Time-Space-Activity Conflict Detection Using 4D Visualization in Multi-storied Construction Project

摘要

This study investigated whether a 4D model can help project participants of construction sites to detect possible errors in construction process. Identifying problems in work sequence and elements are possible when necessary measures are implemented to rectify the problems in advance using a 4D model. The common problem associated with a construction project is a time-space conflict which may lead to project delays and cost overrun. Construction space management and activity sequencing are important aspects for timely project completion within an estimated budget. This research explored the effective use of 4D visualization that could help overcome timespace problems. In order to fulfill this research goal, a 4D model was developed that incorporated spatial requirements along a chronological schedule of events. The model produced logical evidence that a 4D model could effectively be usedin a construction site to detect time-space conflicts.
