Remote control of construction equipment makes it possible to increase the efficiency of the workflow: reduce the construction time, adhere to a clear schedule, keeping up with the deadlines set and approved by the project, allows you to "see" the production process from different sides, eliminating almost all possible problems. Also, the full or partial transfer of authority to computer technologies guarantees continuous work in the presence of various climatic and social factors that slow down or stop the schedule. This article examines the experience of implementing remote control of construction equipment at oil production facilities. A comparative analysis of the automated and standard workflow is carried out on the example of KAMAZ trucks. The prospects for the introduction of remote control technology for construction equipment at fields in Russia in order to increase the efficiency of construction production are considered.

When clearing territories for the construction and / or subsequent maintenance of such infrastructure facilities as construction sites, airfield territories, right-of-way for roads and railways, heat supply routes, and so on, work is often carried out to remove growing undesirable tree and shrub vegetation, At the same time, the problem of assessing the quality of the performance of these works is relevant. The authors of the article consider the issues of mathematical modeling for assessing the quality and effectiveness of the work performed to clear the territories of a number of the above infrastructure facilities, give the boundary values ​​of the criteria for assessing the quality of the measures taken to remove vegetation, and formulate a conclusion about the advantages of the developed mathematical model.

Winter roads are winter roads that are temporary in nature and their construction takes place directly from the snow cover. Complex construction of roads with the use of optimizations created for temporary and economic efficiency, improving the quality of the final result, will increase the effectiveness of decisions made during the construction of winter roads. Improving the efficiency of detailed factors in the construction of winter roads, which affect the result of further work of calendar construction, will allow for faster delivery of materials, personnel and equipment to hard-to-reach objects, within the conditions of the Far North. Winter roads are the most profitable solutions in tundra conditions, since the method of using air transport to deliver materials, equipment and workers is economically unprofitable and less safe. Therefore, the timely construction of winter roads is so important for remote regions.

On the example of the construction complex of the cities of the Urals, the main types of construction defects of cast-in-situ structures of civil buildings, as well as the most characteristic causes of their occurrence, are revealed. It is established that the causes of the majority of construction defects in cast-in-situ structures of civil buildings have an organizational and technological nature. As a result of the expert assessment carried out by the method of a priori ranking of factors affecting organizational and technological solutions, a group of factors was determined, the management of which will allow the contractor to improve the quality of construction work on the construction of a cast-in-situ skeleton of a civil building. It is recommended to plan quality management measures for the construction of cast-in-situ structures of civil buildings taking into account these factors. These factors should also be taken into account in organizational and technological design, especially when developing processing slates.

In the past few years, such objects have begun to be taken outside the city limits and rebuilt in new, undeveloped territories. And on the vacated territory, a new development begins with the intensive development of underground space. The strategic innovative approach to the implementation of projects for the development of the modern city released by the industrial territory is an urgent answer to the question of a completely new understanding of the comfortable environment, in which everything is involved: zoning of the development territory, laying new roads (city streets), underground structures and communications, transport accessibility, environmental friendliness of construction. Without understanding that the problem of forming a living space is complex, in the end, comfortable conditions of human existence will not be obtained. Various modern green building standards are based on this.

Reconstruction of industrial enterprises is a complex, time-consuming and expensive process. When implementing it, a number of significant problems arise that must be taken into account at the design stage. This will allow us to find approaches to solving the problems of reconstruction of industrial production carried out under various conditions and significantly reduce the costs of construction work. Reconstruction also has three main directions, covering certain tasks and differing in the scale of reconstruction activities. One of these areas is revitalization. When there is a need to solve problems focused on the socio-cultural life of the population on the territory of the existing urban development, revitalization becomes the optimal and modern way of solving. The result of the reconstruction should be an increase in production capacity and profitability of enterprises, a reduction in the negative impact on the environment, as well as an increase in social comfort in residential areas of cities.

To date, the construction of high-rise buildings is the highest priority in construction. One of the problems in the construction of high-rise buildings is wind loads, which have a significant impact on horizontal movements. The article provides a calculation in the LIRA CAD software package of a high-rise building for wind loads in order to determine the optimal locations of outrigger floors and the type of outrigger floor. The system of outrigger floors serves to reduce the displacement of floors from the effects of wind loads.

The study evaluated the effect of the spring position in the panel on the amount of force required for vertical pushing of the columns. The results show that the farther the spring is from the hinge, the less pushing force is required to lift the column. In this method, the column was connected to the panel by hinged hinges at the factory, which allows lifting elements by crane as a single group during the installation of the frame structure on the construction site. In addition, a spring is installed on the panel at a certain distance, helping to push out the column and secure it. In this article, a threaded connection of precast reinforced concrete columns is proposed, which can be used to connect elements of fully assembled buildings and structures. The contact-screw connection of precast reinforced concrete consists of an upper and lower column, both have a cylindrical steel external thread in the end section connected. The strength of the screw column connection is determined by ensuring the transmission of axial loads and torque in the joints, ensuring the destruction caused by cutting and thread confusion that may occur between the connected columns. By means of the necessary calculations for the screw connection of columns made of precast reinforced concrete the corresponding rigidity and strength were confirmed. The new connections will contribute to the development of construction, its energy efficiency and acceleration of the installation process. These are effective approaches to reducing effort, time, and labor and energy costs.
