Excerpt from book: Each job or group of a new vessel can. be estimated upon in this manner and all these estimates tabulated by jobs and by operations, all on one large sheet of paper. During the construction of the vessel, this sort of an estimate would be useful both to the contractor and to the customer (or inspector), in estimating monthly the value of the vessel as she stood on the stocks. The progress of work in tenths and in dollars could be checked off both by jobs and by operations. PiECE-WoBK Prices As a temporary standard with which to compare costs of operations in similar work, a simple set of piece-work prices will be introduced. It is hoped that if carefully studied, especially the riveting schedules and the table of allowances for '' scattered'' work and for non-standard conditions, they will in a measure point the way for each estimator who has no standards, to set up his own standards of comparison, taken from his own data. Some of these prices may be low or high for a particular plant, as they were of course set, in certain ship construction and repair plants, with consideration being givento the equipment and facilities, to the organization and management, and to local conditions and prevailing wages. In estimating the cost of any particular operation, we must first compare our own recorded data with these prices or costs, and get the average ratio between them. The simplicity of the classifications used (or of any other simple classifications) adds greatly to the rapidity and ease with which any ordinary estimate can be made for any number of units, however small, by using the judgment which comes from experience in classifying the conditions of the specific operation before us as to (1) accessibility, (2) complexity, (3) contiguity of the units; by assigning to the operat...
