ABSTRACT

This chapter examines the actual estimating process. Indeed, the project specification might have to be revised and re-issued more than once as the task list is developed. At the outset of a project however, the work breakdown can usually only be compiled in fairly broad terms. The task list must include not only all the obvious items of project hardware, but also every associated software job. When the estimates have been collected they will contain a large amount of data. Completion of a task list has established the basis for project cost estimating. In manufacturing projects the prime costs are likely to comprise mainly labour and materials with a relatively small subcontract element. A stage in the project preparation and planning process has been reached where many professional estimators, production engineers and work study devotees find themselves floundering well out of their depth. Drawings are the customary means of expression and communication for these people.
