.
At present, the application of BIM Technology in building engineering is gradually increasing
.
How to use BIM Technology to improve fire design, construction acceptance, fire safety management, and then Improve the overall fire safety level of buildings? 1
.
Compared with traditional CAD drawing, BIM model is a highly visual tool for fire design review
.
Construction project reviewers can view professional 3D models from any angle
.
With BIM model, reviewers can focus more on technical review and improve the efficiency and accuracy of design review
.
The traditional audit mode needs to measure the parameters of fire separation between buildings, fire lane width, turning radius, site slope and so on one by one
.
Through the BIM model, the auditors only need to set reasonable audit rules, and the software can automatically calculate the corresponding parameter indexes and compare with the set limit value of the specification, and automatically mark the design that does not meet the requirements, greatly simplifying the review flow To improve the efficiency of examination and approval

Fire design optimization with the increasing demand for the scale of engineering construction projects, the pursuit of structural form and building appearance is more complex, enterprises and projects are facing huge risk problems, especially fire risk
.
For example, some large commercial complexes often need to set a large number of atrium shared space to create a spacious and bright shopping space
.
Architects can also use BIM model to analyze and optimize the fire compartment division, evacuation corridor width and stair position, which greatly improves the quality and efficiency of fire protection design
.

.
Special fire protection design analysis with the rapid development of China’s economy, in recent years, there have been large-scale transportation hubs such as urban complex, terminal building and so on
.
These buildings have the characteristics of huge volume and space due to the need of use function, so it is often difficult to carry out fire protection design according to the current specifications
.
This kind of buildings usually need to adopt performance-based fire protection design method, through software fire protection Simulation to analyze the safety of the building
.
BIM model is a kind of component in digital architecture, in which virtual building components are used to express real buildings
.
All contents exist in the form of unique components, such as walls, beams, floors, roofs, doors, windows, etc
.
Each component has its own size and information content
.
Building information model is directly transformed into fire model to improve the accuracy and credibility of software simulation of fire, and greatly save the time of secondary modeling and improve the efficiency of modeling

Assist the later fire operation management
.
There are two most serious problems in the fire operation management at the present stage: the problem of “information disconnection” in the operation stage and the early stage, and the problem of “information island” between the data in the operation and maintenance process
.
In the design stage, there is a set of fire protection design concept and strategy, and in the operation stage, there is another set of concept and strategy
.
For large construction units such as airports, railway stations, amusement parks and other crowded places, fire operation and management need to face a variety of departments, often unable to communicate in time in emergency
.
The building information stored in BIM model includes not only the geometric information of the building, but also a lot of building performance information
.
Using this model, the building information in the early stage of operation can be directly transferred to the operation stage
.
According to the management requirements of the specific operators, an operation platform based on BIM model is created, which stores all the data information in the operation process, and the fire operation management system is established The management department can customize the following applications based on BIM Technology according to the actual needs: 1) the state monitoring linkage control of fire-fighting equipment establishes a unified communication interface through the third-party equipment to collect the operation parameters and state information of all fire-fighting equipment in the building, such as the pressure of fire-fighting water supply pipe network, fire-fighting power supply equipment, and the operation parameters and state of fire-fighting water pump / fan, etc., which are completely and accurately recorded The BIM is stored in the management platform for the convenience of all professional operators
.
2) The simulation analysis of fire conditions is a necessary link in the digital plan making, which is used to simulate the process of fire occurrence and evacuation in buildings
.
At the stage of building fire protection design, the building fire scene simulation has been carried out, and the simulation results can be used directly
.
In the process of building use, if the building structure, function and building materials change, the emerging database can be updated synchronously, and then the fire scene simulation becomes more convenient
.
3) BIM virtual reality technology is used to provide multi-dimensional expression for digital plan
.
The process of building fire simulation can be displayed intuitively, so that the public can quickly understand and be familiar with the plan
.

.
To assist the fire rescue command and shorten the time for firefighters to arrive at the fire scene is the key to extinguish the initial fire of large public buildings and prevent small fire from causing major disaster, which is particularly important for large public buildings with dense personnel
.
As a key unit of fire protection, large public buildings enter the fire state
.
After extracting the building spatial structure from BIM database, the urban fire command center can display the building location, surrounding road conditions, fire lane, fire pump location, fire alarm location and other information in the virtual city platform
.
BIM data format is used for information transmission and extraction
.
The rescue information can be quickly and losslessly transmitted between various platforms, and the relevant rescue personnel can directly view the required content through BIM model
.
The application of BIM Technology in construction engineering enables all kinds of information to be transmitted and consulted quickly and accurately, further shortens the time for fire alarm, fire department to receive and dispatch the alarm, and rescue personnel to arrive at the scene for rescue work, and improves the ability of command center to receive the alarm quickly and the fire rescue efficiency of fire forces
