Architectural and space-planning solutions

The hotel building is designed as a three-story building with a basement and a technical floor (third floor) and consists of three blocks: a hotel block, a health complex and an integrated catering facility. The hotel block is designed on the 1st and 2nd floors of the building and includes: a reception and vestibule group, rooms for living, service and amenity premises for staff, lounges for guests and five massage rooms with hot tubs. The wellness complex, designed both to serve residents and visitors from the street, is designed on the first and basement floors of the hotel building and includes the following facilities: a health pool, dressing rooms (men's and women's), showers, bathrooms, Turkish steam rooms, recreation areas, utility rooms. In the integrated public catering enterprise, the project provides for the unification of several types of public catering enterprises: bar No. 1 for 28 seats (in the basement), bar No. 2 for 42 seats, a cafe for 28 seats located on the ground floor of the building and loading products in the axes 1-2, V-B, located in the basement. In the basement floor, the project also provides for the placement of administrative premises, a luggage room (for guests' belongings), a foyer (multifunctional hall) with a bar, sanitary facilities, showers, a dressing room for outerwear and dressing rooms for storing work and home clothes and a dining room (for hotel staff). ). On the third (technical) floor, located above a part of the building, it is planned to place technical rooms, ventilation chambers and a roof gas boiler room. In the hotel building, 2 evacuation stairwells of the L-1 type, 1 lift for the MGN (at the entrance area) Q = 180 kg, 1 cargo lift (for the loading area) Q = 600 kg, 2 microlifts (for delivering semi-finished products from the loading area to the cafe and for waste disposal) Q = 100 kg and 2 passenger lifts Q = 800 kg. In the exterior decoration of the walls of the hotel building, the ALUKOBOND system was adopted by the project. The roof is flat (partially gable in the central part of the building) with an internal drain with a roll coating, The project provides for measures to ensure the life of people with limited mobility.

Structural and space-planning solutions

Building responsibility level - II. The building was designed in monolithic reinforced concrete structures according to a frame structural scheme with floor hard disks. The spatial rigidity and stability of the building is ensured by rigid pinching of the columns in the foundations and the joint work of all columns and hard disks of the floor and roof. Scheme of the frame of the main part of the building - with cross frames, consisting of columns and floor beams rigidly connected to them, located in mutually perpendicular directions. The scheme of the frame of the central part (pool) - with transverse frames, consisting of columns and rafters. Spatial rigidity and stability is ensured by the hard disk of the pool cover and the floor beams of the main part of the building, rigidly connected to the columns along the contour of the three-height pool. The column spacing - from 4,3 m to 12,0 m - was adopted based on planning decisions, the section of the columns is 600 x 400, 44 x 400, 300 x 400 mm, class B30 concrete. Walls and pilasters of the basement - 400 mm thick, made of hydrotechnical concrete class B30, W8. Ceilings - beam monolithic slabs with a thickness of 180 mm, based along the contour on beams with a section of 400 x 650 ÷ 1650 mm (H), class B25 concrete. The pool cover is made of prefabricated prestressed reinforced concrete SI crossbars and ribbed TT - floor slabs 500 mm high. The maximum span of the beams is 23,8 m; slabs - 7,65 m. Prefabricated reinforced concrete products - individual production. The support of the roof beams on the columns is hinged. The rigidity of the precast concrete pavement disk is ensured by welding the embedded parts of TT-slabs and crossbars, the device of a reinforced reinforced concrete screed, performed simultaneously with the sealing of the joints between the TT-floor slabs, and the diaphragm walls located between the rafters. Stairs - monolithic reinforced concrete. External walls - non-bearing three-layer, based on ceilings of aerated concrete blocks of class B 2, F15 with mineral wool insulation and a ventilated facade. The external walls of the pool room are multi-layered, made of ceramic stone, effective insulation and facing tiles, with a vapor barrier under the tiles. Connection of layers of multilayer walls and fastening to load-bearing structures is carried out by flexible connections. On the roof of the building, a container-type roof boiler house is installed, made in light steel structures. The container is installed on a paving slab covering on a cement-sand screed, arranged on a monolithic reinforced concrete slab. The static calculation of the building, taking into account joint work with the base, was performed using the SCAD computer system. A relative elevation of 0.000 corresponds to an absolute elevation 7.350 m. Engineering and geological surveys at the construction site have been completed. The foundations are a monolithic reinforced concrete slab 800 mm thick made of hydrotechnical concrete of class B30, W8, under the slab there is a concrete preparation 100 mm thick made of concrete of class B15 for crushed stone preparation (200 mm) and a soil cushion. At the base of the foundations - sands are fine brown, saturated with water, sandy sandy loams are solid, loams are light silty solid and semi-solid. The average pressure on the base is 0,5 - 1,5 kg / cm2, the expected draft is 6-7 cm. The groundwater level is located at a depth of 1,3 ÷ 1,7 m from the earth's surface. The maximum position of the groundwater level is near the surface of the earth. Groundwater is non-aggressive towards concrete of normal permeability. The project provides for waterproofing of the foundation slab and vertical walls of the buried part. The normative depth of freezing of fine sands is 1,55 m, bulk soils are 1,7 m. To prevent freezing, it is planned to insulate the walls of the basement floor with effective insulation and build foundations below the depth of soil freezing. The impact of the construction on the surrounding development is not expected.
