Introduction

The foundation of a building is the backbone that distributes loads to the ground, providing stability and safety to the structure. Among various types of foundations, the pile foundation is a popular choice due to its ability to transfer loads to deeper soil layers. However, determining the carrying capacity of the right piles is crucial to ensure the stability and safety of the building. This case study of the construction of the Torganda Siantar Hotel provides an interesting picture of the analysis of the carrying capacity of the mini pile and the calculation of the decline.

Background of the Study

The Torganda Siantar Hotel construction project required a thorough analysis of the carrying capacity of the mini pile foundation system to ensure the stability and safety of the building. The project involved the construction of a high-rise hotel with a complex design, requiring a robust foundation system to support the loads. The mini pile foundation system was chosen due to its ability to transfer loads to deeper soil layers, but determining the carrying capacity of the right piles was a critical aspect of the project.

Methodology

This study involved various methods of investigation, such as Sondir, Standard Penetration Test (SPT), and observations in the field. The data collected was then analyzed with several calculation methods and computer programs. The aim was to get a comprehensive picture of the carrying capacity of the mini pile and the calculation of the decline.

Data Investigation and Analysis Methods

The study involved the following data investigation and analysis methods:

Sondir: A non-invasive testing method used to determine the soil density and bearing capacity.
Standard Penetration Test (SPT): A testing method used to determine the soil density and bearing capacity.
Observations in the field: Field observations were made to determine the soil conditions and the behavior of the mini piles.

Calculation Methods

The study involved the following calculation methods:

Load transfer method: A method used to calculate the carrying capacity of the mini pile.
Computer programs: Computer programs were used to analyze the data and calculate the carrying capacity of the mini pile.

Results and Discussion

The results of the calculation of the carrying capacity of the Ultimate Mini Pile at a depth of 10 meters showed a significant difference between various methods. Sondir showed a value of 109.17 tons, SPT 80.9 tons, 70 ton manometer reading, and the computer program of all pile 51.4 tons. This difference was believed to be caused by several factors:

Factors Causing Differences

The differences in the results were believed to be caused by the following factors:

Soil depth: Variation of soil types and conditions at different depths can affect the carrying capacity of the mini pile.
Types of soil: Although in close distances, soil types can vary, thus affecting their ability to support loads.
Operator accuracy: The accuracy of the operator in carrying out the sondir test and SPT can affect the results obtained.
Calculation parameters: Each method has different parameters and assumptions, so that it can produce different results.

Calculation of a Single Mini Pile Decline

Calculation of a single mini pile decline using the load transfer method showed a decline of 9.22 mm. Measurements in the field at two experimental points produced higher numbers, which were 24.40 mm and 11.89 mm. This difference may be caused by factors such as variations in soil conditions in the field and the influence of additional loads that are not calculated in the model.

Conclusion and Recommendations

This case study shows that the selection of the investigation method, the accuracy of the implementation of the test, and the right calculation is very important in determining the carrying capacity of the mini pile and the calculation of the decline. Comprehensive analysis is needed by considering various factors, such as soil, depth, and load, to achieve accurate results and guarantee building stability. The results of calculations and measurements in the field need to be combined to get a more accurate and convincing picture.

This study also emphasizes the importance of strict monitoring and control during the development process to ensure results in accordance with planning and minimize the risk of excessive decline.

Limitations of the Study

The study has several limitations, including:

Limited data: The study was limited by the availability of data, which may not be representative of the entire project.
Methodological limitations: The study was limited by the methodological approaches used, which may not be comprehensive or accurate.

Future Research Directions

Future research directions include:

Investigating the effects of soil depth and type on the carrying capacity of mini piles
Developing more accurate calculation methods for determining the carrying capacity of mini piles
Investigating the effects of operator accuracy on the results of sondir and SPT tests

By addressing these limitations and future research directions, the study can provide a more comprehensive understanding of the carrying capacity of mini piles and the calculation of decline, which can be applied to future construction projects.
