Consolidation settlement in clay soils can be predicted by analyzing the consolidation parameters. Consolidation parameters were obtained from the results of a laboratory consolidation test using an oedometer and rowe cell. The rowe cell can measure pore water pressure, soil saturation, and back pressure as a simulation of field condition while the Oedometer cannot. However, there are significant differences between the results of the analysis with the consolidation settlement occurred in the field caused by drainage conditions, the micro characteristics of the soil structure, and the thickness of the soil layer. Therefore, it is necessary to validate the results of settlement in oedometer and rowe cell consolidation analysis with the value of settlement of experimental results. The method used is a laboratory consolidation test using an oedometer and rowe cell as well as a laboratory-scale experimental consolidation test. The results obtained 79% of differences between experimental and oedometer, while rowe cell had a difference of 37% from experimental. Based on this, analysis using rowe cell consolidation parameters can predict a settlement in consolidation in the field more accurately than oedometer, because it has a smaller difference in value.
