Abstract:

For any component, the production process, the necessary degree of standardization and the scale of activity are interrelated the degree of standardization restricts the choice of process and the capital investment required, which in turn determines the minimum scale of operation. For standardization to be successful in reducing the costs of components, the number of components and their individual functions must be chosen so as to match, as far as possible, the range of conditions most frequently found. But the cost of the structural components accounts for only part of the cost of a building, and the use of standard components will be judged ultimately by its effect on the total cost. Thus the designer should consider the effect of the design on site operations and ensure that the manufacture, delivery and assembly of components are co-ordinated. Of particular importance are the effects on site operations of considerations of accuracy and the specification of dimensional tolerances. There is a need for information on the sources of inaccuracy and how accuracy can be controlled, and on the relationship between the accuracy achieved and the cost of achieving it. There is also a need for further consideration of the effect of the specifying of tolerances on structural design. Author
