Abstract

Foundation specialist contractors already have guidelines for carrying out bored pile work. However, in its implementation there are risks that could potentially lead to delays. This is because in carrying out bored pile work there are risks that are not visible in the ground. Therefore, existing implementation guidelines need to be developed based on risk. This study aims to identify and analyze the potential risks that will occur, as well as the responses that need to be taken in the form of preventive and corrective actions, so as to develop guidelines for the implementation of risk-based bored pile work. The method used in this research is a qualitative analysis and Multi-Attribute Utility Theory (MAUT) analysis. The dominant risk factors were found, namely the existence of utilities in the ground, improper age of the tool, collapse of the surface soil around the borehole, changes in the work implementation schedule from the owner and low labor productivity. Therefore, the risk response is to carry out Ground Penetrating Radar (GPR) and area mapping to find out the utilities that are in the ground, replace tools that are more appropriate, use preliminary casing, carry out careful planning and bring in an experienced workforce. It is hoped that the guidelines for implementing risk-based bored pile work can be used by specialist contractors to minimize the impact of negative risks that may occur in the implementation of bored pile foundation work.
