Soft soils undergo consolidation when subjected to additional loads, owing to their low shear strength and high compressibility. This research conducts a comparative analysis of soil improvement techniques, specifically examining the application of pile raft and pile bent structures, with a focus on safety factors and construction time. The study employs the finite element method, incorporating hardening soil parameters to simulate the soil behavior and embedded beam parameters to model the pile raft and pile bent structures. The analysis adheres to the SNI Geotechnical 8460:2017 standard for assessing geotechnical safety. The findings of this investigation reveal that the utilization of pile bent structures offers greater efficiency in terms of accelerated construction timelines and favorable safety factors when compared to meticulous soil improvement practices. The latter necessitates an extended duration due to the substantial embankment process, often reaching heights of up to 12 meters, while pile bent structures only require a 3-4 meter embankment as a platform, with the remainder of the structure designed to meet the required elevation. This research underscores the advantages of employing pile bent structures in projects involving underconsolidated soil, offering valuable insights for the construction industry and potentially influencing future engineering practices in similar contexts.
