In the construction process, buildings require careful planning because structural elements must withstand axial loads, such as gravitational forces, and lateral loads, such as wind and earthquake forces, which are transferred to the foundation. One key aspect of foundation design is determining its bearing capacity. This capacity can be calculated theoretically using soil investigation data, while the Pile Driving Analyzer (PDA) verifies these results. This study aims to calculate and analyze foundation bearing capacity and compare it with PDA results. The Schmertmann & Nottingham and Meyerhoff methods were used. Using the Schmertmann & Nottingham method, the carrying capacities based on sondir test results were: S1—804.15 tons, S2—761.99 tons, S3—823.45 tons, and S4—841.68 tons. Using the Meyerhoff method, the values were: S1—572.39 tons, S2—568.93 tons, S3—568.84 tons, and S4—562.4 tons. The highest ultimate bearing capacity (Qu) was from the Schmertmann & Nottingham method at S4, while the lowest was from the Meyerhoff method at S4. The Meyerhoff method at S4 and the BP-109 PDA showed the closest results, differing by 115.5 tons, whereas the Schmertmann & Nottingham method yielded significantly greater values than the PDA.
