Abstract: The A ugmented R eality technology has developed across many different fields and attracted a lot of attention as an approach to increase the efficien cy of construction projects in the field of civil engineering for the last ten years. This study thus set out to develop an AR system called AR Navigator to increase the efficiency of excavators with t he use of AR technology. The AR Navigator was designed to perform three major functions to offer three types of visual information and provide excavator operators with information about changes to the field of excavation, distance between a bucket and the ground and between a bucket and the plan side, and the maximum operating radius of an excavator at an arbitrary posi tion. The development of the AR Navigator would hopefully help to increase the efficiency of excavation works and ultimately establish a basic system for construction automatio

Abstract: Low income unreinforced masonry structures in the southwestern region of the Western Cape Province of S outh Africa present a safety and economic threat if subjected to moderate intensity seismic activity. Previous experience and investigations conducted have shown the vulnerability to damage and/or collapse when these structures are subjected to moderate se ismicity. Most unreinforced masonry buildings in South Africa were constructed prior to the first codified provision for seismicity contained in SABS 0160 of 1989. Numerous other residential unreinforced buildings were constructed since then. To date these types of structures have not been evaluated for South African conditions, and concerns have been expressed whether these structures conform to the new codified guidelines contained in SANS 10160 - 4 of 2011, which is almost a verbatim repetition of the Euro pean code for seismic design. Before an analysis of unreinforced masonry buildings can be conducted, it is imperative to det
