Architectural and space-planning solutions.

The building of the general education school, which is subject to a comprehensive overhaul, is located in the depths of the quarter, has a U-shape in plan and is oriented with the main facade to the southwest, and the rear facade - to the northeast. The object is a non-residential 1-4 storey building with an unheated attic, technical underground (height 1.6-1.7 m) and basement areas. The volume of the building consists of a 4-storey part, which houses the main educational, technical and technological premises and two one-story extensions with two-story inserts designed perpendicular to the rear facade, one of which houses a gym (with utility rooms on the 1st floor of the insert and ventilation chamber on the 2nd floor of the insert), in the other - a dining room (with a food unit on the 1st floor of the insert, utility rooms of the catering unit and a ventilation chamber on the 2nd floor of the insert). The extensions are spaced to different ends of the building, forming the space of the courtyard. The courtyard of the school has a separate service entrance with a fence. As a result of the comprehensive overhaul, along with the overhaul of the GOU building, redevelopment and re-equipment of educational and industrial premises is envisaged. The capacity of the school building after a comprehensive overhaul is 484 students. In the basement areas, storerooms, technical rooms were designed: a water meter unit and an ITP room (the placement of these rooms and their area are taken according to the existing layout). The new floor-by-floor functional zoning for a comprehensive overhaul was decided as follows: on the ground floor, an entrance group of premises, a dining room with utility rooms (in a one-story extension), a gym with utility rooms (in a one-story extension), a conference room, a library, a medical center and a multifunctional office were designed for classes with MGN, sanitary units. On the second floor, it is planned to place a block of educational premises of an elementary school, administration and sanitary facilities, on the third and fourth floors - educational premises of the middle and senior level and sanitary facilities. Based on the technological requirements and fire safety requirements for the school premises, it is planned to reconstruct the existing and organize new porches, ramps and pits. It is planned to reorganize the entrance group from the side of the main entrance, due to the need to provide access for the disabled, the unsatisfactory state of the canopy structure and the heterogeneity of the geometric parameters of the steps within the march. The layout of the entrance porch was developed taking into account access for disabled people and people with limited mobility: a ramp is provided, the overall dimensions of the steps are 0,4x0,12m in accordance with the requirements of SNiP 35-01-2001 for external stairs, and a protective canopy is designed over the new porch. The project provides for the reconstruction of the porches with additional emergency exits from the corridors of the 1st floor in the axes 1-2 / B-C and 16-17 / B-C due to the lack of a platform between the door and the stairs. Also, at the exit in axes 16-17 / B-V, a ramp is arranged to ensure evacuation standards for the disabled. In connection with the requirements of the evacuation standards, an additional exit is being restored from the gym, located in the axes 4-4/1/E-Zh. Also, to ensure evacuation from the dining hall premises from the side of the courtyard facade, in place of the window opening in axes 12/1-13/G-D, an additional exit with a new porch was designed. These exits are equipped with an insulated door and an anti-panic handle. To meet the technological requirements for the catering unit of the dining room from the side of the courtyard facade (end of the extension), the existing doorway leading to the stairwell is laid in the axes 13-15 / Zh and a new doorway is arranged in the axes 15-17 / Zh with the reorganization of the entrance porch. This entrance is technological and is designed to load the dining room. The exits from the stairwells in the axes 6-7/D-B and 13-15/E-Zh are being reconstructed: the project provides for the installation of a fire cut between the flights of stairs and individual doorways to provide direct access to the outside from the basement areas. A pit is arranged in axes 14-16 / A to provide access to the premises of the water metering unit. The blocked window openings are being restored in the axes 16/A-B at the level of the first floor, the dimensions of the window openings in the sports hall, which were previously partially laid, are being restored, due to the technological need in the axes 17/E-Zh, a window opening is being laid to the installation depth window block. To preserve the arrangement of window openings on the facade, a blank window block is installed in the indicated place, pasted over from the inside with a dark opaque film. To organize air intake in the rooms of ventilation chambers, window blocks at the level of the second floor in axes 1/B-D and 17/B-D are replaced with louvered grilles painted in the color of the facade. A comprehensive overhaul provides for the dismantling of old and the installation of new partitions. Newly erected partitions: plasterboard partitions on a metal frame filled with mineral-cotton slabs, brick (as enclosing structures for basement rooms, wet categorized rooms), aerated concrete (shaft construction for laying ventilation networks). The interior decoration of the premises provides for: External doors - metal and metal insulated. Internal doors - wooden paneled: deaf and glazed, partially custom-made and in accordance with GOSTs, metal fireproof. Window blocks - two-chamber, metal-plastic with a tilt-and-turn mechanism and with a micro-ventilation function. Suspended metal cassette ceilings are provided in sanitary facilities, showers, locker rooms, KUI, in the premises of the catering unit, treatment room, doctor's office, in corridors, recreations, vestibules, wardrobes, educational and administrative premises - suspended ceilings made of Armstrong mineral fiber boards 600x600mm, in technical indoors, painting ceilings with water-based paints on a plastered surface. In classrooms, lecture halls, a library, a doctor's office, staff rooms, linoleum is provided as a floor covering by project documentation. In the lobby, cloakrooms, corridors, recreations, the dining room of the canteen, in the premises of the catering unit, ventilation chambers, pantries, archives, book storage, locker rooms and treatment rooms, porcelain stoneware flooring. In sanitary facilities, showers and KUI - ceramic tiles. In the gym and sports hall, the project documentation provides for the installation of a specialized sports floor. Laminate flooring has been designed in the administration premises. The walls of the showers, sanitary facilities, locker rooms, KUI, treatment rooms, the catering room and the wardrobe of the canteen personnel are finished with ceramic tiles to a height of 2,1 m. The surface of the walls of the classrooms is painted with water-based paints on a plastered surface. To improve the energy efficiency of the building, the project provides for the insulation of existing brick exterior walls by installing a hinged system of ventilated facades with surface cladding with porcelain stoneware. Rockwool-type mineral slab was designed as a heater for the outer walls. All fastening elements of the ventilated facade system are made of galvanized steel profile elements. Basement of the building - restoration of the waterproofing of the foundation and insulation of the basement with extruded polystyrene thick, which is then plastered with a cement-sand mortar along the grid and lined with porcelain stoneware. The 4-storey part of the building has a pitched roof, covered with galvanized roofing sheets, with an organized drain. In the 1-storey parts of the building (outbuildings) - the roof is cylindrical, with a roll coating, with an organized drain. The project documentation for the comprehensive overhaul of GOU No. 501 provides for measures to ensure access to the 1st floor for wheelchair users.
