In last few years, support energetically in what the country reachs a government below, BIM technology received extensive promotion and application. BIM also became more open to question topic inside course of study, have those who hold crosscurrent, also have special approbate BIM technology, what controversy does BIM have? To BIM, are you how look?
Controversy one: What is BIM?
Be aimed at the definition of BIM, have various views, look in BIM elder brother: The BIM model that BIM technology produces is a database, it is a project multidimensional the database that spends structuralization. What cries multidimensional spend structuralization? The data that after a lot of dimension spent parameter to decide, needs namely can be summarized, the analysis comes out one of characteristics with the most important structuralization. Had this database so, the ability of construction company enumerated data is great different.
Engineering industry is the industry of experience dominant sex all the time, what price should declare to tap a head when the enterprise bids, should organize data of how many production, much large contingent to also want to come by experience clappers, these bring about resource wasteful, time limit for a project is protracted. And the occurrence of BIM technology, can help enterprise compose build piece multidimensional the project number model that spends structuralization, the data that decides nice thought spends parameter place to need can be analysed get, data granuality also can propose step to compose subtly, conduce to analytic cost directing production, organize resource plan.
Production, construction, design carries all project data in dimension and business data can go on to load even. This to load depends on concerning couplet sex, the data with all and related equipment that should find this compose to build only is OK be come to by v. Have summary of a word so, had BIM, the gift that makes a project had a when project management needs all the time the mainest platform that prop up, the respect is gotten to be able to help us get accurate and seasonable, complete project database at any time and place in data.
Controversy 2: BIM whether does implementation apply in coordination?
Below traditional pattern, bldg. resembles manufacturing industry very hard same, come out to build true prototype a computer, and be designed a lot of times, ceaseless and perfect, this is to build a project cannot susceptive. But had BIM technology, can use BIM technology and three-dimensional technology, before engineering construction, imitate of process of will whole in computer construction, all problems that appear design phase are solved first, whole essence of life calculates all data after be being used at exact plan, resumptive break earth, can improve efficiency greatly so. So, BIM technology helped an industry solve a big spatio-temporal difficult problem.
Controversy 3: Is BIM technology mature now?
Current, country and government already published a lot of policy about BIM, that whether is technology of BIM of that is to say very mature? Actually everybody still has a lot of doubt, because a lot of young associate are spitting groove, I had used BIM technology, bad to use, have investment only, did not yield. Sum up the current situation that shows level so now with 3 words is more reasonable:
(1) BIM is in development phase nowadays, if use the solution of all sorts of software firms, there already was application in construction phase, this is without a problem, but space of the latent capacity that expands at BIM technology relatively, development will tell, BIM technology still is in development phase, had not gotten large-scale use;
(2) value is already special and enormous, mix according to project characteristic executive phase, had used existing application, choose proper program and method, can win very tall value get one's own back completely;
(3) BIM technology is the technology with revolutionary bldg. . This means an enterprise to had used BIM technology, can not make a trade certainly the first, but if need not, can be washed out by the market.
Controversy 4: Is technology of BIM of 3 edges project useful?
Chinese project is bigger, it is 3 edges project mostly, often also hear a lot of managers to complain: The building on pilot project has been built, the model in the computer of BIM group has not been built good, efficiency is so low, want BIM technology what to is used? So whether does BIM technology fit Chinese project? If plan choice is right, larger and complex, jump over the 3 edges, project that jumps over time limit for a project to tighten cost to press muscularity more applicable, and the value of BIM is reflected more apparent. Even if be a little janitor's room, in cost plan management field also has great value to be able to be dug. The key is BIM builds a model, the adjustment of the model, operation, applied rate ability that cooperate with is ambitious, if have such platform that build a model, can get used to 3 edges project completely.
Controversy 5: How does profit of the company after is data transparent do?
Building an industry is transparent least of all almost, in the meantime, profit also is lowest almost. Accordingly, opaque bldg. did not bring Zuo profit to the enterprise. So construction company should change the concept that he manages now, should change ostrich thinking active hug is transparent, this also is the trend of the industry. In the industry transparent circumstance falls, spell cost, spell quality, spell plan, especially how does cost respect compare others lower, company ability remain invincible.
Controversy 6: Have super BIM software?
Get BIM technology now, a lot of enterprises are being done actually pilot, the effect is not quite ideal. Because firm of software of a few BIM hopes the user of all China, to carry dimension to construction from the design one bamboo pole inserts the software that uses him after all, this brings a disastrous issue to construction company. Because the project is honest too complex, information content is tremendous, problem of the technology of the project, cost management, quality, safe problem is waited a moment, too much too miscellaneous, dimension of impossible that with a software sweep the deck is designed, construction, carry 3 large stage. Recognize after this, from the point of present BIM technology characteristic, it is to should seek each level certainly the most professional, most can of be born specialization the strongest software takes ability to use, can get very good devoted get one's own back certainly.
Controversy 7: How does information safety do?
BIM technology had arrived now the phase of application of wide area newwork, more and more BIM models are put to high in the clouds, put to the server to share, go making various application in coordination. So, to the server of where should be BIM model put? Actually, now any the program that BIM technology firm can offer company course, no matter be the solution of high in the clouds or company level illicit,have the plan of the cloud. And the business should have protected him data, want to use the safest technology of course, cannot use a model simply to do so, will big project is passed automatically abroad on the server of the company, this has a problem quite. Want research and development to have the BIM software of own property right and applied technology so, in order to ensure the information safety of building model.
Controversy 8: Is investment return rate high?
BIM technology of more than 10 years uses practice, the conclusion that reach is already special and clear: The BIM technology program with right choice and executive method, can realize 10% above plan to chase, the do poorly done work over again of 10% above decreases. And the data capacity of BIM can decrease to calculate leakage less, raise income of Zuo settle accounts, can promote the management of spot quality safety capability substantially, promotion cooperates with ability.
Use BIM technology to be able to reduce the experience demand of pair of spot administrator, can form the database of a lot of normative experience of a tiring-room prop up, the project administrator that is front offers powerful data to prop up, the technology is propped up. Form model of complete of a project finally, this model can use the complete lifecycle of the project, can use economic resource each years.
Although BIM special all the time open to question, but a viewpoint has done not have controversy, it is the trend that BIM technology can make our industry develop.
