The Importance of Foundation Calculation in Building Structures

The foundation is a crucial element in the building structure system, serving as a medium to transfer the burden of the structure into the soil or rock below. This ensures that the building can withstand various loads and prevent excessive settlement that exceeds the allowable limit. The calculation of the carrying capacity of the foundation is, therefore, a vital aspect of building construction, as it directly affects the stability and safety of the structure.

Background of the Study

The Koleza 9 Residence building project, managed by PT. Wilmar in Percut Sei Tuan, Medan, required an analysis of the carrying capacity of the foundation of the 50 cm diameter pile. This study involved data collection from various sources, including Standard Penetration Test (SPT), Sondir, and Loading Test. The methods used to calculate the axial carrying capacity included the Chin method, the Davisson method, and analysis using the element method. Meanwhile, to calculate lateral carrying capacity, the Broms method was employed.

Methods and Results

The study involved the collection of data from various sources, including SPT, Sondir, and Loading Test. The results of the study showed that the calculation of the carrying capacity of the ultimate pole at the Bore Hole 5 point with a depth of 24.54 meters produced different values. The carrying capacity based on SPT reached 265.17 tons, while the data of Sondir was 442.35 tons. The calculation results through the loading test showed that the Chin method gave a value of 333.33 tons, while the Davisson method produced 254.85 tons. In addition, the analysis using the element method showed a carrying capacity of 379.6 tons.

For lateral ultimate carrying capacity, the Broms method gave an analytical value of 18.13 tons and a graphical value of 20.66 tons. In addition, the elastic settlement that occurred on this pile was 10.45 mm, while the result of the loading test method showed a settlement of 9.04 mm.

Discussion and Analysis

It is essential to note that there is a difference between the results of carrying capacity and settlement obtained from different methods. This can be caused by several factors, such as variations in the type of soil in the location, the method of implementing testing that depends on the operator's expertise, as well as the differences in the parameters used in the calculation.

Additional Analysis and Explanation

The analysis of the calculation of the capacity of the carrying capacity of the pile foundation is crucial to ensure the reliability and safety of the building structure. In the context of the Koleza 9 Residence project, this calculation becomes more complex because it involves various factors that affect the carrying capacity. For example, different types of land at the project site can have a significant effect on the calculation results. The more dense and dry soil usually has a higher carrying capacity than soft or runny soil.

In addition, testing techniques also play an important role. Tests carried out incorrectly can result in inaccurate results. Therefore, it is essential to involve experienced experts in conducting this carrying capacity test. The parameters used in calculations must also be adjusted to the actual field conditions so that the results of the calculation are more representative.

Conclusion

The calculation of the carrying capacity of the pile foundation is a critical aspect of building construction, as it directly affects the stability and safety of the structure. The results of this study show that the carrying capacity of the ultimate pole at the Bore Hole 5 point with a depth of 24.54 meters produced different values using various methods. It is essential to note that there is a difference between the results of carrying capacity and settlement obtained from different methods, which can be caused by several factors.

Recommendations

Based on the results of this study, it is recommended that:

Experienced experts should be involved in conducting the carrying capacity test to ensure accurate results.
