<![CDATA[Gedebage District, Bandung City, is predominantly underlain by highly plastic soft clay, which may cause stability and deformation issues during excavation works. This study evaluates a basement excavation supported by a secant pile wall system and analyzes the influence of construction methods on lateral wall deformation and excavation stability. Numerical modeling was performed using the Finite Element Method with the Hardening Soil model. Soil parameters were determined from CPTu data and correlations from relevant literature due to limited site data. The construction methods examined include strutting, open cut, and temporary berm under undrained and drained conditions. The evaluation was based on a maximum lateral deformation limit of 1%H and a minimum Factor of Safety of 1.5 in accordance with SNI 8460:2017. The results indicate that strutting is the safest and most effective method for controlling deformation and maintaining excavation stability at the study site.]]>
