Architectural and space-planning solutions

 The designed building of the general education school of I, II and III stages of education with two swimming pools is designed for 550 students (22 classes). The building is of complex configuration in plan, with maximum dimensions in the extreme axes of 98,45x70,20 m, four-story, with a basement and a technical underground. The height of the building from the planning mark of the ground to the top of the parapet is 17,475 m. The mark of the finished floor of the first floor is taken as a relative mark of 0,000. In the basement at the level of -3,400, the following are designed: technical rooms for swimming pools, rooms for engineering equipment, utility rooms. The technical underground zone at the level of -2,200 is intended for laying engineering communications. The height of the basement floor from the floor level to the bottom of the ceiling is 3,00 m, the technical underground is 1,80 m. specialized workshops, a group of premises for a dining room and a kitchen block, a complex of pool premises with two-height halls of a large pool (with a bowl of 25x11 m) and a small pool (with a bowl of 10x6 m), a group of medical premises, office and utility rooms. On the second floor, primary school premises, a group of sports and recreational facilities with a two-height room of a large sports hall and a two-height room of a small sports hall, specialized classrooms, an auditorium, administrative and service and amenity premises were designed. The third and fourth floors provide for the placement of classrooms for primary and secondary schools, specialized classrooms, administrative and service premises. The height of the floors is 3,90 m. For vertical connection between the floors, 2 stairwells of the L1 type, two stairwells H2 and two elevators with a carrying capacity of 1000 and 630 kg without machine rooms are designed. The cover is flat, with an organized internal drain. Roofing - from rolled materials. In places where the roof adjoins walls with window openings, a non-combustible roof is provided (laying concrete paving slabs and embedded gravel). Access to the roof is provided through superstructures from the stairwells. Partitions: clay hollow brick, in rooms with a wet regime - clay solid brick. Filling window openings - metal-plastic window blocks filled with double-glazed windows, stained-glass structures. Interior decoration of premises - in accordance with their functional and technological purpose, using materials that have hygienic and fire certificates. Finishing of the facades of the building: basement - facing with artificial stone; above-ground floors - facing brick in three colors. Canopies have been designed over the entrances to the building. The project documentation provides for measures to ensure the accessibility of the building for people with limited mobility: at the entrance to the lobby of the 1st floor from the ground level, a ramp is provided; ramp covering - tiles that do not allow slipping when wet; the depth of the entrance vestibule is assumed to be at least 1,80 m, the width - at least 2,20 m; an elevator was designed with a cabin size of 2,10x1,10 m and a door width of 0,90 m; bathrooms with a universal cabin are designed.

 Structural and space-planning solutions

 The building is designed according to a frame structural scheme with external self-supporting walls and is divided into two blocks by a temperature-shrinkage joint. Building responsibility level - II. The transverse and longitudinal stability and rigidity of the building is ensured by the rigid pinching of the columns into the foundation, the presence of rigid monolithic floor disks, stiffening cores formed by the walls of the stairwells, and the presence of longitudinal and transverse walls serving as stiffening diaphragms. Columns - monolithic reinforced concrete, made of concrete B25, section of columns 400x400 mm, grid of columns 6,6x6,6 m. Walls of stairwells and stiffening diaphragms - monolithic reinforced concrete, made of concrete B25, 200 mm thick. The outer walls of the basement are three-layer: the inner bearing layer is made of monolithic reinforced concrete 500 mm thick, the insulation layer is 120 mm thick and the outer layer is made of monolithic reinforced concrete 140 mm thick; concrete B25; W6; F150, Ceilings and roofing - monolithic reinforced concrete beamless slabs 200 mm and 250 mm thick (above the basement) made of B25 concrete. The load-bearing structures of the roof above the pool rooms are steel roof trusses with a span of 18.0 m and 12.0 m and from bent closed profiles. Steel C345. Covering - profiled flooring on steel girders. Covering over the sports halls and over the assembly hall - prefabricated reinforced concrete prestressed multi-hollow slabs 500 mm thick, with a span of 12,0 m and 18,0 m along monolithic reinforced concrete beams. External walls - self-supporting, from a layer of porous ceramic stone 2.1NF brand M150 640 mm thick with an outer layer of facing brick F100 120 mm thick. The external walls in the pool area are self-supporting, made of a layer of solid brick M150 510 mm thick, a layer of insulation and facing bricks 120 mm thick. The project provides for the fastening of self-supporting walls to the supporting structures of the building. The pools are designed as monolithic reinforced concrete bowls made of B25 concrete; W6, based on monolithic reinforced concrete walls. Stairs - from monolithic reinforced concrete B25. Elevator shafts - from monolithic reinforced concrete B25 200 mm thick. The load-bearing structures were calculated using the Lira 9.6 software package. The foundations are taken on a pile basis. Piles - driven, composite, prefabricated reinforced concrete, section 35x35 cm, length 22 m, with an absolute mark of the pile tip - minus 20.00, from concrete B25; W6; F150. The connection between piles and grillage is rigid. The design load on the pile is assumed to be 72 tf. Grillage - in the form of a monolithic reinforced concrete slab with a thickness of 700 mm from concrete B25; W6; F150. Under the grillage slab, a concrete preparation 100 mm thick and a crushed stone pad 200 mm thick are provided. The relative mark of 0,000 corresponds to the absolute mark of 4.30. The base of the piles is silty plastic sandy loam EGE 10 (IL=0,18; e=0,314; E=10 kg/cm2) and semi-solid and soft plastic silt loam EGE 11 and EGE 12 (IL=0,11 (0,64), e = 0,441 (0,784), E = 130 (85) kg/cm2). The design load on the pile was adopted based on the results of static sounding.
