This graduation thesis was completed not only thanks to my own efforts but also with the support of everyone around me.
First of all, I would like to express my deepest and warmest thanks to Assoc. Do Tien Sy and Dr. Nguyen Van Tiep , my two instructors. The wonderful comments, suggestions and connections of the two teachers were extremely helpful to me, not only on the journey of conducting my master's thesis research but also in my future career and life.
Second, I would like to sincerely thank the teachers of Construction Management, Ho Chi Minh City University of Technology for enthusiastically teaching and inspiring me with valuable knowledge during my 2 years of university studies. Furthermore, I would like to express my deep gratitude to my classmates of the International Master's Program – Ho Chi Minh City University of Technology, who have made this program a great success and continuously supported me during the course. I would like to send special thanks to the experts, survey participants, and my colleagues at Bao Ngan Construction Company such as the project management board, IVY contractors, ICIC consultants, and contractors' engineers. During my time as a supervisor in the company, the department spent their valuable time and efforts to support my survey and share with me their best advice.
Finally, I am forever grateful to my family members and friends, who have always been by my side, cared for me, understood me, and given me valuable encouragement during difficult times. Best regards Ho Chi Minh City, May 20, 2024 TRAN LE DUY iii ABSTRACT Purpose: In developing countries, construction organizations are seeking to effectively implement innovation strategies by applying model circular economy practices to the construction sector. Therefore, this study aims to assess the importance of applying circular economy to construction projects and developing a risk assessment model for circular economy practices in construction project. Design/ Methodology/Approach: Apply research methods including: First, an extensive literature review is conducted to identify the items of applying circular economy to real projects, which are then used to design a preliminary questionnaire.
Next, expert interviews are conducted to pilot-test this questionnaire. Subsequently, by using a convenience non-probability sampling method, 145 valid responses are collected from construction companies in Vietnam. Then, one-sample and independent-samples t-tests are employed to assess the importance of applying circular economy activities in the construction sector. Fuzzy Synthetic Evaluation (FSE) is also applied to quantitatively compare such practices.
Finally, a proposal table is developed to measure the indexes of circular economy practices in construction projects. Value: This research is one of the first attempts to integrate circular economy practices into the construction sector in particular and the entire economy in general. The established indexes provide assessments of the risks of circular economy activities in construction projects, which could be considered as valuable references for construction practitioners. Furthermore, the study proposes a reliable and practical tool to measure the level of impact of circular economy practices risks on construction companies in developing countries.
Key Word: Circular economy(CE) practices; Construction project; Construction industry; Developing countries; Fuzzy Synthetic Evaluation (FSE); Paper type: Thesis. iv TÓM TẮT LUẬN VĂN Mục đích: Tại các nước đang phát triển, các tổ chức xây dựng đang tìm cách triển khai hiệu quả các chiến lược đổi mới bằng cách áp dụng mô hình các hoạt động kinh tế tuần hoàn vào lĩnh vực xây dựng. Vì vậy, nghiên cứu này nhằm đánh giá tầm quan trọng của việc áp dụng mô hình các hoạt động kinh tế tuần hoàn vào các dự án xây dựng và xây dựng mô hình đo lường để xác định mức độ đổi mới của các doanh nghiệp xây dựng khi áp dụng các hoạt động kinh tế tuần hoàn vào các dự án thực tế. Thiết kế/Phương pháp/Cách tiếp cận: Áp dụng phương pháp nghiên cứu gồm: Đầu tiên, tiến hành đánh giá tài liệu chuyên sâu để xác định các mục áp dụng kinh tế tuần hoàn vào các dự án thực tế, sau đó sử dụng để thiết kế bảng câu hỏi sơ bộ.
Tiếp theo, tiến hành phỏng vấn chuyên gia để thử nghiệm bảng câu hỏi này. Tiếp đến, sử dụng phương pháp lấy mẫu thuận tiện phi xác suất, thu thập được 145 phản hồi hợp lệ từ các công ty xây dựng tại Việt Nam. Sau đó, sử dụng các bài kiểm tra t một mẫu và mẫu độc lập để đánh giá tầm quan trọng của việc áp dụng các hoạt động kinh tế tuần hoàn trong lĩnh vực xây dựng. Đánh giá tổng hợp mờ (FSE) cũng được áp dụng để so sánh định lượng các hoạt động như vậy.
Cuối cùng, xây dựng bảng đề xuất để đo lường các chỉ số thực hành kinh tế tuần hoàn trong các dự án xây dựng. Giá trị: Nghiên cứu này là một trong những nỗ lực đầu tiên nhằm tích hợp các hoạt động kinh tế tuần hoàn vào ngành xây dựng nói riêng và toàn bộ nền kinh tế nói chung. Các chỉ số đã thiết lập cung cấp đánh giá về rủi ro của các hoạt động kinh tế tuần hoàn trong các dự án xây dựng, có thể được coi là tài liệu tham khảo có giá trị cho những người hành nghề xây dựng. Hơn thế nữa, nghiên cứu đề xuất một công cụ đáng tin cậy và thiết thực để đo lường mức độ tác động của các rủi ro thực hành kinh tế tuần hoàn đối với các công ty xây dựng ở các nước đang phát triển.
Từ khóa: Hoạt động kinh tế tuần hoàn; Dự án xây dựng; Ngành xây dựng; Các nước đang phát triển; Đánh giá tổng hợp mờ. Loại báo cáo: Đồ án tốt nghiệp. v THE COMMITMENT OF AUTHOR The undersigned below: Name : TRAN LE DUY Student ID : 2270791 Place and date of born : TRA VINH, February 27, 1998 Address : Ho Chi Minh City With this declaring that the master thesis entitled “DEVELOPING A RISK ASSESSENT MODEL FOR CIRCULAR ECONOMY PRACTICES IN CONSTRUCTION PROJECT” is done by the author under supervision of the supervisors.
