Geospatial construction data collection using GPS

Abstract

Besides productivity improvement, the enhanced safety, improved quality, and reduced road user costs have motivated the development of automated systems in construction data collection using emerging technologies. Global Positioning System (GPS) is currently employed to become one of the solutions to promote high productivity and cost savings in U.S. construction industry, especially in the area of earthmoving activity over the past few years. Thus, there is need to investigae the overseas GPS implemented case towards its application in Korea. The overall objectives of this study are to analyze the advanced earthmoving system using GPS, and compare the work procedure and property of both the traditional and the advanced earthmoving systems, which can show how the GPS implementation is beneficial for geospatial construction data collection. It is found that the dozer or grader operator is in total control of the earthmoving work in the advanced earthmoving system using GPS, guided by a screen conveniently equipped in the dozer or grader. Accordingly, the operator can get the information about the amount of cut and fill conditions with precise grades, which can finally achieve the productivity improvement by the simplification of procedure due to the deletion of automated work tasks.
