Hello, everyone.

This is Enta.

The other day, I was talking with the president of a certain company.

That company primarily works as a subcontractor for major firms.

The problem was that the major companies were being overly pushy about their unit prices.

First of all, it seems the quote won't be approved. Also, it seems the unit price will be set at a fixed rate.

There's no point in getting an estimate, is there?

Apparently, since the president is still young, he can’t bring himself to refuse when ordered by his superiors, but it was just too outrageous.

And apparently, that pushy employee is highly regarded by the company (because he generates profits), and he’s said to be hoping to climb the corporate ladder.

Since I'm a corporate employee, I think it's a very good thing to aspire to a promotion.

I think that as you move up the ranks, your salary will increase, and you’ll be able to manage your work to some extent based on your own judgment.

But if you climb the corporate ladder by relentlessly squeezing your subcontractors, you’re bound to get your comeuppance eventually, aren’t you?

I used to be a salaryman, too. I never really wanted to climb the corporate ladder, lol.

There was someone like that. But in the end, that person failed, didn't they?

In the end, those who try to get ahead by stepping on others will end up being stepped on themselves.

Even the subcontractors won't go along with that.

Ultimately, the people who get promoted at major companies areA nice personThat's it!(Of course I can do the job!)

That’s exactly why the construction company is willing to work with him, isn’t it?

 

And usually, those kinds of people who try to knock others down say something like this:

Like, "Once I get promoted, I'll bring you up with me"... lol

But that's beside the point.

Choosing the Right Type of Cement

Do you use different types of cement slurry in summer and winter?Are you doing that?

I do vary my approach slightly, depending on the timing and project schedule.

1. When there is no construction schedule = Rapid-setting cement

2. When there is a construction schedule = Ordinary cement (e.g., reverse-wrap method)

3. Cold Weather = Early-Strength Cement

4. When it's hot = Regular cement (has a margin of safety for tensile strength testing)

5. When the injection distance is long = ordinary cement

6. When the injection distance is short = Either way

That's the gist of it.

The general perception is that when there’s a tight schedule, it’s hot, and the distance is long, cement is usually the go-to choice.

When mixed with ordinary cement, the milk concentration is lower, so the flow rate increases.

That means it's suitable for long distances.

When used in cold weather, fast-setting cement hardens quickly due to its high heat of hydration, resulting in early strength.

Furthermore, fast-setting cement generally has low workability and a slow flow rate.

Naturally, the injection costs will go up.

Cement costs will rise by about 20 percent, but

The construction period from the start of grouting work to the start of service will be significantly shortened to nearly half.

I think you'll immediately see which is more cost-effective when you compare the labor costs to the cement costs.

 

See you later.
