In bridge construction, foundation work is one of the main jobs. In one construction work, foundation analysis and design can be done with a combination of methods and testing, so that the predictions of the carrying capacity of the foundation as well as possible. However, the foundation capacity of the country has a variety of uncertainty that needs attention. Generally, uncertainty of analysis and foundation design has been handled by the experience and consideration by experts. But with the reliability method, uncertainty of analysis and foundation design becomes more quantitative. This research was conducted to determine the reliability of the Jakarta-Bandung fast train foundation divided into four zones, namely Zone Lowland (Jakarta), Zonahigh Land (Bandung) and Clay-Shale Zone and Non Clay-Shale. The results of the static load test and dynamic code are compared with the soilinvestigation data using the SHAFT program. Overall statistics of data (on average, standard deviation and variation coefficients) are used as information on reliability. The final result of this study is to find out the uncertainty of the foundation design and get reliability values on the drill pole foundation.
