Building with construction volume of 4,500 m3/in St. Petersburg - ASG Complex Project

1. Brief description of the construction site

The site allocated for the construction of the building is located in the city of St. Petersburg and is free from development. The relief of the section is calm, the absolute elevations within the withdrawn section vary from 8.80 to 8.95.

The building is two-story, with a pitched roof. The size in the plan is 50.4 × 15 m. The premises are designed taking into account modern requirements, which was reflected in the layout and size of the premises. The structural diagram of the building is a monolithic reinforced concrete frame with load-bearing columns on the outer and inner sides of the building and non-bearing internal gypsum concrete partitions. Rigidity provides counting of closed monolithic walls of staircases and end walls on side facades. Skate top elevation + 11.340 m. Facade facing - stained glass windows of three layers of tinted glass. Ventilated façade made of ceramic granite with insulation of 100 mm of basalt wool is made on walls.

The foundation of the building is made of monolithic reinforced concrete, in the base of the foundation cement sand preparation with waterproofing carpet along it. Load of bearing walls is taken up and foundation cushions are transmitted to soil.

Intermediate floors are made monolithic reinforced concrete 100 mm thick. In toilets, it is necessary to ensure waterproofing of the floors by applying several layers of watercolor along the mastic.

Partitions between rooms are made of gypsum concrete blocks (400x400x100; 400х400х120). On the ground floor between the corridor and the trading rooms, the partition and the door are made of double-glazed windows. Glazing windows are also used for stained glass windows and entrance doors of the first floor.

Staircase made of reinforced concrete marches, stage platforms made of prefabricated reinforced concrete plates of factory manufacture, external steel stairs with stone slabs.

The roof is designed gable. Soft tile is used as roofing material. Wooden rafters with runs are located so that people can move in the attic.

The building is located in a close proximity to the busy streets of Vyborg and Mira, which makes its adjustments to the construction plan and construction technology.

In the adjacent area, a parking lot for administration employees, asphalt paths around the perimeter of the building and a small recreation area in front of the main entrance are designed. The building is fenced with a metal wrought iron grille along the entire perimeter.

2. Space planning solutions

You can divide the building spaces into working, maintenance, and auxiliary spaces. Workers include office rooms. Service rooms include lobby rooms, toilets. Auxiliary rooms include technical rooms of the basement, vestibules, corridors, rooms designed to accommodate engineering equipment of the building, storage rooms.

In the basement there are warehouses for storing goods. The entrance to the warehouses is from the western facade. Entrance to the corridor is possible from the main staircase, as well as from the street side staircase. Ceiling height in the basement is 2.0 m.

On the ground floor there is a central entrance. A central corridor passes through the entire building along the longitudinal axis. The corridor connects four office halls, a hall, a toilet, a foyer, a main staircase and a spare exit. The ceiling height on the ground floor is 3.0 m.

On the second floor there are office rooms. As on the ground floor, the central corridor connects the reception rooms and offices. There is an extensive conference room and toilet.

The third floor is a half-hearted room.

3. Main Plot Plan Solutions

The project provides for the organization of the main entrance to the office from ul. Vyborg. A spare exit is provided on the west side of the building. Taxation of trees was not carried out due to the lack of green spaces. For garbage collection, the customer enters into an agreement with the housing and communal services for garbage collection from an additional garbage collection container located on the container site of the allotted territory.

4. Improvement of the territory

The project provides for a paving area with paving tiles

(paving stone). The plan of organization of the topography of the site is made taking into account the natural topography, drainage of surface waters and permissible slopes for traffic and pedestrians. The territory is landscaped. Currently, the issues of discharging stormwater into the storm sewer st. Mira, there is outdoor lighting .

5. Utilities

The construction site of the administrative-office complex is located in the quarter of the existing development, which has engineering networks and structures, so the water supply is carried out from the water supply network of the city of St. Petersburg. The building has designed a system of cold domestic and drinking water supply to provide for domestic and drinking needs.

The water supply of the building consists of the following main elements: water metering unit, distribution line, risers and supplies to the instruments, water intake and control valves, fire protection system.

The input, in turn, consists of the following elements:

- underground pipeline to water metering unit;

- water metering unit with connection of underground water supply line inlet located in the basement of the building with location of disconnecting gate valve in it;

Internal cold water supply networks are accepted from steel galvanized pipes (as per GOST 3262). Isolation valves are installed in the base of risers, on branches.

5.1. Sewerage

In the building, household sewerage system is designed, which serves to drain household and faecal waters.

Internal and yard sewage pipelines are designed by gravity.

Internal sewage networks are accepted from cast iron pipes 50 and 100 mm.

The internal sewerage scheme includes:

- branch pipes connecting sanitary devices with risers;

- risers passing through all floors of the house;

- discharges through which waste water from the risers is supplied via a discharge pipe to the city sewerage network.

For rainwater runoff, galvanized iron drainage pipes are provided at the corners of the building. A gutter is provided around the building on the pavement, along which water flows into an underground channel leading to the roadway to the sewer hatch.

5.2. Heating

Heating, as well as hot water centralized. Heat supply of the building is provided from external heat networks with coolant parameters: Tpr = 95 С, Tobr = 70 С.

Heat supply networks are designed from steel pipes according to GOST 1070476, hot water supply networks from steel plumbing galvanized pipes according to GOST 326275. Hot water supply, centralized with circulation at the input. Hot and circulation inlets are laid together with heating pipes in the heating network channel. Corrosion protection of pipelines is adopted by four layers of organosilicate paint type OS-5103 with natural drying hardener. Two independent heating system risers were designed. Each riser of the heating system is accepted as double-tube with associated movement of the coolant. Pipeline insulation of heating system consists of products of mineral wool s = 30 mm with subsequent coating of ruberoid and glass fabric. Pipeline slope is accepted i = 0.003. Convectors M140AO * (lightweight) are used as heating devices for the installation.

Double control valves are installed on the inputs to the heating devices, air removal from the heating system is carried out through air outlet valves of convectors installed in the upper plugs of the heating device. Uninsulated places of pipelines and heating units are painted with oil paint (on site or in factory conditions) in 2 times. Gaskets between sections of convectors are made of 2 mm thick paronite as per GOST 4817593.

5.3. Ventilation

The building has designed a channel system of natural ventilation, its advantage lies in the simplicity of the device, economic operation and noiselessness. It is carried out naturally through brick canals in the internal and external walls of the building.

Air exchange is designed in the volume of 50 m3/h per 1 m2 of area.

5.4. Power supply

Power supply is carried out from city substation with powering on two sections two cables - the main and the AAB 2L1000 spare brand, section 3х50х1х25. The electric panel is located in the basement. Low-frequency voltage 380/220 V.

Cables lie in the ground in a reinforced concrete trench at a depth of 0.7 meters from the level (planning mark) of the ground surface of this area. When crossing each other, other communication lines and street passes, cables are laid in asbestos cement pipes with a diameter of 100 mm.
