This research examines how construction project managers in China integrate sustainability into their decision-making processes despite other constraints, such as cost, time, and quality. Using a Q-methodology, the study reveals a variety of managers' perspectives and strategies on sustainability, highlighting the complexity of integrating sustainability into construction project management.

The study identified three main perspectives of construction project managers: Cost and Sustainability, People and Sustainability, Cost and Quality. The study found that in current practice there is a general preference for safety over sustainability, while there are different perspectives on the sustainability compatibility with project objectives. The study highlights the need for continuous innovation and adaptation in incorporating sustainability while recognizing the diversity of management approaches and the multifaceted nature of construction projects.

While providing practical insights for industry practitioners, the study also recognizes limitations due to data subjectivity, regional differences, and changing external conditions. It is recommended that future research be conducted to compare sustainability integration in different countries and to explore the impact of cultural, economic, regulatory, and environmental factors on sustainable construction practices.
