Site Investigation for Plot No. 15, Sudan University of Science and Technology (SUST), Almogran, Khartoum - Sudan

Abstract

Soil investigation is used to determine the engineering properties of the building foundation soils which to be constructed by drilling a number of boreholes at depths commensurate with the nature and area of the building. The soil bearing capacity was obtained by taking soil samples in disturb or undisturbed soil samples at fixed depths of drilling ranging from one to one and a half meters. Soil classification known through the results of laboratory examinations on soil examples obtained after the site. This study aimed to identify the properties of the soil under the proposed building; it’s an academic building with twelve floors, and to evaluate the position of groundwater and the bearing capacity of the soil. In this study, samples were taken through five holes at different depths, and laboratory examinations were performed on them. The study showed that the soil classification of the site was performed at a depth of twenty meters for the total area of building and the calculation of the soil bearing capacity was carried out at different depths. Based on the calculations of the live and dead loads resulting from the building, the type, dimensions, and depth of the appropriate foundations were chosen, and it was found that the compound foundation (Pile - Raft) is the appropriate basis for the building.
