Identifying and assessing modular construction implementation barriers in developing nations for sustainable building development

Abstract

AbstractThe construction sector is one of the largest sectors globally, and it significantly affects countries' economies. Modular construction (MC) is a building process in which modules are fabricated in a factory and then installed on‐site. MC is becoming an integral aspect of the construction sector in developed countries due to its notable benefits in improving sustainability and sustainable development. However, there are various barriers that might decrease MC adoption. This study aims to develop an MC adoption model by investigating the relationship between overcoming MC adoption barriers (MCABs) and overall sustainable success (OSS) for residential projects in developing countries. To accomplish this, 120 Egyptian building professionals responded to the conducted questionnaire. Subsequently, partial least square structural equation modelling (PLS‐SEM) was used to determine the barriers and examine the relationships between overcoming MCABs and OSS. The results showed a moderate association, with overcoming the MCABs contributing 44.7% to the OSS of the residential projects. Moreover, the correlation between overcoming MCABs and OSS is substantial, as demonstrated by the β value path coefficient, which equals .669. The findings can be used as a benchmark for decision‐makers to explore the main barriers to adopting MC in developing countries and achieving OSS in their residential projects.
