Requirements During Construction. It was contemplated in the Recon- naissance Report (see Page IV-95) that construction forces initially housed at Eniwetok in small numbers and later based on Parry would require power for their operations prior to the completion of the final plants. To this end a survey was made and some low-voltage skid mounted Diesel generator units were located on Eniwetok. in suitable condition. These units required repairs to put then These repairs have been and are being made and these units are being used for this purpose. Several additional small units wil be used to supplement the ones obtained on “niwetok. ELECTRICAL POWFR DISTRIBUTION: Since a modification of the Many Small Plant scheme of power supply is being adopted as the power supply system for the operations, no inter-island power distribution is required (see Pages 1V-96 to IV-101 of the Report). Power Distribution on Islands. Overhead distribution will be provided on Parry and Eniwetok and for the construction camp portion of experiment islands. Underground distribution will be used for primary feeders as well as secondary feeders and branch circuits serving instrumentation loads on experiment islands (see Page IV-102 of Report). COMMUNICATIONS : The Proving Ground operation will require reliable communication between stations located on Parry, Eniwetok, Japtan, the experiment islands, the Photo Towers, and ships anchored in the lagoon. These needs are particularly vital during the period before each experiment. The Armed Forces will require the use of communication facilities on Eniwetok and the experiment islands for security personnel operations. Construction personnel will utilize communi- cations between the various islands during the construction period. In 2h.
