What is the thing called bim?

Today, most people on earth who do this seem to know what BIM is. Isn't it building information modeling or building information modeling? You are right.

BIM definitions are available on the Internet, including Bim, building information modeling, and building information models. Wikipedia and Baidu have all kinds of statements, but they all share a common feature, one word, Xuan. Three words, rather mysterious. The more you don't know what it can do for you, the only thing you can easily understand is to use new software, such as Autodesk revit, Bentley architecture, graphisoft archicad, and digital projects.

Then someone will use it, and then everyone will not use it. The principle is very simple. It seems that it is not as fast as AutoCAD failover.

However, bim has not withdrawn from the stage of history, but has become more and more lively. It is so busy in the United States, where it is home that even the national Bim standards in the United States have been developed. In addition, like all the good and bad things of Uncle Sam, they have to rush out of the United States and go to the world.

Hong Kong has always been the trend vane in Asia, and Bim is no exception. Over the past few years, there have been more than 100 projects using Bim. It seems like a word can be used to describe it: it's a big deal.

Hong Kong is a region with one country, two systems, and its biggest feature is that its owners must be unprofitable. In this case, bim must have brought benefits to Hong Kong's owners.

BIM may be really a good thing!

In this case, it seems that people in China have not fully understood this, but they have tried it. Bim is not simply a software change.

So what is bim? To answer this question, let's get up first and see how the house was made.

1. How did the house be built?

When humans ask, God will laugh. Of course, humans are in the next place. All the people on Earth in this line are God.

L owner/investor-pay

L designer-Drawing

L developer-sell the house as shown in the picture

L materials surveyor-calculate money according to the picture

L developer-bidding based on pictures

L construction enterprises-build bricks Based on pictures

L Property Management-photo View Management

It's too easy! Even the people on earth who are not doing this know! So humans laughed.

In addition, the Earth people who have been in close contact with the house and do not do this also know other things:

L Wire Breaking and pipe hitting are always required during Decoration

L luxury hotels and office buildings are marked with signs of "do not meet me" and "Pay attention to your feet"

L some rooms are frozen and some are hot

L I always see some newly created places, and then come back.

L The pipe burst will always take more than half a day before closing the valve.

L The description of "beard project, bean curd project, and phishing project" is vivid and vivid.

L it sounds very professional, and it is very expensive to change it.

L "design change" is changed once for money

L The place where the hole should be left is not left, or it is not large enough. What should I do? Hire someone.

L you cannot renew the service. Note that this is not a force majeure event, such as a result of the earthquake and tsunami. It is a normal charge.

L ......
I think everyone can understand that, either the person who looks at the picture is wrong, or the drawing itself is wrong. Congratulations! Correct!

2. The drawing you got is wrong.

To say this, the designer will certainly not play with me, because I am talking about facts.

It is also true for most designers that they are neither professional nor conscientious nor professional.

Did the designer mean it? You did not mean it.

There are many reasons for drawing errors:

First of all, they are independent of each other.

The design should be at least professional in architecture, structure, waterway, HVAC, electrical, budget estimates, Data, communication, security, energy conservation, etc. The division of labor between these majors is clear and cooperation is vague, every professional drawing is correct and there must be problems when combined. There is no dedicated position responsible for multi-professional coordination, and some are only professional coordination meetings. During the meeting, everyone is still staring at their own drawings. They are very professional, conscientious, and dedicated. The result is that there is a problem with the drawings of each set of projects. It is either a fight between different professional content or a collision of your head when you come in.

Remember that there are not almost every set.

The second is the paper discussion.

This is a better understanding. In Design and Construction schools, two majors are learned. One is mental labor and the other is physical labor. designers think that the theoretical level of construction personnel is insufficient, the construction personnel think that the designer is a conversation on paper. I have not found any strong evidence for the first statement, and the second statement is unfortunate. It is a fact. The specific manifestation is that some of the designer's drawings cannot be made during construction, or even if they can be made, they have to take the effort.

At this time, we need to ask the designer to change the drawings. The construction engineer should tell the designer how to change the drawings. After the change, the construction engineer should follow the new drawings for construction.

You guessed it. Every project's drawings encountered this problem.

Third, frequent changes.

We all know that the claim for the birth of an ugly girl is made by a great man-created beauty. The so-called changes are made on the original drawings. After finishing the changes, you must remember that the changes were corrected and where they were originally made. Otherwise, the consequences would be very serious and the owners could only get angry.

Everyone on the Earth knows how the hacker map is developed.

The property management company operates and maintains the property according to the worker diagram.

You will answer all the remaining questions. For example, how is a pipe worn?

The drawings and physical objects are not correct. Everyone on Earth knows that ......

3. We were fooled by the computer effect.

I have a lot of professional titles in the computer industry, such as visualization, computer graphics, and virtual reality. Do you understand what it is?

That's right, acting. Play the house.

In most of the history of mankind, the vast majority of people are illiterate, and the drama is easy to understand. Therefore, it can be used to educate people and inherit civilization.

During house building, a set of project drawings includes dozens or even dozens of thousands of professional drawings, and tens of thousands or even tens of thousands of project participants. Isn't it hard to figure blind, computers, animations, or virtual reality can communicate information and assist in understanding.

The difference is that there may be a gap between the characters and prototype in the drama and it may play a better role in education. However, if the computer effect of the house is different from the actual house, it will not be a problem, but there are serious problems.

What are the facts?

The house is made according to the drawings, and the drawings are constantly changing.

Q: Are you constantly changing?

A: No.

The conclusion already exists.

Yes, the problem is really serious!

4. The owner is a big leader

Premise 1: The owner pays the designer for design, and the designer delivers the drawings to the owner;

Prerequisite 2: during the construction process, it was found that there was a fight between mechanical and electrical engineering. The next step is: the construction is suspended. When the designer modifies the drawings, the material surveyors recharge the price, the owner adds the investment, and the construction starts again;

What did the designer lose? Drawings and ink.

What did the contractor lose? Not found. You may make more money.

What did the owner lose? Money and duration.

Reasoning: the owner is a big leader.

Premise 1: The owner spent a lot of effort on bidding and bidding, and determined the project contractor according to the principle of high quality and low price;

Prerequisite 2: at the beginning of construction, I found that I forgot to draw some drawings. Next: The owner asks the designer to supplement the drawings, re-calculate the price, make additional investment, and continue the construction.

At this time, you can no longer tender? You are correct!

What did the designer lose? Drawings and ink.

What did the contractor lose? What do you mean?

What did the owner lose? Money, construction period, quality ......

Reasoning: the owner is a big leader.

......

5. What is the BIM thing?

As the owner,

Is the house you want to build recognized by the market for constant appreciation?

Do you want to greatly reduce the additional budget?

Do you want to ensure that the project is built on time?

Do you want to find out and modify the design drawing errors before the bidding?

Do you want to simulate the construction scheme provided by the contractor according to the actual situation (not in the joke?

Do you want to detect unfeasible or unreasonable Construction Schemes in advance and adjust and modify them before construction starts?

Do you want to get the cost impact of any change quickly or even in real time?

Do you want to dynamically record all changes and get a building information model consistent with the actual building for O & M in the next decades?

Do you want to dynamically integrate, manage, and track the procurement, transportation, installation, and daily construction plans?

Do you want to visually introduce and analyze the projects of investors and customers at any time at different stages?

What do you want to see, animation, and virtual reality, is not just a false reflection but a real reflection of the real situation?

......

If it is written here, the earth may know what I want to say.

Yes. For the owner, BIM is the one that can help you achieve the above goals.

So,

Is Bim software?

You already know the answer. The software is just a Bim tool, such as a screwdriver. Of course, only screwdrivers cannot make cars.

Is Bim the information model of a building?

Of course not. The information model is only the result of Bim. And most people are still wrong about this result.

It is estimated that people on earth will scold me for doing so much. What do you mean by BIM?

My answer is: BIM is a Bim consultant.

The proof is as follows:

Because,

BIM = Let the owners see the project's future crystal ball = save money + save time + high quality.

To achieve the above objectives, it is difficult to achieve without Bim tools (software), and without Bim professionals, it is certainly impossible.

So,

BIM = Bim professionals + Bim tools.

Because,

BIM professionals will certainly use Bim professional tools.

Therefore,

BIM = Bim professionals.

Suppose,

We call Bim professionals Bim consultants.

Then,

BIM = Bim consultant.

The proof is complete.

6. Could you ask the designer to be a Bim consultant?

Since BIM is a Bim consultant, who can be a Bim consultant?

The answer is simple: Bim consultant = professional + Bim.

People who do not know Bim can't do Bim consultants, but those who do not know professional can make Bim visualization and make it a joke.

BIM can do CAD, but BIM is not CAD.

BIM can do visualization, but BIM is not visualization.

It is estimated that you have understood one point: designers can learn bim To become Bim consultants!

Very correct! If it is purely technical. However, designers cannot be Bim consultants.

The principle is simple:

One of the most important tasks of a Bim consultant is to identify the design drawing errors. Therefore, if a designer is a Bim consultant, you will know the consequences.

It is like the consequences of accounting and auditing.

BIM consulting should be another independent consulting service provider that the owner is hiring, planning, design, construction, material measurement, energy saving, building intelligence, sales, property management and other services.

The task of Bim consulting is to help the owners pick up the waste of money from the construction waste, so as to ensure the construction period, quality, performance, and ensure that the House is the house the customer wants.
