On April 22, a delegation led by Li Ting, a national engineering survey and design master and chief expert of Central South Architectural Design Institute, and Dr. Zhang Shen, the digital director of the company and director of the engineering digital technology center, were invited to carry out a special training report on intelligent construction within the enterprise in the lecture hall of CSCEC Optics Valley Star in Wuhan, and conduct a special exchange on intelligent construction and new quality productivity.

Li Ting analyzed and introduced the exploration and practice of Central South China Construction Institute in the aspect of "one model and no drawing construction" with the title of "Learning high-end manufacturing to promote the coordinated development of intelligent construction and building industrialization".

He quoted the sentence "It is already a cliff with a hundred feet of ice" in "Bu Operator · Yong Mei" to vividly describe the severe challenges facing the current construction industry. Li Ting said: "The core reason for this dilemma is that the construction industry has not made creative scientific and technological breakthroughs, substantive business model breakthroughs and fundamental ideological and conceptual breakthroughs in the past 30 years."

He introduced the concept of product lifecycle management (PLM) in the manufacturing industry, and the DFX concept for the whole process design, namely Design for X, where X represents each stage of the product life cycle, such as manufacturing. "We should introduce the PLM concept of the manufacturing industry, establish a cloud based collaborative design platform, achieve cross professional, cross enterprise and cross regional collaborative work based on the same 3D digital model, and achieve seamless connection from design to production and construction units with the help of advanced technologies such as MBD and evolutionary design, and integrate product design (DFC, Design for Customer) It is integrated with DFMA (Design for Manufacturing and Assembly). "

He analyzed the relationship among intelligent construction, digital construction and physical construction. It is pointed out that digital construction is the construction completed in the digital world, the process of building a digital sample room (DMU), and the mapping and digital twin of the physical construction process in the real world. He pointed out that the essence of intelligent construction is the software based industrial construction technology and the production relations defined by software, as well as the optimization and reconstruction of productivity and production relations caused thereby. Intelligent construction is defined by software and digital models, and is mainly completed by intelligent machines in factories and on the spot.

Li Ting said: "The key to realizing the choke point of digital technology in intelligent construction and building industrialization is to learn high-end manufacturing, introduce the digital design and management system (PLM) throughout the whole process of the project, introduce the digital delivery system (MBD) throughout the whole process of the project, and realize the construction (VDC) based on numerical simulation and digital twins in all disciplines."

"The introduction of DFX concept will bring a new business model to the design institute. At present, architectural design institutes generally adopt the model of providing services for the construction party and charging the construction party. DFX is to provide services for all links of the product life cycle, such as manufacturing, installation, reliability assessment, carbon emission assessment and various special designs, to achieve specific links (X) And charge specific users (X), carry out special design and implement special charges. " Li Ting said.

Taking Wuhan New Generation Weather Radar Project, Hubei Provincial Center for Disease Control and Prevention, and Zhongxiang Science and Technology Museum Project as examples, Zhang Shen showed how Central South China Academy of Construction learned from the PLM concept of high-end manufacturing industry to build a PLM platform for building life cycle management. Through MBD technology, the seamless connection between upstream and downstream of the project is realized with the unified 3D digital model as the link, creating a new chapter of construction without drawings. He emphasized that the core idea of "one model to the end" is that all parties share the evolutionary 6D digital model to work together to ensure data consistency and solve the problem of fragmentation. Looking forward to the future, the Central South Construction Institute will continue to promote the digital process of the AEC industry through project iteration and lead the construction industry to achieve digital and intelligent transformation.

The report triggered a warm response at the scene. The delegates said that through this report, they had a deep understanding of the latest breakthroughs in intelligent construction and new quality productivity in the construction field. These cutting-edge technologies opened new ideas for the digital development of the construction industry. In the future, they will carry out in-depth cooperation with the Central South China Construction Institute in intelligent construction and other fields, Jointly promote the industrialization and intelligent process of the construction industry.
