The knowledge of soil behavior and conditions in subsurface is essential for the development of projects, through the resistance properties obtained in the dynamic penetration test. The frequency by which SPT (Standard Penetration Test) Field tests, and Laboratory tests are carried out in urban area is large, and the volume of results makes possible to acquire a great deal of geological and geotechnical information of great importance for the design of various types of Engineering works. The real target of this study are the different lithostratigraphic units that include the surface soils and the soil of the substrate of a part of Luanda province. The aim of this work is to present the distribution based on substrate depth starting from the analysis and treatment of results of SPT in urban area as an element to be taken into account in the requalification and reordering. Activities that are currently taking place in order to use and occupy rational aspects that prove to be very useful when seeking solutions that reach levels of safety, economy and optimization of cost versus benefit. In addition, the present work constitutes also, an approach on the importance of Geology in the planning of the city of Luanda and its surroundings.
