Soil Investigation for the Solo Balapan–Kadipiro Elevated Railway Line – KM 106+900 to KM 107+914

The Soil Investigation for the Solo Balapan–Kadipiro Elevated Railway Line, from KM 106+900 to KM 107+914, was conducted to obtain geotechnical data and soil condition information as a basis for the design and construction of elevated railway infrastructure within an urban environment. The scope of work included field geotechnical investigations, soil boring and testing, soil sampling, and evaluation of soil stratigraphy and geotechnical parameters for the design of foundations and elevated railway structures. Key challenges included varying subgrade conditions, foundation stability under dynamic railway loading, and the need for detailed geotechnical data to support the safety and long-term serviceability of the elevated railway infrastructure. The technical approach involved systematic geotechnical investigation and testing, evaluation of soil characteristics and foundation bearing capacity, and development of technical recommendations to support the safe, stable, and reliable construction of the elevated railway line.
