Although there are still problems in the application of BIM technology at present, we also see the practical value of BIM technology from all aspects of application. The following is a summary of the bim graduation design I compiled for you, hoping to bring you help!

Summary of BIM Graduation Design 1 1. The concept of BIM

BIM (Building Information Model) literally refers to the building information model, which is different from the traditional three-dimensional model, and its value is reflected in the informationization of the model. What does informatization mean?

For a simple example, what you see in the traditional model is only a column with material, and you can't get any other information about the column; In the BIM model, as long as you click on this column, it is possible to show its decorative materials, architectural practices and structural characteristics. There are several columns like this on this floor, and you can add other information according to your needs. It can be seen that BIM is a model supported by a lot of information and data (including spatial and logical attributes).

Second, the application of BIM

The application of BIM has not yet formed a complete system. In the general direction, the ultimate goal of BIM technology application is the integration of design, construction and operation and maintenance, that is, some experts say that BIM application runs through the whole life cycle of a building. However, as far as the project application practice of some enterprises is concerned, BIM can only be applied to half a life cycle, or even to one stage. Now the application of BIM is just a process of exploration and progress. Each enterprise applies BIM technology from different entry points according to the nature of its own industry. The application of BIM in different stages shows certain advantages:

1. In the design stage

Some design institutes have also begun to use BIM software for design. Generally, design institutes will use some modeling software to build a three-dimensional model for Party A to see, but the application of this model is nothing more than that. Using BIM design can continue to use the model in the scheme stage, and all the majors used are based on a model design, which increases the information of their respective majors and enriches the model. In the process of design, we can also check the mistakes, omissions and collisions between different majors. You can analyze the collision of the model and display the collision place for easy viewing. Collision includes hard collision and soft collision. Hard collision refers to whether there is collision between solid components, such as whether the beam will fight with the position of equipment pipeline, whether the column will overlap with the position of the door, and so on. Soft collision refers to logical collision, such as whether the door is open or closed, but will there be any problems in the process of opening; Or whether the height of the space above the stairs meets the requirements. Fine modeling can also help construction. For example, in steel structure engineering, many components can be made directly in the factory according to the model, which avoids the problems of inconsistent dimensions and difficult welding operation in the construction site, improves the overall construction efficiency and realizes factory construction. Or the construction unit can use the designed model to add relevant construction information to assist construction and project management, and even continue to use the model in the subsequent hardcover and operation and maintenance stages.

2. In the construction stage

Some experts of the construction party believe that for the construction party, they tend to train their own construction personnel to build BIM models according to the designed drawings, and are unwilling or unable to use the models of design institutes. They did this for two reasons. First, the current BIM technology has not been popularized, and various design institutes will explore some of their own methods. They don't want to give their models to the construction unit for free, because it also involves some of their own technical cores. Secondly, the model of the design institute can't really assist the construction, because the construction is a dynamic process, a structural member may be completed through many different processes, and there are many structural measures, which are not considered by the designer and will not be reflected in the model. For example, the infilled wall may be a wall in the designer's model, but in the construction process, the same wall also includes Rachel bars, and the structure such as oblique masonry is not reflected when the wall is laid to the bottom of the beam; For example, pile foundation, the designer's design pile length refers to the pile length after construction, but in actual construction, the pile length is dozens of centimeters longer than the design pile, and then the excess concrete is chiseled off, leaving the steel bar anchored on the pile cap. This difference has a great influence on the cost budget.

What kind of value can BIM technology bring to construction enterprises?

2. 1 The first step for the construction party to contact a project is to bid. In the bidding stage, the appearance of the completed building and the functional layout of the building can be visually displayed to Party A through the BIM model to facilitate communication; At the same time, it also enhances the image of the enterprise and enhances its core competitiveness.

2.2 Before the project enters the site for construction, the site layout can be carried out through BIM fine modeling, and the entry sequence of all mechanical equipment and the moving route of vehicles can be dynamically simulated, so as to avoid possible collisions and restricted mechanical operation areas. In the construction stage, BIM can also be used to simulate different construction schemes to choose the best one. (Mainly through adjusting different construction procedures, perfecting related construction technology, carrying out as many working faces as possible at the same time, reasonably arranging the whole construction process as a whole, and combining the progress and cost budget of different schemes, comprehensively selecting the optimal construction scheme. In other words, BIM technology can provide us with a real and predictable result by simulating the construction process, and maximize the benefits by choosing the optimal scheme.

2.3 BIM technology can realize the information management of construction projects. The mobile client of the project is established by BIM model, and technicians can update the construction progress every day, input construction information (name of a construction team, bid section, completed workload, or reasons for work lag), and the list of expenses and workload can be directly generated as text output. Large buildings often change, and by the end of the project, the change management is chaotic and the information is incomplete. The changes in the BIM model can be

If the model is changed in real time, it will be saved as different versions, and the changed text will be saved synchronously to improve management efficiency. After the project is completed, all the project data can be found and output, saving a lot of time to sort out the data. The owner can use the client plate to check the progress of the project and all kinds of construction information synchronously, keep abreast of the recent situation of the project, and communicate with the owner conveniently and intuitively.

3. During the operation and maintenance phase.

At present, some projects have been completed, and Party A requests to rebuild the BIM model. BIM technology can truly reproduce the architectural scene through a three-dimensional model, roam to all corners, and view various information such as equipment, pipelines, entrances and exits at the same time, so as to improve efficiency through information management. For example, if a pipeline is damaged, you can view the manufacturer, model parameters, installation unit and installation time of the pipeline on the model. For example, if you want to know the fire control facilities in a place, you can find out where the nearest fire hydrant is, how many safety exits there are, which is the best one, and so on.

Third, the existing problems

Generally speaking, BIM technology is the development trend of the future construction industry, which is beyond doubt. However, after listening to the experts' speeches, I personally understand that there are still some problems in the application of BIM technology.

BIM software integration is not enough. First, the BIM software used by everyone is different, most of them are foreign software, and none of them can be recognized as satisfactory after secondary development to meet the needs of our unit. Second, there is no good platform that can provide various interfaces to meet the needs of various occupations. Some professional models have to be imported and exported through various software, which is very cumbersome and easy to cause information loss.

At present, the design, construction, operation and maintenance of buildings are separated, which may lead to three models of a building, including a lot of repetitive work, and the construction model may require the design institute to review the structural changes.

Four. conclusion

Although there are still problems in the application of BIM technology at present, we also see the practical value of BIM technology from all aspects of application. The application of BIM in the future may promote the development of the construction industry in the direction of design and construction general contracting. BIM will be used from a project, and through different stages of project operation, the same model will be continuously improved, and professional information and data will be continuously increased. This not only gives full play to the professional advantages of people in various industries, but also enhances the liquidity of data and saves time, manpower and material resources.

Verb (short for verb) Thank you.

Thank you for giving me this opportunity to study, and for your guidance and concern in my study and life. As a member of the design institute, adopting BIM technology in the design stage is a part of the whole life cycle of BIM technology in architecture. I will take this opportunity to continue to study BIM technology in depth and contribute more to the BIM technology of design institutes and companies.

Bim Graduation Design Summary 2 bim Application Since 20xx, Xichuang Studio has been making unremitting efforts and attempts in collaborative platform application and bim software promotion. After different stages and levels of preparation and accumulation, some sub-projects have been drawn by BIM software revit, and some have been realized by BIM software archiCAD to promote the whole team from scheme to construction drawing, and some progress and achievements have been made. Thanks to the platform and strong support provided by the director of animal husbandry,

Several aspects of experience and ideas are summarized and shared with you.

First of all, bim design is not simply a matter of drawing with another software. The method of bim software design and drawing from the traditional main application of CAD needs the innovation of drawing habits and design concepts, the support of computer network environment and the cultivation of teamwork consciousness. At first, my workshop established a network working platform that can store and enjoy data through NAS server, and then began to try the application of cad reference and drawing set, and designed with the reference of structural specialty. The application of drawing sets enables people to quickly adapt to the framework interface of bim software, and the awareness and habit of collaborative work in bim design is gradually established through the application of CAD reference and collaboration by many people. Practice has proved that it is really necessary to promote bim software through such a transitional stage in the early stage in view of the current general working mode and software application degree in our hospital.

Secondly, the understanding of bim design and the significance of applying bim software at this stage is one of the fundamental issues that determine the ways and means of learning and popularizing bim software. Personally, a prominent problem is that many people have an ideal understanding of bim software, and think that it is scientific and accurate, and can solve all aspects of drawings, budget, construction and so on at one time. It is true that bim design can reach such a level. However, judging from Party A's situation, design cycle, design cost and multi-disciplinary cooperation requirements of most projects we are facing at present, the conditions and time simply do not allow us to reach the above level with bim software, and it can even be said that it is unnecessary (except for EPC projects that Party A requires our institute to undertake). So, why start studying? My personal feeling is that if you skillfully use bim software, you can really improve efficiency and accuracy to a certain extent.

And invisibly cultivated a more scientific and closer to the real construction process of thinking to promote and complete the design. In this way, even if Party A does not require bim design at all, it is still worth trying and learning. Only by making bim software better and faster than traditional CAD can we cope with more projects in the future. Party A requires us to apply bim software to a deeper and more comprehensive degree, so that we can have the opportunity to explore and explore the broader space that bim software can provide us.

Thirdly, in terms of specific learning and application, I summarized our team's experience as follows:

First, don't learn and use the software divorced from the actual project. In addition to drawing some completed projects in order to be familiar with the software operation in the early stage, it is suggested to boldly try to apply them directly to the actual project promotion process in the later stage. Of course, many colleagues worry that being unfamiliar with the situation will delay the progress of the project. This risk definitely exists. Personally, I feel that there is no good way to solve this problem, and it is bound to take more time and encounter various problems for the first time. But only by solving problems one by one in practice can we master bim software and its design logic different from traditional methods, which is a link that no one or any team can skip. But if you don't practice on the actual project all the time, it is estimated that you will never master bim design.

Secondly, it is suggested to practice in a bim design project team, that is, take a suitable project and all participants in this project use bim software for research and promotion, which can greatly reduce the information loss in the project promotion process, promote the members of the team to learn from each other and help each other, and try bim collaborative design within the project team. In addition, if bim software is used for construction drawing design, it is best for team members to have a certain foundation of construction drawing design, otherwise they will feel that they have no way to start and do more rework, and it is difficult to feel and explore the advantages of bim software for construction drawing design.

Finally, bim design can never replace the designer's technical control and the accumulation of project experience. These qualities are decisive and key factors no matter what software you use to draw pictures or bim, and computers can never replace the human brain. On the other hand, if the bim system design platform is to be built, the requirements for human resources and project management are higher, such as time node control, scientific human resources allocation system, project management promotion, quality evaluation standards, etc., which are irreplaceable human factors to ensure the smooth bim design. Accumulation in this area may be a longer way.

At present, we are still in the initial stage of application. Bim, a profound design pattern, still has considerable space for exploration and research, and we will continue to deepen it. Thanks again for the strong support of workshop leaders and the joint efforts of team members. I sincerely hope that we have spent so much time and energy to save us more time in the future and create more value than the project and bim itself.
