This paper compares the long-term settlements of a low-rise parking structure on piled raft foundations in reclaimed ground obtained by conventional leveling measurements with those obtained by multi-temporal InSAR analysis. The vertical displacements obtained from the InSAR analysis are found to be generally in good agreement with those from the leveling measurements. The study demonstrates the usefulness of SAR analysis for monitoring vertical displacements of buildings on soft ground. Moreover, these results indicate the potential of SAR technology to contribute to the establishment of more effective assessment techniques for infrastructure maintenance.
