Students would like to thank all of them for their valuable help.
The student would also want to express their deepest appreciation to Dr. Do Tien Sy and Dr. Nguyen Thanh Viet, who supported and assisted them during the completion of this thesis. In addition, the student would like to express their appreciation to the faculty and friends of University of Technology VNU - HCM for their assistance in the past.
The master's thesis has been completed, but there are shortcomings. Dear teachers, please show that the candidate can learn more and get better. Sincerely, HCM city, date month year 2022 Truong Thanh Tung iii ABSTRACT The construction field in Vietnam is currently one of the country's most vital economic drivers. The rapid emergence of new urban projects necessitates the conduct of research to identify and address the challenges posed by new urban development.
Evidence shows that stakeholders in urban projects still do not know about the claim causes that affect the cost and schedule of urban projects. Ho Chi Minh City is the primary focus of this study. The study presents the results of an investigation into claim causes that affect schedules and costs in Vietnam's new urban. Identify and rank, through survey questionnaires and statistical analysis, the claims caused by the cost and schedule of urban construction projects.
By the method of exploratory factor analysis (EFA), the study pointed out five main groups of causes affecting the cost and schedule of urban projects, such as "Contractor's lack of experience and competence; Uncontrollable objective and contractual problems; Inappropriate actions of the owner; Incompetent subcontractors and suppliers; Design problems." In addition, the study describes the characteristics of stakeholder performance when participating in urban projects. Using the SEM model to examine the correlation between groups of factors, then can determine their relationship. Specifically, the group of factors "Contractor's lack of experience and competence" has a significant impact on the factors "Stakeholders' expectations regarding business performance" and "Stakeholders' expectations regarding project performance." The group factor "Contractor's lack of experience and competence" has the strongest influence on the research results. The written proposes several measures for this group of factors to contribute to the minimization of the claim causes affecting the costs and schedules of urban projects, leading to profits, and success.
iv TÓM TẮT Tại thời điểm hiện tại, ngành xây dựng Việt Nam là một trong những ngành mũi nhọn kinh tế quan trọng nhất của đất nước. Sự xuất hiện của các khu đô thị mới với tốc độ ngày càng gia tăng khiến cho việc nghiên cứu bắt buộc phải được tiến hành để xác định và giải quyết những thách thức do phát Đô thị mới gây ra. Bằng chứng cho thấy rằng một số lượng lớn các bên liên quan đang làm việc trong dự án khu đô thị vẫn chưa nhận thức được các sự ảnh của nguyên nhân gây bồi thưởng đến chi phí và tiến độ của các dự án xây dựng đô thị. Thành phố Hồ Chí Minh là khu vực chính của cuộc khảo sát này.
Nghiên cứu trình bày kết quả cuộc khảo sát về các nguyên nhân gây bồi thường ảnh hưởng đến tiến độ và chi phí ở các khu đô thị mới ở Việt Nam. Thông qua bảng câu hỏi khảo sát và phân tích sô liệu thống kê để xác định và xếp hạng các các nguyên nhân bồi thường ảnh hưởng đến chi phí và tiến độ cho dự án khu đô thị. Bằng phương pháp phân tích yếu tố khám phá (EFA) nghiên cứu chỉ ra năm nhóm nguyên nhân chính gây ảnh hưởng đến chi phí và tiến độ cho dự án khu đô thị như “Nhà thầu thiếu năng lực và kinh nghiệm, Không kiểm soát được các vấn để khách quan và hợp đồng, Hành động không phù hợp của chủ đầu tư, Nhà thầu phụ và nhà cung cấp thiếu năng lực, Vấn đề thiết kế”. Nghiên cứu cũng đưa ra các tiêu chí đánh giá cho hiệu quả thực hiện các bên liên quan khi tham gia vào dự án khu đô thị.
Bằng mô hình tuyến tính SEM để phân tích mối tương quan để thấy sự tương tác lẫn nhau giữa các nhóm nhân tố. Trong đó, nhóm nhân tố “Nhà thầu thiếu năng lực và kinh nghiệm” có tác động mạnh đến nhân tố “Mong muốn của các bên liên quan về hiệu quả kinh doanh” và “Mong muốn các bên liên quan về hiệu suất thực hiện dự án”. Nhóm nhân tố “Nhà thầu thiếu năng lực và kinh nghiệm” có ảnh hưởng mạnh nhất qua kết quả nghiên cứu. Tác giả đề xuất một số biện pháp cho nhóm nhân tố này, nhằm góp phần giảm thiểu các nguyên nhân gây bồi thường ảnh hưởng đến chi phí và tiến độ cho dự án khu đô thị, khi, nhằm đem lại lợi nhuận và thành công cho dự án.
