44 DEVELOPMENT OF SHIPYARDS IN THE 



Combination Shops. — This factor is in square feet and includes all marine ma- 

 chinists and marine electrical shops, all pipe, copper and sheet metal shops. This 

 item is capable of being subdivided into several branches, but the information is not 

 available. 



Miscellaneous Buildings. — This factor is m square feet and is the floor area of 

 the many buildings that do not come in the above divisions, excluding the main 

 office building and restaurant, barracks and hospitals where they exist. 



Boiler Shop. — This factor is in square feet and is the floor area of buildings 

 used for the manufacture of boilers. Some yards have no such shops, while some 

 have shops with surplus capacity. The latter are noted so far as possible. 



Foundries. — This factor is in square feet of floor space. Comparatively few 

 plants have complete foundries for all classes of work. Some have brass only, and a 

 few have foundries with surplus capacity. These have been noted as far as possible. 



The plant factors have been plotted for convenience of comparison. Those for 

 Classes B and C are on Chart E, Plate i8, and those for Classes D, E and F on 

 Charts F and G, Plates 19 and 20. These charts make it possible to quickly com- 

 pare the make-up of the several plants and to draw general conclusions. The 

 plants have been assembled in order of the number of ways, with the largest first. 

 In general, the several factors appear to have but little relation to the number of 

 ways in the plant, there being a great variation in size of the factors for plants 

 with equal number of ways. A few of ihe factors have fairly well-defined aver- 

 age increases with the increased number of ways. Others do not. Several appear 

 to be of the same size for four, five and six ways. The factors for machine shop, 

 smith shop, boiler shop and foundries are shown as they have been obtained, but 

 owing to the difference in the extent to which they are used in many plants, and their 

 absence in others, it is difficult to draw definite conclusions. Where plants are 

 known to be deficient in capacity or have a surplus capacity, this fact has been so 

 noted on the charts. 



A careful examination of the data which has so far been prepared indicates 

 very little uniformity in the extent of equipment provided for the various yards. 

 Even in the yards of greatest efficiency, as indicated by their output, there is very 

 little uniformity. This leads to the conclusion that the efficiency of a shipyard is less 

 dependent upon plant layout than upon other factors, the principal one of which is, 

 of course, the personnel. There is no doubt, however, that while plant layout is not 

 the most important factor, it is nevertheless one of great importance in the estab- 

 lishment of a building yard. The study of a relation of plant layout to efficiency in 

 plant output has not been contemplated in time to be outlined in this paper. It is 

 therefore not safe to draw any conclusions at this time as to the exact function of 

 plant layout in determining efficiency. 



The Shipyard Plants Division of the Emergency Fleet Corporation was organ- 

 ized under Admiral H. H. Rousseau, who remained as manager of the division until 

 May I, 1919. It is desired to acknowledge the valuable aid rendered by Mr. J. E. 

 Tonnelier, head of the Records and Progress Section of the Shipyard Plants Divi- 

 sion, and Mr. Sherman A. Jubb, supervising engineer, in the preparation of this
