Building information modeling (BIM) is acknowledged for enhancing efficiency and collaboration in the construction industry. However, its application in the construction phase of railway projects faces challenges. This study, utilizing quantitative and qualitative analyses, explores the advantage of BIM consulting services in the railway infrastructure projects. A comparative analysis of similar-scale projects shows that BIM significantly boosts construction efficiency, yielding a 197.6% economic benefit in pilot projects. This study also delves into the BIM application environment in railway construction. Our findings provide valuable insights into BIM’s advantages and challenges, emphasizing the need for further research. The results will contribute to advancing railway infrastructure and promoting BIM’s application, aiding decision makers and practitioners in understanding its potential contributions to a more efficient and sustainable industry.
