Guidance from job tag (Japanese)
仕事は小規模な土質調査から石油・ガス掘削のような大規模な工事まであり、会社も石油や井戸の掘削会社、ボーリング部門を持つ調査コンサルタント会社、土質調査会社等に大きく分類できる。
入社後のキャリアアップは助手→機長→現場責任者→主任技術者のステップを踏むが、ステップアップに要する年数は仕事の内容によって異なってくる。一般に機長になるには数年を要する。一般の調査工事では、機長は地質調査技士の資格が必要な場合が多い。主任技術者では「技術士（応用理学部門）」の資格が問われる場合がある。関連資格として厚生労働省の定める「さく井技能士」がある。
独立開業しやすいのは、機械や工事規模の小さい土質調査関係であり、調査コンサルティング会社の下請をする場合が多い。
厳しい作業環境、勤務形態（交替制）、長期出張等があることから体力と精神力、それに共同作業への適応性等が求められる。
