IMPROVEMENT OF ORGANIZATIONAL AND TECHNOLOGICAL SOLUTIONS IN THE CONSTRUCTION OF A MULTI-STOREY UNDERGROUND PART OF THE BUILDING

Purpose. Substantiation of organizational and technological solutions due to innovative technical approaches for the construction of an underground multi-storey part of residential and public buildings aimed at increasing the efficiency of construction processes. Methodology. The work considers the construction of a building, at the level of the first floor, it is proposed to implement a system of interconnected rail tracks along which gantry cranes and special platforms will move. To lower machines, construction materials, tools to the design mark, when developing underground space, it is proposed to use gantry cranes. For the rapid relocation of cargo and machines from one grab to another, an additional system of rails is installed, along which special platforms are moved. Research of modern methods of underground construction, the use of the latest approaches, automated monitoring systems and digital modeling. Particular attention is paid to the selection of optimal technologies, taking into account geotechnical conditions. The development of effective design and technological solutions will improve the quality of construction work, reduce their terms and optimize costs. Findings. Optimization of organizational and technological solutions ensures cost reduction, reduction of construction time and increase of work safety. The use of modern technologies allows you to improve process control. Taking into account geotechnical conditions and the use of innovative approaches helps to increase the reliability of structures. Thus, the improvement of approaches to the construction of underground structures is an important direction in the development of the construction industry Construction of facilities is a process in which performing organizations, suppliers and consumers of material and technical resources, vehicles and other elements interact in a complex relationship. At the same time, the work is affected by many different, including random, factors. For their influence, it is proposed to take into account the joint influence of various factors, taking into account random factors of influence. Originality. The article discusses control of the movement of cranes and special platforms is carried out using remote controls. The above-ground part of the building is erected in the traditional way using a tower crane, for example, on a rail track. The use of the proposed technical solutions in the construction of buildings with multi-storey underground parts will allow improving the implementation of technological processes of the underground part of the building. The proposed technology will allow it to be used in all climatic regions of our country. Practical value. Based on the obtained relationships of qualitative and quantitative parameters, a model is developed and an algorithm for its calculation is built. In connection with the above, it is obvious that the development of such a model will allow a comprehensive assessment of the admissibility of combining construction processes.
