Construction site robot

HP SitePrint marks with an accuracy of under three millimetres. It takes the dimensions directly from the digital CAD drawings, so manual measuring with tape and chalk lines is no longer needed. A connected total station measures distances, angles and heights. On the hospital project for Acciona, the higher accuracy led to less rework and lower overall costs.

In the solution example, about six times faster than usual. At the Hospital Central do Alentejo, HP SitePrint achieved 225 m²/h, compared with 40 m²/h for the manual method with a two-person team. The entire layout process for almost two kilometres of drywall profiles was completed in 37 hours. This allowed workers to start installing the walls earlier.

Via cellular network, because building shells have neither Wi-Fi nor fixed lines. HP SitePrint uses Deutsche Telekom LTE, and abroad it relies on roaming agreements with more than 600 partners. This lets the robot load CAD plans from the cloud and report its condition and ink level to the service team. HP has used it this way from Düsseldorf to Nunavut in Canada without new contracts for each country.

Yes, wherever layout tasks arise. Berlin-based ArtLab Studios had to mark positions for lighting, sound and electrical systems across 8,000 square metres at Messe Düsseldorf. With HP SitePrint and just one person, the work was done in 9 instead of 16 hours. The more precise markings reduced errors, and last-minute changes could be incorporated without delaying the schedule.
