Overall Barriers to The Prefabricated Construction Industry: A Fuzzy-SEM

Abstract

Prefabrication construction (PC) is a greener and more sustainable building method that must be used to achieve the project's sustainability. PC is a construction method in which modules are manufactured in a factory and then placed on-site. Although PC is widely used in developed nations, its applications in developing countries remain extremely limited. The primary objective of this investigation is to analyze and introduce a model for the fundamental factors that impede the implementation of prefabrication in the construction sector of Egypt. In order to attain the desired objective, a comprehensive literature review, expert consultations, and face-to-face interviews were conducted to gather 23 observable variables that significantly influence the prefabrication construction industry. A questionnaire form was developed and distributed among professionals in the construction field, and a total of 371 replies were gathered during the collection of data. Following that, fuzzy theory was utilized for analyzing the probability and impact data from the questionnaire survey to determine the risk relevance for each factor. Then, a model consisting of 15 variables and five major latent dimensions was produced. A proposed SEM model was developed in the next phase using the measurement and the structural model. The findings indicate that the policy factor and attitudinal factors have a predominant influence. The current study provides meaningful data about the aspects covered, which can help in the development of effective strategies for promoting prefabricated construction.
