CHAPTER Ii, SECTION 2 been made in November 1954. The Majuro and Jabor missions were completed by 6 April. Inclement weather prevented landing men and materials on Kili Island; the materials for this project were therefore landed at Jabor for use by Trust Territory personnel in accordance with an agreement between the AEC and Trust Territory authorities. In early March 1955, the scope of work involved with scientific stations and other facilities needed in support of these stations was de- lineated sufficiently to permit planning camps, locating sites for aggregate quarries and concrete batching plants, establishing material stockpiles of construction items, and projecting manpower, equipment, and marine craft requirements. This planning contemplated those problems that are characteristic of operations at the PPG. The need for flexibility in plans was essential because of the program changes that would inevitably occur. These changes in scope of work, combined with budgetary requirements and limited transportation, called for careful checks and balances to assure adequate anticipation of manpower, equipment, and materials. Because the extent of work ultimately far exceeded the original scope, hurried increases in manpower, equipment, and construction ma- terials had to be effected late in the construction phase of the Operation. Construction of 200-man camps at Yvonne and Ursula was authorized on 15 April 1955, a 125-man camp was authorized at Fox on 30 April, and 200-man camps were authorized at Tare and Gene on 9 June 1955. The construction of these shot-island camps was routine and followed along well-established lines. Figure 2-15. Bulkhead Construction From April 1955 until early October 1955, the construction force was primarily engaged in work on these camps and other temporary base facilities needed in connection with the scientific test program. The airstrips at Elmer, Yvonne, Ursula, and Janet were placed in operable condition, and the causeways linking DogCharlie, Ruby-Sally, Gene-Irene and Sugar-Tare were reconstructed. An LST ramp and mole was built at Nan and the facilities at all sites for landing men and materials by marine craft, were improved or rebuilt. In August, funds were made available for construction of the ware houses, shops, and the Administration-Opera tions building as well as the expansion of POL facilities at Fred; construction on several cf these structures was started in September 195! On 9 September, the first mission for the estat lishment of weather stations departed Elmer for Kapingamarangi. During this period very little could be a complished with respect to scientific structures because criteria had not been firmed sufficiently to permit release of drawings, with the res ; that by 15 October construction progress 1 this phase was estimated to be only 2 per cent complete. In early October, drawings were re- ceived and work was started on the construct’ 3 of three man-madeislands on the Dog-Cha e reef, two causeways and an island off Yvonue, and a causeway off Sally, all of which were required in connection with scientific proje ‘s. About this time work was also started on ba: 2s to be used as zero stations and on tower aud guy anchor footings for zero towers. Shortly thereafter, working drawings for the var wu Figure 2-14.
