PART Hil, CHAPTER 4 Figure 3-5. Station 1312, Site Janet. rebuilt at the new location. On Site Nan, the base camp for Bikini Atoll. the major facilities constructed included a TG 7.1 Administration Building: Building 20+-Communications; a three- fingered barge slip and assembly area; and Assembly Building 279. The rehabilitation and modification of Stations 70 and 500 also required considerable construction effort. 4.8 trical test facilities on schedule. Additional] events were scheduled early in June and absorbed into the construction program. The problems of emergency procurement were met by “crash’’ buving in the United States and in the Hawaiian Islands, and by the expediting of items bywair to Jobsite. Construction starting and completion dates for scientific stations are shown in Fig. 3-7. In addition to the manyscientific structures. complex submarine cable and elec- distribution svster.s were installed at Eniwetok and Bikini Atolls to service the vari- ous major installations. Several existing stations at both atolls were modified to meet the requirements of Operation HARDTACK, PhaseI. 4.9 The late submission of criteria to the Contractor resulted in a “crash” construction program to mt target dates for scheduled events. Use of shot barges for the majority of events provided a flexibility of location and at the same time allowed maximum utilization of the scientific complexes. Construction forces were working on a 72-hour extended work-week from March through July in order to complete (W-882-2) MAINTENANCE 4.10 Prior to the build-up phase of Operation HARDTACK, maintenance on scientific structures was continuous, with records kept reflecting the maintenance checks for each of the stations. Maintenance Work Orders were issued for the rehabilitation of certain of these stations during the build-up period. The interiors of such stations were cleaned or sandblasted and painted and, in some cases, the blast doors required extensive repair work. Following Oper- ation HARDTACK, the majority of mechanical equipment installed in stations remained in place, with the provision that the equipment be opera- ted every two weeks for maintenance purposes.
