Domestic BIM whole process application sharing

As a demonstration project of the National Digital Construction Technology Innovation Center for technology application and model innovation, Guanglianda South China Headquarters has piloted the development and application of domestic independent BIM platform software, actively expanded the application scenarios of domestic BIM software in the whole life cycle of engineering projects, and built a whole-process domestic BIM software product ecosystem, setting a benchmark and boosting confidence for industry enterprises to carry out the whole-process digital application.

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.

Reach the industry’s leading level and can be widely used

During the demonstration, the expert group conducted an on-site inspection of Guanglianda’s South China headquarters base and listened to the report on the "Domestic BIM Whole Process Application Demonstration Report". Experts attending the meeting fully discussed and reached a consensus.

The expert group believes that Guanglianda’s domestic independent BIM platform software functions meet most of the business needs of the whole process of engineering projects. Compared with the existing foreign related software, it is more in line with the actual management of domestic engineering projects and has the conditions for localization. At the same time, it has reached the industry’s leading level and has the conditions for promotion and replication. It is recommended to promote application in the industry.

The expert group gave high praise to the domestic BIM whole-process application of Guanglianda South China Headquarters Base, as a demonstration project of domestic BIM whole-process application, to achieve full-professional, whole-process business communication, data communication, and model communication.

The successful holding of the demonstration pointed out the direction for the digital application of the whole process of BIM in the construction industry, opened a new channel for the large-scale application of domestic BIM series software in the construction industry, and also established confidence for industry enterprises to promote digital transformation and start the digital application of the whole process of construction projects. With the large-scale implementation of this technology, it is bound to accelerate the development of new concepts, new technologies and new models in the industry, which will deeply empower the digital transformation of the construction industry and help the high-quality development of the construction industry.

This summer, the national tourism market recovered strongly, and the number of tourists and income rose together. Data from a number of tourism platforms show that the summer tourism market is expected to surpass the same period in 2019, and parent-child tours, study tours and summer vacations have become popular choices.

The tourism market continues to heat up.

Recently, the high temperature has continued all over the country, but Wei Qian, a tourist from Anhui, felt a rare coolness in Kunming. "The temperature here is too comfortable, which is in sharp contrast with the heat in other places." Since the beginning of summer, the average temperature in Yunnan Province is only 22.9℃, and Kunming, the spring city where the weather is often like February and March, has become a summer resort.

Not only in Kunming, but also in Yunnan, you can wander around the mountains and enjoy the coolness in summer. In Dali, at the foot of Cangshan Mountain and beside Erhai Lake, tourists punch in along the ecological corridor and feel the slow life. In the Stone Forest, where the rocks are green and the peaks are beautiful, visitors can experience the Yi culture and appreciate the wonders of nature.

Entering the summer tourist season, in addition to the traditional popular routes such as Kunming, Dali, Lijiang and Diqing, tourists from Qujing, Xishuangbanna, Pu ‘er and Baoshan also continue to increase. In the past few days, the flight take-off and landing and passenger throughput in Kunming have increased sharply. On July 14th, there were 1,005 take-off and landing flights, a three-year high and 143,800 passengers were transported. Yunnan Railway Department sent 300,000 passengers every day, a year-on-year increase of 20.6%.

"The four hotels in the park were fully booked two weeks in advance." Fu Zhixin, deputy general manager of the marketing center of OCT Fantasy Resort in Xiangyang, Hubei Province, said that since the beginning of this summer vacation, the resort has attracted a large number of foreign tourists. "It is estimated that more than 2 million tourists will be received in the summer, reaching a new high." Fu Zhixin said.

Tongcheng data shows that from July 11 to 17, the number of air ticket bookings increased by more than 120% compared with the same period in 2019, and the number of hotel bookings nationwide increased by 150.53% compared with the same period in 2019. "The summer vacation has a good start." According to Lan Xing, the person in charge of Ctrip’s air ticket marketing, the popularity of this year’s summer vacation benefits from the continuous recovery of the tourism market. The superimposed airport and airline companies continue to introduce discounts, and there are marketing activities such as live broadcast and big promotion to further stimulate passengers’ travel needs.

"From the ranking of popular starting points and destinations, Shanghai ranks among the top cities in the country." Cheng Chaogong, chief researcher of Tongcheng Research Institute, said that with the gradual normalization of the tourism market, the demand for summer tourism has been released in a centralized way, coupled with the strong recovery of student flow and parent-child tourists, and the passenger flow in summer has continued to run at a high level. Shanghai is a hot spot for summer tourism destinations and tourist sources. In the first half of the summer, the tourism market showed diversified and urban characteristics.

Research tour becomes popular in depth.

"Parent-child research is a hot topic in the summer tourism market in Shanghai." Cheng Chaogong introduced that since July, the attention of "research" products in the Shanghai area of Tongcheng Travel Platform has increased by 183% from the previous month. The high temperature weather for several days in a row has stimulated the study tour of the museum, and the cool and refreshing museum has attracted many parents and students.

In view of the "bursting" of the passenger flow in major museums, Shanghai Culture and Tourism Bureau announced that it would organize 17 museums including Shanghai Museum, Shanghai History Museum and World Expo Museum to carry out "Museum Wonderful Night" activities, and pilot licensed tour guides to take groups to explain and other measures to meet the diverse needs of tourists.

The research tour is not only hot in Shanghai. The research team of Shanghe children’s theme "The world is a textbook" also arrived in the Three Gorges Dam tourist area in Yichang, Hubei Province in July. In the Three Gorges Project Museum, Dou Xin, a visiting professor at China Communication University and an ambassador for cultural exchange of the national multi-functional economic and trade platform of the Shanghai Cooperation Organization, took the history and poems related to the Three Gorges as an index and gave a wonderful and vivid study tour class on the Yangtze River literature and history for SCO children.

Since the beginning of this year, a variety of research tour products launched by the Three Gorges Dam tourist area and Qu Yuan’s hometown scenic area have been popular, with 38,000 students and 30,000 students respectively. "From Yichang to Chongqing, it is not only a corridor of Tang poetry and Song poetry, but also a cultural enrichment place of the Three Kingdoms, and it is also the only way to appreciate the Three Gorges Dam, a big country." Dou Wei said.

"With the increasing demand for personalization and diversity of users, the travel products that used to be superficial can no longer fully attract users." Cheng Chaogong believes that only by digging deep into the needs of users and creating more tourism products with cultural connotation and humanistic spirit and more urban characteristics can the market vitality be maintained. For example, summer City walk has become a popular way for young tourists to explore the city. Wu Kang Road, Anfu Road, Yongkang Road, Fuxing West Road and Fuxing Middle Road have attracted many young people to "punch in".

Make concerted efforts to provide good service.

"Tricholoma matsutake in Shangri-La, truffles in Lijiang … There are many kinds of fungi to eat, and visitors are expected to come and experience them." Lou Kewei, deputy director of Yunnan Cultural Tourism Department, said. On the basis of market research, Yunnan Cultural Tourism Department launched 10 boutique routes, including cultural tourism integration, outdoor sports and other themes. "These 10 lines are hot-selling products that can stand the market test." Liu Zhimin, vice president of Yunnan Travel Agency Association, said.

Since the beginning of this year, Hubei Province has arranged nearly 1 billion yuan in financial assistance to promote the high-quality development of cultural tourism. Among them, 400 million yuan is used to issue coupons for cultural tourism, 200 million yuan is used to support the opening of new international routes, 153 million yuan is used to encourage travel agencies to explore the tourist market outside the province, and nearly 200 million yuan is used for publicity and promotion. At the same time, coordinate financial institutions to provide loan extension, interest subsidies and other support to cultural tourism enterprises.

Hubei Wenlv Group co-ordinates 38 scenic spots and 40 hotels to launch a series of measures to benefit the people. In Shennongjia, Enshi Grand Canyon, Jingmen Geek Park and other scenic spots, visitors can enter the park free of charge with the college entrance examination and senior high school entrance examination admission ticket. The "Tour Hubei" platform started the distribution of 2023 coupons in Xianning, and 15,000 coupons have been distributed.

Railways, civil aviation and other departments also do their best to provide services to ensure the safety and stability of the summer vacation. "Airline self-service change card" and "one-stop comprehensive service counter" … China Eastern Airlines launched a series of special services to bring passengers a faster and more convenient service experience. Yunnan Xiangpeng Airlines has increased its capacity adjustment, and actively responded by thickening safety management and strengthening skills upgrading. China Railway Kunming Bureau Group Co., Ltd. scientifically allocates transportation capacity to meet the travel needs of passengers, and actively innovates service measures to enhance the travel experience of passengers.
