In real estate with the definition of a groupThe capital of building objects has to be faced quite often. For example, you can not do without this procedure if you need a state registration of a building or a decision on demolition.
What does the term "building capital" mean?
Normative and technical literature does not accurately givethe formulated explanation of the signs of the capital of building objects. Nevertheless, this term refers to the strength, functionality and life of the building.
How to determine the building's capital group?
In order to assign a building to one or anothergroup of capital, a special expert commission is appointed. The examination process involves the evaluation of a number of indicators. The main ones are:
- Used materials for the construction of: foundation, walls, ceilings.
- Features of the design, providing physical and mechanical endurance of the structure.
- Degree of resistance to fires.
- The level of internal improvement, engineering communications.
Group buildings for civil use
Modern architectural solutions meandifferent capitality for buildings depending on their intended purpose. Thus, buildings intended for civil use (residential buildings) have less durability than industrial (public) real estate.
The period of accident-free operation is the key factor in determining the group of buildings and facilities capital, the table clearly shows this.
Capital group | Service life, years | Type of object, depending on used building materials |
the first | is not limited | Concrete, stone |
| the second | 120 | Ordinary |
the third | 120 | Lightweight stone |
fourth | 50 | Wooden mixed |
fifth | 30 | Wireframe |
sixth | 15 | Rumble |
I group of capital of residential buildings
The houses of the first class of capital meet the mosthigh quality standards. The maximum operating time is achieved thanks to a solid construction, mainly consisting of a monolithic foundation, walls and ceilings. The basic building material of the foundation is concrete, stone. The walls can be made of block, stone or brick masonry. Overlapping is made of reinforced concrete. The fire resistance of such objects is maximal. An example is multi-storey monolithic houses, of which predominantly any urban architecture.
II group of capital
Representatives of this class are not far behindthe first group for strength and durability. Unlike the first class, here the walls can also be large-panel. Such houses are gaining increasing popularity in the construction market, as they are built faster, and, most importantly, contractors are cheaper than monolithic ones.
III group of capital
For the construction of such houses is applieda mixed technology for the construction of walls with the use of lighter materials: bricks, cinder blocks, shell rock, etc. Such walls are easier to obtain than concrete or stone, but some percentage of physical and mechanical endurance is lost.
IV group of capital
In mixed constructions of houses of this groupUse such a building material as a tree. In the wooden version, walls (chopped, paved) can be made, overlappings, a lightweight belt foundation. Fire resistance and service life are significantly reduced compared to predecessors. By this type of low-rise houses are built, private cottages that do not heavily load the foundation.
V group
Skeleton-panel buildings belong to the woodenhouse-building. Wooden frame houses are mostly country cottages and cottages intended for seasonal use. Undoubted plus - low time and cost, minus - high fire risk and a relatively short period of operation.
VI group
Bright representatives - baths, sheds, garages and other temporary buildings and structures. They are designed for individual economic use.
Group capitalization of industrial and other buildings
To industrial and other buildingsseveral other technical requirements are presented, rather than to civilian objects, namely - the bar of the operational period increases. Below are the data that conditionally separate non-residential facilities into groups of buildings and constructions capital. The table reflects the main parameters of these tables, as well as the classification of buildings by capitality.
Capital group | Service life, years | Design Features |
1st group | 175 | Metal or reinforced concrete frame with stone filling |
2nd group | 150 | Walls of stone or large-block, reinforced concrete floors |
3rd group | 125 | Walls of stone or large blocks, wooden floors |
4th group | 100 | Wooden / brick pillars and columns |
5th group | 80 | Lightweight masonry walls |
6th group | 50 | The walls are chopped, paved or of logs |
7th group | 25 | Frame / panel structure |
8th group | 15 | Reed structures |
9th group | 10 | Temporary constructions (pavilions, tents, stalls) |
The service life of buildings by capital groupdifferent depending on the purpose of the object. So, for production facilities it varies from 15 to 175 years, while civil facilities are designed for use from 15 to 150 years. At the same time, the closer the group of the building's capital to the beginning of the classification series, the higher the requirements for its physico-mechanical endurance and fire resistance. It should also be noted that the level of capital is also affected by additional factors, such as interior finishing, engineering communications, as well as the technical equipment of the building.
