Abstract. After the development and approval of project documentation for the construction of a 25-storey residential complex (75 m high) in the city of Chelyabinsk, the Pioneer Engineering Company decided to replace the floors of monolithic bearing frame with precast-monolithic floors ARKOS. Working drawings of precast-monolithic floors were developed by Pioneer EC on the recommendations and with the participation of BESTengineering (Minsk, Belarus). After approval of working drawings and the start of construction, the customer made an additional decision to replace the cast-in-place frame of the two-level underground car parking and the two-story stylobate with the precast-monolithic frame ARKOS. To date, the complex with the completed replacements built and put into operation. The article presents a comparative analysis of actual material and estimated labor costs for working drawings of both types of bearing structures and possible options for their improvement, as well as the reasons that prompted the customer to replace the structures. As a result, material consumption, labor costs, and overall construction costs were significantly reduced. It is concluded that in order to reduce the cost of construction of residential and public buildings of mass use, it is advisable to complete their bearing structures with the maximum use of industrial prefabricated products.
Key words: monolithic structures, prefabricated-monolithic structures, frame, consumption of reinforced concrete, rebar consumption, labor expenditures. - REFERENCES
