Based on the analysis of calculation results from the Reese & Wright method for a foundation with a diameter of 80 cm at a depth of 2 m is 19.81 tons, a depth of 12 m is 329.29 tons, a depth of 20 m is 76.92 tons, a depth of 25 m is 98.37 tons. While the calculation result of the Reese & O’Neil method at a depth of 2 m are 106.15 tons, a depth of 12 m is 109.76 tons, a depth of 20 m is 110.16 tons, a depth of 25 m is 109.59 tons. The calculation results of the Mayerhoff method a diameter of 80 cm based on N-SPT at a depth of 2 m is 125.51 tons, a depth of 12 m is 137.68 tons, a depth of 20 m is 158.17 tons, and a depth of 25 m is 161.38 tons. The results of the calculation of the settlement of the foundation with the Vesic method is 1.2 cm and the allowable settlement is 0.8 m

The Bojong Apus suspension bridge was built to facilitate access for the people of Bojong Apus Village to Pariuk Kedung Lebak Village in Kalanganyar District, Lebak Regency. The bridge was damaged and its upper structure tilted due to being unable to withstand the current of the Ciujung river. Therefore, the local government repaired the bridge as community access and an alternative route. The aim of this research is to determine the bearing capacity a settlement of the bored pile foundation. The method for calculating carrying capacity based on the N-SPT value is using the Reese & Wright, Reese & O’Neill, and Mayerhoff methods. For the reduction method, use the Vesic method with a diameter of 80 cm.
