Architectural and space-planning solutions:

The designed business center building is 9-13 storey, with a basement, has a complex volumetric composition and a complex curvilinear outline in plan, the main dimensions in the axes are 34,20 x 70,00 m. The maximum height in the 13-storey part is 48,750 m from the planning mark of the earth - does not go beyond the requirements of the height regulation of the PZZ (55 m). The building, in addition to the office part, includes commercial premises, a cafe for 50 seats, a built-in parking lot for 85 cars, as well as technical and utility rooms. The office part is separated from other functional areas in order to provide more comfortable placement of administrative premises and ensure greater accessibility of public premises for citizens. The office part consists of blocks of various sizes, which group office and related premises located on floors 3-13. The first and second floors are reserved for the shopping area. Part of the 2nd floor is occupied by a cafe, part of the production premises of which are designed on the 1st floor. The 1st floor also houses the lobby group of premises, the administration of the business center, a block of technical and utility rooms, bathrooms and booths of trade enterprises and cafes. In the basement, a built-in heated underground car park with a curvilinear ramp is designed for cars of the office center employees and visitors to the complex. The basement also houses the technical and utility rooms necessary for the operation of the business center. Ventilation chambers, machine room of elevators and head station of television are designed at the level of the roof of the building. The height of the floors of the office part is 3,3 m, the height of the floors of the shopping area and the cafe is 3,9 m. The height of the basement floor is 2,95 m. All functional areas: office part, shopping area, cafe and parking lot - have isolated entrances and emergency exits. The office part is served by two staircases designed in a dispersed manner. For communication between the 1st and 2nd floors of public premises, an open staircase is provided, evacuation from the 2nd floor - along the 2nd evacuation stairs. All stairs have direct access to the outside. For vertical communication between floors, 3 main passenger-and-freight elevators with a carrying capacity of 1000 kg are designed. For lifting to the 2nd floor of public premises, 2 freight elevators with a carrying capacity of 630 and 400 kg, as well as a passenger elevator with a carrying capacity of 1000 kg are provided. Finishing of the facades of the building - porcelain stoneware, stained-glass windows. The plinth is natural stone. Interior decoration - according to a separate design project. According to the design assignment, the project documentation ensures the accessibility of the building for people with limited mobility in accordance with SNiP 35-01-2001 at the level of the first and second floors. Parking spaces for the disabled are provided in the open car park.

Structural and space-planning solutions:

The building is thirteen-story, divided by deformation-sedimentary seams into 2 blocks. The building was designed according to a frame, beamless structural scheme. External walls - non-bearing, made of monolithic lightweight concrete of D1600 density grade, 160 mm thick, insulated with mineral wool boards, lined with a facade system. The layers are connected by stainless steel anchors. Monolithic lightweight concrete walls are attached to the supporting structures of the ceilings with reinforcing bars d12 mm in increments of 300 mm. Internal walls - monolithic reinforced concrete 200 mm thick. Basement walls - external monolithic 200 mm thick, internal monolithic - 200 mm thick. Concrete of monolithic walls B25, W8, F150. Ceilings - monolithic slabs 200 mm thick. Concrete B25. Columns - monolithic reinforced concrete section 400x400 ... 500x500, diameter 400 ... 600 mm from concrete B30, B40, class A500 reinforcement. The main step of the columns is 7,8 x 7,8 m. The covering is a monolithic reinforced concrete slab 200 mm thick. Concrete B25. The spatial rigidity and stability of the building is ensured by the joint work of the longitudinal and transverse load-bearing walls of the staircases, the rigidity of the supporting nodes of the columns and hard disks of the floors. The calculation of load-bearing structures was carried out on a computer using the SCAD11.3 program. Stairs - monolithic reinforced concrete. The foundations are piled, the piles are reinforced concrete bored, with a diameter of 460/560 mm, according to the “Fundex” technology, 19 m long. Concrete B25, W6, F100. The design load on the pile is 125 tons. Grillage - in the form of a monolithic ribbed reinforced concrete slab 250 mm thick with ribs 800 mm thick, concrete class B25, W8, F150. Pairing of piles and grillage is rigid. A 100mm thick concrete preparation is provided under the foundation. The calculation of the foundation was carried out on a computer using the SCAD11.3 program, taking into account the work of ground structures. The relative elevation of 0.000 corresponds to the absolute elevation of +8.050 m. In accordance with the report on engineering and geological surveys, hard clays IL = -0,33, E = 22 MPa serve as the basis of the foundation. The allowable design load on the pile was adopted based on the results of static sounding. Before mass pile driving, the bearing capacity of the piles will be checked by static tests. After driving the piles, control tests of the piles will be carried out. In order to protect the concrete of underground structures, the water resistance grade of concrete is W6, W8. The working draft provides for waterproofing the basement by coating the outer surfaces of the walls of the basement floor with Intertol composition, installing waterstops in expansion joints. The expected average draft of the building is 51 mm. The surrounding buildings are located at a distance greater than the depth of the compressible thickness. The impact of the construction on the surrounding development is not expected. In connection with the approach of the surrounding buildings closer than 30 meters, monitoring of the sediment behind the existing buildings is envisaged.
