道路の建設、河川の治水、土地造成などの土木工事の中には、大型建設機械では対応できない細部の作業や多種少量で機械化が困難な諸作業など、人力で行うことが不可欠な作業があり、このような作業を行うのが建設・土木作業員である。
 主として小型の重機械やベルトコンベア、軽量の削岩機などを使って行う掘削や盛土、コンクリートポンプやシュートを使うコンクリートの打ち込みと締め固め、また、一輪車を使ってブロックや石を運び、それを積む作業、芝張りなどの作業の他、重機械作業や鉄筋型枠組み立て、くい打ち作業等に伴う補助作業を行う。
 作業方法や作業手順、機械工具や資材の取扱い、安全衛生などについての具体的な指導は、直接指示命令をする作業長(世話役)が行い、雇用責任者や土木技術者は、専門的な工事施工上の知識や関係法令について指示・命令を行う。
 現場に入ると、仕事を始める前に、土木技術者や作業長から仕事内容の説明を受け、作業中は主に作業長又は作業指揮者の監督指示の下に作業を行う。

How AI is changing this job

A written analysis for this occupation is being prepared.

AI replacement risk compares the parts of a job that are easy to hand to AI or software (processing information, documentation, repetitive computer work) with the parts that are hard to automate (physical work, working closely with people, judgment in unpredictable settings), using the MHLW job tag survey on work activities, work context, skills and knowledge. The result is a relative position among all occupations in the country, scaled to 0–100%. Methodology →

How to become 建設・土木作業員

The typical path in Japan is shown by the education, training and experience of current workers above and in the Japanese guidance below. A detailed English guide for this occupation is being prepared.

Guidance from job tag (Japanese)
入職にあたって、特に学歴や資格は必要とされない。
 入職経路には、中学・高校等を卒業してそのまま入職する場合と、他の産業からの転職のほか、農閑期などで季節労働者となって働く場合など、多様である。
 就労前には安全確保の観点から工事の内容、会社の規則、作業場における規律や危険区域に関する事前教育を受ける。高度な技能を要する作業にはその内容に応じた資格が求められ、軽量ブルドーザーや小型クレーンを運転するには特別教育を受ける必要がある。ガス溶接や玉掛作業を行う場合には一定の技能講習を修了しなければならない。
 立ち作業、かがみ作業、単純作業、反復作業の連続なので、体力と持久力が求められる。共同で行う作業も多く協調性も求められる。
 作業環境によっては危険な要素も出てくるので、それらを未然に防止して快適に働くために、注意力、集中力も必要となる。
 建設・土木作業員の研修は、建設業労働災害防止協会などが主催して労働安全衛生法に基づく技能講習などが行われている。
 従事する現場に使用したことのない新しい機械が導入されたり、自分で運転する以外にも機械の近くで作業をすることが多いため、機械の機能についてある程度の知識が必要となる。
 普通自動車免許などを持っていれば、小型トラックによる材料の小運搬(現場の中での運搬など)に従事することができる。
 仕事の知識と経験を積み、指導力があれば、作業現場の第一線指揮者である作業長(世話役とも呼ばれる)になることができる。
 作業長に昇進するために義務づけられている資格は特にないが、土木施工管理技士、地山の掘削及び土止め支保作業主任者、玉掛技能者などの資格を取得している人もいる。しかし、作業長に求められる一番の要素は、作業を安全かつ円滑に進行するために必要な作業管理能力、後進を指導するために必要な技能と指導力である。
