What 鉄筋工 do
An English description is being prepared. Japanese description:
鉄筋コンクリートは、構造物の中でもよく使われている構造体で、建物の骨にあたる鉄筋部分の施工、加工、組立作業を行うのが鉄筋工である。作業現場は、マンションやビルなどの建築物をはじめ、橋げた、トンネル、高速道路、地下鉄にいたるまで、人が生活するあらゆる場所に及んでいる。
仕事は施工図・加工帳の作成、加工、組立に分かれる。作業手順は、まず、作業を行う構造物の図面を見て、使用する鉄筋のサイズや形状・本数を拾い出し、加工帳を作成する。次に、鉄筋業者の工場で加工帳にしたがって適切な寸法に切断、曲げ、加工された材料を現場で組み立てる。基礎、柱、壁、床、階段といった部分や位置ごとに、図面と配筋基準どおりに取り付けていく。
安定した丈夫な構造物を造るために重要な仕事であり、正しく選別・加工された材料を使って、基準に沿った取付けを行う必要がある。
◇ よく使う道具、機材、情報技術等
工具（かなづち、のこぎり等の手動工具、ドリル等の電動工具）、作業中の保護具（ヘルメット、ゴーグル、グローブ、安全靴等）

What drives the annual growth rate
Projected pay = current pay × (1 + annual growth)^years. The annual growth rate starts from a base wage-growth rate and adds or subtracts labor demand (the job-openings-to-applicants ratio), wage momentum and AI replacement risk for each occupation. Projections are not guarantees. How it is calculated →

Will AI replace 鉄筋工? AI replacement risk
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 →
Labor demand for 鉄筋工
A ratio above 1.0 means there are more job openings than applicants (a labor shortage). The 5- and 10-year figures are estimates from the openings ratio, wage momentum and AI replacement risk.
