Practice the digitalization of the whole process of BIM and develop its own and easy-to-use top software

The construction of Guanglianda South China Headquarters Base adopts the EPC (General Contracting) model and integrates BIM (Building Information Modeling), prefabricated, green construction and other construction technologies, which is a comprehensive practice of the concept of "digital architecture".

Yuan Zhenggang, chairperson and president of Guanglianda Technology joint stock company, said that this project is one of the few typical projects in the construction field that uses completely self-developed domestic BIM software and platform to empower the whole life cycle of the construction industry. The main purposes of the whole process of BIM application practice include: first, to solve the problem of data standardization and integration; second, to promote the refinement of project management through the structuring of the business; third, to continuously improve the value of products through the deep integration of the business team and the software team, and to polish the top software that belongs to the Chinese people. This is the responsibility of Chinese technology companies and the glorious mission of helping the digital transformation of the construction industry.

In the whole process application of domestic BIM in Guanglianda South China Headquarters Base, based on the analysis of the business essence logic of the whole process of the project, identify the core business scenarios and build models and data unit frameworks accordingly to ensure the consistency and smooth flow of business, data and models. Through the digital analysis of business, the design, cost, production, quality, safety and other information are exchanged and shared, the mapping is established and the circulation is realized, and the business value scenario based on the BIM model is designed.

Facing product design, the project drives the response of building functions and the design of building modules and systems through the analysis of building product requirements. Each professional design determines the corresponding building standards, system configuration standards, product standards, and composition practice standards according to the splitting of modules and systems. With the help of localized BIM software integrated design and cost model, different design schemes and cost data are linked to determine the optimal product composition scheme and cost subject standard, and realize integrated forward design to ensure that the owner’s needs are met.

Facing engineering construction, through the detailed analysis of planning, safety and quality management and public resource management, and taking engineering tasks as the basic unit, the construction management planning focusing on time, space and people based on BIM model is realized. During the construction process, the integration of IoT (Internet of Things), AI (artificial intelligence) and other technical means, real-time and dynamic collection of human, machine, material, method, ring and other element information, to create a digital command cabin of intelligent construction site with digital-model linkage and virtual-real combination, tracking the status of the project site, and providing support for project decision-making.

Facing the construction operation and maintenance, the project first identifies and analyzes the needs of each major under different operating conditions during the design process, and avoids redundant and unreasonable system configuration in the design of each major. At the same time, the building requirements and standards, system configuration parameters, operation logic and operation strategy are integrated into the BIM model to ensure the complete undertaking of the operation and maintenance stage and the effective execution of the design intention. During the operation process, the operation strategy is dynamically optimized through the feedback of the actual operation effect.

Taking the business value scenario of domestic BIM application as the main line, through the interoperability of the whole process, the whole business line, the whole professional model and data, the construction of Guanglianda South China headquarters base will eventually form a set of demand-oriented, design-oriented breakthrough point, supported by refined process management and control, and integrated with scientific management mode, advanced business practices and digital technology application.

Deep application of domestic design software empowers the digital transformation of the construction industry

According to Yang Wei, vice president of Guanglianda Technology joint stock company, the successful application of the whole process of digitalization in Guanglianda’s South China headquarters base stems from Guanglianda’s professional accumulation and technical accumulation for more than 20 years. Guanglianda BIM series software has covered most of the business needs of the whole process of engineering construction, and even made important breakthroughs in the field of engineering design software where foreign software has a significant advantage.

Data-driven integrated design solutions lay the foundation for the whole process of digital construction. In 2022, Guanglianda released a digital design product set. The product set is based on the independent intellectual property graphics platform and is a full-professional BIM forward design solution product. Guanglianda’s South China headquarters base adopts digital design software and collaboration platform. Through the "cloud + end" collaboration model, it realizes the forward design of BIM and multi-professional collaboration of architecture, structure, electromechanical and other majors from the scheme, construction map to the deepening stage. It realizes the flow of models and data at each stage of design-calculation-construction. Through the seamless docking of design models and calculation models, the matching mapping of design and cost at each stage is established, and the cost control from the design source is realized.

Localized BIM + IoT + AI to realize visual management. The project sets up more than 200 intelligent hardware to perceive the real information happening on site, and matches the corresponding management scenarios through information aggregation. Based on the model, time, space and people focus are realized. Through built-in AI rules, based on real-time and on-site records of the construction process, the progress, safety and quality of the project site are automatically identified. Through the combination of virtual and real on site and BIM model, the visual management and data-aided scientific decision-making of the engineering site are realized.

Digital and intelligent technology to support intelligent construction. For on-site public resources, such as tower cranes, vertical elevators, material yards, roads, etc., the project uses digital and intelligent technology to achieve fine control and ensure better and more efficient multi-professional construction distribution. Taking the tower crane as an example, the type of lifting objects and lifting actions are built into the AI algorithm to carry out ergonomic analysis. Through the time-consuming analysis of various materials in each link of hoisting, the subsequent use time of the tower crane can be reasonably anticipated to ensure the progress is controlled. The project also linked the progress plan with the BIM model to establish a quality management and safety management system based on engineering tasks.

Based on data-driven integrated design solutions, as well as localized BIM, IoT, AI and other digital technologies, Guanglianda South China Headquarters Base has opened up the digital chain of the whole life cycle of the project, allowing data at all stages to generate "chemical reactions", and building application scenarios for data-driven decision-making in the whole process, laying the foundation for fully empowering the digital transformation of the construction industry.
