"Xia Gong, I think the problem may be in this place... ”

Li Huayong pointed to the "design change application report" in his hand, and turned to Xia Minghuan, the chief engineer of the project.

"Oh, Xiao Li, tell me about it. Xia Minghuan held his glasses and looked at Li Huayong.

Strictly speaking, the two have not known each other for a long time, and they have only had formal contact and dealings a few times. However, our Chief Engineer Xia didn't dare to underestimate Li Huayong at all.

Xia Minghuan is in his 30s this year, and because he has been working in the field for many years, he looks much older than his actual age. A rugged face, coupled with the bookish atmosphere of an intellectual, makes Chief Engineer Xia have a very unique temperament. In fact, many engineers who insist on the front line have a similar temperament.

Xia Minghuan is Lei Jianjun's old subordinate, and he, like Lei Jianjun, has just transferred from the army to the "Huaxia Construction General" not long ago. Xia Minghuan's respect for Li Huayong actually contained a considerable amount of politeness at the beginning, which was not only reminded by Lei Jianjun, but also because Xia Minghuan didn't know much about his new unit. "Huaxia Construction Corporation" has a great reputation in the industry and sits firmly in the first place in domestic civil construction.

Therefore, Xia Minghuan's respect for Li Huayong at the beginning was actually more of a respect for the "Huaxia Construction Association" than for Li Huayong himself.

Although he, like Lei Jianjun, also couldn't figure it out: why a random peasant contract worker from "Huaxia Jianzong" could be so good.

However, after a few contacts, after the two officially dealt with each other a few times, Xia Minghuan changed from superficial respect to real respect. In the past few days, Li Huayong has been running diligently here, and the real business counterpart, and the person who is really responsible for the reception is actually the chief engineer of Xia Minghuan, the project.

In the process of dealing with Xia Minghuan, Li Huayong actually did not deliberately show off. However, the so-called connoisseur stretched out his hand to know if there was one. Li Huayong is from a technical background, in essence, he and Xia Minghuan are real peers, peers among peers. Li Huayong is an expert in the construction industry, and Xia Minghuan is of course another expert.

In fact, the communication between connoisseurs and connoisseurs does not need to be multi-language, let alone rhetoric. After Xia Minghuan came into contact with Li Huayong for the first time, he had the same impression of Li Huayong as Lei Jianjun: This person is extraordinary!

Wait until you have a few more contacts ... How can this be said? Xia Minghuan's impression of Li Huayong cannot be described only as "extraordinary," and Xia Minghuan's heart was full of all kinds of shock and shock.

This young man, nicknamed "Dunzi", is still a farmer contract worker. But he is always a calm look, he doesn't say much, but as long as he talks about construction problems, especially when it comes to construction technology problems, he is full of energy, he is shocked in a nutshell, and he can get to the point in a few words. He is even often able to answer a lot of his own confusion, and it must be pointed out that his answer is not the kind of deliberate answer, but so careless, as if he unintentionally revealed a few words, and he suddenly opened up.

In just a few contacts, our Chief Engineer Xia was obviously suppressed by our "Deputy Chief Engineer Li". Xia Minghuan had a feeling that the other party's skill level seemed to be above him. The chief engineer of a project is not as good as a peasant contract worker of the "Huaxia Construction General Manager"? This feeling made Xia Minghuan very uncomfortable.

But being uncomfortable is uncomfortable, which does not prevent Xia Minghuan from looking at Li Huayong with admiration, and even from preventing Xia Minghuan from respecting Li Huayong. The reason for this is very simple, at present, the status of the two is very different, and there is no interest involved. Not only do the two have no interests, but they even have the same interests in many places.

The second and most important point is because Xia Minghuan is an engineer, an engineer in the true sense of the word.

Now the whole project is in trouble, a design change report is stuck by the Japanese designer, if this design change cannot be passed, then the entire construction period will definitely be delayed. And if the construction period is delayed... This is Xia Minghuan's first project after coming to "Huaxia Construction Corporation", and more importantly, this project is still in Pengcheng, which is a Sino-foreign joint venture project and the first batch of Sino-foreign joint venture projects in China.

No one wants this kind of thing to happen, and as the technical leader of this project, Xia Minghuan is even more reluctant to have this kind of thing happen. But now Xia Minghuan has no clue at all, he doesn't know what went wrong with his application report, and he doesn't know why the designer is stuck with this report.

At this time, Li Huayong suddenly told him that he knew what the problem might be. This immediately attracted Xia Minghuan's attention, not only him, but also Lei Jianjun, the project manager, also set his sights on Li Huayong.

Facing the two eager eyes, Li Huayong sighed in his heart. After a few days of contact, he believes that whether it is Lei Jianjun, the project manager, or Xia Minghuan, the chief engineer of the project, they are actually very good builders. For example, Lei Jianjun is decisive and determined, which is the most important and basic quality of an excellent project manager. And Xia Minghuan is skilled in business and careful, which is also a very good project chief engineer.

But now they all have flaws, and of course they can't be blamed for such flaws. For example, in the project they are now responsible for, the owner and Party A are from Xiangjiang, the designer is Japanese, and I heard that the supervision party is also from Xiangjiang, and only the construction party is from the mainland. In the words of later generations, this is a standard international cooperation project, and what Lei Jianjun lacks at present is a little bit of international vision.

The construction process of manual digging pile, it itself does not have much technical at all, compared with mechanical holes, this construction process is also difficult to call efficient, and its biggest benefit is actually the flexibility of this method.

Flexibility is a good thing, it is precisely because of such an advantage of manual digging piles, so even after 30 years, this construction method has been widely used in China, and it can be seen everywhere in the domestic construction market, and everyone is used to it.

But a very interesting thing: although the artificial digging pile can be seen everywhere in the country, but it is difficult to see it after going abroad, whether it is a developed country, or those who are poorer and more backward than China in this era, it is difficult to see this construction technology.

What is the reason for this? I talked about the advantages and advantages of manually digging piles, since this construction method is not adopted in large quantities, it is natural to start from the shortcomings of this construction method.

The disadvantage of manually dug piles is obvious, that is, its unsafeness!

A hole with a diameter of just over one meter is as deep as a dozen meters or even tens of meters. Landslides, groundwater, quicksand, dark rivers... Let's not talk about these complex geological structures, just imagine the weather in Pengcheng in July and August, one or two workers, in such a small platform, the mud under the ground is packed out buckets and barrels...

The hard work of the workers can be imagined, and the danger of this kind of work is also obvious. Even ordinary people can think that there is actually a little bit of this method of operation... Inhumane. Isn't modern society paying more and more attention to the protection of workers' rights and interests? Isn't it becoming more and more stressful about "human rights"? This is the reason why it is rare to see manually dug piles in developed countries.

Of course, "talking about human rights" is only a matter of developed countries, so why do those underdeveloped countries rarely see artificially dug piles? Really do not blow or black, such things as artificially dug piles, then only we Chinese can do well.

In later generations, as the country became stronger, the Chinese undertook a large number of projects overseas, and the design of many of them was also done by domestic design institutes. Domestic design institutes, of course, will consider the construction method of manual digging piles.

An interesting thing: as long as the manually dug pile is in China, then it is no problem to put it in any place, and the construction unit is also very happy to do this kind of work. But as long as they go abroad, the construction unit is unwilling. Manually digging piles is a purely manual work that requires a lot of labor.

The black uncles of Africa, the Asan of India, the monkeys of Southeast Asia, the savages of South America... If you let these people do the manual digging piles, then there is only one consequence, you can be by them. You mobilize workers from China to go overseas, but the construction period of pile foundation construction is generally short, hard to go far, people workers are not necessarily willing, and it is also a very troublesome thing to manage a large number of workers overseas, so even if Chinese construction companies encounter manual digging piles overseas, they will also suggest that the design unit modify the design and change the manual hole into a mechanical hole.

"Xiao Li, you mean to say that the designers are mainly concerned about the safety of the manually dug piles, which is why they are unwilling to make design changes, right?"

"Security is one aspect, it's a very important factor, but it's not decisive, it's another reason that matters. ”

"Oh, why?"

"Money! Changing the design involves the cost of the project, which is the main reason why the Japanese are unwilling to make design changes... ”

In the construction industry, the project cost is usually divided into two parts, which is the so-called "direct cost" and "indirect cost". Labor costs, machinery costs, material costs... These indispensable rigid expenses are called direct costs in the construction industry, while other expenses such as taxes, insurance, plan profits, various measures related to safety and quality management, and various administrative expenses are called indirect costs.

Let's not talk about indirect costs here, but mainly talk about direct costs, because in a building, direct costs generally account for the majority. The direct cost of a building basically determines the cost of the building.

Among the three major expenses included in the direct cost, most Chinese people should have such a general understanding: in a building, the cost of machinery and materials must be more expensive than the cost of labor. For example, if you build a house by yourself, when you are making a budget, you will definitely save more money for buying materials. If someone tells you that you may spend more on labor than on materials, you will definitely think that this person is crazy.

That's right, there's nothing wrong with that. In the direct cost, the labor cost has always accounted for a small head, and the material cost and machinery cost are the majority, which is the reality and status quo of the domestic construction industry, and this status quo has not changed even when Li Huayong was reborn.

Non-professionals don't need to know so much, as long as they know the concept of "three-seven opening". That is to say, to build a house, the cost of people accounts for about 30%, while the rest are material costs and machinery costs. Due to the different buildings, this scale cannot be very precise, but it is basically the case.

However, it should be noted that this ratio is only valid at home, and if it is placed abroad, especially in those developed countries, then this ratio will be reversed!

In developed countries, the cost of machinery and materials accounts for only 30%, while the labor cost accounts for 7 percent!

Knowing this, you can understand why Ito Construction refused to make design changes, right?

If the mechanical hole pile is changed to a manual hole digging pile, this not only has more safety risks, but also in the eyes of the Japanese, it needs to adjust the project cost.
