“ t NA CHAPTER Ii, SECTIONS 1A-1B tific Stations and ranges established for the post- blast survey of the Station 20 were accepted by the Scientific Group. Station 10 was moved into the Flora crater, and its position and movement checked by the same procedures used for Station 30. Due to the late scheduling for moving this station to the Flora crater, it was not possible to re-establish precise control in the area by expansion from the primary network. However, satisfactory local control established during OPERATION IVY was recovered and assured the positioning of the barge to required tolerances. SECTION 18 TESTS AND INSPECTION GENERAL Operating as a part of the Engineering Division, the Test and Inspection Department, under the suzervision of a principal engineer, was divided into two distinct sections - Field Inspection and Materials Testing. The primary function of the Field Inspection Section was to assure that a!l work performed and alli materials used complied with the approved plans and specifications.

The Ma- terial Testing Laboratory on Elmer was used as headquarters for the Test Section with a branch base for the Bikini Atoll located on Tare. The bulk of the work consisted in obtaining samples and testing construction materials such as cement, aggregates, concrete mixes and as-
