programs, particularly those of the scientific structures and instru- mentation, neared completion, activity was centered on securing all remaining items of materials and equipment required for the experiments. The re-scheduling of construction work that had been necessitated by the delays incurred dur.ng the period when shipping space was unavailable resulted in certain equipment and material being in such vital need at this time that it became necessary to request increased airlift allotments. Figure 13.3-1, showing the extent of airlift shipments, graphically illustrates the situation. At this time H & N air freight was routed through the Naval Supply Center for transshipment to the Travis Air Force Base which served as the port of embarkation for Jobsite shipments. Approval was later abtained to consign all shipments directly to Travis Air Force Base and to station an H & N expeditor at the Base. The Procurement Department had a major part in the preparation of procedures designed to provide controls and facilitate the flow of air freight. The procedures are presented in connection with "Logistics" section of this Completion Report. By means of intensive expediting during the final months prior to the experiments, all essential materials and equipment were on hand at the Jobsite in time to fulfill requirements for the tests to be conducted as scheduled. It was during this period that the experience which had been gained and the procedures which had been perfe¢ted through the two years of procurement activity paid their dividends. From the time prior to the experiments to July 1, 1951, procurement operations declined sharply with resultant reductions in facilities and personnel. The scope of these later activities was confined largely to the provision of subsistence and maintenance supplies for Jobsite personnel and the procurement of materials for use in the roll-up operations. Figure 13.3-2 presents an over-all picture of procurement personnel, requisitions, and commitments throughout the Project fram February 1949 to July 1, 1951. 13-21
