The HP robot, known as SitePrint, prints lines and complex objects accurately and with consistent repeatability. It can also print text and thus bring additional data from the digital model to the construction site. It is designed to be autonomous and can avoid obstacles.

Sisk is testing the robot on its £227m contract to build two residential towers for Quintain Estates at Wembley.

Sisk head of digital project delivery, Shervin Deh Bozorgi, said: “This technology allows us to automate the printing process of layouts, gridlines or any other internal setting outs using [the robot] connected to a Total Station. Initial results have been impressive so stay tuned for more feedback in upcoming weeks.”

HP launched SitePrint last September. In total, more than 80 pilot projects have been conducted worldwide.
