In Ethiopia most of the buildings and roads are constructed without thorough investigation of geological environment and materials. This is due to during all civil engineering structures site investigations and constructions on the odd occasion engineering geologist are involved. This made different problems on engineering structures in Ethiopia such as subsidence, cracking and settlement of buildings and roads. Not only this but also less experience of designing and consulting engineers in the construction company. To reveal that the root cause of this problemthe detail research finding was needed to solve these difficulties in construction around Arbaminch town. To characterize the area this research work used visual observations of the geology, geo-botanical condition, measuring of horizontal and vertical variation of the lithology, drilling trial test pits and trenches as well as engineering characterization of soil in the laboratory. Based on these, different zones of engineering geological maps were produced depending on different situations. The parameters were geological structural measurements, surficial geo-dynamic activities, geotechnical characteristics of geological materials, and geo-botanical conditions.The basic scenario identified during this research is soil types and its thickness, the undulating surface of sound rock surface and groundwater fluctuation. Based on these results it is better to use deep foundation or deep excavation to get sound rock with uniform bearing capacity or to replace weak geological materials by better geological materials.
