Determinants of sustainable construction practices in Ghana using structural equation modelling

Abstract

Today's world is faced with a wide range of threats to the environment as well as the socioeconomic development. Construction industry has a role to play in ensuring a healthy-livable environment and equitable access to social infrastructure in developing countries. The purpose of the study is to examine the adoption of Sustainable Construction Practices (SCP) in the Ghanaian Construction Industry (GCI). The study adopted a quantitative research design involving structured questionnaire developed to collect data. Data was analyzed using descriptive statistics and Structural Equation Modeling (SEM) via Partial Least Squares (PLS). Two models were developed in the study: a direct model and an in direct model. The direct model findings suggest that four independent variables had a significant influence on adoption namely; compatibility (COM), knowledge (KNW), peer firm influence (PEER) and trialability (TRA) supported adoption while three independent variables namely; complexity(CPX), observability (OBS)and Relative advantage (RAV) did not. Based on the findings of the study, the study made recommendations which, if adopted, could lead to significant improvement in the adoption rate of SCP in Ghana.
