Abstract: The building is designed ten-storey with basement technical rooms under the entire area of the house, and with dimensions in plan 24.925 x 20.21 m. The height of the first basement - 2.40 m, all other typical floors is - 2.7 m. The house has a symmetrical planning and a simple geometric shape - rectangular. The structural scheme of the house is a three-dimensional frame and connection structure filled with 400 m thick gas blocks.The columns are rigidly connected to the monolithic floor slab and the foundation slab. To calculate the frame of a residential building, I collected the load on the frame structure in accordance with DBN B.1.2-2: 2006 "Loads and impacts". In the calculation and design section begins with the selection of reinforcement in a monolithic floor slab. The plate is made of concrete of the C20 / 25 class 200 mm thick. The next step is the manual calculation of the most loaded column of the basement with the selection of fittings. The cross section of the column is 800 by 250 . In the technological section, I developed a technological map for the installation of a monolithic floor slab and compiled a calendar schedule for the implementation of basic construction and installation work. It is estimated that the duration of construction of a residential building is 162 working days. In the economic section, I made a local estimate for the main construction and installation work. All calculations were made on the basis of prices and time norms for major construction works as of November 2020. I calculated the total cost of building an administrative building. The estimated cost of construction is UAH 300,93705. The purpose of research is to calculate the effectiveness of the design decision, taking into account the cost of construction and labor costs. I calculated the efficiency of two structural schemes of the house. After this calculation, a greater efficiency of using a complete monolithic frame was found. The efficiency was compared according to the following parameters: -total cost of construction; -total labor costs; Key words: technological map, column, gas block, reinforced concrete monolithic slab.
