ABSTRACT
It is important that the structure of a dwelling is considered as a whole and not just as a series of individual components. A sound and satisfactory roof and well-constructed walls are, obviously, vital elements but more often than not they in turn are dependent on the internal structural features of partitions and floors to provide the necessary support and restraint. Without these, external walls can develop leans, bows and bulges and roofs can sag. Even when the necessary support and restraint are provided, inadequacies of design and construction can undermine what would otherwise be satisfactory construction elsewhere. For example, an internal partition wall could well be carrying a substantial load from floors and roof. Failure of its foundation, causing it to settle, can lead to sloping floors and a distorted roof and possibly disturb the stability of the external walls. It is vitally necessary, therefore, to establish during the internal inspection which partitions provide support to the structure above.
