ANALYSIS OF FACTORS AFFECTING THE PROGRESS OF CONSTRUCTION PROJECT IN VIET NAM

Abstract

In construction projects, three core objectives, including quality, cost, and schedule, are considered key criteria for project success. However, in Vietnam, project delays remain prevalent, significantly affecting investment efficiency and construction quality. This study aims to analyze the factors affecting construction project schedules and to evaluate the impact of delays on project cost and quality. The research methodology involves a synthesis of domestic and international studies, combined with surveys of experts and experienced professionals in the construction field. Data were collected from 173 valid responses and analyzed using statistical techniques, including Cronbach’s Alpha, Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), and Structural Equation Modeling (SEM). The results indicate that the measurement scales are reliable and valid, with statistically significant observed variables and a well-fitted research model. The findings reveal that contractor-related factors have the greatest impact on project schedules, followed by factors related to equipment and materials; project owners and project characteristics; design units; external factors; and consulting units. Notably, the “decision-making speed of the project owner” is identified as the most influential factor. The SEM results demonstrate that project delays have direct effects on cost (coefficient = 0.41) and quality (coefficient = 0.38). This study provides empirical evidence on the relationships among schedule, cost, and quality, while supporting stakeholders in identifying and managing risk factors. Accordingly, the findings contribute to a scientific basis for improving schedule management efficiency and enhancing the success rate of construction projects in Vietnam.
