Application Value of BIM Technology in Assembly

1, BIM technology in the design stage of the assembly type of value

(1) improve the efficiency of assembly-type building design

Assembly-type building design, due to the need for prefabricated parts of various types of embedded and reserved design, and therefore more in need of professional designers close coordination. Using the design platform constructed by BIM technology, the professional designers in the assembly building design can quickly transfer their professional design information and make "synchronous" modification to the design plan. With BIM technology and "cloud" technology, professional designers can upload BIM models containing their own professional design information to the BIM design platform and automatically screen out design conflicts among various disciplines through collision and automatic error correction , To help professional designers to find out the problems in the professional design in a timely manner; prefabricated components in assembly type of the type and style of a large amount of plans, through the "collaborative" BIM technology design features, a professional designer to modify The design parameters can be synchronized and invoked by other professional designers without any mistake, which facilitates the adjustment of the design scheme by the supporting professional designers and saves the time and effort spent by various professional designers due to the adjustment of the design scheme.

In addition, more skilled and managerial professionals can be involved in the design of fabricated buildings through the granting of different management and revising permissions to assembly-type building professionals, component designers, and associated technical and administrative staff , According to their own professional advice and suggestions to reduce the production of prefabricated components and assembly design changes in the construction of buildings and improve the owners of assembly-based architectural design units to improve the efficiency of assembly-type buildings to reduce design efficiency, reduce or avoid Project costs and waste of resources due to design (Figure 1).

(2) to achieve the standardized design of prefabricated assembly

BIM technology can open and share design information. Designers can upload the design of the prefabricated building to the project's "cloud" server, integrate the dimensions, styles and other information in the cloud, and build the prefabricated components (such as doors, windows, etc.) Family "library. As the "family" of cloud servers continues to accumulate and enrich, designers can compare and optimize the same family of "families" to create the standard shape and modular dimensions of fabricated building prefabricated components. The establishment of prefabricated "family" libraries facilitates the design of assembly design and design standards. Utilizing all kinds of standardized "family" libraries, designers can also accumulate and enrich the design units of the prefabricated buildings and save time and time for unit design and adjustment, enriching the size of the prefabricated buildings and better meeting the diverse needs of occupants demand.

(3) reduce the design of assembly-type building error

Designers can use BIM technology to fine-tune the fabricated building structures and prefabricated components to reduce assembly bias that can easily occur during the construction phase of fabricated buildings. With the aid of BIM technology, the geometrical dimensions of prefabricated components and the inner diameter of rebar, spacing, the thickness of the steel bar and other important parameters for accurate design and positioning. In the 3D view of the BIM model, designers can intuitively observe the fit between the prefabricated components to be assembled, and can utilize the collision detection function of the BIM technology to analyze the reliability of the prefabricated component connection nodes in detail and exclude the prefabricated components So as to avoid the installation design of the prefabricated components due to the rough design and to reduce the construction time delay and the waste of material resources caused by design errors.

2, BIM technology in the construction phase of the application of building value

(1) improve the prefabricated parts inventory and on-site management

Prefabricated building assembly prefabricated parts production process, prefabricated components classified production, storage need to invest a lot of manpower and material resources, and prone to error. BIM technology combined with RFID technology, through the process of prefabricated components embedded in the installation site and the use of information and other components of the RFID chip, storage and inspection personnel and logistics and distribution personnel can directly read the prefabricated components of the relevant information to achieve the electronic information Automatic control, reduce the traditional manual acceptance and logistics mode of acceptance of the number of deviation, component stacking position deviation, the warehouse records inaccurate and other issues occur, you can obviously save time and cost [5]. During the construction phase of the prefabricated building, the builder uses the RFID technology to directly call out the relevant information of the prefabricated components and inspect the necessary items such as the installation location of the prefabricated components to improve the quality management level and installation efficiency during the prefabricated components installation.

(2) Improve the efficiency of construction site management

Assembled building hoisting complex, high degree of construction mechanization, construction safety assurance measures require high, before the start of construction, the construction unit may

In order to use BIM technology to simulate and simulate the construction of prefabricated building, simulate the hoisting and construction process of prefabricated structures on site and optimize the construction process, and also simulate the safety accidents on the construction site, improve the safety management plan of construction site, eliminate the potential safety hazard, Thus avoiding and reducing the occurrence of quality and safety accidents. BIM technology can also be used to optimize site layout and vehicle routing at construction site to reduce secondary handling in prefabricated components and materials, improve hoisting efficiency of vertical transport machinery and speed up the construction progress of fabricated buildings.

(3) 5D construction simulation optimization construction, cost planning

Using BIM technology, time and resource dimensions are introduced into the BIM model of the prefabricated buildings and the "3D-BIM" model is transformed into a "5D-BIM" model. The construction unit can simulate the entire prefabricated building through the "5D-BIM" model Construction process and all kinds of resources [2], the establishment of assembly-type construction of the "dynamic construction planning", an intuitive understanding of the assembly-type construction technology, schedule and funding arrangements phase and funding; resources can also be simulated During the process, problems existed in the original construction planning were found and optimized to avoid the increase of construction cost and delay due to poor consideration. The construction simulation using "5D-BIM" enables the construction management and technical staff to have a more intuitive understanding of the entire project's construction flow schedule and cost resources investment. The management staff can optimize the construction plan and sequence in the simulation process, Arrange resource supply, optimize cash flow, and implement dynamic management of construction schedule and cost (as shown in Figure 4).

3, BIM technology in the assembly building operation and maintenance stage of the application value

(1) Improve the level of equipment maintenance and management during the operation and maintenance phase

With BIM and RFID technology to build information management platform can be assembled prefabricated building components and equipment operation and maintenance system [6]. Take BIM's data management and emergency management functions as an example
