PART Ill, CHAPTER 4 Figure 3-5. 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 204-Communications; a threefingered barge slip and assembly area; and Assembly Building 279. The rehabilitation and modification of Stations 70 and 500 also required considerable construction effort. In addition to the manyscientific structures, complex submarine cable and electrical distribution systems were installed at Eniwetok and Bikini Atolls to service the various major installations. Several existing stations at both atolls were modified to meet the requirements of Operation HARDTACK,Phase I. test facilities on schedule. The late submission of criteria to the Contractor resulted in a “crash” construction program to meet 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 Page 446 Additional events were scheduléd early in June and absorbed into the construction program. The problems of emergency procurement were met by “crash” buying in the United States and in the Hawaiian Islands, and by the expediting of items by air to Jobsite. Construction starting and completion dates for scientific stations are shown in Fig. 3-7. 4.8 4.9 (W-882-2) Station 1312, Site Janet. 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 Operation HARDTACK,the majority of mechanical equipmentinstalled in stations remained in place, with the provision that the equipment be opera- ted every two weeks for maintenance purposes. »>?eqoe@qeeoaoqeoaeonnma@wq@qeqeeeweenanaaananananaaean anaaanee me a ee me ieeeeth 6 teen eeatten Te
