Abstract

The construction of the Probolinggo–Banyuwangi Section 3 toll road requires an in-depth analysis of the impact of soil site class on bridge construction costs. This study aims to evaluate the relationship between soil site class and bridge construction costs using a quantitative approach with a comparative analysis method. Data were obtained through geotechnical investigations and borehole analysis using N-SPT values. The results indicate changes in soil site class at several locations, such as Pier 1, which shifted from medium to soft soil. This impacted the need for redesigning foundations and increased implementation costs by up to 345.40%. These findings highlight the importance of evaluating soil site class in infrastructure planning to optimize structural stability and cost efficiency.
