BIM- and 4D-based integrated solution of analysis and management for conflicts and structural safety problems during construction: 2. Development and site trials

In order to achieve the information-based integrated construction management, e.g., time-dependent structures analysis, schedule/resource/cost conflict analysis as well as dynamic collision detection amongst site facilities and main structure elements, an integrated archetypal system named 4D-GCPSU 2009 is developed. Through 3 project examples, it is verified that the integrated solution is able to assist construction managers or owners in the aspects of analysis and management for process conflict and structural safety problems during construction. The application outcome of the system is accepted and praised by users as they considered that the system functions and analysis results provide significant reference support to the approval and revision of construction proposals, increase efficiency and safety concerning building construction. They also point out some difficulties in practice. As for those difficulties mentioned, a series of solutions plus further development orientation are put forth.
