Subsurface Evaluation: A Case Study at Universiti Pertahanan Nasional Malaysia, Malaysia

Accurate subsurface information is essential for determining rock and soil layers for excavation works. This paper presents a subsurface evaluation (rock and soil) through the correlation of seismic refraction and 2-D resistivity values in a weathered sedimentary rock area. Borehole log data were also used to validate the subsurface data obtained from both methods. The study site was located at a construction site within Universiti Pertahanan Nasional Malaysia, Kuala Lumpur. The subsurface profile was produced by integrating data from seismic refraction, the 2-D resistivity method, and borehole logs to provide a more accurate depiction of the subsurface, particularly the bedrock profile.
