CHAPTER 12,2 ORIGINAL RECONNAISSANCE REPORT ESTIMATES On the basis of the information secured during the reconnaissance survey in October of 1948, supplemented by aerial photographs, maps, and charts, the Estimating Department was instructed to assemble a cost estimate for inclusion in the Reconnaissance Report submitted to the Atomic Energy Commission in January 1949. This estimate was prepared in accordance with the procedures described in Chapter 12.1, and was based on the following criteria: 1, The proposed development of the Eniwetok proving ground was to be made up of five phases, Phase I was to constitute the preparation of the Reconnaissance Report to be submitted in January 1949. Phase II was to constitute a period of time between February 1, 1949, and July, 1949, when personnel would be sent to the Atoll to prepare preliminary surveys and general rehabilitation to accommodate a construction camp. Phase III was the construction program between July 1949, and December 1950. Phase IV was to be the experiment period between December 1950, and May 1951. Phase V was to be the roll-up and maintenance period after the experiment ending in May 1951. The construction camp was to accommodate a total force of 900 men, of whom 600 were to be construction workers and 300 were to handle the operation of the several camps, Quartermaster supplies were to be made available for this job. Boats, vehicles, and aircraft were to be available from other Government agencies to the contractor on memorandum receipt, at no cost, De Transportation of personnel and materials to and from the Jobsite was to be provided by MATS at no cost, Construction materials were to be transported to the job by Navy water transportation at no cost, During the Phase IV or the experiment period, it was assumed that the Atomic Energy Commission would have 200 people based ashore, and that Holmes & Narver would make available a support crew of 100 mechanics and helpers to aid this group. It was assumed that all other visitors, guards, etc, would be quartered aboard ship or on Eniwetok Island, without service by Holmes & Narver. The initial interim construction camp was to be established on Eniwetok Island using rehabilitated facilities until such 12-5
