Introduction. Development and widespread dissemination of information technologies, including the Internet, mobile communications, cloud computing, Big Data, the Internet of Things, digital twin, etc. are being proactively introduced into versatile production and business processes of the construction industry. Therefore, a graduate of a civil engineering university must master the fundamentals of the above-listed technologies and know how to use them in his/her practical activities. It’s particularly important for those specialities that deal with information technologies in civil engineering. However, a number of important areas of knowledge that serve as the basis for mobile communications, the Internet, and wireless technologies, are only taught at specialized universities and schools. Nevertheless, students of civil engineering universities need to understand the theoretical provisions and processes of information technologies. Materials and methods. Systematization, the benchmark method, theoretical generalization of data extracted from literary sources were applied. Results. The founding notions, needed to discuss digital technologies, encompass temporary signal notation, spectral characteristics, spectral bandwidth, time and frequency division, multiplexing, discrete sampling and quantization of a signal. It is impossible to successfully study and effectively use these advanced technologies without having understood these fundamental technologies. The author offers a simplified explanation of these notions and principal processes in terms of their application in the construction industry. Conclusions. The author addresses complicated issues of the theory of signals and their transmission over communication lines. He presents the three key ideas that serve as the basis for multiple advanced information technologies, including time and spectrum signal notation, time and frequency division, multiplexing, discrete sampling and quantization of a signal. The author’s ideas can be used to teach mobile technologies, the Internet, the Internet of Things, cloud and edge computing, digital twin, etc.

Nowadays, information modeling technologies have begun to develop actively. In this regard, BIM technologies are most successfully implemented in the construction industry all over the world. The paper presents various interpretations of «BIM-technologies» and analyzes the effects of their successful use. The authors propose supplements to the concept of introducing a life cycle management system for capital construction objects with the use of information modeling technology. Within one of the directions, it is recommended to integrate BIM and the Internet of Things. The article also examines the essence of the concept of «Internet of Things». An overview of IoT devices used in the construction industry in Russia and in the world is given, directions for its further improvement and practical application are determined. As a result, the paper analyses the integration of BIM and the Internet of Things in smart construction. The purpose of this study is to identify promising directions for the development of companies in the construction industry.

The construction industry is the pillar industry of China’s national economy. According to the statistics of the National Bureau of Statistics, the GDP in 2016 was 744.127 billion yuan, while the total construction output value was 193.567 billion yuan, accounting for 6.5 percent of China’s GDP. The construction industry has played a pivotal role in promoting social development. Construction projects have always belonged to typical high-risk industries, and they will be affected by many factors, and these factors are mostly from the social environment and the natural environment, which makes it difficult to realize the expected construction period, cost, quality, safety, etc., of the construction project. The objectives, especially for large- and medium-sized construction projects, involve a lot of specialties, a wide range, a long construction period, and a huge amount of investment. Once the risks appear, the consequences are unimaginable. In addition, construction projects will be affected by accidental factors during the implementation process. If not handled in time, it will seriously affect the normal operation of construction projects. In view of the above problems, this article aims to study the risk management research of construction project management under the multimedia environment of the Internet of Things. Combining the characteristics of mobile construction projects, various problems are analyzed in the construction process of construction projects. This paper proposes a multimedia-based construction project management system, construction project quality management objectives and principles, and schedule risk prediction. The experimental results of this paper show that taking the construction project under the multimedia environment as an example, the communication management and quality control management of the construction project under the multimedia environment are studied. Through the combination of theory and practice, the work of construction projects under the multimedia environment of the Internet of Things is guaranteed to be completed on time and with high quality.

The existing stand-alone multimedia machines and online multimedia machines in the market have certain deficiencies, so they cannot meet the actual needs. Based on this, this research combines the actual needs to design and implement a multi-media system based on the Internet of Things and cloud service platform. Moreover, through in-depth research on the MQTT protocol, this study proposes a message encryption verification scheme for the MQTT protocol, which can solve the problem of low message security in the Internet of Things communication to a certain extent. In addition, through research on the fusion technology of the Internet of Things and artificial intelligence, this research designs scheme to provide a LightGBM intelligent prediction module interface, MQTT message middleware, device management system, intelligent prediction and push interface for the cloud platform. Finally, this research completes the design and implementation of the cloud platform and tests the function and performance of the built multimedia system database. The research results show that the multimedia database constructed in this paper has good performance.
