THE SENSITIVITY OF DETAIL DESIGN TO INITIAL AND WHOLE LIFE COST

This paper considers some of the criticisms made of whole life costing and investigates the effect of reducing the durability of components to cut back on design life in the case of bridge construction. The author considers that whole life costing makes a valuable contribution to decision making but stresses the need for more information on historical costs and life expectancies. The use of spreadsheet software to calculate whole life costs is outlined. Various bridge components are then examined for their effect on whole life costs including a) construction materials, b) substructures, c) expansion joints, d) bearings, e) waterproof membranes and surfacing, f) parapets and g) drainage and service ducts.
