Implementation of BIM application. So far, a considerable number of construction projects in China have applied BIM Technology. Although BIM application can bring the advantages of intuitive display and automatic inspection of design conflicts by computer, and has good application prospects, in the actual process, there are few projects actively applying BIM, especially the enthusiasm of applying Bim in design projects is relatively low, that is, there are problems in the implementation of BIM application.

Through intelligent engineering construction, we can not only promote transformation and upgrading of internal production relations in engineering construction management units, but also complete the harmonious docking with "Internet plus" social productive forces, and further release the innovative and effective vitality of employees, and provide the source of sustainable development for engineering construction management units.

From the perspective of information development, the development of information technology represented by the Internet of things, big data and artificial intelligence has provided the construction of intelligent engineering with information foundation and industrial foundation; At the same time, the increasing intelligent level of industrial equipment has also created good technical support for the construction of intelligent projects. However, looking at the information or intelligent construction of many projects, there are unsystematic, incomplete and inconsistent problems, and there is no fundamental solution to the problems of information island and data fragmentation. Therefore, to further promote the practice of intelligent engineering, we must correctly handle the theoretical relationship between information technology and management technology, adopt the two-wheel drive mode of technological innovation and management innovation, realize the perfect integration of the two, ensure the quantification and integration of business data, centralized sharing, unified decision-making platform and management intelligent collaboration.

5g technology is used for automatic collection and transmission of big data. There are requirements for big data collection in the engineering construction industry. For example, the Internet of things is used to collect health detection data of large structures such as bridges and tunnels for analyzing the reliability of structures. Although in theory, 5g technology has no problem in the automatic collection and transmission of such big data, it will encounter some obstacles in the actual process. For example, 5g requires more intensive base station layout. The practical problem is how to arrange 5g base stations in remote areas to meet this requirement?

Big data applications. So far, it has been concluded that there are a lot of data in the engineering construction industry, but there is no big data. The key problem is that the data is scattered in different government departments, different enterprises, and even different enterprise departments or projects. With the application of 5g in automatic data collection and the digital transformation of enterprises, the value of big data analysis will receive extensive attention, and the research on the application of big data in engineering construction industry will be put on the agenda. The focus of big data application will be on the acquisition and management of big data and big data application points.

So far, the application of data mining technology has effectively supported enterprise management decision-making. The development of big data application research will raise the level of enterprise management decision-making support to a new level. It is also essential for enterprise digital transformation.

In China's engineering construction industry, the localization of graphics platform has attracted attention more than 30 years ago. Relevant national departments have given subsidies and support in several "five-year plans", but this problem has not been solved so far. A similar problem is the localization of BIM platform. At present, BIM application is in full swing, but all the basic software such as BIM modeling used are products provided by foreign manufacturers.

The technical problem of "neck sticking" caused by the Sino US trade war calls us to pay attention to the localization of graphics platform and BIM platform in engineering construction industry. Fortunately, this issue has attracted the attention of relevant departments, and has begun to organize scientific and technological projects for research and development.

"Smart project" is an industry manifestation in the field of engineering construction. It is a new concept of project life cycle management. It uses Beidou navigation and positioning system, various sensors, data transmission terminals and other Internet of things means to obtain project construction process information, upload it to the cloud platform to ensure data security, and accurately design and simulate the project with Beidou Positioning System and BIM Technology to reduce construction errors and repeated construction. This data is used for data mining and analysis with the engineering information collected by the Internet of things in the virtual reality environment, providing process trend prediction and expert plan, and transmitting important information to relevant personnel through mobile phones, alarms and other terminals, so as to realize the visual intelligent management of the project, so as to improve the informatization level of project management and improve the project quality.
