Who enmesh the pace of development of BIM application

Recently, the Ministry of housing and urban rural development of the study on the development of building information model guidance issued to guide and promote the application of building information model. Although the BIM high heels look very beautiful, but it is not easy to wear it.
2015, the construction industry information added positive. Recently, the Ministry of housing and urban rural development of the study on the development of building information model guidance issued to guide and promote the application of building information model. Although the BIM high heels look very beautiful, but it is not easy to wear it. At present, both the design enterprises and construction enterprises, BIM application rate is not high. Who is her stumbling block in an industry seminar, the experts have carried out in-depth discussion.
Reset business model
“ now in the design side, Party A is to design a map of the money, money, did not give BIM fee equal to the design unit free construction of this part of work BIM. So why do you say that the policy is more operational in Shanghai, because he has a supporting method. ” Yang Zhenqing, President of the Institute of building technology, Beijing six construction group.
In this regard, China Enfei Engineering Technology Co Ltd 3D collaborative design director Qin Feiyu also empathy: “ this is a business model, I have two projects in foreign countries, is an iron ore project in Anshan investment, is a typical BIM project. From the contract that foreign projects and our domestic projects are very different, our contract is the total price contract, foreign contract is open contract, is the unit price contract, will increase the cost of working hours increase. The results of these two contracts are different, the domestic design institute has no incentive to optimize the design. While foreign countries have such enthusiasm, in such a mechanism, they will continue to optimize the design, so as to play the advantages of BIM, you can see, fine. Once such a demand, with BIM is inevitable, because it can not do this. So I think this is a business model problem. And foreign owners will ask a professional consulting team, the size of the consulting team is not smaller than the design team. And the professional level of the design team, is a one - to - one docking, the project started when the file is also more comprehensive. What software to use, what interface, two-dimensional map with what details will be given. ”
In this regard, Beijing in the construction of integrated information center director Liang ship in an interview with the author concluded: “ from the construction enterprises, the real problem is who pays to do BIM from the revenue side, the owner is using the BIM maximum benefits, if the entity is built up and down, it will cause great loss. If the owner of the money, to make the works of great benefit to him. For example, Wanda real estate why sell so well, the design plays a great role in. ”
“ another problem is that the owner please do BIM design, intellectual property rights to the who? Intellectual property belongs to design institute, owner can obtain the right to use in this region by paying for the owner, as long as you don't take this outside design to do this project, can use this design to other construction enterprise. This solves the problem of intellectual property rights. ” beam ship out a prescription.
Open up BIM Ren Du two pulse
“ now without a software can do it from scratch, are all different software combination, now involves the software data exchange, data can be achieved between the upper and lower interaction, it has become a constraint for the development of BIM. ” Beijing construction research information center director Liang ship said.
In this regard, the author also Qin Feiyu spit bitter channel: “ software integration is an inevitable trend, but the problem now is not a vendor can provide a complete solution, is from design to production operation, something designed to production processes, the information is not the same, the first is the extension of data some software, good scalability, and some simply can not expand. To calculate the amount of time may encounter the standard problem, I calculate the amount of the computer in the national standard does not recognize the downstream construction unit does not accept. To the operation and maintenance phase, I may need to add some data; in the end, in order to speed up the operation, the model also has a lightweight problem, a lot of this work in the upstream and downstream. The model we built upstream is good, but we can't move downstream. I think there is still a long way to go to integrate the system, some of the work may require our users to do the two development. ”
How to change the current BIM information embolism embarrassment? New Teyao studio director Zhang Guohui BIM built in two innings of a company in cure ills: “ it depends on the network system, hardware system. For example, the software used by the design side, the construction side can not be used, because a file more than a dozen G, now the data cable hardware support can not open a model to wait two hours. If the network speeds up hundreds of times in the future, it is no longer a problem. ”
“ at present, some domestic software companies to accept all the company's domestic software data, only compatible, but he did not spit after eating, the data to his stop there, who do not give. I call on the domestic software vendors open chest, open data, the formation of a win-win situationTo jointly promote the development of BIM industry. ” Zhang Guohui calls.
“ middle-level managers also from the construction unit resistance, they have used a set of processing technology, the use of BIM will inevitably bring about process reengineering, they feel it is not easy, even if you give him money, he does not want to do. ” Yang Zhenqing to the author Tucao road.
“ from our point of view, the model has been built, but the project on the use of ordinary managers of these models, they do not want to use. Although the grassroots managers are critical, but the core is not in them, the key to see the project leader who has no intention to change the old model. ” Zhang Guohui, director of the BIM Office of the two companies in China, pointed out the problem. “ in fact, the project manager is more concerned about the input and output, no output no power. Spend money, see results, they are not enthusiastic. Therefore, the implementation of BIM to work hard from the results. To save money for the project, the project manager naturally needs. ”
Zhang Guohui further analysis: “ BIM the biggest advantage is the simulation, the potential risk of early detection. But in the end in the end how much money for the project, how much money can not be quantified. So now we push BIM biggest difficulty is how to do quantitative analysis with the owners and construction side. We can only be from the income and expenditure to help him, help him to check, really help him make money, turn around and then push the BIM system, and now we are going to be such a return route, directly pushedCan't get through. ”
