Bearing Capacity of Soils - Lab Report Example If this is not properly done, then the structures are likely to collapse, resulting in massive catastrophes. Sound engineering principles should be employed in the design of such structures in order to avoid potential loses in human life and property (William Powrie 53).   There are two major types of foundations; shallow and deep. While shallow foundations are located just below the structures they support, deep foundations extend deep into the earth’s crust. Shallow foundations are thus also called footings or mats, whereas deep foundations can also be called piles, or drilled shafts (Braja M. Das 123). The type of foundation used depends on two factors; the size of the structure to be built, and the category of soil on which the structure is to be built. Big structures require bigger foundations than smaller structures. On the other hand, organic soils also require bigger foundations compared to cohesive soils.Problem Description1.  Calculate the required size for a bui lding column footing under a given load.2.  Determine the effect of varying water contents on the compressive strength of the soil.Procedure  The lab was conducted following the following procedure:1.  A test specimen with known percentage of water was selected. The group used soil with 15% water content. This specimen was created by mixing 22.5 grams of water with 127.5 grams of dry clay.2.  The next step involved filling the mold with the soil-water mixture in three equal layers using the tamping device. The top of the first and second layers.
