施工単価の決め方、単価の作り方(一般向け)
皆さんこんにちは。 エンタです。 先日ある呑み会で単価の出し方の話になりました。 他業種の方なんですが、基本的に単価の出し方って同じなんです。 なので、法面屋としての出し方も土工事の出し方も基本は同じなので解説してみようと思います。 &nb…
With the number of contractors holding construction licenses steadily declining, will licenses eventually become unnecessary?
Hello, everyone. This is Enta. I’ve been in Tokyo for the past few days, attending on-site meetings. During one of them, someone asked, “Aren’t there any stonemasons left these days?” lol. The reason is that the job we’re working on involves splitting massive boulders. They want us to split these huge rocks. Usually, our slope work…
生活の中にも力学｜座屈と単管足場の受圧面積を考える
皆さんこんにちは。 エンタです。 今日は座屈と言う言葉を考えて見たいと思います。 座屈。 知っていますか？ 座屈（ざくつ、buckling）は、構造物に加える荷重を次第に増加すると、ある荷重で急に変形の模様が変化し、大きなたわみを生ずること…
Understanding Connections from a Three-Phase 200V Capacitor
Hello, everyone. This is Enta. The other day, I installed a power supply for the winch. Since it’s three-phase 200V, there are four wires: three phase wires and one ground wire. If you don’t connect these properly, the polarity might reverse or the winch might not deliver any power. This can actually cause some unexpected problems on site, so…
Let's take it easy after Obon and aim to stay injury-free!
Hello, everyone. It’s Enta here. The other day, I went for a run on Mt. Kinka lol. I thought it would be a piece of cake, but the course started with a steep climb of about 650 meters, and it was absolute hell. Man, I never thought I’d end up in the mountains for anything other than work lol. Mission accomplished…
There’s absolutely no way my craftsmanship has gotten worse since yesterday!
Hello, everyone. This is Enta. Has the Obon holiday ended for you yet? Is today your first day back at work? It varies from person to person here. Or rather, it depends on the worksite. For those starting work today, don’t push yourself too hard—just take it easy. There’s no point in getting injured on the very first day. But anyway…
On a typhoon day like today, the golden rule is to stay home and take your time doing something—and definitely don’t go outside!
Hello, everyone. This is Enta. It’s the Obon holiday—how are you all doing? As usual, I’ve been making the rounds at the office, then coming home to zone out a bit, take a nap, and get some work done. Since we’ve had a lot of private-sector construction projects lately, I’ve been reading books like this. …
Construction workers are ranked number one on the list of the lowest-status jobs, but civil engineering is the best!
Hello, everyone. This is Enta. Construction workers have recently been ranked number one on a list of “lowest-status jobs” that’s been trending online. What do you all think about that? After all, from other people’s perspective, our work is seen as dirty work, isn’t it? Even if they call it a “lowest-status” job, well…
Maybe all a middle-aged man needs is a few friends and some hobbies.
Hello, everyone. It’s Enta. The other day, I did a little work in Tokyo, but the rest of the time was just for fun lol. I went shopping with some senior colleagues from my old office days and had cake sets at cafes lol. A bunch of guys around 50 lol. Getting together like this with old seniors and juniors…
