Preliminary study for performance analysis of BIM-based building construction simulation system

A construction project is often uncertain and plans change frequently, so it is usually difficult to make a reliable and feasible plan. With the development of BIM technology, the future of the construction project can be simulated visually and a more reliable plan can be made. However, with BIM technology data production efficiency is low, since the data is utilized only for animation and visual presentation. Furthermore, although various construction simulation systems have been developed, these systems pose difficulties in terms of measuring performance. In this study, a methodology for analyzing the performance of a 4D building construction simulation system after defining the work process and standard scenario is proposed. the proposed methodology was verified by comparing the performance of the newly developed building construction simulation system and that of an existing commercial building construction simulation system.
