1. Why is BIM more than drawing NB?
What is a BIM model?
The strict concept will not be said, and it will be found everywhere. The BIM model can be regarded as a “database†that integrates various stages and various professional information. The database contains geometric information (three-dimensional) and non-geometric information (material information, component information, construction plan information, quality inspection information, operation and maintenance). Recording information, etc.), non-geometric information is "tied" on geometric information. With this database, you can add, delete, check, and change information, and this addition, deletion, and modification is to the extent that a BIM information element (such as a component or a piece of material information) is refined.
2. Why is BIM more than drawing NB?
Think of BIM as a "database," and traditional drawings can be thought of as "documents." For the database, you can develop programs to add, delete, and modify, but for documents, you can only watch. For example, based on the BIM model to automatically check for collisions, it is actually to find the "geometric data" from the database, and then calculate the resulting collision results. And based on traditional drawings, you can only find collisions with the naked eye, because the information on the drawings is not known at all. With this database, you can develop programs to do a lot of imaginative things.
3. What is the NB of BIM?
General non-BIM software, also use database management data, can also add, delete and modify, and where is the advantage of BIM? BIM is not only a database, it is also a centralized database, all the information is placed in this database, can be added and deleted by other professionals, other stages of personnel (provided that there are permissions), this is often said information exchange (information) Interoperability). This means that if you finish the design, the design results can be directly imported into the cost calculation software to automatically obtain the project cost, no need to repeat the modeling. The benefits are on the one hand, the improvement in efficiency, and on the other hand, the consistency of information. The former aspect is well understood, and the latter aspect means that if your design results change, the project cost can be automatically changed, and the calculated cost corresponds to the design result.
4. What is the benefit of BIM?
The owner is the biggest beneficiary of BIM. The benefits of BIM are comprehensive, including cost, quality, duration, and more. Let's start with the simplest engineering changes. Professor Skibnewski of the University of Maryland (editor of Automation in Construction, the most NB journal in the BIM world) counted more than 20 projects in the United States implementing BIM. The cost of engineering changes fell from 10% of the total cost of the project to around 3%. The ratio of domestic engineering project change cost to total project cost is generally 10-13%. Shanghai Center uses BIM technology to reduce it to 4-5%. You can calculate how much money you save.
Of course, BIM technology will bring many other benefits, such as project quality, construction period, and later operation and maintenance. These are difficult to quantify, so let's not say it.
5. Why is it not good to use BIM?
People: I don't understand BIM if I understand BIM. I don't know BIM if I understand professional. Frankly speaking, the quality of employees in the BIM industry is still low.
6. Does BIM have a future?
Greatly promising. See what Wanda is doing.
Wang Jianlin’s annual meeting emphasized the promotion of BIM technology alone.
Invest 200 million a year (heard)
Develop BIM platform
Establish BIM standards
All members of the group conduct regular BIM training and assessment (it is said that the test is still very strict)
Millions of annual salary in the industry to dig people (a brother went, did not ask if there is no million)
The Group has a BIM Director in each system (cost, engineering, procurement, etc.).
But it needs to be pointed out that BIM itself is just a tool, not a panacea. Wanda pushes BIM so arrogantly that the premise is that with Wanda's turnkey mode and light asset model, BIM is only a tool to serve these two modes.
7. What are the futures for BIM practitioners?
Not necessarily
High-end personnel have a future: such as BIM director, BIM system developer, project management staff who understand BIM, and designers who understand BIM.
Low-end personnel have no future: no engineering background, only people using BIM software.
8. What is the development prospect of BIM?
Internet and big data. There are too many things to pull here, and you need to understand it yourself.
