Abstract

In this paper, the evaluation of Fly Over ^X^ foundations will be discussed based on analytical and dynamic loading test whether the foundation meets safety criteria or not, and the strengthening of foundation are proposed in this paper. During the construction of Fly Over ^X^ substructure, it was found that the result of loading test of bore pile foundation in Pier 5 and Pier 18 did not meet the minimum requirements and specification. The loading test was carried out using Pile Driving Analyzer or PDA resulting in the ultimate bearing capacity of Pier 5 and Pier 18 foundation each are 397 Ton and 515 Ton, while the bearing capacity criteria need to meet is 675 Ton. In this paper, analytical and loading test evaluation of Fly Over ^X^ foundation is presented to determine whether the foundations are able to withstand external loads according to Indonesian Standard. Standard penetration test result also used to determine the allowable bearing capacity and total settlement of foundations. Based on the evaluation result, the foundation at Pier 5 and Pier 18 needs to be strengthened by adding each 12 piles and 16 piles surrounding the existing pile configuration so that the substructure can meet the safety criteria. The placement and construction method of new piles must consider the land availability, traffic management, and bridge clearance.
