@kojikojikodayo 私の身近な人の例ですと、私はいつも“できる理由”を探すのに対して、当人は“できない理由”を探しているように感じます。率直に、人生でそれ以上無駄なことはないと感じていますが、他人の性格を変えることは難しいですから、なんとももどかしく思います。

@tkyuki10 おっしゃる通り、先手先手で動くことが本当に大事だと感じます。最近は現場を数日離れる場合には、残る人に「出来ることリスト」を書いて渡すようにしてます。戻って来てからイライラしてしまいますので…汗

ここ最近「作業を前倒しする能力」が重要だと感じます。なぜなら、後の作業工数を減らせるだけでなく作業量を均一化できるからです。例えば、“まだ配管できない”状況でも、支持金物を取付けたり墨出しや加工をしたり。余裕がある時でも、できる作業を見つける力が無い人の現場は必ず尻に火がつきます。

ポリ管をコンクリート面にサドルで固定する場合、特に気をつけている事があります。それはビスやAピンの下穴をハンマードリルであける際、穿孔した後のキリがポリ管に接触しないようにすること。なぜなら熱でポリ管が溶けるからです。穿孔直後のキリは本当に熱いので火傷にも注意した方がいいですね。
