Analysis of the Carrying Capacity of the Pile Foundation of the Group in the Construction Project of the North Sumatra DPRD Building in Medan

Introduction

The construction of high-rise buildings such as the North Sumatra DPRD building requires a strong and sturdy foundation to withstand the burden of the building structure. The foundation of the pile, which is also known as a deep foundation, is the right choice to support the heavy burden of the building structure. The foundation work is a crucial stage in civil construction, as it is the main buffer that holds the burden of the building on it. This article will analyze the carrying capacity of the group pile foundation used in the North Sumatra DPRD building construction project. This analysis aims to ensure the foundation is able to support the burden of building structures safely and stably.

Background of the Study

The North Sumatra DPRD building is a high-rise building that requires a strong and sturdy foundation to withstand the burden of the building structure. The foundation of the pile is the right choice to support the heavy burden of the building structure. The pile foundation is a type of deep foundation that is used to support heavy loads. It is a crucial stage in civil construction, as it is the main buffer that holds the burden of the building on it.

Methodology

This study uses field data and laboratory tests to calculate the carrying capacity of group piles. The data used include sondir test results, SPT (Standard Penetration Test), and manometer reading on the Hydraulic Jack system. The data is then analyzed using various methods, such as Aoki and De Alencar, Mayeroff, and other methods that are in accordance with the type of soil and field conditions.

Results of Analysis of Carrying Capacity of Piles

Based on the data obtained, the analysis of the carrying capacity of ultimate piles at a depth of 21 meters shows various results.

Aoki and De Alencar Method: QULT POINT-1 = 260.62 tons and POINT-2 QULT = 251.31 tons.
Mayerhoff Method: Point-1 Qult = 455.30 tons and Point-2 Qult = 494.55 tons.
Mayerhoff Method (SPT Data): Point-1 Qult = 230.65 tons and Point-2 Qult = 228.54 tons.
Manometer Reading: Qult = 327.87 tons.

Factors Causing Differences in Carrying Capacity

The difference in the carrying capacity of piles from various methods of analysis is caused by several factors, namely:

Land Depth: Differences in the depth of the soil that are reviewed will affect the type and condition of the soil that is passed by piles, so the carrying capacity is also different.
Types of Soil: Variation of soil types, even at adjacent distances, can affect the carrying capacity of piles.
How to Carry Out Testing: Operator accuracy in conducting sondir tests, SPTs, and manometer reading will affect the results of the test.
Calculation Parameters: Each analysis method uses different parameters and assumptions, so as to produce the results of not the same carrying capacity calculation.

Conclusions and Recommendations

The results of the analysis of the carrying capacity of the pile group in the North Sumatra DPRD building construction project showed that the planned pile foundation had sufficient carrying capacity to withstand the burden of building structures. However, further evaluation needs to be carried out on the results of the analysis to ensure the foundation design is in accordance with the field conditions and technical requirements. Recommendations to note:

Monitoring Soil Conditions: Performing monitoring soil conditions periodically during the construction process to ensure that there is no significant change that can affect the carrying capacity of piles.
Increased Accuracy of Testing: Ensuring the accuracy of operators in conducting field testing to get accurate data.
Foundation Design Optimization: Conducting Optimization of Foundation Design Based on the results of the latest analysis and field conditions to improve the safety and stability of the building.

Conclusion

By paying attention to these factors, it is expected that the foundation of group piles in the North Sumatra DPRD building construction project can function properly and provide a strong and safe foundation to support the building structure.
