<p align="justify">Balikpapan Football Stadium is located at Jalan Mulawarman, Manggar, East Balikpapan, Balikpapan City, East Kalimantan. The stadium is planned to have a building measuring 205 m x 166 m located on an area of 585 m x 355 m. This area is located 20 km from the city center. The stadium consists of 4 floors included ground floor, second floor, third floor and fourth floor. The stadium has a capacity of 36000 spectators. Alignment of the Balikpapan Football Stadium area requires excavation and embankment work to achieve a 2% slope of the plan. The stadium building will stand on flat ground at + 5m elevation. For this land flattening there will be a slope of 3.5% in the northern area of the stadium building. Slope stability analysis is performed to ensure that the slope safety factor is not less than 1.5. Analysis of slope was done to determine the large decrease in consolidation and the decrease of time that occurred. Slope stability analysis is done with GeoSlope program, while the embankment analysis is done by manual calculation. The calculation of excavation volume and embankment is done with the help of AutoCAD program. Determination of soil data is done by field test that is 2 SPT test point (Standard Penetration Test) and laboratory test. The stadium building will be built on perforated ground and sand with soft to medium soil conditions. Hard soil at a depth of 8 m foundation to be able to withstand the load from the upper structure. Used piles with 2 types of diameter used, ie 0.4 m and 0.8 m diameter. There are 8 types of group foundation with varying pile lengths. The pile group foundation which is a pile cap contains 4 piles with the same diameter and depth of pile for one pile cap. Planning of the pile foundation that is done is checking the axial carrying capacity with a frequency of 2.5 and checking the lateral bearing capacity of the pile foundation using LPile program. Counting pole groups is calculated using the Vesic method, while the lateral pile foundation deformation calculates using the ENSOFT Group program. Planning of pile foundation and its supporting elements, such as pile cap and tie beam. Planning of support elements is done by manual calculation and PCACOL. <p align="justify">
