A geophysical and geotechnical investigation survey was carried out to determine soil strata for site buildings in a site in Ibadan, Oyo state, south western Nigeria, using electrical resistivity method. Four vertical electrical sounding stations were surveyed for the above investigation, the methods adopted in the investigation was purely based on information and communication technology which have great impacts on the sites investigations. Schlumberger array was used for the VES with maximum current electrode separation (RS/2) of 55m and readings of the resistance observed from the Terrameter were converted to apparent resistivity. The resistivity low in VES coincides with the high conductivity values which depicts the weathered zone in the study area. The weathered basement thickness is considered adequate for any overlying pressure from the camp attendants that will be seated on it. The result shows a typical three layer model in all the parts. The strata include the topsoil, clayey weathered layer and the fresh basement. It has been discovered from this study that the zone which the building will seat upon is thick enough to accommodate the building and will not have any adverse effect on it in the nearest future.  It is therefore recommended from the impacts of information and communication technology it has shown that the site is suitable for the proposed camp site.
