Definition of Foundation                                                                                                          Definition of Shallow Foundation




                       •  The foundation of a structure is defined as the part of the structure in direct contact of
                          with the ground and which transmits the load to the ground (Tomlinson,2001)                                                  •  Shallow foundation is a foundation constructed in depth of not exceeding 3.0m
                                                                                                                                                           from formation level. The depth to width ratio of the foundation is D/B ≤ 3

                       •  Generally, there are two (2) types of foundation:

                                      Shallow Foundation
                                      Deep Foundation

                                                                                                                                                                   Soil bearing capacity
                                                                                                                                                                   Differential settlement ≤ 25mm (Das, 2004)
