The Wenner array was used for the ERT survey, with the varying electrode separations of 1.0, 3.0, 6.0 and 8.0 m respectively, and the electrode increment of 5.0 m across the three (3) traverses that were established in the study area. The traverses were of distance 100 m each, with W-E orientation that would enable the subsurface imaging of the study area. The subsurface features experienced in the study area were topsoil/laterites, weathered layer, clayey zone, and bedrock. The inverse model along traverses 1 and 2 revealed that the clayey zones beneath these traverses are very thick, which showed that the study area was unsuitable for construction of high-rise building without the certified building engineers’ advice.application/pdfQ Science (General), QC PhysicsArticle
