Abstract

There is a great potential to improve the flow of resources through locations on construction sites, termed work-flow. Current activity-based scheduling techniques do not provide adequate support for the planning of work-flow due to practical and methodological reasons. Location-based scheduling techniques provide a promising alternative to activity-based scheduling techniques for planning of work-flow. However, neither location-based nor activity-based scheduling techniques provide users with insight in the spatial configuration of scheduled construction operations. A technique that can provide this insight is 4D CAD in which 3D CAD models are combined with data from construction schedules. This article presents a process method for the planning of work-flow by combined use of location-based scheduling and 4D CAD. We suggest that a location-based approach to 4D CAD can improve the usability of the 4D CAD models for work-flow analyses. In addition, the article suggests that 4D CAD can enhance the value of location-based schedules.
