Application of multi-criteria analysis in the selection of formwork material for high-rise building construction projects

Selecting an appropriate formwork system becomes complex as one must take into account various factors and their impacts in order to make informed decisions tailored to each specific project. Thirty-three influencing factors were identified specifically for consideration when choosing the formwork in the Vietnamese context. After analysing data collected through a survey with these persons working in the construction field, the study has identified primary groups by using Exploratory Factor Analysis (EFA). Next, the study creates an Analytic Hierarchy Process (AHP) to compare the alternatives for selecting formwork within the scope of considering the evaluation criteria discovered from the previous factor analysis step. The results of this investigation clarify the primary determinants influencing the choice of formwork systems and concurrently pinpoint the optimal alternative via the formulated model. Additionally, the outcomes of this study aim to enhance managerial awareness concerning formwork techniques and promote the widespread utilization of decision support tools in high-rise construction projects. This initiative has the potential to improve the accuracy of planning operations and enhance the success of construction projects.
