Enhancing Sustainability in Project Management through Smart Technology Integration: A Case Study Approach to Green Building Projects

The combination of smart technologies, such as the Internet of Things (IoT) and Building Information Modelling (BIM), however, has become the disruptive approach to improve sustainability in project management, particularly in green construction projects. The objective of this study is to assess the effect of these technologies upon sustainability end points, specifically toward outcomes, including energy efficiency betterment, cost/waste reduction, and optimization of resources use. Based on the Resource-Based View (RBV) and Stakeholder Theory, the current study, for the first time, offers, a theoretical structure to explain how smart technologies relate to sustainability goals. Employing a mixed-method design, the present study obtained quantitative data with standardized questionnaires and qualitative data through semi-structured interviews. SPSS Statistics quantified the outcomes while qualitative data were coded with NVivo to establish relevant themes, for example energy efficiency and stakeholder satisfaction. Results show that IoT-based systems and BIM has a notable effect on project sustainability by providing real-time data for decision making, decreasing operational defaults, reduced environmental impact. This study makes a contribution to the sustainable management of the project literature by presenting the economic and environmental advantages of smart technologies. It also offers practical recommendations--e.g., policy frameworks and capacity-building programs--to facilitate the meta-scale introduction of these technologies. These observations are of great use to those working in the industry, the policy makers and researchers who are contributing to the development of sustainability in the construction industry.
