The foundation erection work is a job that has a high enough complexity. In making the decision of the type of pile and the method of erection, practitioners have many choices with various conditions in the field. Decision making will result in an impact during the foundation erection process. This study aims to analyze what are the impacts caused by the choice of pole type and piling method. A preliminary survey was conducted together with four experts to verify and reduce the 11 impact indicators obtained from the literature study, obtained 6 impact indicators which are quite relevant according to experts and will be used in the questionnaire survey. The questionnaire survey was conducted on 45 practitioner respondents who had carried out foundation building work. Data analysis validity and reliability tests were carried out on the questionnaire data. It was concluded that there were three main impacts that occurred due to the choice of the type of foundation pile and the piling method, namely environmental impact, economic impact, and social impact. The main impacts are broken down into six impacts including the use of fuel, ground vibration, fuel and material costs, equipment and labor costs, workplace safety, and noise.

One of the jobs that have a high complexity in civil works is foundation pile work. Practitioners are often faced with many choices and various conditions in the field in making decisions about the types of piles and methods of piling. The selection of the type of piles and the method of piling will have environmental, economic and social impacts. Many conditions need to be considered when making this selection. This paper presents a literature review in the study of influence in the selection of pile type and foundation piling method in problem identification and approaches. The results of this study support the influence factor used by case studies of decision-making taking into triple constraint in project management.
