Abstract—In Indian construction industry, decision regarding formwork selection is primarily based on the intuitive and subjective judgments of formwork experts. With an objective to rationalize the process of horizontal formwork selection, the research identifies from literature eighteen attributes affecting selection of horizontal formwork. These attributes were then statistically analyzed to yield six formwork selection factors, namely: building design and architectural features; job specifications and conditions; local conditions; quantity of formwork; available capital and site characteristics, and organizational support. Further, analysis of the extracted factors using Analytical Hierarchy Process (AHP) revealed that the most dominant factor that governs the choice of formwork system for any construction project is ‘available capital and site characteristics’. However, to ensure an optimal selection, all the factors should be considered judicially. Furthermore, the research develops a quantitative Decision Support Model (DSM) for horizontal formwork systems. Performance analysis of the model through case studies revealed that the developed model offers more than 80% accuracy.
