ABSTRACT

This project work is concerned with assessment to different types of foundation and their mode of construction though looks like a literature review but entails full information and chosen.

Foundation samples were limited to three different locations within Ilorin metropolis. Terzaghi equation was used for determining soil bearing capacity of the three cohesionless soil samples taken.

The result obtained from the calculation shows that the soil in the three foundation Examined can resist any excessive settlement of super-structure load without excessive settlement of shear and it shows a good indication that the soil is good to be used as a sub grade or sub-base materials for construction.

In general the soil material in those three foundation posses similar characteristic.
