In order to obtain efficient design, stable and optimal with a good characteristic of quality, one of the techniques that can be convinced is called life cycle cost. Life cycle cost is a process of determining the amount of costs related to an asset, including initial costs, maintanance costs, and repair costs. It was found that both relationships were significant and positive. The purpose of life cycle cost is to get the saving cost and time efficiency, which does not rule out its function and quality. In this life cycle cost analysis, the diaphragm wall is selected to replace the soldier pile. The cost savings obtained are 23% of the initial cost of the soldier pile’s retaining wall work. The process of diaphragm wall is a lot faster 2-3 times than the work of soldier pile retaining wall. Based on the results of the initial costs and maintanance costs, it can be interpreted that the method of diaphragm wall can allow much greater savings than using the soldier pile retaining wall method.
