Model Development of Constructability

M. Malek


The choice of the construction system is a multivariate decision making with criteria that vary from one project to the other, depending on the particularities and constraints imposed on the builder. This research develops a tool that measures the constructability of various construction projects. The decision making logic is based on fuzzy set theory (FST). FST is used to address uncertainties in decision making. The tool is generic enough to allow the user to encompass the criteria of the project at hand and to select the construction system best suited for its execution. The objective of this research is the development of the decision support model and the demonstration of its use. This research also furnishes an extensive environment for further development. It provides the blueprint to achieve the overall goal of assessing the project constructability and smoothes the path for further refinement of the rules to be used at each step of the overall model. Through this model users are able to predict the feasibility of a project, and determine the most advantageous system to be used for its implementation. An analysis of the model illustrates that the results are accurate and the system demonstrates utility for practical use.
