CHAPTER I, SECTION 1 accelerated delivery of construction materials called for more frequent sailings as there was more cargo to be shipped than originally anticipated, and there was a recurrent need to ship certain items as early as possible. A revised schedule was then effected for the period of peak shipping which provided more frequent sailing. Contractor representatives were stationed at NSC to check and supervise all incoming cargo and to coordinate all outgoing cargo with the JTF-7 Transportation Liaison Officer. Even though a close working relation- ship existed, certain difficulties developed, which were unanticipated and which, because of the crash nature of the construction program, re- sulted in serious dislocations in the orderly progress of construction. The loading and departure times of vessels were subject toe changes, and there were instances of urgently needed cargo deferred to later carriers. The availability of certain materials and equipment became the vital factor in on-site construction scheduling. Overseas air transportation was provided by the Military Air Transport System with the on-continent terminal located at Travis Air Force Base. With the need for accelerated delivery of materials, a considerable amount of cargo had to be diverted from surface to air transportation. The only items airshipped were those the urgency of which was so great that to hold them for surface transportation would seriously affect construction schedules. Initially, space requirements were estimated four months in advance as required by Task Force Operating Procedures. However, as the amount of cargo that became critical kept increasing, the esti- mates for space had to be changed to a monthto-month basis. The demands on MATS from all agencies in the operation became heavy and subject to radical variations. During September, October, and November 1955, the Contractor's cargo could not be lifted in accordance with allocations, and backlogs of urgently needed cargo developed.
