Abstract
As the CALS/EC has been improved in civil engineering construction, the various drawings, such as CAD data, and plan documents have changed into electronic processing. These data or information have used and have exchanged between clients and contractors. Furthermore, with the generalization of the survey technique using GPS, those data have applied to GIS in order to use form management or maintenance.
Based on these backgrounds, this paper reports the new construction management system, which used Web-GIS at the earthwork site, and verifies the availability in using this system.
