Box 5400 Albuquerque, New Mexico Subject: 30 January 1957 TAONGI ATOLL - CONSTRUCTION AND SUPPORT REQUIREMENTS Dear Mr. Sanders: se. This report covers the requirements for the construction of scientific and support facilities for an operation in Taongi Atoll. As a basis for this report a maximum and minimum requirement has been assumed. The maximum scope contemplates the construction of stations similar to Castle Stations 1210, 13he, 1550, Station 70 (Nan) with a 300 foot tower, the mooring of five scientific barges within the lagoon and the provision of camp and other support facilities. The minimum scope of work © assumed was the construction of a station similar to Station 70 (Nan), a 300 foot tower, the mooring of five barges within the lagoon and a minimumof camp and other support facilities. Accessibility of Taongi. There is no safe passage into the Atoll in its present state for landing craft. The study and appraisal of the construction requirements and the cost estimates have been predicated on being able to provide the needed access. From a study of charts, photographs and other information available it appears feasible to initially land equipment and materials on the southwestern reef at low tide. Wheeled or tractored vehicles might be landed at this point and then moved to dry land during the hours of low tide. From this initial undertaking we expect to construct operating islands along the route for the storage of equipment during periods unfavorable for working on the reef. The feasibility of the above approach can only be determined by an on-site survey. This survey would also determine the best location for an entrance channel which we propose to construct. Such a survey could also determine whether a suitable anchorage for supporting vessels exists to seaward of the Atoll. Camp Facilities. It is proposed to first establish a beachhead camp from which our activities might be expanded. The site location of the camps will be determined during the on-site preliminary survey that is expected will be made. It will be necessary to subsist and sustain the first group of construction personnel on the supporting vessel until the beachhead camp can be established. A 200-man camp of standard design (similar to Fox camp of Redwing) is proposed for maximum re- quirements. For the minimum requirements we contemplate either a 100-man camp ashore or a barge type barrack for both messing and housing. The costs provided hereinafter for camp facilities to support the minimum scope of work have been estimated to be the same for ashore or afloat operations. The camp facilities will be so ee that they may be expanded on an "as needed! basis. GET NRATION{CELEWUMRERS tho’ra.wore Con = pride tes ede ee iho. Willa 1.
