What 解体工 do
An English description is being prepared. Japanese description:
取り壊しに当たっては、先ず対象となるビルなどを調べ、取り壊しの方法や手順などを決定し、足場を組みシートなどでビルを覆って、破片などが周囲に飛び散るのを防止するなどの準備作業を行う。
次に、工事の計画書にしたがって本格的な取り壊し・撤去作業を行う。その際、環境面にも配慮し水をかけて粉塵が飛ばないように注意しながら作業し、建物の土台部分までを取り壊していく。なお、以前は機械で一気に壊す（ミンチ解体）ということもあったが、現在は特定の建設廃棄物資材は有効に利用することが求められているので、大型機械を用いる場合でも分別を考えて作業する。
最後に、コンクリート、鉄、木材などを分別して収集する。その後トラック等で運び出し、更地にして引き渡す。工事期間を守り、安全に施工することが必要である。
また、建設リサイクル法の制定以降も、解体工事に関する規制は強化される傾向にあり、情報をきちんと入手し、正しく作業を行うことが求められている。
◇ よく使う道具、機材、情報技術等
トラック、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 解体工? 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 解体工
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.
