Effect of Pile Foundation Implementation on Environment, Cost of Elevated Railway Line Construction Project Between Solo Balapan-Kadipiro KM 104+700 to KM 107+000 (Phase II)

With the development of traffic flow, infrastructure development is needed to create comfort and safety in driving. In addition, the development must also be supported by good traffic management in order to reduce the traffic density of vehicles, one of which is the construction project of the Elevated Railway Line between Solo Balapan - Kadipiro KM.104+700 to KM.107+000 (Phase II). This research was taken from the Elevated Railway Development Project between Solo Balapan-Kadipiro KM+ 104+700 to 107+000 (Phase II), which is located at the Joglo Intersection in Banjarsari Village, Surakarta City. The research method used is quantitative and qualitative research methods. From the research results of pile driving work: air pollution, noise pollution, and vibration caused by the pressure of the drop hammer tool hitting the pile, from these influences, the main effect is that the vibration caused results in buildings and building structures, so that many influences interfere with human comfort. The amount of analysis of the bearing capacity of the pile: (1) The stress that occurs in the transportation of 32.67
