CONSTRUCTION MANAGEMENT TOOL AND METHODOLOGY USING 4D CAD SYSTEM FOR CIVIL ENGINEERING PROJECT BY INTEGRATION OF 3D OBJECT AND SCHEDULE

摘要

The present invention by constructing the parts and structures of the facility in a three-dimensional form in the construction, by continuously implementing the completion state by construction progress schedule in a three-dimensional shape, to visualize the process progress to significantly improve the construction process management work It relates to a 4D construction process management system and its implementation method.;To this end, the present invention has constructed an automatic terrain triangle network construction method capable of visual expression by color classification for each design part, and expresses the actual construction shape that changes every time by construction schedule as the actual state when expressing the three-dimensional shape such as cut soil. In order to develop a morphing technique for the system.;In addition, the present invention has developed a visual progress management representation technique that expresses the progress management status of the actual progress schedule compared to the planned construction schedule in three dimensions by varying the color for each part and structure for the delay and overtime schedule, and completed facility parts In addition to the 4D implementation, the virtual reality (VR) function was linked to show the actual use status such as simulation driving, and introduced the function to identify the problem in advance.;In addition, the present invention is configured to use the wireless communication function to obtain the 4D construction information on-site, key map that can selectively implement 4D on the screen from the wide range to the detailed structure range for the comprehensive 4D implementation of the wide-area site ) Function.;In addition, for the comprehensive 4D implementation of the wide-area site, a key map function was implemented to selectively implement 4D on the screen from the wide range to the detailed structure range.;In addition, the present invention is to perform the construction schedule calculation, three-dimensional configuration of each object, 4D implementation, virtual reality implementation functions are all performed by the standard process classification system code for the performance of these functions completed by construction schedule It is possible to implement integrated management of my information and to implement related functions for each level.
