    Abstract. Currently, the issues of construction of large industrial complexes with the same type of production lines and general utility facilities are not fully studied. From the condition of economic efficiency, a stage-by-stage commissioning of production is carried out with ongoing construction, i.e., the construction of queues. So, for example, for thermal power plants (TPP), it is typical to apply the phased construction with the separation of start-up facilities, while power capacity increases continuously. The studies devoted to optimization and selection of the most appropriate architectural and construction, organizational and technological solutions for TPP complexes do not always take into the account the technical feasibility of implementing the phased construction project under the current rules and regulations that are mandatory in accordance with the federal legislation of the Russian Federation. Therefore, in this paper, issues related to the mutual influence of technological equipment on the expandable (newly constructed) part of the building (for example, the main building of a thermal power plant), as well as as well as taking into account the influence of construction equipment on the operating conditions during the ongoing construction. As an example, a condensing, pulverized-coal-fired, steam power plant, with blocks of small unit power is selected. To calculate possible mutual influences, mathematical modeling was performed using the finite element method in software and computing complex, while the loads were taken into account as quasi-static. As a result of numerical modeling of the footing and foundations of the main building of the condensing power plant, the calculated values of the radii of influence zones of parts under operation and under construction on each other, as well as the values of the vertical movements of the foundations during the phased construction of the building are obtained. It is shown that with different degrees of fragmentation of the main building of the TPP in the construction phase, when implementing the flow construction scheme, it is not possible to avoid mutual influence from the construction of the building and the operation of the blocks in the previously built queue. In this regard, it is proposed to implement the main building of the TPP as separate buildings at a certain distance from each other as part of the equipment of the power units, equal to the estimated construction stage, which was determined on the basis of economic calculations.
    Key words: choosing order of construction, main buildings of TPP, architectural and construction solutions, organizational and technological features, mutual influence of construction and operational parts of building, foundations of dynamic machines, influence of construction machines on operated part of building.
