1, virtual construction, scheme optimization;
Firstly, the construction models of virtual construction, construction process control and cost control are established by using three-dimensional modeling and building information model (BIM) technology, and virtual construction is realized by combining virtual reality technology. Through BIM technology, the consistency of the model and the inheritability of the model information are maintained, and the effective integration of all stages and aspects of the virtual construction process is realized. Secondly, the model combines optimization technology to experience, demonstrate and optimize the scheme in an immersive way. Thereby improving the construction efficiency and the safety of the construction scheme.
2. Collision inspection to reduce rework;
In the virtual three-dimensional environment, it is easy to find the collision and conflict in the design, and quickly, comprehensively and accurately check out the mistakes and omissions in the design drawings and the collision between disciplines before construction, thus reducing the rework in the construction.
3, image progress, 4D deficiency;
By linking BIM with construction progress, spatial information and time information are integrated into a visual 4D(3D+Time) model, which can intuitively and accurately reflect the construction process and virtual image progress of the whole building.
4. Accurate calculation and cost control;
The combination of engineering quantity statistics and 4D schedule control is the so-called 5D application of BIM in construction. BIM is a database with rich engineering information, which can truly provide the engineering quantity information needed for cost management. With this information, the computer can quickly carry out statistical analysis of various components, and it is very easy to realize the complete consistency between the engineering quantity information and the design scheme.
5. Field integration and collaborative work;
The application of BIM technology is more similar to a management process, and its application scope involves the cooperation of owners, design institutes, consulting units, construction units, supervision units and suppliers. In the process of project operation, it is necessary to take the BIM model as the center and let all participants work together in model, data, management and operation.
6, digital processing, factory production
Building industrialization is the combination of factory prefabrication and site construction, which will be the development direction of the future construction industry. BIM combined with digital manufacturing can improve the production efficiency of contracting engineering industry. Realize the automation of building construction process.
7. Visual Construction and Integrated Delivery (IPD)
With the gradual maturity of BIM technology as a building information mode, IPD (integrated product development), a new way of integrated delivery of construction projects based on BIM technology, is a project information means and a set of project management implementation mode summarized on the basis of theoretical research and engineering practice in order to improve the production efficiency and scientific and technological level of the construction industry. It has brought about a new project management model reform, integrated construction professionals to the greatest extent, and realized information sharing and efficient cooperation among cross-functional, cross-professional and cross-enterprise teams.
BIM building information modeling is to establish a building model based on the relevant information data of the construction project, and simulate the real information of the building through digital information simulation. It has five characteristics: visualization, coordination, simulation, optimization and drawing. Cite the definition of BIM in American National BIM Standard (NBIMS), which consists of three parts:
1, BIM is a digital expression of the physical and functional characteristics of a facility (construction project);
2.BIM is a knowledge resource shared by * *, and it is a process of sharing information about this facility in the whole life cycle from construction to demolition, providing a reliable basis for all decisions;
3. At different stages of the project, different stakeholders insert, extract, update and modify information in BIM to support and reflect the collaborative work of their respective responsibilities.
