What 型枠大工 do
An English description is being prepared. Japanese description:
ビル建設にとどまらず、土木工事でも新幹線、橋、トンネル、地下鉄などコンクリートを使う工事は全て鋳型となる型枠が必要である。
仕事の種類・規模は様々であるが、鉄筋コンクリートの建物を例にとると、まず、合板（コンパネ）を主材の型枠板として施工図に合わせて各部のパネルを作成し、締付金物で固定する。
鉄筋工が組み立てた柱となる鉄筋の周囲をパネルで囲み、壁の内側を先に立て、柱上に梁（はり）を架け、スラブ（床）を連結し、梁と床を固定する。次に壁の外側を立て、内外壁を金具で締めつけ、最後に水平垂直をチェックし、型枠検査を受けて型枠が完成する。
コンクリートを流し込む際は、型枠が壊れないよう監視を行い、流し込んだコンクリートが固まったら、型枠を取りはずす。この作業は、大規模な工事の場合は解体工事を専門に行う型枠解体工が行うこともあるが、小さな工事の場合には型枠大工が行う。
◇ よく使う道具、機材、情報技術等
杭、鉄筋、型枠板、締付金物、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）

Today ¥4.15M → in 3 years ¥4.52M → in 5 years ¥4.80M → in 10 years ¥5.55M (10-year range ¥4.77M–¥6.44M). The model assumes pay growth of +3.0% per year.
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 型枠大工? 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 型枠大工
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.
