among machines
Looking ahead, Bedrock envisions a future where multiple machines on the same job site work in tandem. Co-founder Kevin Peterson described a scenario where an excavator collaborates effectively with a bulldozer, truck, and grader. Instead of operating individually, the connected fleet could streamline overall project management, significantly impacting scheduling. A site manager might set the goals, while the coordinated fleet decides on the methods to achieve them.
This unified approach is still a work in progress, with Bedrock initially focusing on scaling excavator deployments and broadening the tasks their systems can handle.
Considerations for the future
Here’s why this technology might be relevant to you: construction delays can impede the progress of new housing, roads, and water systems. If autonomous machines can keep earthwork moving amid a skilled labor shortage, it could lead to faster project completions and closer adherence to timelines.
Bedrock envisions a future where autonomous equipment complements human operators rather than replacing them. Currently, this could help existing crews with repetitive tasks, while some seasoned operators may eventually supervise groups of autonomous machinery, while others continue hands-on work in cabs.
Of course, there are still hurdles, such as obtaining permits and managing material shortages that can slow progress. Skilled workers will continue to be essential for planning, executing specific tasks, and navigating situations the technology can’t yet handle.
It’ll be interesting to see if that near-human productivity claims hold as these excavators enter additional job sites. Bedrock notes that human intervention is rare now, but it’s also worth considering how that might shift when one person oversees a larger fleet.
Safety will be critical, too. It raises the question of what happens when unexpected elements appear in the work zone. As we increase the number of autonomous machines operating around people, having a solid record of safety will be paramount.
Key takeaways
What’s striking about Bedrock is that they’re not just talking about what autonomous excavators could do in the future—they’re already executing paid work on active construction sites without operators inside the cab. They claim the machines are nearing human-level productivity, and that human intervention is “relatively rare.” Those are promising indicators, but it’ll be essential to see how these assertions stand up across various projects over time. It’s also reassuring to hear that Bedrock doesn’t anticipate the complete elimination of operator jobs. If these machines can help manage workloads while allowing skilled operators to tackle more challenging tasks or oversee their operations, it could be beneficial for both the workforce and the projects they contribute to. The real challenge lies in further integrating these machines into the workforce while ensuring safety and productivity remain high.
