| Abstract | ||||
| Sustainability has emerged as a central consideration in modern construction engineering, particularly in large-scale infrastructure projects such as highways. This study focuses on identifying and analyzing the critical factors that influence the sustainability of highway construction projects from a construction engineering perspective. The research utilizes the Analytic Hierarchy Process (AHP), a structured multi-criteria decision-making technique, to assess the relative importance of grouped sustainability indicators in relation to project owner priorities. These include technical performance, construction duration, quality standards, and constructability. The analysis is structured around the three core pillars of sustainability—environmental, economic, and social and integrates them with engineering-focused evaluation criteria. The findings reveal that specific factors such as Energy use noise emissions during construction, long-term maintenance costs, and the degree of social integration have significant implications for sustainable construction outcomes. These factors not only affect the environmental footprint of highway projects but also influence cost efficiency, operational resilience, and social acceptance throughout the project life cycle. Based on the results, the study presents a set of engineering-oriented recommendations to enhance sustainability performance. These include adopting environmentally sensitive construction techniques, optimizing resource use and life cycle costs, engaging relevant stakeholders early in the planning and design phases, and implementing integrated project delivery (IPD) and sustainable construction management practices. By integrating these recommendations, highway construction projects can achieve a more balanced and sustainable performance across technical, environmental, and social dimensions, thereby aligning with national and international sustainable infrastructure goals. | ||||
