In the new era of computerized building information, communication in a design and construction project demand transactions of large volume building model data containing various engineering domains, which causes increased costs in handling large data and communication problems due to poor understanding about which data should be shared. In this study, the(More)
In earthwork sites, its terrain shapes are changing continuously as the work proceeds. If someone wants to grab three-dimensional geometry data of such sites, currently available technologies such as 3D laser scanners are unable to collect reasonably precise data in pseudo-real time (i.e., 1-10 scans per second). To tackle the problem, the authors took(More)
