with staff and key personnel of CINCPAC and COMSERVPAC on such problems as POL storage and handling, equipment availability which could affect site planning and design, details of materials to be considered and related corrosion problems, communications equipment and system design, hydrographic and oceanographic information related to the Atoll, wage scales, and water distillation. These discussions provided much information which could be used by the Engineering Division in establishing planning criteria, The meetings at the Public Works Office of the Fourteenth Naval District were also extremely fruitful inasmuch as this office was directly concerned with design and engineering as well as construction throughout most of the Pacific Ocean. Design criteria for military installations in the Pacific were reviewed. Maintenance requirements, specifications, material, supplies, soil stabilization, logistic considerations, and other relevant problems were considered. It is noteworthy that during these discussions the comparison was drawn between stateside construction costs and overseas construction costs for various Pacific installations. It was reported to the members of the reconnaissance team that the ratio of overseas cost to stateside cost varied, depending upon the particular location in the Pacific Ocean area, between 1.75 and 3.0 and that the latter figure was perhaps more realistic for work at locations such as Eniwetok, which was somewhat off the beaten track and had no native population available for employment. Upon return of the reconnaissance team to Los Angeles, its members began the task of integrating the wealth of material accumulated during the trip with the information on equipment, prefabricated buildings, usage factors, and similar items of information worked up by engineering personnel at the Home Office. The screening process was tedious and, because of security limitations, the wealth of experience available througout the Engineering Division and clearly applicable to the job at hand could not be fully utilized. However, by the first week in November 1948, considerable progress had been made in resolving the data collected into the form of recommended criteria. At this time it became apparent that the master planning of the Project could be expedited materially if "P" approved personnel were given access to isolated phases of the problem for study. Permission was granted to do this, and thus it was possible to utilize the added experience which could be brought to bear on the subject and new impetus was given to this phase of the work. It was also apparent at this time that one of the major considerations affecting the production of a master plan for the Proving Ground was the determination of the intended period of utilization of the facilities. The type of structures and equipment to be recommended, the nature of installations, and the over-all philosophy of operation would obviously be quite different if only a single operation were planned in 1951 than if it was intended to establish structures, facilities, equipment, and installations which could be used for a series of operations to be performed over a number of years.
