Six (6) Schlumberger soundings were also performed radially in the site with half-current electrode separation (AB/2) of 120 m. Numerical modeling of an orthogonal set of 2-D apparent resistivity data acquired in an engineering site in a 100 × 70-m 2 rectangular grid using the Wenner electrode configuration was used to create models of subsurface resistivity which converges with the field data. The study presents one of the geophysical methods, electrical resistivity tomography (ERT), which allows for an accurate and spatially instant recognition of the subsurface geology and the phenomena occurring in it. Geophysical investigations play an important role in the geotechnical detection of subsoil properties. In the design of engineering structures, collaborative efforts must be ensured to determine in-situ subsurface soil conditions and depth to competent layers across any proposed site so as to ensure the stability of civil engineering structures, to avoid the devastating effects of structural failure and collapse rampant of late.
