Ground improvement involves removing underground moisture from soft ground and hardening the ground using
          various compaction methods. Before full-scale construction, a pilot project was conducted to evaluate methods,
          leading to the application of techniques such as sand drains (SD), prefabricated vertical drains (PBD), and

          preloading (PL). The site preparation work, which began in November 1992, was carried out in a total of 11 zones,
          and site preparation for Phase 1 was completed at the end of May 2000.
