Augmented Reality (AR) is being used increasingly in both personal and professional spheres. The construction sector is not unaware of these technologies, although it is a fairly traditional sector. Augmented reality applications can contribute to have an effective, efficient and interactive construction management. Among all construction activities, in RIALTO we are targeting clash detection and defect management reporting on-site, during inspections and post-construction maintenance. In particular, our objective is to conceptualize and develop an Augmented RealIty based snag listing tool for the construction sector. A snag list is an auditing report used in construction projects, including a list of all the detected faults and defects in construction items. This report allows the people involved in the construction, operation and monitoring to locate defects easily for fixing them.
