Section 2. Site Revolution: Machines Building the Future
After creating digital blueprints, the next stage of automation moves directly to the construction site. Implementation of physical technologies – from 3D printers to drones and robots – has the potential to radically change the appearance and efficiency of construction work. Analysis shows that Ukraine is at different stages of mastering these technologies, demonstrating both impressive successes and realistic challenges.
2.1. Construction 3D Printing: From Pilot Projects to Scalable Solutions?
Additive manufacturing technology in construction involves layer-by-layer application of special concrete mixture by a robotic manipulator (printer) to erect walls and other structural elements directly on site. This approach has already found application in Ukraine in landmark projects demonstrating its potential.
The most resonant was the 3D UTU company project in Irpin, where a 130 m² house was printed for a fallen soldier’s family. The building walls were erected in just 58 motor hours, becoming a powerful symbol of rapid recovery and social significance of new technologies. More ambitious is the project to build a new wing for School No. 23 in Lviv, initiated by Team4UA foundation with participation of the same 3D UTU. This facility is set to become the world’s largest educational building constructed using 3D printing.
However, the Lviv project itself serves as an important lesson. Despite walls being printed in record time (about 48 hours), overall project implementation faced significant delays, lasting years instead of the initially announced few weeks. This highlights a critical “implementation gap”: the speed of one technological stage is negated by bottlenecks in other, non-automated processes – foundation laying, roof installation, utilities connection, logistics, obtaining approvals, and external factor impacts such as power supply interruptions. Success of future projects will depend not so much on printer speed itself as on the ability to integrate it into an optimized end-to-end workflow.
Key players have already formed in the Ukrainian market, such as 3D UTU and UCAT3D, offering both printing services and equipment sales. Specific price guidelines are also emerging: 3D UTU estimates ready house cost at approximately $700 per m², including foundation, walls, roof, windows, and doors. The main technology advantages – wall construction speed, architectural freedom, and waste minimization – are undeniable. Meanwhile, high initial equipment costs and logistical complexities remain barriers to mass adoption.
2.2. View from Above: Drones as a Mature and Indispensable Tool
Unlike 3D printing, unmanned aerial vehicles (UAVs or drones) have already become a mature and widely implemented technology in Ukrainian construction. Their popularity is due to relatively low cost, ease of use, and immediate, quantifiably measurable returns. Drones are used at all project stages: for topographic surveying before work begins, for regular construction progress monitoring, for inspecting hard-to-reach and dangerous objects (roofs, facades, high-rise structures), and for creating accurate 3D models that are then integrated into BIM.
Drone efficiency is confirmed by specific numbers. Their use allows reducing time for geodetic work by 80-85% – tasks that previously required weeks are now completed in one or two days. This leads to direct cost savings: topographic survey costs can decrease from 100-150 thousand UAH to 40-60 thousand UAH. Overall, process optimization thanks to drone-obtained data can reduce total project budget by 20%. Equally important is safety improvement, as drones eliminate the need to send people for high-altitude and risky inspections. Several companies operating in the Ukrainian market provide professional drone services for construction, indicating maturity of this segment.
2.3. Next Frontier: Ground-Based Robotics
If drones are already present reality, ground-based construction robots represent the future that Ukrainian industry is still only observing. Global innovations in this field are impressive. The robotic mason Hadrian X can lay up to 360 blocks per hour, many times exceeding human productivity. Multifunctional robots from companies KUKA and Baubot can perform a wide range of tasks: drilling, grinding, painting, and transporting loads up to 500 kg. Four-legged robots like Spot from Boston Dynamics autonomously patrol construction sites, collecting data for monitoring and comparison with BIM models, working in conditions dangerous for humans.
Against this backdrop, Ukrainian reality looks contrasting. Labor market analysis and construction company price lists indicate total dependence on manual labor. Detailed rates for brick and block laying demonstrate that this process remains exclusively manual, and its cost is a significant budget component. Currently, there is no evidence of advanced ground-based construction robots being used in Ukraine.
This gap is explained by several factors. First, extremely high equipment costs, measured in millions of dollars, which is an insurmountable barrier for most companies under wartime conditions. Second, absence of qualified operators and maintenance engineers. Third, robots require a highly structured and predictable environment resembling a factory floor, not a chaotic construction site, especially under reconstruction conditions.
Different levels of these technology implementations – drones, 3D printing, and robots – are not accidental. They clearly reflect the technology maturity and accessibility curve. Drones, as relatively inexpensive tools that easily integrate into existing processes and provide quick returns, have already become a mass phenomenon. 3D printing, requiring larger investments and process changes, is at the pilot project stage. Ground robotics, requiring colossal capital investments and complete workflow restructuring, remains at the conceptual level for Ukraine. This suggests a logical strategy for companies: start with mastering mature technologies like drones and BIM to accumulate experience and generate savings that can later be reinvested in more disruptive technologies.
