The article presents an analysis of project management in terms of the construction industry. The specific features of the management of production activities of construction enterprises have been studied and the effectiveness of this management has been determined. The main problems in the field of project management of construction activities are identified, the main of which is the absence in Russian legislation of a single normative act regulating the development and implementation of a project only in the construction sector. The project management methodology was also considered, using the example of the American methods PMBOK and PRINCE2. The authors analyzed the statistical data of domestic companies involved in the development and management of projects in various industries. The results of the study showed that Russian construction companies are not actively involved in project management compared to organizations in other areas of activity.

Information modeling of construction processes should be attributed to the actual problems of development of technology and organization of construction. An important part of the information model is the geometric description of the technological sites (excavator faces). When designing technological sites (faces) of excavators, it is recommended to use the maximum digging radius on the ground surface as a criterion, taking into account the conditions of work (types of soil). To calculate the minimum value of the digging radius, a mathematical expression is proposed, which contains a complex indicator describing the physical and mechanical characteristics of the soil (tga). The results obtained allow us to cut off earthmoving machines at the decision-making stage by the size of the maximum digging radius on the earth's surface. These results describe the first step in the information modeling of the process of excavation by an excavator.

Currently, high pressure sodium lamps are the light source in greenhouse vegetable growing. The most promising sources of artificial lighting are LED-based irradiators. They can provide a cooler temperature environment to bring plants closer to plants. The aim of the study is to determine the economic life of sodium and LED light sources in greenhouse vegetable growing, taking into account their degradation for the harvest. LEDs, like sodium lamps, degrade during use. This leads to a decrease in the light (photosynthetic photon) flux of light sources and, as a result, to a decrease in yield. Due to this certain functional dependence on the luminous flux level, the economically feasible life of the light is predicted.

Against the background of the explosive development of modern technologies and methods of construction, the use of innovative structural materials, the growing volume of information about construction production, the complexity and uniqueness of projects, and given the low tendency for retraining of personnel and the insufficient competence of the labor force involved in the production of work, the issue of the quality of construction assembly work (CMP). The applied methods of organizing construction control according to the existing and slightly modified methods of the 80-90s of the XX century do not provide the necessary level of control of construction and installation work. Given the relevance of this problem, the question arises of the need to ensure high-quality and effective construction control to exclude the facts of violation of the production technology, prevent a decrease in the operational characteristics of the building, minimize the cost of eliminating errors, etc. Using comparative, statistical methods of research, analysis and modeling of mechanisms used by engineers of construction control of Russian and foreign construction organizations, the need for implementation was justified and a method of construction control based on modern achievements in engineering and technology was proposed, in particular, the use of building information modeling (BIM) and virtual reality (Virtual Reality, VR) technologies in the relationship, which allows to increase the efficiency of construction production and control, optimize the time for analysis and management decision-making, reduce the likelihood of violations on construction sites that affect the implementation period, cost and quality of the project.

The negative trends in the country's economy associated with the COVID-19 pandemic have also affected the construction industry of the Russian Federation. The impossibility of transferring construction to a remote mode, the suspension of the work of construction companies affected their financial activities. In addition to government support, construction companies must independently seek ways to improve their performance. One of the ways to improve the quality of management in the implementation of investment and construction projects is to use the approach of integrated project implementation. Within the framework of this approach, it is necessary to focus on quality management at all stages of the life cycle. It is proposed to use this approach in conjunction with the methods of business information modeling technology for projects.

The use of mulcher machines is a promisingmethod of preventing and combating forest fires. Whenpreparing forest areas with the use of mulcher machines the soil is crushed altogether with the vegetation growing on the surface, roots and otherwood inclusions, while the process of interaction of the working body with the soil requires significant energy costs. The analysis of the mulcher operating modes with a working body in the form of a drum-chopper has been carried out and, as the result, the operating modes of the mulcher machine have been determined. The mulcher machine operation mode when cutting woody vegetation has been examined. A computer program has been developed to determine the rational parameters and operating modes of the mulcher machine.

With information modeling of buildings, the time and money spent on creating a building project is significantly minimized, and it also becomes possible to make changes to the project, reducing the likelihood of a designer making a mistake. However, building information models have a number of disadvantages expressed at each stage of the object's life cycle. In this article, the main stages of the life cycle of a building were highlighted, according to regulatory documents. The drawbacks of using information models at each stage are highlighted and their influence on the work in the information modeling environment is considered. Ways to minimize these shortcomings, taking into account the prevalence of BIM-models of the building at the present time, are proposed. The general problems of transition from the classical design method to information models are highlighted.

On November 10, 2017, new requirements came into force that apply to lighting devices and electric lamps used in AC circuits. In connection with the newly introduced requirements, calculations of power consumption in educational institutions were carried out at different times of use of the lighting load. The purpose of the research is to determine the payback period for the implementation of LED lamps instead of fluorescent lamps for various types of premises in educational institutions. The analysis of technical characteristics of LED light sources offered on the market of the Russian Federation is carried out. Based on the results of the calculations, the payback periods were obtained for the introduction of LED lamps instead of fluorescent lamps for public premises, laboratories, training workshops, as well as lecture halls of educational institutions, with different times of use of the lighting load. This can allow already at the design stage to evaluate the effectiveness of the implementation of the selected light sources.
