An up-to-date topic with which engineering geology can contribute to the requirements of practice and research, in particularthe needs of land use planning, state administration, building offices, developers, etc. is an analysis of new possibilities of providingreference information on the engineering-geological conditions by means of geographic information systems. The study in the presentedpaper deals with an evaluation of two geofactors. They are the character of rocks workability and Pre-quaternary bedrock. Workabilityis a significant limiting factor, which affects the used technology and financial demands of earth work. Especially in case of demandingconstructions, the Pre-quaternary bedrock is a geological environment which will have to be interacted with and must be taken intoaccount during selecting engineering foundation. The overall project was divided into five model areas (1-5), while this paper evaluatesa partial model area of no.1, which is defined by topographical map in drawing scale 1:10 1000 (topographic sheet No. 15-43-10).Namely they are Slezské, Moravské Ostravy, Vítkovic a Radvanice. The mentioned methodology was applied in the interest area forthe first time.
