Calculation costing online. The cost of building a house: features of the calculation of building materials - what can be calculated on the online calculator

Every person who at least once in his life has encountered the construction of a private dwelling and other buildings knows how important it is to accurately and correctly prepare a project, calculate materials for building a house, etc. In this case, a number of features, the specifics of the building, the climate, and other nuances should be taken into account. After all, sometimes, even the price of a minor mistake in the construction of a building can be too high.

However, do not despair, even if you do not know all the building nuances, do not remember or do not know how to use algebraic formulas. Our site contains online calculators for calculating the construction of a house, the volume of liquid, the area of \u200b\u200bthe roof, materials for the foundation, etc. All you need is to take a tape measure and measure a few basic parameters, on the basis of which our program will perform a full calculation.

Let's take a quick look at how to use the presented online calculators.

Important! Despite all the precise calculations and calculations, it must be taken into account that 5-7% of all building materials will go to waste. That is why when purchasing materials, consider the stock.

Each of our calculators for the consumption of building materials and the cost of work already includes all the necessary algebraic and geometric formulas. You just have to measure the main parameters correctly and enter them in the appropriate cells.

We hope that our service will help everyone who plans to build a house or other buildings, both with their own hands and with the help of qualified specialists.

Today, the construction of houses from foam concrete is gaining momentum. And this is not surprising, because this material has such parameters that cannot but attract buyers. There are several opinions on how to correctly calculate the cost of building a house from foam blocks.

We will focus on this issue in this article.

Why foam block

First of all, we recall: do not confuse foam concrete with aerated concrete. In one of the articles on our website, the fundamental differences between these two materials are discussed in detail. It should be noted that the price of foam concrete is more favorable.

What he really is

The foam block is a small "bar" made by mixing concrete mix with special foaming components. It is the foam that forms cavities in concrete, which reduce its weight and increase heat-insulating parameters.

Its standard size is 200*300*600 mm. For clarity, look at the photo below, and imagine how much time you can save on laying foam blocks.

Houses made of this material cost significantly less than houses of the same size made of brick or, for example, timber. And if you are not too lazy and build everything with your own hands, then the savings will exceed even the wildest expectations.

Having an attractive price, foam block houses or cottages are in no way inferior to stone or wooden ones in their parameters. An attractive feature of the material can also be called its environmental friendliness.

Material advantages

In the production, additives that negatively affect human health are not used, which makes it possible to build children's or health complexes from it. With such a construction, considerable attention is paid to sound insulation - and foam concrete knows no equal in it.
The very structure of the material is favorable for further processing. With the help of simple tools, you can give the block any desired shape.
The porous structure does not interfere with gas exchange and the house "breathes" no worse than a wooden one.
From the previous paragraph, it logically follows that such a house is not characterized by excessive humidity and dampness.. With foam concrete, you will forget about mold and drips.
Not only the size, but also the laying principle will help save time and mortar. After all, the gap between the blocks should not exceed 3 mm.
Both exterior and interior decoration will also not cause you any extra trouble, because the plaster layer does not have to be thick at all.
Foam concrete has excellent fire resistance. At high temperatures, the material does not crumble or crack, it protects the fittings from heating. In the event of force majeure, such a house will not let you down.

Cons of the material

There are few of them, but they are still present:

Light weight with a large volume, of course, leads to a loss of strength. For this reason, the foam block has not received and will not be widely used in multi-storey construction. Although, after all, you are building a private house, and this is unlikely to be a problem, because cottages are rarely higher than 3 floors.
The need to monitor the correct laying. If the solution layer exceeds 3-4 mm, then you risk losing both heat and sound insulating properties.

Let's get to the main question.

So, our main task is to calculate the cost of building a house from foam blocks. It cannot be done separately from the clarification of the stages of construction. After all, only by disassembling the whole process in parts, you can take into account every detail.

Count

The calculation of the foam block for building a house should be based on the area of \u200b\u200bthe walls. Foam blocks are sold in cubic meters and to find out the quantity you need, simply multiply the thickness of the block by the area of \u200b\u200bthe walls.

The full calculation of the cost of building a house from foam blocks is as follows:

we will stipulate right away that our sample has a width of 8 m, a length of 10 m and a height of 3 m. Capital and external walls are taken into account.
the cost of the roof, foundation and other works can be calculated using separate calculators on our website.
so, we calculate the perimeter of the building: 10 * 2 + 7.4 * 2 \u003d 34.8 m (round up to 35). A reasonable question arises: how much is 7.4 meters, and not 8? The answer is simple: you folded 2 walls of 10 meters each, and from eight you need to subtract the width of the block, that is, 30 cm.
now we find out the area of \u200b\u200bthe walls: 35 * 3 \u003d 105 sq.m. Everything is clear here: the perimeter multiplied by the height.
From the resulting area subtract the area of windows and doors. This is purely individual for each project, so for convenience, let's assume that they occupy 10 sq.m. Remains 95 sq.m.
We find out the area of the foam block: 0.6 * 0.2 \u003d 0.12 sq.m. It turns out that for 1 sq.m. accounts for 1 / 0.12 \u003d 8.3 foam blocks.
So, we complete the calculation: 95 * 8.3 = 788.5 blocks are needed for the outer walls.
It would seem that the calculation of materials for building a house from foam blocks is over, but no! We did not take into account the main wall.
Its length in our sample will be 9.4 meters. We multiply by the height - we get an area of \u200b\u200b28.2 sq.m. Again, let's say that windows and doors occupy 5 square meters. We get 23.2 sq.m. 23.2*8.3= 192.5 blocks.
We add up the numbers obtained: 788.5 + 192.5 = 981 blocks are needed for such a building.

So, the calculation of building a house from foam blocks showed that we need 981 blocks. There are 27.7 blocks in one cubic meter. With a simple calculation, we find out that we need 35 cubic meters.

The cost of 1 cubic meter is about 3000 rubles. As you can see, a house of a given size will cost a very modest amount. Of course, this is just the frame of the building, but you must admit that the same brick would cost 2-3 times more.

It is worth noting that this instruction is approximate and an accurate calculation is possible only with a thorough knowledge of the project.

Construction progress

the first step is to build a foundation for a house of foam blocks. Since the foam block is lightweight, there is no need to spend money on expensive monolithic foundation. An excellent replacement for it can serve as a tape, which spends much less rubble, sand, concrete, and even takes smaller diameter reinforcement.

after the base gains the desired strength, it is time for laying. They start it by laying roofing material between the base and the first row as a waterproofing.
corner blocks are laid first. Moreover, special attention is paid to the corner, which, according to the plan, will become the highest. The corner is leveled and proceed to the next.
then a cord is pulled over the corners and the space between them is filled. If a whole block does not fit in one of the rows, then the excess part is cut off from it and the resulting piece is placed in the gap.
each next row is installed according to the same principle: from the corners. Verticals and horizontals are checked by level and cord.

Advice!
Remove possible irregularities immediately with a planer.

To prevent the walls from cracking during shrinkage, the masonry must be reinforced. Reinforcement with a diameter of 8 mm is laid in pre-cut grooves measuring 4 by 4 cm, which, after laying, are filled with glue or mortar.

Electrical wiring is also laid in strobes according to the same principle, however, the laying scheme depends on the specific project.

Particular attention is paid to door and window openings. All cut grooves are lined with a metal corner flush.

Another little tip: to cut blocks, you need to use a special hacksaw for foam concrete with large teeth.
With proper cutting, you will avoid crumbling of the material.

For interior decoration an excellent option would be drywall, board and textured plaster. From the outside, it’s even easier - use siding or finishing bricks.

Summing up

As you can see, the calculation of building a house from foam blocks cannot be called a very complicated process. But this in no way detracts from its importance in planning work.

To delve even more into the process of erecting a foam block building, pay attention to the video in this article. Until we meet again on the pages of our site.

Calculation of the cost of materials for the construction of an insulated house contour (house box)

Before you start looking for the house project you need to build, we recommend that you use our calculator for calculating the cost of materials for building a house box. After spending quite a bit of time, you will have an idea of the order of the amounts that you will need to spend on the purchase of materials for building a house. We want to warn you right away that our calculation is approximate, but at the same time, as a rule, the discrepancy between the result obtained and the amount indicated in the construction estimate, in most cases, has a difference of no more than 10-15%. The parameters used by our calculator are always up-to-date and are updated once every three months.
Attention: The calculator takes 3-5 seconds to load. Wait.

* Required fields: length and width of the house (in meters).

IMPORTANT: The calculator only calculates materials for construction. To get the full cost of construction, that is, materials + work, we recommend that you apply for a free calculation to our partner construction companies. But, first, you need to choose a house project in our catalog. You can order such a calculation by clicking on the link below:

Construction calculator - tell your friends!!!

If you are looking for project documentation for construction or competent builders capable of building a solid and solid house, we recommend that you first obtain high-quality and professional advice from specialists from the following companies.

Select total area

The total area according to SNiP is the sum of the areas of all floors of the house, calculated according to the internal contour of the external walls (including stairs, internal walls and partitions).

The areas of balconies, loggias, porches, terraces and verandas are considered with decreasing coefficients from 0.3 to 1. The attic area is considered to be up to vertical walls 1.5 m high, with a roof slope of 30 degrees. Below 1.5 to 0.9 m with a factor of 0.7. Below 0.9 m is considered a dead zone.

If you experience difficulty in calculating the total area, please contact our specialists. There is also an imperial way - add to the "total area" indicated in standard project 20%. As practice shows for two-story house the error will be 3-5 m2.

Basic equipment "box at home"

Foundation

Choose foundation

The foundation is the foundation of the house. His choice primarily depends not on personal preferences, but on the geological structure of the soil on the construction site and the chosen design solutions for the future home.

The foundations we use with their design features provide bearing capacity with any technology of walls, ceilings, roofs and facades we offer. However, soil weakness or high level ground water may require type adjustment or design features foundation.

Select walls

1. Aerated concrete blocks
Aerated concrete, gas silicate blocks (not to be confused with foam concrete) are manufactured at the factory with a set of strength in autoclave ovens. The blocks have an ideal geometry, which allows them to be placed on thin-seam glue with no cold bridges. Aerated concrete blocks with a density of 400 and 500 kg / m3 allow you to build houses up to 3 full floors without the use of reinforcing monolithic frames. The block thickness of 400 mm is sufficient for construction in the Moscow region using modern heat engineering.
2. Large format ceramic blocks
Ceramic large-format blocks (warm ceramics) have replaced piece solid bricks. Sawdust is added to the clay and when burned, they burn out leaving small closed pores, due to which the blocks have very good performance in terms of heat engineering. To preserve heat in the masonry, the blocks are laid on a special heat-insulating mortar with perlite, and thanks to the tongue-and-groove system, they can do without filling the vertical joints with mortar. Thickness of 440 mm is enough for the Moscow region.
3. Monolithic (fixed formwork Plastbau)
Swiss technology Plastbau is a technology monolithic construction with the use of fixed formwork made of expanded polystyrene. Wall panels are completely manufactured in the factory, including the reinforcing cage, and are delivered to the facility in cuts for a specific house project. Factory production allows you to get the ideal geometry of wall panels, which you only need to mount and add concrete. The outer layer of insulation is 100 mm, and the inner 50 mm. Such insulation is not only sufficient, but also exceeds the requirements for the Moscow region, i.e. this is an energy efficient technology.
4. Monolithic (fixed formwork Velox)
The Austrian Velox technology is a monolithic construction technology using fixed formwork made of chip-cement slabs. The slabs are manufactured in the factory in standard sizes of 500x2000x35 mm, the outer layer uses 150 mm thick expanded polystyrene insulation, which exceeds modern requirements for heat engineering for the Moscow region. The slabs are easily mounted on site, additionally reinforced and filled with concrete. In the built box of the house, the effect is felt wooden house thanks to the smell of wood.
5. Monolithic (fixed formwork Durisol)
The Austrian Durisol technology is a monolithic construction technology using fixed formwork made of chip-cement blocks. The blocks are manufactured at the factory, the outer blocks are insulated with expanded polystyrene 150 mm thick, which exceeds the modern requirements for heat engineering for the Moscow region. The blocks are easily mounted on site, additionally reinforced and filled with concrete. In the built box of the house, the effect of a wooden house is felt, thanks to the smell of wood.
6. Expanded clay concrete blocks
Expanded clay multi-slot blocks around the perimeter of all load-bearing walls of the house. Non-bearing partitions made of gypsum tongue-and-groove boards.

Walls are what, as a rule, everyone calls a house built from. "What is your house made of? Brick, and yours? And mine is made of aerated concrete."

Of course, that the house consists not only of walls, but primarily the customer is repelled from their choice.

All wall technologies used by us comply with the current standards for heat engineering in accordance with SNiP for the Moscow region. There are also technologies for increased energy saving, mainly with the use of fixed formwork.

And of course, each technology provides sufficient bearing capacity for building a house up to 3 floors inclusive.

Overlappings

Select Floors

Overlappings, the design of which was developed by our company, allows you to cover spans up to 6-6.5 m. As a rule, spans in country houses range from 3 to 6 m. For larger spans, additional reinforcement and strengthening of structures will be required.

We use only modern monolithic or prefabricated reinforced concrete floors and practically do not work with floors made of wooden beams or prefabricated reinforced concrete hollow slabs.

All types of ceilings used by us provide sufficient bearing capacity, fire resistance and sound insulation.

Choose a roof

Roofing is an important component of a constructive solution for a future home. Not only the appearance, but also the protection of the building from atmospheric precipitation depends on its choice.

The entire power structure of the roof is made of wood impregnated with fire and bioprotective compounds. The roof structure is designed for any type of roofing.

The roofing itself can be chosen based purely on personal preferences. Of course, you should pay attention to the life of the roof. We use roofing materials designed for a service life of 20 years.

Standard equipment "warm contour"

Select facade

Facade - this is the first thing that draws the attention of any person looking at the house. One glance is enough to tell whether he likes the house or not.

The choice of facade finish depends solely on the personal preferences and financial capabilities of the customer. But regardless of this, the facade, in the solutions we have chosen, will protect the load-bearing structures from the effects of weather conditions.

The fundamental difference in the finishing materials of the facade is masonry or adhesive material. For example, a facing brick is a masonry material; it directly rests on a foundation or console. Decorative plaster or stone is adhesive to bearing walls material that transfers the load to the foundation through load-bearing walls.

Select windows

Windows are an important part of a country house. Through them there is a natural insolation of the premises.

Windows must be of high quality, because. up to 30% of heat loss in the whole house goes through them. For example, the average thermal resistance of the outer wall is 3-3.5 m2C / W, and the windows are 0.6-0.8 m2C / W, i.e. through 1 m2 of the glazing surface, 5 times more heat escapes than through the wall.

This should be taken into account when choosing a project with floor-to-floor panoramic windows; under each window, an underfloor convector should be installed.

Complete turnkey package

Communications

Select communications

1. Installation of heating, water supply, sewerage, ventilation, power supply and lighting systems (if there is a project)
2. Without engineering networks

In modern country house there should be the following engineering communications systems:

Power supply and electric lighting (EOM)

Heating and ventilation (HV)

Water supply and sewerage (VK)

Low-voltage systems (television and internet, various alarms)

Additionally, air conditioning, lightning protection, video surveillance, access control systems can be designed, and all this can be comprehensively remotely controlled through the "smart home" system from your smartphone.

Rough finish

Select rough finish

1. Work on the formation of floor screed, plastering walls and ceilings to the level (if there is a project)
2. No rough finish

More and more innovations appear in the modern construction industry, which are designed to greatly facilitate the work of architects and their clients. This article will focus on such a tool as construction programs, which allow you to determine the main costs, construction time and many other parameters with the necessary accuracy.

Any Internet user can download construction programs for free. Most modern applications are developed and uploaded to the web by popular construction companies, which thus conduct a competent advertising campaign of their services in the domestic market.

As a rule, construction programs of any class have an intuitive graphical interface and many tutorials. Thus, any user of a personal computer can create a 3D model of his dream house without the help of an experienced designer or architect. A secondary program for construction calculations will help to estimate the cost of upcoming work with maximum accuracy.

It is not uncommon for many users, both private and corporate, to use illegal or "pirated" copies. It is important to remember that many building calculation programs from the “hacked” class have an unlimited validity period, but a simplified and truncated set of tools. Because of this, many difficulties can arise not only with the demonstration of the model, but also with its addition or re-development.

Before you look at free building programs, you should consider that professional home modeling and estimating applications have either paid or limited access. Therefore, if you do not need to delve into the basics of the architectural and design profession, you can use free services.

IN this section the main parameters that programs for building design should have are considered.

Construction drawing software

A standard program for construction drawing must comply with all the real laws of physics and take into account the characteristics of each building material. A simplified version of this type of program is Home Plan Pro. With this tool, the user can create a basic blueprint of a house with pinpoint precision, as well as draw up a detailed plan of the interior. To work with this application, you will need elementary skills in drawing and architecture. Thanks to a simple interface, the user will quickly get used to the presented professional environment.

House drawing in Home Plan Pro

And another important parameter of any construction software is a rich set of software tools. The program for construction drawings is equipped with a special constructor, where each element is assigned a place in the appropriate category. Also, when building some structures, any application should provide the user with the opportunity to see how the real model will behave under various weather conditions.
