Fitness complex in Kronstad

General Instructions

1. The project is developed in accordance with the current norms, rules and standards.

2. The following regulatory documents are used in the development of the project:

- SNiP 2.04.0185 *. Internal water supply and sewerage of buildings.

3. Design Input

- Connection conditions of PMT "Vodokanal St. Petersburg"

- Architectural and construction task;

- Design assignment;

- Process assignment;

4. Technical data of the designed facility:

- Building volume - 34395 m3

- Fire resistance degree - II

- Number of floors - 5

- A fire class on NBP 16697 - C0

- List and number of consumers: see table of water flow rates and effluents.

5. Key Technical Solutions

- Internal domestic drinking water supply (B1 system);

- Internal fire water supply (B2 system);

- Hot water supply with circulation circuit (T3 and T4 systems);

- Domestic sewerage system (K1 system);

- Production sewage system (K3 system).

Water consumption for fire extinguishing of interior rooms - 2x3.7 l/s ;

The number of fire cranes is more than 12;

Water flow rate for external fire extinguishing - 25 l/s.

The duration of extinguishing the fire is 3 hours.

5.2. Hot water supply.

The design provides for the following hot water supply networks of the building:

- hot water supply according to closed scheme with circulation circuit along mains and risers - T3 and T4;

Hot water for household needs is prepared from cold in the ITP room in heat exchangers, the boundary of the internal networks of the WCS is the wall of an individual heat station.

Main networks and risers of hot and circulating water supply are laid from steel stainless pipes, local risers of hot water supply and connections to instruments are laid from polypropylene or metal-plastic pipes in thermal insulation to water-collecting devices.

Pipe laying - hidden (in set ceilings and shafts) and open in bathrooms. Shut-off valves (gate valves, ball valves) and water-saving water-discharge valves are installed on the systems. Shut-off valves are located in places convenient for maintenance. Disconnecting drain valves are installed on the risers. Automatic air valves are provided in the upper points of hot water risers. Compensation for thermal extensions of hot water pipelines is provided using U-shaped and L-shaped compensators.

5.3. Domestic sewerage.

Domestic effluents from bathrooms and showers are discharged to on-site networks at releases Øu100, Øu150 mm.

Pipe material:

- pipelines laid under the foundation slab, as well as sections of the domestic sewage network laid under the ceiling of the wardrobe from rooms 108, 109, 111, 112, are made of IPA Geberit pipes on welding.

- pipelines from ladders at inlets, as well as other gravity pipelines in the internal rooms, are laid out of Rospipe bell-shaped pressure-free pipes.

To ensure fire safety, risers from PP and PE must be sewn into boxes made of non-combustible materials. The design provides protection of all passages of sewage pipelines through monolithic ceilings or through walls of non-combustible ducts from fire propagation by means of fire cuffs of appropriate diameter.

Compensation for temperature extensions of polypropylene pipelines due to the difference in installation and operation temperatures is carried out due to bell joints sealed with rubber rings.

Pipe laying - hidden (in suspended ceilings and shafts, sewn in place).

At the outlets of the domestic sewage system from the devices located in the basement, electrified check valves are installed to protect against flooding in the event of a reverse overpressure.

Domestic wastewater flow rates are shown in the table of water and effluent flow rates.

5.4. Production sewage system.

Production effluents from process equipment of public catering enterprises, as well as emergency effluents from technical premises and melt effluents from pits at inlet groups, are discharged to the on-site network at outlets with diameter Øu100, Øu150 mm.

The project does not provide for cleaning of production effluents from the technological equipment of the fitness bar, since according to the technological section, catering enterprises operate on finished products without food preparation .
