Methodology Using 4D CAD System for Civil Engineering Project by Integration of 3D Object and Schedule

摘要

In the present invention, parts and structures of a facility are constructed in a three-dimensional form in a construction work, and the completion state of each work progress schedule is continuously realized in a three-dimensional shape, thereby visualizing the progress of the process, Dimensional construction work process management system and its implementation method.;For this purpose, the present invention has constructed a method of constructing an automatic terrain triangle capable of visualization by color classification according to design part, and in real-time, The morphing technique was developed and implemented in the system.;In addition, the present invention has developed a visual progress management expression technique that expresses the progress management state of the actual progress schedule with respect to the planned construction schedule in three dimensions with different colors according to the site and structure for the delay and excess schedule, Along with 4D implementation, introduces the function to grasp the problem in advance by virtually showing the actual use state such as simulation running in conjunction with the virtual reality (VR) function.;In addition, the present invention constitutes a wireless communication use function for obtaining 4D construction information in the field. In order to realize a comprehensive 4D implementation of a wide area site, a key map capable of selectively implementing 4D on a screen ranging from a wide- ) Function.;In addition, a key map function that can selectively implement 4D on the screen from the wide area to the detailed structure range is constructed for the comprehensive 4D implementation of the wide area field.;Furthermore, in order to perform these functions completed according to the construction schedule, the present invention is configured such that the construction schedule calculation, the three-dimensional configuration for each object, the 4D implementation, and the virtual reality implementation functions are all performed by the built- Integrated management of my information and implementation of related functions at each level.
