A Decision Approach for Analysing the Role of Modern Methods, Project Management and Integrated Approaches in Environmentally Sustainable Construction Projects

Abstract

A global concern for a transition to a sustainable construction approach is imminent and highly important. This research aims to identify a justifiable strategy to improve sustainable construction success. To enhance the success rate of sustainability, important factors contributing to the cause such as project management, integrated approaches, and modern methods of construction (MMC) are studied. The core ideology is to understand the relational attributes of these factors, their significance, and the mediating effect of modern methods of construction (MMC) in sustainable project success. A deductive research approach is undertaken, by performing a web-based self-administered quantitative questionnaire survey with 5-point Likert scale. The survey adopts the snowball purposive sampling technique to collect data from construction professionals like project managers, architects, contractors, researchers, etc. The survey recorded a total of 149 responses, majorly from the UK, forming the base for several statistical data analysis techniques, supporting the formulation of research findings. Structural equation modeling is the cardinal analysis approach carried out to draw relational values between the principal research factors. The findings of the research highlight that both project management and integrated approaches display a significant positive relationship with sustainable construction project success. It is observed that project management and integrated approaches have positive impact on sustainable construction success with R = 0.208 and R = 0.569 respectively, at a significance value <0.05. Moreover, incorporating modern methods of construction as the mediating factor further enhances the project success rate. Thus, it can be depicted that in order to gain a maximum output from project management and integrated approaches to build the sustainable construction the role of modern methods of construction is critical. The research will help to bridge the gap between available extensive knowledge on sustainable construction and scant information on its successful implementation.
