ACCIONA is using an autonomous robot (HP SitePrint) on the construction of the Alentejo Central Hospital in Évora (Portugal). It is the first time a Spanish infrastructure company has continuously employed this type of autonomous equipment to improve the efficiency of setting-out tasks on a worksite—that is, transferring the data on the plans to the physical site. It also marks the first use of this class of equipment in Portugal.

Six times faster than the traditional method

Thanks to the robot, ACCIONA has accelerated the pace of partition installation, achieving a setting-out speed six times higher than the traditional method.

Working from plans uploaded to the robot’s operating system, the unit can directly print lines and text onto surfaces. Its collaborative design does not replace the human operator, whose role in preparing the plans and operating the equipment remains essential.

Mobility, precision and autonomy

The robot consists of a compact mobile unit fitted with wheels and a printhead specifically developed for this application. Its high performance and degree of autonomy significantly speed up execution while maintaining the required line-marking precision and reducing surveyors’ physical strain.

Large-scale validation

By introducing this robot, the company has addressed one of the project’s main construction challenges: executing the building’s interior divisions across a slab area of 140,000 m². Thanks to its use, ACCIONA has already completed more than 25,000 m², validating the effectiveness of this new technology and its suitability for large projects.

The new Alentejo Regional Hospital in Évora will provide the region with modern technical–care units, inpatient and outpatient services, and will serve more than 200,000 people.

The project includes a ten-story building with capacity for 400 beds, the development of 127,000 m² of green areas, and the construction of a helipad and extensive parking facilities, among other works. With an investment of approximately €149 million, it is ACCIONA’s largest construction project in the country. Completion is scheduled for 2025.
