Skanska used two autonomous Didge robots from Nextera Robotics at Kaye, a 31-story apartment tower in Seattle’s Belltown neighborhood. The machines did not build the tower. They navigated the site, climbed stairs and repeatedly captured high-resolution, 360-degree imagery. Nextera’s software then analyzed that imagery for construction progress, BIM alignment, quality issues and potential safety concerns.
The pilot’s clearest demonstrated benefit was reducing repetitive documentation work and giving remote project teams more frequent visibility into site conditions. The available evidence does not establish a quantified Didge-only reduction in Kaye’s total construction schedule, injury rate or project cost. Kaye was completed in June 2025, so this is best understood as a completed project pilot—not an active Seattle construction site.
The robots were watching construction, not performing it
The June 3, 2024 GeekWire report described two Didge robots moving through Skanska’s Kaye project. Nextera Robotics, headquartered in Boston, designed Didge as a mobile construction-site documentation and inspection platform.
That distinction matters. Didge is not a general-purpose robot laying brick, installing drywall or tying rebar. Its main job is to automate site walks and turn repeated visual captures into searchable project information.

Kaye occupies the 2200 block of Fourth Avenue in Belltown. The tower contains 324 apartments, spans approximately 260,619 square feet and rises 31 stories. Skanska served as both developer and builder. Construction began in winter 2023, and Skanska announced the project’s completion in June 2025.
During construction, the robots autonomously traveled through rooms, floors and work areas, including by climbing stairs. They returned to repeatable capture locations so teams could compare the same parts of the building over time. Skanska describes the workflow as daily site walks, photo documentation and quality and environmental, health and safety observations.
Captured imagery was uploaded to Nextera’s software, creating a remote visual record of the jobsite. That allowed project participants—including geographically dispersed architects and construction teams—to review conditions without relying solely on an in-person walk or manually assembled photo package.

Nextera’s visual-documentation product page describes this category of system as continuous site digitization. In practice, however, the Kaye workflow centered on scheduled autonomous captures and subsequent analysis, not uninterrupted live video surveillance.
How the AI turned photographs into project intelligence
Nextera says its machine-learning systems use neural networks for object detection, image segmentation and recognition of construction components. The system was described as recognizing items such as electrical boxes, conduits, air ducts and sprinklers.

The resulting data could support several construction workflows:
- Progress tracking: Teams could compare current imagery with earlier captures to see what had changed and which areas remained incomplete.
- BIM comparison: The software could compare observed site conditions with the building information model, or BIM—the digital model containing design and construction information.
- Quality assurance and quality control: Visual comparisons could help identify work that appeared incomplete, misplaced or inconsistent with the coordinated model.
- Remote coordination: Architects, engineers and project managers could share a common visual reference rather than working from disconnected photographs or occasional site visits.
- Safety observations: The system could flag configured conditions for human review.
BIM comparison is particularly useful when the project involves complex mechanical, electrical and plumbing coordination. Finding a deviation while a floor is still accessible may be less disruptive than discovering it after walls or ceilings have been closed.
But the software’s output should be treated as an aid to project controls, not as an authoritative description of everything happening on site. A camera may not see behind stored materials, inside wall cavities, above ceilings or into a tightly obstructed mechanical space. Conditions can also change between capture cycles.
The labor saving is clearer than the schedule claim
Skanska’s later innovation portfolio says manual image collection on Kaye previously consumed approximately 20 to 30 hours per week. GeekWire quoted a Skanska executive describing the equivalent human workload as as much as 40 hours per week.
Those figures should not be merged into one supposedly precise number. They may reflect different descriptions of the task or different points in the project. The defensible conclusion is that manual documentation required a substantial recurring staff commitment, and automation returned at least some of that time to the project team.

That does not prove that Didge shortened Kaye’s overall construction duration by a particular number of days or months. More frequent documentation could help teams identify coordination problems earlier, reduce rework and make decisions faster. Those are plausible mechanisms for schedule improvement, but the available Kaye reporting does not isolate and quantify Didge’s effect on the project schedule.

The available material does not identify that result as a Kaye outcome, so it should not be attributed to the Seattle tower.
Safety: an additional set of eyes, not a safety manager
The proposed safety workflow is straightforward:
- The robot captures repeated images of the site.
- AI reviews those images for configured conditions.
- The software produces a report or alert.
- A safety professional or supervisor investigates the finding.
- People decide what corrective action is required and verify closure.
Reported examples included missing gloves or other personal protective equipment, improper ladder use, uncovered floor openings and inadequate lighting. The system was also described as supporting observations related to OSHA requirements or client-specific rules.
This can make safety teams more efficient, particularly when a large site is difficult to inspect frequently. It may also create an audit trail showing what an area looked like at a particular time.
It cannot make a site safe by itself. An algorithm may miss a hazard outside the camera’s view, a temporary danger that arises after the robot passes, unsafe behavior that requires context, or a condition that depends on sound, touch or human judgment. It may also produce false positives. If alerts are too frequent or poorly prioritized, teams can develop alert fatigue and overlook important findings.

The practical value therefore depends on the complete loop: capture, analysis, severity ranking, human verification, assignment and corrective action. Didge is a detection and reporting aid—not a replacement for competent safety personnel, worker training, inspections or regulatory compliance programs.
A second robot handled a different construction task
Kaye also involved a Dusty Robotics FieldPrinter, used by a framing and drywall subcontractor. The contrast helps explain the different categories of construction robotics.
| System | Primary role | How it uses BIM |
|---|---|---|
| Nextera Didge | Observe, document, compare and flag | Compares visual site conditions with the model |
| Dusty FieldPrinter | Transfer digital layout into the physical site | Prints multi-trade layout information onto concrete slabs |
Didge connects the physical jobsite back to the digital model. FieldPrinter translates the model into marks that workers use in the field. Both reduce friction between digital construction planning and physical execution, but only FieldPrinter is directly performing a layout operation.
Dusty’s published Skanska case study reports figures including 50% faster layout, 75% less rework and more than three months of schedule compression. Those figures concern a separate three-story, 70,000-square-foot mixed-use medical facility. They should not be transferred to Kaye or treated as guaranteed results.

It demonstrates that:
- Autonomous visual documentation can operate on a large, multi-floor construction project.
- Repeated imagery can provide a shared remote view of progress and site conditions.
- AI can connect visual data with BIM, quality-control and safety workflows.
- Robots can remove a repetitive documentation burden from project staff.
It does not demonstrate that:
- Didge autonomously constructed the tower.
- The system eliminated human inspections or safety professionals.
- It reduced accidents or injury rates.
- It shortened Kaye’s schedule by a verified amount.
- Every hazard or model deviation was detected.
- The business case applies equally to every construction project.
The evidence base is also largely first-party: GeekWire reporting, Skanska’s project and innovation pages, and vendor descriptions and case studies. That is enough to explain what the deployment was intended to do and what users reported, but it is not an independent controlled study of safety or schedule outcomes.

When should a construction company consider this technology?
Didge is more likely to fit a large, multi-floor project with expensive coordination risks and a heavy documentation requirement than a small, short-duration job. Strong BIM practices and distributed project teams improve the potential value. So does having staff who can review alerts and act on them.
A site may be a poorer fit when access routes change constantly, temporary barriers and stored materials obstruct travel, the project lacks a maintained BIM model, or the documentation burden is too small to justify deployment.
Before purchasing or piloting a system, construction companies should ask vendors:
- How well does the robot navigate around changing barriers, debris, hoses, workers and equipment?
- What are the requirements for stairs, elevators, ramps, uneven surfaces and low-light areas?
- How often does a person need to intervene or remap the route?
- How frequently can the robot capture imagery, and how is that data organized by floor, room and model element?
- Which BIM formats and field-management platforms are supported?
- What are the measured false-positive and false-negative rates for each safety or quality detection?
- Who validates alerts, and how are issues assigned, tracked and closed?
- Who owns the imagery? What are the retention, export and deletion policies?
- How are worker privacy, facial images, signage, unions and workforce consultation handled?
- What is included in the quote: hardware, software, setup, training, connectivity, maintenance, integration and support?
Neither Nextera’s official site nor Dusty’s official site publishes a list price in the supplied material. Both use a sales-contact or quote-based buying path. A credible economic evaluation should include not only the robot or subscription fee, but also deployment, training, integration, human review, connectivity, maintenance and the potential value of avoided rework.
The right pilot metrics should be defined in advance. Useful measures include staff hours spent on documentation before and after deployment, time to identify and close issues, rework attributable to missed conditions, alert precision, human intervention frequency, coverage of planned areas and the percentage of findings that lead to verified corrective action.
The larger lesson
The Kaye deployment represents a practical near-term use of robotics in construction. Instead of trying to replace tradespeople, Didge addresses an information problem: project teams need a current, consistent record of what has been built, what has changed and what may require attention.
That makes the technology valuable when information gaps are costly. A robot that spends less time taking pictures and more time producing structured, comparable evidence could help skilled staff focus on coordination, decisions and corrective work. But the result depends on navigation, data quality, model discipline, alert management and human follow-through.

The most accurate description of the Seattle project is therefore not that robots built a high-rise. Two robots helped Skanska automate site documentation and connect visual observations to construction intelligence. That is less dramatic than autonomous building—but it is a more useful indication of where AI-backed robotics is delivering value today.
