CHAPTER I, SECTIONS 2-3-4 work was expanded, increased costs were reflected in actual commitments. In November, with the work load stabilized, the estimated commitments were revaluated for the balance of the Operation. It was not necessary to slow down or to accelerate construction work. It will be noted in Chart 2-3 that a constant rate of progress was maintained from 15 September 1953 until 1 February 1954. Surplus manpower, when it occurred, was utilized in the permanent construction program, Projects 3028 and 4015. The rate of progress, to some extent, may likewise he determined by the yardage of concrete poured. As shown in Charts 2-5 and 2-6, a constant rate of pouring was maintained from 1 September to 1 December. The increase noted for April and Mayat Eniwetok was due to additional authorized items of work, as exampl:, Item A-74-C, Sea-Wall at Fred. SECTION 3 PERMANENT CONSTRUCTION Permanent constructionis listed under Budget Projects 3028 and 4015. The cut-off date for reporting permanent construction is dependant upon the date the project is completed and does not necessarily coincide with the completion date of the scientific construction. At the commencement of OPERATION CASTLE (1 January 1953), Project 3028 was 79.08% completed. At the cut-off date for OPERATION CASTLE (15 May 1954), Project 4015 was 86.74% com e:ed. These budget projects are reported upc.. the completion of each budget project and include final cost data. A large percentage of this permanent construction was required due to increases in operational population at both Elmer and Fred. Additional barracks, mess hall additions, laundry additions, additional sewers, waterfacilities, electrical facilities, communications faciliti.s, were included. Additional warehouses, shop additions, and fifty-three miscellaneous permanent con- Struction items were likewise required. The majority of this work was accomplished concurrently with the test program. SECTION 4 EXPENDABLE CONSTRUCTION FOREWARD This scctisn comprises all exnendable construction and is reported in numerical sequence of the contract item number, with the following exceptions: Contract Item Number Description Reported in A-26 Causewave Chap. 2, Sec. 6 A-27 Scientific Structures Chap. 2, Sec. 5 A-29 Interisland Cables Chap. 2, Sec. 7 CONTRACT ITEM NUMBERS A-1 THRU A-24 - TARE CAMP GENERAL. The Tare Camp was started in October 1952. A temporary beachhead was established and facilities were laid out for a 250- man camp. This included a pier and an LST landing ramp. Figure 2-35 notes the progress in construction by February 1953. The original beachhead camp is shown on the extreme right. Figure 2-36 shows the pier under construction in February. Teniative approval was obtained in January 1953 to use the Tare Camp as a base for the Bikini Operations with smaller outlying construction camps at other sites on the atoll as required. At that time it was esti- mated that facilities for 1000 men would be required at site Tare. On 18 Februarv autherization was received for the layout of this 1000man camp, and design work, including supporting facilities, was started by Field Engineering. On 16 March construction was authorized. On 27 March, authority was granted to requistion standard basic materials in order to expand the camp to 1500 men. Figure 2-37 notes construction progress as of 7 April. Figure 2-38 shows the enlarged Mess Hall as 91% completed on 10 June and Figure 2-39 shows the car. p area and construction progress by 11 June. Figure 2-40 shows tl exterior of the completed Chapel. Plans for an ultimate potential expansion to 1500 m-n were prepared in June in case the operation might require that population.
