Hello, everyone.

This is Enta.

What is the standard overlap length for rebar?

 

If someone asked me that, I think I'd say, "It's a 35D, right?"

So where exactly is that "35D" written?

If someone asked you that, could you answer?

 

As those in the know are surely aware,

It is featured in a publication by the "National Association for the Protection of Specified Slopes."

I think that's the answer.

If someone asks, “What about NEXCO? What about the Ministry of Land, Infrastructure, Transport and Tourism?” can you confidently say, “It’s listed there!”?

A long time ago, the Ministry of Land, Infrastructure, Transport and Tourism listed "40D" in the Yellow Book, or

There were some regions where "45D" was listed in the special specifications.

"What area is 45D in?" and so on

 

These days, prices are basically based on market rates, so loss rates don't really matter—you don't even need to know them—but,

In the past, all these detailed specifications were included in the technical specifications.

A lot of the things I wondered about were actually in the book.

 

However, even such explanations have been simplified these days, and it seems to me that more and more people are unaware of the essence of the matter.

"That's how we did it at the ○○ site, so we're doing it this way."

That was the only flippant answer I got, and,

I feel that the true essence of experience-based civil engineering—the kind that has been accumulated over time—is gradually being lost.

As an engineer, I think it’s definitely better to have it easy.

Precisely because we are in a transitional period between analog and digital—an era that is already complicated in many ways—

I suppose civil engineering could be simplified to some extent, but can it really be called “experiential engineering” without understanding its essence?

I’ve been thinking about this a lot lately—I wonder what’s going to happen from here on out?

Even if people were to move in simply to improve the image of civil engineering,

I am concerned that a superficial, hollow civil engineering project is taking shape.

 

That is precisely why I hope that, even if it’s just within our own company, we can pass down these true technologies and skills.

Just regarding the slope, though ^^

 

How about your company?

What is the skill level of the engineers?

What about you, including yourself?

The other day, I was talking with a senior colleague at a major general contractor, and the conversation turned to that topic.

 

It was a day that really made me think.

 

See you later
