WHOLE LIFE COSTING

This paper presents the whole life costing technique, which is a powerful method of determining the construction material and construction process, which are most likely to give the greatest economy in a specific investment scenario. The implementation of whole life costing on concrete columns requires an initial 'most likely outcome' analysis, but a real understanding of the situation is obtained only after investigating the sensitivity to variation of the many relevant parameters. The deterioration of concrete is associated with chemical changes, which must result from its external and internal environments and their ability to permeate the concrete to interact. The external environment is difficult to influence. Concrete technologists have most scope to improve the internal environment. The permeability of concrete is directly influenced by stress levels and associated cracking. The use of fibre-reinforced polymer resins (FRP) to provide tensile strength offers the prospect of greatly reduced chemical reactions in concrete reinforcement. Tables are given of some material and construction costs for concrete columns. Durability planning requires selecting a combined strategy for construction and maintenance, and perhaps also repair, to ensure that the structure can perform throughout its design life.
