Why build a new ecology of the construction industry Internet platform?

The "Guiding Opinions on Promoting the Coordinated Development of Intelligent Construction and Building Industrialization" proposes that by 2025, the policy system and industrial system for the coordinated development of intelligent construction and building industrialization will be basically established, the level of building industrialization, digitization, and intelligence will be significantly improved, and the construction industry Internet The platform is initially established.

Empowering all parties in the industrial chain to promote industrial transformation and upgrading

At present, there is no unified definition of the construction industry Internet platform nationwide. "China Construction Industry Informatization Development Report (2021) Intelligent Construction Application and Development": In the Internet chapter of the construction industry, according to the development trend and requirements of the digital transformation of the construction industry, its definition is innovatively proposed. We believe that the construction industry Internet platform integrates cutting-edge digital technology and advanced lean construction theory and methods, runs through the entire process of the project, upgrades all elements of the industry, connects all participants in the project, and provides virtual construction services and virtual-real twin construction services. To achieve the optimal allocation of resources in the entire industry chain, maximize production efficiency, and empower all parties in the industry chain. The construction industry Internet platform brings together construction enterprise organizations and units through "collaboration, empowerment and symbiosis" to play the role of sharing resources, attracting and complementing each other, forming a community of collective interests, and providing a one-stop solution for construction industry enterprises. Digital, networked, and intelligent services will boost the transformation and upgrading of the construction industry.

According to the application scenarios, the construction industry Internet platform can be divided into four levels: supervision layer, industry layer, enterprise layer and project layer. Each level can be specifically expressed as:

(1) Regulatory level. The supervision-level construction industry Internet platform is to use the software of construction technology to connect with the existing systems and standards, relying on the construction industry Internet to monitor the core data of the industry, to establish a full-process intelligent supervision platform, from design, production to construction, assembly and acceptance. Focus on monitoring safe and civilized construction and construction site management, real-name management of construction workers, management of environmental protection measures at construction sites, etc., serving government decision-making analysis, and helping to achieve precise policy implementation and precise scheduling.

(2) Industry level. The industry-level construction industry Internet platform is oriented to the whole link of the construction industry, providing enterprises with full life cycle management and services of construction products such as survey, design, production, construction, and operation. Through the construction of industry-level Internet and identification analysis industry node system, the data circulation and collaborative management of the whole process of architectural design, production, transportation and construction are opened up; guided by market demand and supported by data sharing, a new industry ecology and flexible Upstream and downstream relationships, boost the transformation of the construction industry.

(3) Enterprise level. The enterprise-level construction industry Internet platform is to open up enterprise resources and capabilities around the ecological circle of the upstream and downstream industrial chains of the enterprise. In the links of production and construction, it collects all-factor information in the process of engineering construction, and calculates the information transmission through network information technology. The construction industry Internet provides data sources. At the same time, with the help of visualization methods, the entire project process is visualized, and key nodes are tracked and monitored to ensure project quality, safety, progress and cost control objectives, and to meet the digital, networked, and intelligent upgrade needs of enterprises.

(4) Project level. The project-level construction industry Internet platform is to provide enterprise digital transformation services in a lightweight way for specific links or specific scenarios such as survey, design, production, construction, and operation.

The digital transformation of the construction industry is a process of continuous in-depth and evolutionary development. Under the empowerment of the construction industry Internet platform, the construction industry Internet platform can have an in-depth impact on the construction industry, which is “vertical to the end and horizontal to the edge”. Specifically, it can be divided into There are five aspects: First, digitize the job layer to improve the efficiency and quality of each job layer. The second is to digitize all "lines" of engineering project management such as production, business, and technology to achieve lean management of projects. The third is to open up the business flow, information flow and capital flow of the enterprise layer, optimize the resource allocation of the industrial chain, and realize the intensive operation of the enterprise. Fourth, it is conducive to building a supervision service platform and supervision system, providing supervision services such as healthy market supervision, efficient on-site supervision, health integrity system, and labor training. Fifth, it can effectively promote the reform of the construction industry and the innovation of systems, mechanisms and models, and accelerate the realization of high-quality development of the construction industry.

In terms of the construction and in-depth application of the construction industry Internet platform, Sichuan Huaxi Group has some relatively good explorations. The Huaxi Group's digital construction supply chain platform was analyzed by the Ministry of Housing and Urban-Rural Development as a successful case of industrial Internet. The platform is an industry ecological platform that brings together construction industry procurement units, supply units, financial institutions, industry associations and other industrial chain units. It provides users with procurement plans, bidding, encrypted bidding, contract signing, order performance, settlement through cloud deployment and SaaS model. Full-chain digital solutions for supply chain such as payment and financing promotion, realize data security, trust, irreversible push of digital supply chain through technologies such as blockchain and big data, and provide industry reference index. At the same time, the platform pioneered the technical architecture of "one network, three libraries, and multiple systems" in the construction field, developed more than 800 system modules, realized more than 13,000 functional requirements, and provided more than 50 large-scale enterprises and more than 100,000 supply units in the industry. Chain integration services, the annual transaction volume exceeded 60 billion yuan.

 

Building Industrial Internet Thinking

 

The Internet of the construction industry has developed to this day, and there are not many platform construction applications that really stand out, and even fewer cover the entire industry chain of the construction industry. The reason is largely because the main business contents and production organization forms of different enterprises in the construction industry are very different. Large, product and project processes are very personalized, it is difficult to use a standard to unify. As a result, the development of Internet platforms by enterprises is often based on their own business logic. The Internet was originally intended for information interaction, but it only achieved the transfer of traditional business processes to the Internet, which made little contribution to efficiency improvement and process optimization.

Summarizing the development level of the construction industry and enterprises at this stage, we believe that building an Internet platform for the construction industry may face the following four challenges:

(1) Informatization level and construction cost. The premise of the development of the Industrial Internet is the full cycle, all elements, and all roles to "connect to the Internet", which will inevitably require a lot of software and hardware cooperation. The construction industry is on the road from extensive expansion to refined development, but there are a lot of problems of huge volume and unbalanced development.

(2) Standardized base construction. At present, the informatization of the construction industry is insufficient, and the full life cycle management based on the BIM model has not been popularized and realized. There is still an urgent need to establish equipment standards, data standards, algorithm modules and operating specifications for the implementation of the Industrial Internet.

(3) Data security and network operation guarantee mechanism. Big data and cloud computing are the basis for the realization of the Industrial Internet, and the construction industry has not yet established a guarantee mechanism based on data security and smooth network operation. The construction industry has a relatively mature operation model, but based on the traditional operation model, the industrial Internet cannot be truly realized, and the effect of the fission-type growth of the industrial Internet cannot be realized. It is more important to break the obstacles of the mechanism and fundamentally establish the industrial Internet thinking.

(4) The "big leap" development trap. The development of intelligent construction and the construction of industry informatization are staged, and need to go through the stages of digitization, networking, and intelligence, and must be gradually improved in stages. To achieve equipment interconnection, data collection, task process improvement, smooth upstream and downstream information, data integration and integration, mining and analysis, etc., intelligent construction can only be achieved through coordination.
