Building Responsibility Level II. The building consists of four blocks: 3 one-story and two-story blocks in the central part of the building, designed according to a mixed (column-wall) structural system. The main supporting structures of one-story blocks are steel columns of box-section 180 × 8, I-section 30K1, 40K1 and roof trusses. Roof trusses (with a span of 15, 18 and 21 m) are made of steel from bent box sections. Rafter truss spacing is 6.0 m. Cover construction is non-purlin, with profiled flooring H114-750-1.0 resting on the upper belt of trusses, with purlins in the area of ​​snow bags. Ceilings of mezzanines (in the axes "I-T", "11-15" and "B-D", "10-13") - monolithic reinforced concrete slabs on fixed formwork from H75-750-0.9 corrugated board with a total thickness of 130 mm from B25 concrete , reinforcement class A500C for steel girders and beams. The main load-bearing structures of the two-story block are monolithic reinforced concrete columns with a section of 400 × 400 mm made of B25 concrete, brick walls 380 mm thick (M200 brick on M150 mortar). Overlapping and covering of a two-story block - a monolithic reinforced concrete slab 200 mm thick along cross beams 440, 500 mm high, from 500 to 2000 mm wide, made of B25 concrete. Exterior walls - three-layer "sandwich" - panels 150 mm thick with fastening to steel fachwerk elements and monolithic ceilings. The basement of the outer walls is solid brick 120 mm thick with an outer layer of insulation. The stairs of the two-story part of the building are monolithic reinforced concrete marches and platforms supported by load-bearing brick walls. Stairs on the mezzanine in the one-story part of the frame are metal. The spatial rigidity and overall stability of the building is ensured by the rigid connection of the columns with the foundations, the system of vertical connections and hard disks of floors and roofs. The project provides for the installation of a roof boiler house in a steel tie frame. The frame columns rest on the roof beams of the building. Covering - profiled flooring on steel girders and beams. Overlapping of the boiler room - a monolithic reinforced concrete slab on steel beams. The calculation of the load-bearing structures of the building was carried out using the SCAD 11.1 software package. The relative elevation of 0.00 corresponds to the absolute elevation of +4.00 m. The foundations are taken on a pile foundation. Piles - bored 350 mm using the "Fundex" technology, the working length of the piles is 11.2 m and 14.2 (14.4) m, the absolute mark of the pile tip is (minus) 8.2 m and (minus) 11.2 m. Concrete B25, W6, F100, class A500C reinforcement. Grillages - free-standing (under the frame racks) 800 mm thick and, partially, tape-shaped with a section of 600  600 mm, provided for brick load-bearing walls. Concrete B25, W6, F100, class A500C reinforcement. Pairing of piles and grillage is rigid. A 100mm thick concrete preparation is provided under the foundation. The basis of the foundations are sandy loamy plastic EGE-8 (IL = 0.40, e = 0.347, E = 80 kg/cm2), dusty sandy loam solid EGE-8a (IL = -1.0, e = 0.295, E = 180 kg/cm2), sands are coarse, dense, with gravelly lenses, less often medium-sized, saturated with water EGE-9 (e = 0.600, E = 350 kg/cm2). The calculated allowable load on a pile 12.0 m long is taken as 50 tf, on a pile 15.0 m long - 79 tf and confirmed by the test results. The floor slab of the first floor is made of monolithic reinforced concrete 250 mm thick (B25, W6, F100), separated from the pile grillages by an expansion joint. The calculated load on the floor slab is 0,6 tf/m2. The pressure on the base soil under the floor slab is 1,5 tf/m2. Under the floor slab, a crushed stone preparation of 200 mm along a sand cushion of 500 mm was designed. The maximum expected settlement of the floor slab is 2,5 cm. At the base of the pillow there are bulk and alluvial soils. The project provides for coating waterproofing of the outer surfaces of reinforced concrete elements in contact with the ground. The maximum expected settlement of the building is 1,5 cm. During the construction period, the project provides for geotechnical monitoring of the structures of the car park building. The project provides for the installation of a transformer substation (BKTP) from prefabricated prefabricated concrete elements.
