Abstract
Conventional construction methods have drawbacks such as excessive resource consumption, labour-intensive work, and significant contributions to solid waste and gas emissions. Prefabricated construction, on the other hand, has advantages in terms of quality control, speed, economics, flexibility, safety, and sustainability. This study aims to identify and highlight the primary obstacles currently impeding the use of Prefabricated construction (PC) and to promote PC’s widespread use. By defining the current barriers in Egypt using the appropriate literature re-view and Delphi technique, evaluating the probability and impact of each barrier using fuzzy set theory, and analyzing the weighted relationships between them using the path coefficient of the latent variables influencing PC promotion, this thesis fills a knowledge gap. In-person inter-views and expert consultations were used to determine the 20 observable factors that have a major impact on the prefabricated building sector. Subsequently, a five-point Likert scale was used to develop a questionnaire form, and 371 responses were gathered through face to face interviews and online surveys. The probability and impact data from the questionnaire survey were then subjected to fuzzy theory analysis in order to transform the qualitative data into quantitative crisp values that represent the importance for each barrier. The crisp values were then input into SEM. A detailed review of pertinent literature and consultation with experts led to the identification of a model with five latent dimensions. The proposed model was then examined using SEM with measurement and the structural model, and two case studies were used to validate it. In the results the latent variables were ranked from the most critical to the least critical as follows: External barriers, Design barriers, construction barriers, management barriers, and industry barriers with standardized estimates of 0.81, 0.77, 0.70, 0.69, and 0.66, respectively. In order to effectively build strategies for promoting prefabricated construction, it is helpful to precisely define the obstacles that project teams may encounter when attempting to employ PC as a construction strategy. This has been made achievable by the proposed SEM model. The results of this study should be helpful to policy makers, academics, practitioners in the building industry, local and national governments, and all individuals involved in managing a sustainable Egyptian construction sector.
