Is BIM a process or a model?

BIM is process or model

BIM is the use of these digital economic model can be cultural construction project research and design, construction, operation cost management process,Bentley ProjectWise and not just for that we want to produce the digital network model of the enterprise product, although the BIM model at the same time is also one of the results of the BIM process form, then BIM is the process is mainly or through the model? Let's first look at the so-called process is a need for what kind of process, BIM is the use of building digital technology model inside the information in the design, construction,Bentley BIM operation and maintenance of various different phases of the building between the data analysis, simulation, visualization, construction drawings, the process of quantitative statistics.BIM Viewer Obviously the core here is information, a student to create, collect, manage, apply the process of relevant information, and then look at the so-called model, which is China as a kind of virtual model of the object building of our national work, so if we want to this problem model what use that? Of course is to support to help our design, construction, operation and maintenance decisions and implementation. By what support? Is to use the information that exists in the risk model as a teacher support, so in order to the so-called BIM model, its core competence is not the model itself, but stored in the expertise of the information in which the BIM that is the process control is also the impact of the model, but ultimately is the information is the carrier of the information stored user is the creation of the time management and the use of accounting information process.

BIM how to organize information

At the heart of BIM is information. In different project phases, different participants will organize, manage and use the same information in different ways. The result is information redundancy. Even if multiple project documents contain a single piece of information, it may just be expressed in different ways. As project informationization continues to evolve, information redundancy leads to potential coordination errors, creating a need for information checking processes. Information checking at different points in time consumes the project's budget and schedule, and errors not caught by coordination checking are brought to the construction site, causing construction delays and duplication of effort, resulting in additional project costs. However, we need a unique engineering information model that represents this construction project, which can be derived from the application of specialized work information, structural analysis, daylighting simulation, quantities statistics, optimization of construction solutions, etc. by different participants at different stages of the project.

The basic elements of a unique construction project are combined to form an equally unique construction project, where different professionals are required to use different technologies and methods for different purposes during different phases of construction and use, and to produce different types of documents representing these processes and results as contractual submittals, which is a description of the relationships between the information and different applications represented by the process ontology.

Is BIM one model or multiple models?

This is our contact BIM, the application of BIM colleagues often encountered the problem, there are usually two kinds of statements, one, in the introduction of the concept of BIM usually see the Chinese such as: BIM includes all the company's geometric, physical, and performance for the digital expression of the information, and all the data and information related to the building are stored in a single model, the different project management participants in the different project Development stage students need to use a lot of nothing product information system can be obtained from the BIM model, BIM and China's current widespread research and use of CAD and visualization processing technology has different, the latter two only contains part of the building's accounting information. Secondly, there are also some BIM information mainly introduced in the project design of different educational stages, different members of the project community will establish their own BIM model, common BIM modeling methods include site model, architectural engineering model, structural theory model, electromechanical model, construction process model, coordination capacity model, as-built model, and so on.

A single model describes on a logical level, BIM is a model that contains all the information of a building, and multiple models describe on a practical level, due to technical, business, legal and other constraints, project members have to build their own BIM models. Secondly, from the point of view of information organization, creation, management and application, one model or multiple models are not the key to solving the problem, just like what software you use for Bim, it's just a choice of tools and methods, the key is how much information is used in the construction project, in what form, how many project members, in what kind of work, accurately, efficiently and completely, how much improved productivity, how many potential errors are avoided, how much construction time is reduced, and how much project cost is lowered.

What is the mission of Engineering and Construction Wealth BIM?

All developed and more developed countries invest a significant portion of their GDP in fixed planning, design, construction, operation, maintenance, renewal, demolition, and so on. In the process, a large proportion of construction projects have been delayed, the problem of cost overruns, the increasing pressure to improve efficiency in the global construction industry, in the United States, the study of the relevant departments shows that there is a 31% difference between 57% and 26% in the construction and manufacturing industries.

Will BIM change the responsibilities of project participants?

We teachers can go through and see a whole lot of information discussing process changes, changes in the development of teaching methods for project management implementation, changes in BIM competencies as well as requirements, and changes in the organizational structure of BIM teamwork, but one thing is almost fully certain, the responsibilities of the various project members in the project will not change because for each project member's theoretical expertise, experience, and responsibilities in the economy of construction and operation of the Provide a national excellence in engineering and construction projects necessary Although the project members duties do not change because of the BIM changes, but the relationship between the members of the country and the way of life of the work of the members of the time to change, and even can be a big change. The original project members are more concerned about each other's duties, each has to improve their own work and learning goals, sometimes members do not become competitors because of their own interests and risk conflicts, with BIM more emphasis on collaborative work, the success of the project as a family member of the common goal of the project, the original project staff is more sequential, with BIM may bring more work is carried out in parallel Carry out. The purpose of applying BIM is not that they want to make the construction and operation service work of engineering and technology projects more complicated, but that they want to be able to find better ways to realize the market objectives of different industries to complete the system engineering investment projects efficiently and with high quality and to meet the needs of our customers in the construction industry.
