Development task 2... with label sketch - Assignment ExampleThe understanding of the concrete has to be greater than 500 millimeter. From ground level, the enlightenment of the concrete must be greater than 1500 millimeter (Cyril, 2003 110).Since the ground condition has firm ashes, therefore there is a need to consider the depth of foundations. Clay exhibits the property to shrink or contract depending on the moisture content present 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 foundation may experience settlement to a significant level. For this case, it is essential to consider the depth of the foundation. A trench carry out foundation is thus ideal for this type of range condition. Research suggests that trench fill foundations are quicker to prepare than deep strip foundations. This means that there is less(prenominal) disruption at one time the bui lding 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, gridiron or mat foundation. In this case, the suggested foundation is mat foundation. Because of varying ground conditions, majority of the isolated footings would withdraw large areas and thus, it would become uneconomical (Terzaghi et.al, 2006, 256)l. According to the British Code, Where the subsoil is very weak the load postulate to be spread all over a greater area. This is achieved by casting a slab of concrete over the whole ground area and thickening the slab where walls are to be placed(Perry & Perry, 2009, 118).The design of any strengthen concrete structure aims at a suitable and economical design and for this purpose, ma t foundation is ideal. A mat foundation is often used by designers when isolated footings may
