CHAPTER It, SECTION 1 veys, procurement of critical materials and equip- ment, and expeditious approval of preliminary plans. 22. Standard Specifications for Eniwetok Proving Ground, 1 October 1957 Blast Study Studies and Reports The following reports and studies were prepared during Operation HARDTACK: 1. Study of Vehicular Causeway Between Parry and Eniwetok Islands 2. Proposed New Holmes & Narver Office Building, Site Elmer 3. Study of Multi-Story Barracks, Eniwetok Proving Ground 4, Recommendations for Disposal System of Wet Garbage, Eniwetok Proving Ground The Blast Study Group participated in Operation HARDTACK as part of a general program for the development of information leading to the improvement of the design of AEC test structures. This objective was met 1) by obtaining reports of nuclear test results, laboratory test results, studies of nuclear weapons effects, and development of blast-resistant design procedures and design manuals; 2) by liaison with other agencies having related interests to obtain current information being developed by tests and investigations; and 3) by participating in nuclear tests when necessary to develop specific information for AEC needs after a careful check by liaison with other agencies to assure that such 5.

With the above objectives liaison was maintained with the following agencies: HQ/AFSWP, FC/AESWP, OCE, BuDocks, AFSWC, Sandia, WES, SIO, and BRL. The observation of damage to test structures at both the Nevada Test Site and Eniwetok Proving Ground on a continuing basis is an imteria. While the damage surveys have been con- condition of stations with respect to their use for the next Operation, such damage reports were not directed toward assessing the adequacy of design. The purpose of the Blast Study Group in planning for participation in Operation HARDTACK wasto select structures in advance which would be likely to suffer damage, then measure or obtain from others the overpressures and other effects to which they were subjected and observe the damage in relation to such exposure. It developed that Headquarters AFSWP, realizing that much useful information could be obtained from the observation of damage to structures exposed to blast as a result of the test operations, had planned a similar project. Accordingly a a joint AEC-AFSWP-sponsored project was established. Military participation was provided by the U.S. Waterways Experiment Station, Vicksburg, Mississippi, a laboratory of the Corps of Engineers, U.S. Army. The AEC participation was accomplished through H&N. The WESprovided a Project Officer and an assistant, surveying equipment, and measurements of over- pressures and accelerations of structures. H&N provided an Assistant Project Officer, informa- tion on structural design of stations, measurements of wave heights and inundations, and general support.
