Modelling the Construction Projects Implementation Barriers: A Structure Equation Modelling Approach

The construction industry significantly impacts the environment and uses natural resources that negatively impact the built environment. Conversely, green buildings can lead to several environmental, social, and economic benefits. The paper explores the barriers that impede the implementation of sustainable construction projects in Iraq. It draws on a literature review in the field of sustainable construction, as well as a survey of construction industry professionals in Iraq. A total of 17 major barriers to sustainable construction projects are identified and classified into four groups to reduce the environmental impacts of construction activities. The variance inflation factor (VIF) values of dimensions were less than 3.5, indicating that they independently contribute to the second-order constructs. Therefore, it is essential to implement green building practices, such as using energy-efficient materials and systems, adopting energy-efficient designs, and using renewable energy sources. Furthermore, the findings suggest that sustainable construction practices can also help improve quality of life.
