Further considerations - Structural safety factors

The safety of a structure depends on the successful combination of design and completed construction, particularly — (a) identification of hazards to which the structure is likely to be subjected and assessment of the risks using the conditions that can reasonably be foreseen during future use; (b) the self-weight of the building; (c) the loads imposed on the building including those arising from climatic conditions; (d) combinations of (a), (b) and (c); (e) properties of materials; (f) safety factors; (g) the nature of the ground; (h) impact on and by other buildings; and (i) workmanship. The numeric values of safety factors, whether expressed explicitly or implicitly in design equations, or design values, should be derived from considerations of the above aspects of design and construction as a whole. A change in any one of these aspects may disturb the safety of the structure.
