This study aims to assess the site effect of the Bukit Timah Granite area in Singa-pore via 2D dynamic numerical modeling and further comparison with previous geophysical testing results. A 3D geophysical model was created via combining geophysical investigation data with borehole data and geological maps of the region, and then several 2D geological cross-sections were extracted. Those cross-sections were used for dynamic numerical modeling of seismic ground motion and for calculating site amplification using the Universal Distinct Element Code (UDEC). The results show that the fundamental frequency (f 0 ) is in a good agreement between dynamic numerical modeling and horizontal to vertical spectral ratio (HVSR). Thus, the dynamic numerical models would be used for site effect analysis in the seismic hazard assessment.
