A Trench Fill psychiatric hospital - Assignment ExampleSince the ground condition has firm clay, therefore there is a need to catch the understanding of natess. Clay exhibits the property to shrink or contract depending on the moisture content manifest in it (Kenneth, 199325). At the same time, if the surrounding area has trees, there is a possibility that the trees would absorb the moisture from the clay and hence, the mental institution may experience settlement to a significant level. For this case, it is essential to consider the depth of the foundation. A encroach fill foundation is thus ideal for this type of site condition. Research suggests that trench fill foundations are quicker to prepare than deep strip foundations. This means that there is less mental disturbance once the building work starts and not as much labour time will be needed. It is less likely that subsidence will occur in cases where there may be changes in the soils substrata (Mosley & Bungey, 2000, 48).The site has different ground conditions and has different soils. Thus, it has a weak bearing capacity. For this purpose, the ideal foundation would be strip, grid or mat foundation. In this case, the suggested foundation is mat foundation. Because of varying ground conditions, majority of the maro wizd footings would have large areas and thus, it would become uneconomical (Terzaghi et.al, 2006, 256)l.

It comprises of reinforced concrete slab, which would be laid over the uneven ground and thus, it would bear the load of the entire structure. two-dimensionality foundation is also ideal for this type of ground condition because of differential settlement. The aim of the mat foundation is to minimize differential settlement (Coduto, 2001, 289). The massive loading of the structure can cause the soil to wedge and thus, the structure may experience settlement. For this purpose, the mat is used as an option in order to accord the entire loads of the buildings and to remove differential settlement.
