Analysis of Problems and Solutions for Delays in Construction Projects A Case Study of the High-Speed Railway Construction Project, Phase 1, Bangkok–Nakhon Ratchasima Section

Abstract

On July 11, 2017, the Cabinet approved the implementation of the High-Speed Rail Regional Connectivity Project, focusing on Phase 1 of the Bangkok–Nakhon Ratchasima section. As a large-scale national infrastructure project with a substantial construction budget, its success carries significant implications. Currently, delays have occurred in the construction phase, particularly in the substructure works for track installation. This study aims to investigate the factors and causes contributing to these delays and propose feasible approaches to improving construction processes to enhance quality control and reduce the likelihood of delays in similar future projects. This research uses a survey-based methodology, using questionnaires to gather data from a sample group. The study focuses on identifying the components and ranking the factors causing delays within the project. The data is derived from the perspectives of three key stakeholder groups directly involved in the project: project managers, construction contractors, and supervising engineers. The collected data is analyzed using Analysis of Variance (ANOVA) to identify the causes of delays from multiple viewpoints. The findings aim to provide actionable insights and recommendations for mitigating delays and enhancing the efficiency of construction project management
