Construction starts with earth work that takes a long time. To reducing these problems, acceleration is usually done on the site. For example, doing basement excavations at same time with driven piling. Early basement excavation work has the potential to cause the foundation piles that has been driven will be slided. Besides being supported by expansive soil, use of diesel hammer which has large blow energy as driven machine will also affect additional lateral load on the ground which causes pile or wall to slide or roll. In this study, the calculation of additional loads due to piling and soil using Boussinesq and Rankine Theory. The Reese and Matlock Method is used to calculate the lateral deflection of the pile. Pile will experience lateral deflection 30 mm exceeding the permit tolerance of 25 mm. Earth retaining wall with 3,2 m and 6,4 m excavations, the wall does not slide and roll. On the earth retaining wall with 9,6 m excavations, the wall does not slide but it will be rolled. The conclusion of this study is doing excavation when piling work has not been fully completed, it will potentially causing damage to the construction that has been made.
