The ARSC – Augmented Reality for Stone Cladding Safe Assembling Operation stems from the need of prevention of accidents on construction sites. Falls from height are the most common causes of serious accidents, often fatal, not only in Poland but throughout Europe. There is a great need of increasing Health & Safety level. The objective of the project is to decrease accident rate during construction of tall buildings, especially during stone cladding works. To achieve that goal training system containing manual and Augmented Reality (AR) software will be prepared. It will help fitters and engineers to access all needed information on H&S and gain knowledge on stone cladding technology.
