Abstract: Many construction fatalities involving cranes and ground workers are caused by contact with objects and equipment, in particular being struck by crane loads and parts. One of the main risks in operating a tower crane is ...

Abstract: In several studies it is widely accepted that human error is the main reason for up to 80% of all incidents and accidents in complex high-risk systems that exist in the aviation, petrochemical, healthcare, construction, ...

Abstract: A more rapid and widespread use and implementation of technology in construction often fails since its benefits and limitations remain somewhat unclear. Project control is one of the most variable and time consuming task ...

Abstract: One-fourth of construction industry fatalities are caused by worker collisions with construction equipment. Nonvisible areas (blind spots) for equipment operators are contributing factors to many of these fatalities because ...

Abstract: This work studies the utility of ultra wideband (UWB) sensor technology for optimizing construction site operations. In particular, recorded trajectory signals provide important behavioral information regarding site usage ...

Abstract: Visual monitoring of construction worksites through the installation of surveillance cameras has become prevalent in the construction industry. These cameras also are useful for automatic observation of construction events ...

Abstract: In this paper, we examine the potential of a range camera in construction material sorting applications. By utilizing the depth information from a time-of-flight (TOF) camera, we identify and classify objects placed on a ...

Abstract: Previous research and applications in construction resource optimization have focused on tracking the location of material and equipment. There is a lack of studies on remote monitoring for improving safety and health of ...

Abstract: Awareness of the construction environment can be improved by automatic three-dimensional (3D) sensing and modeling of job sites in real time. Commercially available 3D modeling approaches based on range scanning techniques ...

Abstract: Nanotechnology research and product development are actively conducted in many industries, (such as industries that manufacture advanced materials and semiconductors) and in medicine. Few studies have presented the potential ...
