IMPLEMENTATION OF GREEN CONSTRUCTION TECHNOLOGIES AND PROJECT SUSTAINABILITY PERFORMANCE: THE MODERATING ROLE OF REGULATORY ENFORCEMENT IN THE PAKISTANI CONSTRUCTION INDUSTRY

Abstract

The construction industry is a major contributor to environmental degradation, necessitating the adoption of sustainable practices such as green construction technologies (GCTs). This study examined the impact of GCT implementation on project sustainability performance (PSP) in the Pakistani construction industry, with a particular focus on the moderating role of regulatory enforcement. A quantitative research design was employed, and data were collected from 278 construction professionals using a structured questionnaire. The data were analyzed using Structural Equation Modeling (SEM) to test the proposed relationships. The findings revealed that green construction technologies have a significant positive effect on project sustainability performance, indicating that the adoption of environmentally friendly materials, energy-efficient systems, and digital tools enhances environmental, economic, and social outcomes. Regulatory enforcement was also found to have a direct positive impact on sustainability performance. Furthermore, the study confirmed that regulatory enforcement significantly moderates the relationship between GCTs and PSP, such that the positive effect of green technologies is stronger under conditions of strict enforcement.

The study concludes that the successful achievement of sustainability in construction projects requires not only the adoption of green technologies but also strong regulatory frameworks to ensure their effective implementation. The findings provide valuable insights for policymakers, industry practitioners, and researchers, highlighting the importance of integrating technological and institutional approaches to promote sustainable construction practices in developing economies.
