Autonomy moves from “nice-to-have” to necessity on construction sites
Gravis Robotics, a Swiss construction-technology company founded in 2022, is positioning autonomous heavy machinery as an increasingly urgent requirement for the construction sector, citing safety, labour constraints and the complexity of modern job sites. The company’s direction was highlighted in a new interview with Ryan Luke Johns, co-founder and CEO, featured in a special episode of the EU-Startups Podcast recorded during Leonard Launch Day in Paris.
The episode opens a five-part interview series produced in partnership with Leonard, the innovation and foresight platform of the VINCI Group. The series spotlights companies in Leonard’s 2026 cohort working across construction, infrastructure, energy and mobility—sectors where automation and digital tools are increasingly being tested under real-world constraints.
Why heavy-machinery autonomy is gaining momentum
In the interview, Johns argues that autonomy in heavy equipment is shifting from a premium feature to a baseline capability. The rationale is familiar to many contractors: projects are becoming more complex, timelines tighter, and safety expectations higher—while the availability of skilled operators remains a persistent challenge in many markets.
Autonomy, he suggests, is not primarily about replacing people, but about reshaping where humans add the most value. Instead of being physically present in high-risk zones or performing repetitive machine operations in hazardous conditions, operators may increasingly supervise, intervene, or manage multiple machines from safer positions.
Safety as a primary driver
A central theme of the conversation is the safety case for automation. Removing humans from the most dangerous parts of machine operation—particularly in environments with unstable ground, limited visibility, or heavy interaction with other equipment—can reduce exposure to incidents. The interview frames autonomy as a way to limit human proximity to risk rather than to remove human decision-making entirely.
Retrofitting vs. building from scratch: a pragmatic route to adoption
One of the most pointed takeaways from the episode is Gravis Robotics’ emphasis on retrofitting existing equipment rather than relying solely on purpose-built autonomous machines. Johns describes retrofits as a practical bridge between today’s construction fleets and the autonomous future many technology providers promote.
In construction, fleets are long-lived assets, and contractors often operate mixed brands and models across years or decades. A retrofit approach can, in theory, lower the barrier to entry by enabling autonomy on machinery already purchased, maintained and integrated into existing workflows. It can also reduce the friction that comes with introducing entirely new machine types that require new servicing arrangements, procurement cycles, and operator retraining.
The strategy also reflects how construction technology is typically adopted: incrementally, with solutions expected to work on “live” sites rather than controlled environments. Johns points to the need for systems that can be deployed without interrupting operations and that can handle the variability of construction settings.
Robotics on live construction sites: the hard part
The interview underscores that deploying robotics in construction is fundamentally different from automating in structured environments such as factories or warehouses. Job sites are dynamic, with changing terrain, weather, shifting work zones, and multiple subcontractors operating simultaneously. This complexity raises the bar for perception, planning, and safety systems.
Johns describes the “realities” of deployment as a major hurdle for any autonomy provider: machines must interpret messy environments, react to unexpected changes, and operate alongside humans and other equipment. In practical terms, that means autonomy systems must be robust enough to handle incomplete information and still behave predictably—requirements that go beyond a successful demo.
Human roles evolve alongside autonomy
Rather than presenting autonomy as a binary switch, the conversation frames it as a spectrum of capabilities. Operators may transition toward supervisory roles, focusing on oversight, exception handling, and coordination. This evolution can also create new training needs and operational procedures—particularly around handoffs between autonomous and manual control, safety protocols, and accountability on multi-contractor sites.
Leonard and VINCI: innovation pipeline meets job-site reality
The setting for the interview—Leonard Launch Day in Paris—signals the growing role of corporate-backed innovation platforms in shaping construction’s technology roadmap. Leonard, as part of the VINCI Group, sits close to large-scale infrastructure and construction operations, offering startups a pathway to test and refine products against real project demands.
For early-stage construction technology companies, access to operational contexts can be as valuable as capital. The episode positions Leonard’s cohort model as a way to connect startups with industry stakeholders who can validate whether new tools fit procurement realities, safety requirements, and site workflows.
Podcast sponsor highlights compliance automation trend
The episode is sponsored by Vanta, a trust management platform focused on automating security and compliance programmes. Vanta says it supports more than 12,000 companies and automates over 35 compliance frameworks, including SOC 2 and ISO 27001, along with governance, risk and compliance workflows such as risk management.
While not directly tied to construction autonomy, the sponsorship reflects a broader startup theme: as companies scale into enterprise and regulated markets, operational trust—security, compliance, and auditable processes—becomes a competitive requirement rather than an afterthought.
What to watch next
The interview with Ryan Luke Johns sets the tone for the broader series by focusing on the gap between autonomy’s promise and the operational hurdles of real-world deployment. For contractors and infrastructure owners, the key questions remain how quickly autonomy can be integrated into existing fleets, how safety cases will be proven on complex sites, and how roles and responsibilities will be defined as machines take on more tasks.
With four more cohort interviews planned in the series, the next episodes are expected to offer additional signals on where construction, mobility and infrastructure innovation is heading—and how quickly pilots may translate into scaled deployment.
