Chapter 249: true cable volume
Song Xiaoshan then arranged: "I have some practical and comprehensive construction organization design documents on my computer, and I will send them to you later.
The first step is to browse the bidding documents, the bidding list, familiarize yourself with the bidding construction drawings, and then hold a short meeting to select a standard construction organization design template document. I will inform you about the time of the short meeting and inform you of the location. Still in this room.
The second step is to compile a targeted construction organization design document according to the profession.
The third step is for me to communicate and negotiate the documents prepared by everyone with everyone, and quickly combine them to form the construction organization design documents for each first tender section.
The fourth step is to cross-check and review the construction organization design documents of the first tender section.
The fifth step of the work is to use the construction organization design documents of the first tender section to change the second tender section and the third tender section. During this process, I am responsible for changing the second tender section, and Zhao Dajin is responsible for changing the third tender section. , Wang Bin, and Zhou Qingchun took turns to cooperate with Zhao Dajin and me in the revision and improvement work.
Did you all understand? "
The three replied together: "I understand."
Song Xiaoshan ended the meeting and said, "Then break the meeting and act."
After Song Xiaoshan announced the adjournment of the meeting, he hurriedly sent the three construction organization design documents mentioned at the meeting, which were usually collected and sorted out, to the three QQ mailboxes.
After Song Xiaoshan finished these things, he took out his mobile phone to call Lin Yiping and said, "Lin Gong, I have already received the email you sent me.
Since there are many tasks and the time is quite tight, I mobilized Zhao Dajin, Wang Bin, and Zhou Qingchun, the backbone of the Bowan Project Department, to participate in the preparation of the construction organization design.
We held a short meeting just now to discuss, in fact, the time is very tight, because you will open the bid on the sixth day, so our project considers that the construction organization design should be able to have printing, binding and sealing by the morning of the fifth day at the latest. Otherwise, it may affect your participation in the bid opening of the project.
You can see whether this schedule is consistent with your schedule, and whether there is any conflict. If there is a conflict, we will discuss and adjust it. "
Lin Yiping replied: "There are quite a lot of things during this time, and I haven't had time to arrange the time for closing the bid and opening the bid.
However, you think that your consideration and arrangement are more thoughtful, so let's make arrangements at this time point first.
Thank you Manager Song for such a strong work support. "
Song Xiaoshan replied: "It's all the company's job, and it's also an honor for the project department to accept assignments. We'll keep in touch if you have any questions."
After Lin Yiping ended the phone call with Song Xiaoshan, she came to Zhang Yunqing's temporary work station: "Gong Zhang, have you received all the documents sent to you?"
Zhang Yunqing replied: "I have already received it. I am already using the software to set the fixed price."
Lin Yiping replied: "Okay. How many days do you estimate that you can finish the part you have done?"
Zhang Yunqing replied, "It's estimated to take three days."
Lin Yiping replied: "Okay, once you're done, send it to me for inspection, and if I'm done, I'll send it to you to help with the inspection."
Zhang Yunqing replied, "No problem."
After Lin Yiping left, Cai Bai'an came to Zhang Yunqing and asked, "Gong Zhang, look at what this icon is?"
Zhang Yunqing replied, "It's the valve."
Cai Bai'an asked again: "What is the difference between the DN of this pipeline and De?"
Zhang Yunqing replied: "1. DN refers to the nominal diameter of the pipeline. Note: this is neither the outer diameter nor the inner diameter; it should be related to the British system in the early stage of the development of the pipeline d project;
It is usually used to describe galvanized steel pipes, and its correspondence with imperial units is as follows:
4 in charge: 48 inches: DN15;
6 in charge: 68 inches: DN20;
1 inch tube: 1 inch: DN25;
Inch two tube: 1 and 14 inches: DN32;
Inch and half pipe: 1 and 12 inches: DN40;
Two-inch pipe: 2 inches: DN50;
Inch tube: 3 inches: DN80 (also marked as DN75 in many places);
Four-inch pipe: 4 inches: DN100;
2. De mainly refers to the outer diameter of the pipe, which is generally marked with De, and needs to be marked in the form of outer diameter X wall thickness; it is mainly used to describe: seamless steel pipes, plastic pipes such as PVC, and other pipes that require a clear wall thickness .
Taking galvanized welded steel pipe as an example, the two marking methods of DN and De are as follows: DN20De25X2.5mmDN25De32X3mmDN32De40X4mmDN40De50X4mm and so on. "
Cai Bai'an touched his ears embarrassedly and said, "Gong Zhang, this is too complicated. Do we need to remember so many things when doing budget work?"
Zhang Yunqing replied: "We only need to know a little about this situation when we do the budget work, so don't make a joke, but in the process of calculating the amount of work, don't write the wrong content on the construction drawing. Write it as DN, if others are De, you can write it as De. Otherwise, our material procurement will not be able to find the price when inquiring. The price inquired is wrong, which will cause huge economic losses in serious cases Cai Bai'an replied: "Okay, I remember it. How to calculate the length of this water supply pipe? "
Zhang Yunqing replied: "According to the length of the size shown in the figure, the unit is m, and the engineering quantities are divided according to the size of the pipe diameter. All the engineering quantities of the same pipe diameter can be added together."
Cai Bai'an asked, "How to calculate the length of the cable?"
Zhang Yunqing replied: "The length of the cable should first be calculated according to the length shown in the figure, which is similar to the calculation of the length of the water supply pipe. Secondly, the position of each lamp should be calculated as an extended meter according to the regulations. The third is to consider a slack factor according to the quota regulations. The fourth is to calculate all the lengths from the distribution box to the end of the circuit.”
Cai Bai'an said: "Zhang Gong, the fourth item is a bit puzzling."
Zhang Yunqing asked, "Why is it so confusing, please explain it carefully."
Cai Bai'an asked: "From the distribution box, there are many loops that are actually repeated. It takes a long distance to separate the lines. Then, should the repeated lines be counted as the engineering volume of his cables? If so, no Did you double-count the amount of work?"
Zhang Yunqing replied: "The key point of this problem is that, when each electrical circuit comes out of the distribution box, the cable to the end of the circuit is continuously broken, cannot be disconnected, and cannot be connected.
Therefore, the engineering quantity of the cable is the overall length from the distribution box to the end point, and the engineering quantity that needs to be added separately as explained just now is the real cable engineering quantity. "
Cai Bai'an asked again: "Then how to calculate the amount of excavation and filling for the pipe communication of this cable?"
Zhang Yunqing replied: "The calculation of the amount of excavation and filling of the cable's pipe communication, first of all, the length of the pipe communication, no matter how many cables are in the same slot, only one length can be counted, and the length of each cable in different slots must be calculated. "
