Engineering aide (abbreviated as EA) is a United States Navy occupational rating. Engineering aides plan, supervise and perform tasks required in construction surveying, construction drafting, planning and estimating and quality control; prepare progress reports, time records, construction schedules and material and labor estimates; establish/operate a basic quality control system for testing soils, concrete and bituminous materials; prepare, edit and reproduce construction drawings; make control surveys, performing such tasks as running and closing traverses, staking out for excavations and obtaining and converting field notes into topographic maps; maintain individual combat readiness and perform tasks required in combat and disaster preparedness or recovery operations. The engineering aide's rating insignia shows a Philadelphia Rod, and alludes to the rating's original job, which was conducting surveys. At the master chief petty officer level, engineering aide merges with the builder and steelworker ratings. At this level, they are referred to as a master chief constructionman (CUCM). ==References== 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「engineering aide」の詳細全文を読む スポンサード リンク
