Developing 5D System Connecting Cost, Schedule and 3D Model

A recent topic, BIM could be considered as an effort to integrate all the information. So far, the integration of cost and schedule data has been done successfully as there is a good case of EVMS in order to synthesize those data. There have been many efforts to develop a 5D system that integrates cost, schedule data and a 3D model, but its technology is so difficult that few have succeeded. The 5D system will have many advantages once it is made: The visualization of schedule data and verification of cost in real time are possible and the future cost and schedule can be expected accurately. Especially, in case of an atypical structure the clash of members and errors of drawings which are hard to find in 2D drawings can be detected and corrected in a 3D model. This paper presents the methodology and results to develop a 5D system with the integrated cost and schedule data from EVMS, and a 3D model of the 2nd Geumgang Bridge within nD-CCIR, a 5D system developed in the UK.
