During the operational phase, the off-atoll projects were supported by both land and seaplanes. were not well charted; the depths were irregular, thereby making boat operations hazardous. Information on the condition of beaches for landing LST-type craft was particularly lacking. Reconnaissance in advance of each mission was necessary to determine how and where construction materials could be landed. Masters of the supporting vessels had to exercise extreme caution in navigating these waters and in landing construction materials. Air support for emergencies and mail during the construction phase was by seaplane; the only available airfield on COSTS. The monthly accrual of the estimated and actual commitmentof funds and actual expenditures are shown in Chart 1-2.

PROGRAMING. The engineering-construction tasks connected with test facilities for REDWING, when first outlined to the Contractor in March and April 1955, were delineated only in broad terms. The missing factors had to be anticipated and evaluated in order that a realistic approach to the problems involved could be made. From the experience gained through planning and executing the tasks involved in three previous Test Operations, evaluations were made of manpower, plant, equipment, materials, and camp and other services. With these factors established, a budPage 1-8 Program Costs get analysis was made and a forecast of funds required was furnished the Atomic Energy Com- mission. As the scope of work and criteria be- came more clearly defined, the entire construction program was projected on an Estimated Operations Schedule, which programed each item of work from design through procurement, to the completed structure ready for occupancy. The manpower forecasts were developed to provide for a build-up of Jobsite personnel in phase with the planned availability of working drawings and materials, and within budgetary limitations. The original forecast, based on con-
