In the course of the development of the world of civil construction, soil is a building material that can function as the foundation of a building structure. Clay soil is a type of soft soil with fine grain characteristics. The soil has a shrinkage property where when exposed to water it will expand according to the amount of water absorbed, but when it is dry it will shrink to its original dimensions with non-directional compaction. The consistency of clay soil does not support the safety of the building it supports. In constructing a construction, it is necessary to plan a sturdy and strong soil structure to prevent slip failure (clayey & longitudinal). The soil that often experiences problems in the construction of civil construction is clay. Therefore, a Direct Shear test was carried out at the Kadiri University Civil Engineering Laboratory. The results of this study obtained the value of the soil shear strength parameters. The direct shear strength test aims to determine the feasibility of the soil to accept construction loads, obtain parameters of the shear strength of disturbed soil or unconsolidated and undisturbed undisturbed soil. The shear strength test of the soil is carried out to determine the strength of the soil against the displacement that occurs in the soil. Based on the results of the direct shear strength test, the cohesion value was 0.330 and the shear angle value was 2.929. This value indicates that this soil is unstable, prone to landslides and is not feasible to carry construction loads

Soil conditions have an important influence on foundation planning in shophouse construction. Sandy soil with a high groundwater table is a problem because it has a low bearing capacity and is difficult for foundation casting. The aim of the research is to plan a proper foundation. This research by taking samples for testing compaction and shear strength. The test results are used to analyze the existing foundation planning. If the bearing capacity value does not meet the load assumption of 100 t/m2, then a re-planning is carried out with a minipile well foundation. The results of the research show that the existing foundation is a palm type foundation and the bearing capacity value is not fulfilled. So that the modification of the well foundation in the form of a minipile was carried out and the soil carrying capacity was obtained at 36.61 t/m2. To be able to withstand the load of the structure, it is necessary to plan the use of 3 minipiles, so that a value of 109.82 t/m2 is obtained which indicates the foundation is suitable for use. The results of this study can be used as a reference for planning foundations with sandy soil conditions with a high water table.
