Director General

We inform that the maximum possible dimensions in the axes of the designed production site on ul. Trolleybus 10 in the city of Gomel will be about 56x18 m (1008 m2). The area occupied by the existing production premises is about 40.8x12.5 m (510 m2).

For building construction in maximum dimensions it is necessary to perform:

- transfer of the water supply network ∅150 mm running parallel to the building with observance of the required distance from the foundations of the designed building;

- transfer of the water supply network ∅100 mm going between the existing building and TP115 falling under the building spot.

According to SNB 3.01.0402 "Urban planning. The layout and development of settlements "the distance from the foundations of buildings to the water supply networks should be at least 5 m. At the moment, the distance from the outline of the designed building to the water supply network ∅150 is about 4.38 m near the administrative part, and about 2.91 m near TP115. The length of the water pipeline ∅150 can be reduced to 60 m starting from the nearest well only when coordinated with the network owner. Please note that the distance to the well is taken from the outline of the building and is about 4.84 m. In reality, the distance from the foundations of the building protruding beyond the outline of the building will be less than the indicated within 1 m. Without coordination with the owner, the theoretical length of the network will be about 76 m.

When you decide to design the production area in the existing dimensions, we inform you that the distance to the water supply network of ∅100 mm coming between the existing building and TP115 is 3.21 m, which is less than 5 m and will also require the transfer of the network.

On the basis of the above, please provide a written response regarding the transfer of networks to determine the final dimensions of the designed building.

The diagram is attached .

With respect the director ,

Architectural part

Space Planning Solution

The existing special transport building is a rectangular structure in plan, consisting of several buildings built at different times.

The building is one-story, without a basement, with a volumetric and partially with a flat combined roof, and an unorganized external drainage.

The building consists of an administrative and household block, in which there are offices, bathrooms, ITP., An entry point, two car blocks-garages with a household, premises for rent, garage boxes for four cars, a warehouse. Car boxes have inspection pits.

The entrances to the building and to the garage boxes are carried out from the courtyard facade and from the courtyard territory of Tambur LLC at the entrance to the administrative block. The width of the corridors, taking into account the opening of the door blocks, is less than the standard one, according to paragraph 3.47 of SNB 2.02.0201.

Decoration of rooms on escape routes in administrative unit is made of combustible materials. which violates item 3.41 of SNB 2.02.0201.

The administrative block is separated from the garage block by a fire wall to the entire height.

Facades

The walls of the facades are made of ceramic brick and silicate stone. The walls are plastered and painted with facade acrylic paint. The walls of the late addition of silicate stone are not plastered.

The facades of the administrative block were repaired. The facades of the rest of the building have damage to the plaster layer and the paint layer.

Above the administrative block there is a new roof made of metal. The roof above the rest of the building is made of wavy asbestos cement sheets. Window blocks are wooden, glazing is partially absent. Window plums are broken. Window blocks in the administrative building are made new from PVC profile, new window drains and rolls are installed.

Interior decoration of rooms

The following decoration is made in the administrative block;

- cabins and corridor are glued with wallpaper for painting. The floors are ceramic, the ceilings are painted with acrylic paint.

Garage rooms are lined with ceramic tiles to a height of 1600mm. with acrylic paint, ceilings painted with acrylic paint, floors made of mosaic concrete.

In the rented room, a decorative panel made of PVC with oil color to the remaining height is made. Ceilings painted with acrylic paint, concrete floors.

Physical wear of interior trim 80%.

Window and door infills

Wooden window blocks with single glazing, painted. The paint layer has exfoliated, partially there is no glazing. The gate at the entrance to the boxes is metal, painted, in satisfactory condition.

Physical wear of wooden window blocks 80%

Physical wear of windows from PVC profile 10%

50% physical wear of metal gates

60% physical wear of door blocks

Conclusions and recommendations

When performing the reconstruction of this building for administrative trading, according to the customer's task, taking into account the current regulatory documents, it is necessary to perform the following;

-Reschedule ground floor spaces

-Perform the superstructure of the second floor, taking into account the load-bearing capacity of the structures.

-Swap window blocks.

- Repair the facades with subsequent painting.

- Perform decoration of the premises, according to the existing sanitary and fire regulations..

- Perform internal finishing of the administrative unit in accordance with SNB 2.02.0201.

Electrical part

Electrical devices of the building do not meet the current norms and rules, do not comply with the requirements of PUE and TKP454.04-149-2009 "Electrical systems of residential and public buildings."

Actual wear and tear is 80%.

It is necessary to carry out the design of power supply, electrical equipment and electrical lighting of the building on the basis of the customer's task, issued technical conditions, tasks of adjacent groups.

The project shall be executed in accordance with the current norms and regulations, the requirements of PUE and TKP454.04-149-2009 "Electrical equipment systems of residential and public buildings."

Complex output

On the basis of the above conclusions and recommendations based on the results of a technical survey of the building of special vehicles for multifunctional along Trolleybus Street, 10 in Gomel, by specialists of the ODO Zhilpromproekt, one can make a comprehensive conclusion that the wear and tear of a residential building (62.8%) and taking into account the requirements of the existing regulatory documents of fire and sanitary inspections and in accordance with TKP 45.1.042082010, Table 9.1, the building has category IV - inoperable (unsatisfactory) condition - urgent load limitation is necessary. Overhaul, reinforcement or replacement of elements or structures is required (specified by calculation). When redeveloping spaces and adding the second floor (as specified in the proposed redevelopment scheme), you need to:

strengthening existing foundations

partially strengthen, partially implement new external and internal walls;

in the floor level of the first floor, make a monolithic belt;

Implement the recommendations of the above sections.

This technical report is not a documentation for the performance of works. According to the given recommendations, design and estimate documentation should be developed.

All types of works on reinforcement and replacement of building structures shall be carried out by specialized organizations in accordance with the developed design solutions.
