KEY SUCCESS FACTORS FOR THE CONSTRUCTION PROJECT OF MASS RAPID TRANSIT IN HEAVY RAIL TYPE

The construction project of mass rapid transit in heavy rail type is an infrastructure endeavor with high complexity and substantial budget allocation. It involves coordination among various stakeholders and demands consideration of numerous factors for project success. This research aims to explore the success factors in mass rapid transit construction projects and compare them under two contract models: Design-Build and Design-Bid-Build (or Detailed Design). This qualitative research gathered data through interviews with 13 project owners. The quality of research tool has been assessed before data collection. And the research also assessed data saturation through triangulation methods to ensure accuracy and alignment with the research objectives. The research found that the success factors for construction projects of mass rapid transit in heavy rail type consist of a total of 45 factors. Importantly, these factors manifest at different stages throughout the project life cycle. Finally, the comparative analysis of the Design-Build and Design-Bid-Build contract models revealed no significant differences in the majority of factors contributing to the success of construction project of mass rapid transit in heavy rail type.
