Field Operations Services Unlocked by One Person Supervising Multiple Machines

Demonstrations of one person supervising three machines point to a new layer of field operations services: defining work zones, managing changes, keeping records, and handling safety responses.

An Excavator With No One in the Cab Has Entered the Jobsite

Bedrock Robotics announced in August 2026 that it had deployed excavators without onboard drivers at a water treatment facility in Nevada and earthmoving sites in Texas. One site, operated by Zachry Construction, covers 1.2 million cubic yards.

Rather than building new excavators, the company adds sensors and work-decision systems to existing 20-to-80-ton excavators. It said that, under human supervision, it moved more than 65,000 cubic yards of soil and rock in 2025, then moved to commercial deployments with empty cabs in 2026. Its claim that installation can be completed within a day should be treated as a company claim; installation time and cost need to be checked for each site.

The larger cost shift may come from people rather than machines. In a solar piling demonstration published by the Australian Renewable Energy Agency, one person supervised up to three machines, reducing the operating staff needed per machine by about 67%. The result shows that a single person can potentially supervise multiple machines performing repetitive work.

Korea has reached an earlier stage of this transition. In a demonstration in Sejong 5-1 Living Area (세종 5-1생활권), a remote excavator achieved pipeline-trench productivity of 69.67 cubic metres per hour, nearly the same as 69.28 cubic metres for a conventional excavator. But the remote machine’s average error was 5.4 centimetres, larger than the 2.8 centimetres recorded by an auxiliary machine with an onboard operator. At the Yeosu Hwatae–Baekya road site (여수 화태–백야 도로), an excavator working on an island was operated from a control room on the mainland in 2025, though no cost savings were disclosed.

Fewer operating staff do not automatically mean lower total construction costs. In Korea, wireless remote-control equipment must stop automatically when its signal is lost and include an emergency-stop device. A separate process for inspecting the full process by which a machine identifies people and obstacles on its own is still being established. The costs of communications networks, surveying, safety zones, remote intervention, and incident records also need to be counted.

What Changes for a 12-Person Earthmoving Contractor

Consider Mr. Kim, the site manager at a 12-person earthmoving contractor. He defines the areas for three excavators, explains drawings and stake locations to operators, then checks depth and volume again after the work is complete.

Today, he finds work locations in design drawings, marks them in the field, and then copies the same information into paper work orders and mobile phone chat groups. Machine hours and photographs are entered again in daily logs, then gathered at month-end and turned into construction-payment claim materials.

The most time-consuming work is not the excavation itself but communicating changes. If underground pipes are found or rain softens the ground, the work sequence changes. If the message arrives late, crews may revisit completed areas or miss photographic and volume evidence.

With autonomous excavators, Mr. Kim would first mark work zones, target depths, soil placement locations, and no-entry areas on a map. Each machine would receive a work package that states where and how much to excavate. If a person or vehicle enters the area, or communications fail, the machine stops and alerts the responsible person.

During work, he sees the locations, progress, and reasons for stops across three machines on one screen. Completed areas are stored with time, depth, and machine status. Instead of reconciling notes and photos every evening, he can check only the areas with anomalies.

Much still requires human judgment. The actual location of underground infrastructure, soil conditions, slope-collapse risk, and whether other workers have entered the area must be assessed on site. Final surveying and work approval also remain human responsibilities. Teams must decide in advance who stops the machine and controls the site when a breakdown or incident occurs.

The first need, then, is not necessarily a single company that makes excavators. It is an operations service that turns a site into machine-readable work zones, communicates changes, and retains work and safety records. Because ground conditions and movement routes differ from site to site even for the same excavator, providers of this service could emerge outside equipment manufacturers.

Abroad, Companies Are Starting With Repetitive Work

Fortescue tested automated piling equipment at its Cloudbreak solar site in Western Australia. Each pile took an average of 2.61 minutes to install, and one person supervised three machines, reducing operating staff per machine by about 67%.

However, hard ground prevented piles from being driven directly, requiring drilling and backfilling first. The trial showed that headcount could be reduced, but site processes also had to be redesigned around the equipment.

At Holcim’s Lee Moor quarry in the United Kingdom, a 23-ton excavator fitted with Gravis Robotics equipment repeatedly loaded aggregate into a screening hopper. Holcim said it completed an average of 133 cycles per hour over two days, exceeding the target of 100, and handled 1,500 tonnes a day.

This case suited automation because the hopper and work zone were fixed and the motion was repetitive. Rather than automating every excavation task, it may be more practical to start with one task that has clear boundaries.

In the United States, Teleo supervised dump trucks at Tomahawk Construction’s Florida site from a control room about 64 kilometres away. The machines handled repetitive hauling, stopped in complex situations to wait for human intervention, and one person managed three vehicles.

This did not remove people entirely. It shifted their role from continuous driving to judging stopped equipment. An excavator operations service does not need to promise an unmanned site from the start; it can first sell intervention conditions and handover procedures.

Things You Could Build Now

1. Autonomous Equipment Site-Fit Assessment

  • A service that takes drawings and site photos, then separates areas suited to automated work from areas that are not.
  • It is for earthmoving contractors with 5 to 20 employees that are preparing to trial one remote or autonomous excavator.
  • As existing excavators can now be fitted with equipment, checks of communications, ground conditions, and site movement routes can determine adoption more than equipment purchase does.
  • The first screen should offer drawing upload and ask five questions: equipment type, repetitive work, pedestrian traffic, and communications status.

2. Map-Based Work Orders

  • A service that draws excavation limits and depths, soil placement locations, and no-entry areas on a site map, then sends the same instruction to machines and workers.
  • It is for site managers who manage three or more excavators and send drawing changes to operators every day.
  • For a machine to move on its own, verbal instructions must become work packages with clear boundaries and numbers.
  • The first screen should show a site map alongside blue work zones, red no-entry zones, and changes awaiting approval.

3. Work-Volume Evidence Records

  • A service that stores when, where, and how much a machine excavated, together with photos, depth, and reasons for interruptions, then turns the record into construction-payment claim material.
  • It is for contract administration staff at earthmoving subcontractors paid by excavation volume or pipeline length.
  • Automated equipment can continuously retain location and work results, which can also reduce the effort of rewriting logs by hand.
  • The first screen should show only today’s completed volume, volume awaiting client confirmation, and work with missing evidence.

4. Stop Alerts and Handover Management

  • A service that alerts teams when equipment stops because of an obstacle or communications problem, then connects the right responder: an on-site person or remote operator.
  • It is for equipment rental companies that send remote machines to island or mountain sites and manage several sites at once.
  • When one person is responsible for several machines, the reason for a stop and the site-handover record become more important than the normal-operation screen.
  • The first screen should list stopped machines by risk level and include buttons for site check, remote handover, and work cancellation.

One Person to Speak With Today

Call one site manager who recently managed excavation work for 20 minutes. Ask who receives work-zone changes, how they receive them, and how many times the same work volume is rewritten. If they have copied the same information into at least two of these places—paper logs, mobile phone chat groups, and construction-payment claim materials—and later checked for omissions, it may be worth testing map-based work orders or work-volume records before equipment control.

Why this matters where you are

The examples point to a change in work around machines, not just a change in the machines themselves. Check whether your own sites repeat the same work-zone information across instructions, logs, photos, and payment claims, and identify the stop conditions that still need human judgment. Local safety rules, communications coverage, ground conditions, and site processes may differ, so those constraints need to be checked before applying the model.
