Through the establishment of accurate model and penetrating information transmission, Ezhou airport has completed the construction of 100000 ton steel structure of 750000 square meters transfer center in 6 months.
After 40 years of development, it has formed a number of influential benchmarking enterprises, monopoly commercial software and systematic international standards in the world.
During the 14th Five Year Plan period, the industry will add more than 30 transport airports, and more than 40 of the top 50 airports with passenger throughput need to be reconstructed and expanded.
At present, the products we use are generally commercial software developed abroad, lacking independent and controllable BIM software.
Through the use of building information model (BIM), simulation technology, digital twin and other digital means, improve the design refinement level and construction management efficiency, and provide support for scientific decision-making and management and control.
Gradually realize the full life cycle management of BIM application, and further extend to multi scene integration applications such as BIM + GIS, BIM + assembly construction, BIM + parametric design, BIM + intelligent supervision, BIM + simulation, BIM + Digital twin, so as to help the digital and intelligent transformation and upgrading of airport construction and operation.
The first is to improve the standard system and consolidate the foundation chassis.
The implementation of the 14th five year plan puts forward higher requirements for airport construction.
Carry out rapid measurement of bill of quantities based on accurate model to improve the accuracy and timeliness of process payment.
Further promoting the coordinated development of intelligent construction and building industrialization and promoting the industrialization, digitization and intelligent transformation and upgrading of civil aviation construction are not only the objective requirements for realizing the high-quality development of civil aviation and building the quality project of airport construction, but also the internal needs for changing the airport construction management mode and implementing the accurate control of engineering elements, but also the “four type airport” and “quality project” An important starting point for implementation.
Therefore, compound talents who both understand engineering and master BIM Technology are very scarce.
What is the significance of this release of the action plan? A: on the one hand, it is the starting point for implementing the new concept of civil aviation development.
I believe that in the future, with the popularization of this technology, the corresponding organization mode will be gradually optimized in place.
The application of prefabricated construction in the field of civil aviation is preliminarily explored in the construction of far stand boarding bridge and lighting bridge.
Secondly, we should increase policy support and stimulate internal motivation..
In contrast, the BIM application in China started late.
On this basis, actively participate in the formulation of international BIM standards and fill the gap of airport standards.
However, the application of new technologies often brings about profound changes in the way of organization.
We hope to gradually establish and improve the standard system of civil aviation intelligent construction, promote demonstration projects that can be copied, promote the formation of open and shared digital resources, and lay a solid foundation for the world’s leading civil aviation intelligent construction and comprehensive building industrialization.
The core content of intelligent construction in the field of airport construction is mainly digital application, intelligent construction management and assembly construction based on BIM (building information model) technology.
On the other hand, it is also an important means to meet the new development requirements of the 14th five year plan.
This article is about 2886 words It is expected to take 17 minutes to read.
The first is the lack of independent R & D capabilities and professionals.
BIM Technology began in 1980.
From the perspective of practical effect, according to the annual report of NBS in the UK, 70% of the users of BIM application believe that the investment can be reduced by 33%, and 60% believe that the construction period can be saved by 50%.
Carry out traceable project quality inspection and evaluation management in combination with on-site measured quantities.
So, what is the development background of intelligent construction and building industrialization? What is the next specific plan of the action plan? Around these issues, the reporter interviewed the relevant person in charge of the airport Department of the Civil Aviation Administration.
What is the engineering application effect of civil aviation intelligent construction and building industrialization? A: take BIM as an example.
In addition, at present, only one BIM unified application standard has been issued by civil aviation, and the standard system is not perfect; The charging standard and income distribution policy of BIM application have yet to be clarified, the lack of support for technical research and software R & D, and the lack of power of market players are also the current difficulties.
During the “14th five year plan” period, the airport construction will focus on the main line of smart civil aviation construction and rely on intelligent ideas, technologies, management and other means to realize digital drive, intelligent production, intelligent management and smooth operation of airport construction and operation.
It was not until the comprehensive application in the construction of Ezhou airport in 2019 that the digital level of the industry was promoted rapidly, which had a great impact on the domestic BIM field.
For example, Ezhou airport organized the preparation of 800000 word management manuals such as BIM management system, BIM based engineering measurement and pricing rules and digital construction control requirements in the design and construction bidding stage, requiring all participating units to carry out design and construction, achievement delivery, quality inspection and pricing according to unified and standardized operation processes, A management system has been established for the application of new technologies.
The construction practice of Ezhou airport also confirms this data index, with 10 million R & D investment in exchange for 1 billion yuan of capital reduction, and one year’s centralized BIM design in exchange for 20 months to complete the construction of 14.8 billion yuan project.
On the basis of summarizing the previous practical experience, make concerted efforts to prepare a number of technical standards, contract templates and application guidelines.
At present, only the railway BIM standard led by the railway BIM alliance has had a certain influence in the world.
On this basis, it integrates sensing equipment such as video monitoring, field monitoring radar and optical fiber sensing to realize visual simulation of operation scenarios and guide collaborative operation.
A large number of large-scale comprehensive transportation hubs with “multi terminal + multi runway” mode have been built, and a number of projects with complex construction conditions such as reclamation airports and high plateau airports have been launched, Put forward higher requirements for infrastructure construction capacity and industry management capacity.
At present, from the perspective of BIM application, cloud operations realize multi person and multi professional collaboration and improve design efficiency.
Through construction simulation and schedule management, the dynamic control of construction period is realized.
Collision inspection of different disciplines reduces errors, omissions and defects, and avoids more than 95% rework waste in traditional engineering construction.
What are the shortcomings and difficulties in the application of BIM Technology? A: Although the application of civil aviation BIM Technology has produced many benefits and shown good development prospects, it still faces some difficulties in application and promotion.
In the next step, what will CAA do to promote the coordinated development of intelligent construction and building industrialization? A: we will plan to carry out the next work from five aspects.
Compared with the railway, highway and construction industries, the application of civil aviation BIM started earlier, but its early development was slow.
Visual disclosure to the construction team, “what you see is what you get”.
Recently, the Civil Aviation Administration issued the action plan for promoting the coordinated development of civil aviation intelligent construction and building industrialization (hereinafter referred to as the “action plan”) to increase the application of intelligent construction and building industrialization in all fields and links of civil aviation construction.
Integrate with the new generation of information technology to realize video monitoring and 7 × 24-hour quality and safety supervision, non-stop construction personnel and clearance management.
What is the meaning of intelligent construction and building industrialization? What is its development process in China? A: intelligent construction and building industrialization mainly include digital design, intelligent construction management, intelligent engineering equipment and intelligent production.
From the perspective of government supervision, remote real-time intelligent supervision such as project construction quality and safety, migrant workers’ wages, project fund use and project audit through port access will greatly improve the effectiveness of supervision and solve the shortcomings of insufficient supervisors, insufficient funds and insufficient means.
Moreover, BIM Technology integrates multi-disciplinary knowledge such as engineering, management, it and logic, and has a high technical threshold for understanding and mastering.
From the perspective of airport operation, the accurate BIM model builds a digital chassis for building smart airport collaborative decision-making.
