Capital and building capital groups

In the sphere of real estate, with the definition of a group of capitalization of construction projects, one has to face 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 give a clearly articulated explanation of the features 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 the building to one or another group 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 imply a different capital 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 a key factor in determining the group of buildings and facilities, the table clearly shows this.

I group of capital of residential buildings

The houses of the first class of capital meet the highest 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 brickwork. Overlapping is made of reinforced concrete. The fire resistance of such objects is maximum. An example is multi-storey monolithic houses, of which predominantly any urban architecture.

II group of capital

Representatives of this class are not far behind the first group in 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, a mixed technology is used for the erection 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 physico-mechanical endurance is lost.

IV group of capital

In mixed constructions of houses of this group, such building material as wood is used. In the wooden version, walls (chopped, paved) can be made, overlappings, a lightweight belt foundation. The fire resistance and service life are markedly reduced in comparison with predecessors. By this type of low-rise buildings are being built, private cottages that do not heavily load the foundation.

V group

Skeleton-panel buildings belong to the wooden house-building. Wooden frame houses are often country cottages and cottages intended for seasonal use. Undoubted plus - low time and cost, minus - high fire risk and relatively short life.

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 the buildings of industrial and other purposes, several 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.

The service life of buildings by capital group varies 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 capitalization is also affected by additional factors, such as interior finishing, engineering communications, as well as the technical equipment of the building.
