Bored pile foundation is one of the common choices used to support building structures such as the Mega Kuningan Tower construction project. In this study, variations in the dimensions of bored pile foundations will be investigated to determine their effect on foundation performance and material costs. This study evaluates several variations in bored pile foundation diameter and depth to determine the optimal combination that meets the foundation performance requirements while minimizing material costs. Parameters evaluated include bearing capacity, settlement, and structural integrity. Material cost analysis is performed for each dimension variation. The results of this study are expected to provide a better understanding of how bored pile foundation parameters affect structural performance. This information has the potential to help engineers design more efficient and reliable foundations in a variety of soil and environmental conditions.
