Modular construction involves manufacturing building units in a factory before assembling them on site, offering a more sustainable approach to building. While common in developed regions, adoption remains low across developing nations. Research surveying construction professionals in Egypt evaluated the critical success factors and enablers influencing the uptake of modular methods in housing developments. By using partial least squares structural equation modelling, the analysis measured the relationships between these success factors and actual adoption. The results demonstrate that critical success factors exert a significant, moderate influence, accounting for 62.1 percent of modular construction adoption. These findings establish a structured roadmap designed to guide housing stakeholders and policymakers seeking to integrate offsite manufacturing methods into upcoming residential building schemes.
Residential building in developing economies requires sustainable and efficient delivery methods. Modular construction provides an offsite alternative that reduces environmental impacts, yet industry uptake remains sluggish. Demonstrating how specific critical success factors drive adoption gives industry leaders and public authorities clear evidence to plan policy reforms, adjust procurement approaches, and accelerate modern building practices across the housing sector.
This research provides an applied decision framework for housing developers, contractors, and public policymakers in developing economies such as Egypt. The model is at an applied research stage, validated through survey data rather than deployed in live procurement systems. Construction firms and housing agencies can use the roadmap to target specific operational enablers, lower implementation risks, and prepare supply chains for prefabricated residential housing projects.

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.
