Abstract

Road subgrade performance is strongly influenced by moisture conditions because changes in water content can alter soil density, strength, and bearing capacity. This study investigated the effect of moisture conditions on the California Bearing Ratio (CBR) of subgrade soil collected from a road settlement area in Dopang Village, Gunungsari District, West Lombok Regency, Indonesia. A laboratory experimental method was employed, including natural moisture content, specific gravity, particle-size distribution, Atterberg limits, Standard Proctor compaction, and CBR testing under unsoaked and 96-hour soaked conditions. The soil had a natural moisture content of 38.90%, specific gravity of 2.70, 26.30% material passing the No. 200 sieve, liquid limit of 31.41%, plastic limit of 21.81%, and plasticity index of 9.60%. The Standard Proctor test produced an optimum moisture content of 18.33% and a maximum dry density of 1.365 g/cm³. The CBR value decreased from 8.142% in the unsoaked condition to 3.392% after soaking, representing a reduction of approximately 58.3%. The results demonstrate that water saturation substantially reduces subgrade bearing capacity. The findings indicate that moisture control, adequate drainage, and appropriate subgrade improvement are essential for reducing the risk of recurrent road settlement at the study location.

Abstract

Building Information Modeling (BIM) has increasingly been adopted in government building projects to improve coordination, design accuracy, and structural analysis. However, the integrated application of BIM for both superstructure and substructure evaluation of high-rise government residential buildings remains insufficiently documented. This study evaluates Building A of the Ministry of Finance's State Flats in Jakarta using an integrated BIM-based structural analysis workflow. A case-study approach was employed using Autodesk Revit 2025 for three-dimensional structural modeling, Autodesk Robot Structural Analysis Professional 2025 for static and dynamic structural analysis, and MIDAS GTS NX for foundation and settlement analysis. Structural loading and seismic performance were evaluated according to applicable Indonesian standards. The results showed that the structural model achieved mass participation exceeding 90% in the principal directions, with 97.7% in the X-direction and 99.22% in the Y-direction. The maximum inter-story drift was 35.82 mm, which was below the allowable limit of 108 mm. The special moment-resisting frame also satisfied the minimum contribution requirement within the dual structural system. The 500 mm diameter driven-pile foundation provided adequate axial and lateral capacity, while the maximum long-term settlement was 3 cm, below the allowable limit of 3.5 cm. The integrated BIM workflow successfully supported structural and geotechnical evaluation and provides a replicable approach for BIM-based analysis of high-rise government buildings.
