Abstract

Research and practice have shown that by planning project production processes thoughtfully with systematic avoidance of waste, and by using appropriate production control systems, it is possible to improve work flow and productivity. In this process, collection and distribution of accurate, reliable and updated information describing the states of the construction processes and products is essential. This study examined the effect of an information system based on building information modeling (BIM) on the decisions made by construction trade crews when determining their sequence of work in different locations on site. A prototype system, called 'KanBIM', was used by subjects working in a virtual construction site experiment setup using a virtual reality CAVE linked to a discrete event simulation engine, to guide their performance of 'virtual' work in a building with sixteen apartments. Ten experiments were run with subjects using the system and ten control runs were performed without the system. The results indicate that use of the system improved the process flow and eliminated waste. The system gave the subjects situational awareness when selecting tasks for crews, leading them to perform the right work, reducing rework and time wasted in searching for tasks.
