“ie expansion during operational periods. During a test series buildup and operations, other support camp facilities are provided in the firing areas on other islands. As of July 1953, construction was in progress on such facilities at several locations on Bikini Atoll. Sandia Community This supporting community, located on Sandia Base and in effect a joint AEC-AFSWP effort, has been an important factor in the growth of Sandia Laboratory, Construction of facilities by the AEC at Sandia started in the winter of 1947-1948, with the Corps of Engineers acting as AEC's authorized representative. The first contract was for erection of temporary housing for AEC and operating contractor employees. This housing was constructed on military land with the understanding that as soon as other AEC housing was available it would be turned back to AFSWP. The Corps of Engineers continued to supervise all AEC-Sandia construction, community or technical, until July 1950, when responsibility was assigned to the Sandia Field Office. The community construction program was begun and largely completed during the pre- vious three-year period at a total cost of approximately $5, 935,000. Included were housing (235 single units, 136 apartments, and 100 dormitory rooms), and the Coronado Club for recreation, Since mid-1950, 30 additional housing units for single occupancy, second phase landscaping, and some street and utility construction has been completed, at a cost of $998, 000. An additional total of $6, 421, 000 of AEC funds was turned over to AFSWP for construction of community facilities, some of which were joint projects with AEC. In the period prior to June 30, 1950, the AEC housing area was administered by AECSandia through a housing office which controlled occupancy, collected rentals, utility pay- ments, and generally supervised operations in the area. By agreement with AFSWP, hous- ing maintenance was performed by the Post Engineer, AFSWP, on request of the AEC Hous- ing Office, In the Spring of 1950, the AEC Housing Office was disbanded, and operation and maintenance of the housing area was turned over to Sandia Corporation, the operating contractor for Sandia Laboratory, In addition to the AEC housing on Sandia Base, AFSWP has a large housing area which has approximately two and one-half times more units than that of AEC. In 1951 there was completed adjacent to the Base a Wherry Housing Area which was a joint project between USAF SWC, Kirtland Field, and AFSWP, Sandia, with a provision that AEC personnel or Sandia Corporation would have access to a limited number of units in this area if needed, and if available after military requirements had been fulfilled. Effective August 1, 1953, and in conformance with the requirements of the Bureau of the Budget Circular A-45, average rentals were increased by approximately 33.5 per cent.
