Abstract
The development of urban areas is characterized by significant growth and urban expansion, which leads to the appearance of satellite towns, also known as dormitory towns. In order to reduce this speed of horizontal urban expansion, it was wise to think about the use of urban subsoil, which leads to the improvement of urban planning in the form of vertical construction. Apart from the fact that this approach proves to be surrounded by several constraints of a geological, hydrogeological, geotechnical, and socio-economic nature, the volume and potential value will also have to be assessed before proceeding with this type of construction. In this sense, the different factors influencing the use of urban subsoil, as well as the methods for analyzing the potential of urban subsoil, on a theoretical basis, will be shown - in order to better utilize it. Accordingly, the case study of Rabat`s city, the capital of Morocco, will be considered. The project consists of building a two-level underground car park near a historic earthen wall. In order to assess the possibility of this type of excavation, it was more appropriate to carry out recognition trials and other stability tests. Subsequently, it was evaluated using the principle of the observational method to find out how the frequency of the excavation machines affects the stability of the surrounding wall. As a result, the frequency of the vibrations generated by the excavation machines had to be adopted using a geophone during the construction and commissioning phase of the car park.

Keywords
