Constructing embankments on soft clay deposits poses significant challenges in geotechnical engineering, especially in terms of ensuring stability and controlling settlement to meet design requirements. The observational method is commonly used in such cases, allowing for adjustments to the design during construction. Matsuo (1977) proposed a construction control chart that combines vertical and lateral displacements, making it particularly useful for predicting the failure of embankments on soft ground during construction. Soil properties, loading history, and environmental conditions all have a substantial impact on these predictions, even with small variations. To evaluate this, the paper compares field observations from a case history with results from finite element analysis (FEA) conducted using PLAXIS 2D. The finite element analysis shows a good agreement with the observed field data. The analysis of results shows that 22% and 36% of reduction in maximum settlement and lateral displacements respectively. Finally, the stability of the embankment is assessed using Matsuo's construction control chart which agrees with the construction stages.
