Abstract
Modular construction (MC) is considered a greener and more sustainable construction and is obligatory for measuring the project's sustainability. MC is a building process in which modules are fabricated in a factory and then installed onsite. Although MC is popular in developed countries, its uses are still very limited in developing countries. This study aims to introduce a model to promote the adoption of MC by analysing the relationship between critical success factors (CSFs) and their enablers, as well as modular construction adoption (MCA), for housing projects in developing countries to reach the MC benefits. This aim is accomplished through three main phases. The first phase is the exploratory phase that used to determines MC's CSFs, enablers, and benefits through a comprehensive literature review. The second phase is the descriptive-explanatory phase, which used a questionnaire survey strategy to evaluate the significance of these CSFs and their enablers. The questionnaire survey was conducted with building specialists in the Egyptian construction industry. The third phase is the structural equation modelling (SEM) phase using partial least square (PLS) method that used to test the correlations between the CSFs and MCA using the measurement and structural models. The findings pointed out that the CSFs significantly impacted the MCA by 62.1%, which considered a moderate effect. The contribution of the study provides policymakers and other project stakeholders with a roadmap for implementing MC in developing countries, including Egypt and the support needed to focus on the benefits of MCA that could take place in their current or future projects.
