Modelling the spatial temporal utilization of Construction Space Requirements using 4D CAD

Abstract

This paper presents a new modelling methodology for Construction Space requirements. Various analysis methods exist in the present literature, which try to evaluate Construction Space Requirements. However, the AEC community has yet to fully adopt these methods. The proposed modelling methodology attempts to quantify conflict and congestion from a semantic analysis of the two effects, leading to the introduction of a Utilization Factor. A Dynamic Space Interference indicator is also developed based upon the considerations of spatial and temporal interferences, as well as the Utilization Factor. It is intended to be used as an index for decision making regarding project activity scheduling. Finally, a case study involving the refurbishment of an oil refinery column is used to illustrate the application and analysis of the proposed methodology on the planning process in a construction project for improving its constructability. © 2007 Civil-Comp Press.
