Foundations - (1)
  1. Function
    1. Evenly transmits load(s) to the ground the foundation rests on (subsoil) safely & eliminate damaging ground movement during construction and throughout the anticipated life of the structure
      1. Load
        1. Dead
          1. Structual
            1. Wind
              1. Imposed
              2. Damaging ground movement
                1. Frost heave - caused by freezing and expanding water
                  1. Soil movement
                    1. Change in volume of water in ground - when soil wet / dry
                    2. Subsidence
                      1. Trees
                        1. Abstraction from vegetation
                        2. Weather
                          1. Bearing Capacity
                            1. Defined: Maximum Pressure of ground
                              1. Problem: Load exceeds bearing capacity
                                1. Downward movement of foundations occurs
                                  1. Solution
                                    1. Reduce load carried by foundation
                                      1. Increase plan size of foundation to reduce load per unit area
                                2. Soil heave
                                  1. Soil shrinkage
