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.
