This study deals with development subsoil geoengineering dataset and modeling of parameters in Okeigbo area of Ondo State, Southwestern Nigeria. The study employed geophysical methods, geotechnical survey, hydrogeological, and laboratory analysis. Findings revealed the subsoil to be clayey with low compressibility and plasticity. The clay mineral group is dominantly illite-montmorrilonite, of low activity (0.36), and hydraulic conductivity of 3.67E-08 cm/s, while the plasticity index is 23.4 %. The depth to groundwater ranged from 2.2 m (in well) – 18 m (in borehole). The depth to basement rock is between 8.2 – 31.5 m (avg. 20.9 m), indicating a moderate to deep weathering profile, able to support burial of engineering utilities such as mast, transformer, gadgets. In regard to pavement construction, the soils are unsuitable for subgrade, base and sub-base courses with CBR less than 7% and GI of 14 (avg.). However, a recommended minimum thickness of 79 – 140 mm was obtained from design curves for flexible pavement. The average allowable bearing capacity of the soil for square and round foundations is 320 KN/m2. The total settlement obtained varies between 23.92 – 29.77 mm for structural pressure of 100 KN/m2. The embankment suitability index of the soil suggests an expanding, but not collapsible construction material. Summarily, the subsoils have very low suitability/workability index, hence poor/fair performance for roadway, foundation, canal sections, and earth fill dams. The empirical models gave correlation coefficient of: MDD/PI vs. CBR (0.0046), LL vs. coefficient of consolidation (0.0127), PI vs. undrained shear strength/effective overburden (0.0074), PI vs. angle of shearing (0.0420), dry density vs. angle of shearing (0.4022), suitability index vs. CBRs (0.0968), clay contents vs. PI (0.0777). Schist and quartzite dominated the area, having high value as foundation constructions, aggregate in pavement, and building stone, hence can be trusted in most engineering construction works.
