Abstract
The Egyptian government is active in multiple areas designated for industry and urban development on the outskirts of both the capital and various governorates within newly established cities. The proposed site for the creation of the industrial zone of New-Cairo City is regarded one of Egypt's most promising commercial and combined services zones. The study's primary goal is to map the region's subsurface geological conditions and interpret the findings for geotechnical qualities of the underlying materials.

The study aims to evaluate the properties of the subsurface layers to determine their suitability for construction and engineering purposes. The study is a case study that focuses specifically on the combined services area of Madinaty, to assess the suitability of the subsurface layers for geotechnical engineering purposes. To gather data about the subsurface layers, the investigation employed two geophysical techniques: Electrical Resistivity Tomography (ERT) and Shallow Seismic Refraction (SSR). SSR is used in the study area to identify dynamic geotechnical characteristics of the base layers using the P-wave and S-wave velocities. Two sub-surface layers are identified based on the velocity values of the Geo-seismic layers. The first layer is composed of mixed soil of sand, clay, and gravel, where the second layer composes of hard Limestone.

According to all the criteria, regarding engineering aims, the area is divided into high, moderate, and low competent-material zones with varying degrees of fittingness. The current study suggested sorting the fundamental subsurface materials in the high and moderate zone for engineering purposes.
