Estimate for the construction of a house from aerated concrete

The use of aerated concrete, which is classified as a "light" type of concrete, is the most economical material for building houses. Affordable price attracts developers. But before starting work, you need to calculate the approximate cost of the house. It should be borne in mind that the total amount of financial costs depends on a number of factors, since the house is not a box of concrete, but a full-fledged residential building, the construction of which involves the use of many building materials, special equipment, engineering networks.

How to make an estimate?

When making calculations, it is important to follow simple rules:

1. To begin with, you should study the necessary sources - norms, different calculation methods.
2. If you do not draw up a project in advance, you will not be able to calculate everything correctly. You will need the dimensions of the future structure and the materials that will be used.
3. It is important to know what building materials will be used for each element in the house. Otherwise, you will not be able to make an estimate.
4. Calculations can take more than one day. All results should be rechecked, because any inaccuracy can distort the data obtained, which will lead to incorrect consumption of building materials.
5. Before calculating, it is advisable to consult with a professional; the money spent on such a consultation will pay off with advice that will be useful to you in the future.

How to make a calculation?

Professionals recommend breaking the work into several stages - this will help to take into account all the data, despite the many numbers. It is important to move progressively from stage to stage. Thus, you will preserve the order, and if you make a mistake in the calculations, it will affect only a certain part of them, but not the total. Due to this, the estimate will be drawn up as accurately as possible.

Base

Without a doubt, the reliability of the structure depends on the strength of the foundation under the house. Therefore, errors can cause shrinkage, the formation of cracks, as a result of which it will be necessary to carry out heavy and expensive repair and restoration work. Estimating the foundation of a building involves taking into account the following factors:

1. First of all, you need to determine the weight. That is why the calculation of parameters, the exact consumption of building materials for a concrete base is made only when you know the other parameters. The mass of each element should be summed up so that you can calculate the weight load on the foundation before construction.
2. In addition, experienced builders take into account the peculiarities of the soil at the construction site: its type, composition, groundwater occurrence. You can ask about this in the special service. You can ask the builders of neighboring houses about the occurrence of sand, soil moisture.
3. When installing a base plate, you will have to remove the soil layer to create a depression. The slab will contain the side walls of the foundation, its parts laid under and above the ground. If the monolithic slab is located above the soil freezing depth, then under the base and 150 centimeters around the perimeter, the entire space should be additionally hydro and heat insulated to prevent deformation due to changes in the soil.
4. In addition, you need to remember about reinforcement. If the cost of the metal mesh is too high, fiberglass rods can be used to reinforce the aerated concrete. Despite the low cost, the quality of such reinforcement in aerated concrete will not be inferior to the characteristics of metal.

Box of gas blocks

Carrying out these calculations is considered the main stage of work, however, each stage of budgeting is extremely important. The calculation features look like this:

1. In construction, it is generally accepted that 40 centimeters is enough for the construction of an average strip of wall thickness. However, when carrying out work, it is necessary to take care of thermal insulation from mineral wool outside the building. Otherwise, the heat loss of the building from the gas blocks will affect the bills for its heating.
2. Determining the volume that is needed for construction is quite simple: you need to add the length of each wall, then multiply the result by their height, thickness. The resulting value is an indication of the total consumption in cubic meters.
3. It is advisable to use special glue, as this will help reduce the consumption of the composition during construction. In addition, the seams will have a minimum thickness, which will have a positive effect on the thermal insulation of the room. Such an adhesive solution is easy to use and easy to prepare.
4. Every three to four rows, the seams must be additionally reinforced with a metal mesh. Its thickness should be 3 millimeters. Sometimes reinforcement is made by reinforcement. To do this, cuts are made in the gas blocks, where the rods are laid, and then they are filled with a solution. The use of fiberglass reinforcement helps to save heat.
5. Window and door lintels are made from. It is necessary to install the formwork, and after installation, pour the mixture inside. It will also be necessary to make a belt of reinforcement in the upper part, the height of which should be no more than 30 cm. Due to this, it will be possible to correctly distribute the load of the roof.
