ABSTRACT
The economy of prefabrication depends very much on the adaptability of a building designed for a specific use to the resources and method employed by a particular precaster, who will eventually be selected to manufacture and erect the prefabricated components. It also depends on the total volume of elements to be produced for this particular project and similar projects. Naturally, the larger a series of similar elements, the smaller will be the cost per element associated with design, molds adjustment, and task learning of the production crew. Even better economic results can be attained if elements used for project construction are identical or similar to elements already produced in the plant for other projects. In such a case, no significant setup expenses are needed.
