Construction calculator - tell your friends!!!

If you are looking for design documentation for construction or competent builders who can build a durable and high-quality house, we recommend that you first obtain high-quality and professional advice from specialists from the following companies.

Construction work largely depends on the correct preliminary calculation of all necessary materials. Since a very large number of different types are used in this area, it is not possible to immediately come to the store and say: give me this or that, so that there is enough.

Before purchasing materials on the website pyramida.kh.ua, you should first evaluate the entire scope of work and roughly estimate how much to buy. There are many rules on how to correctly count such purchases.

Let's start the calculations

Performing calculations is a fairly simple process, but there are certain rules you should know when doing them. Each type of material has its own specific technique, which is tailored to certain conditions.

Today, to facilitate such procedures, you can use special services on the Internet, where you just need to indicate your parameters and the calculator will give you the required amount.

But to understand how this procedure occurs, let’s consider the basic rules for calculating some building materials:

• Concrete is always calculated according to the required volume. To do this, you first need to know this parameter. The volume itself is calculated based on the amount of crushed stone.
• Putty. The consumption of this material varies, but in most cases it is indicated on the packaging. To find out the full volume of material required, multiply the working area by this parameter.

In construction, there are many different materials that are used as finishing. To find out the required quantity of some of them you need:

• Tile. When calculating the number of pieces required, you first need to know the area (wall, floor). After this, you need to calculate the area of ​​the material itself (the area of ​​1 tile) and then divide the total parameter by the last number found. To find out the exact quantity, you need to round the resulting parameter to the nearest upper number.
• Wallpaper. Calculating the required number of such products is not difficult and roughly boils down to the previous technology, where you need to find out the total area, height of the walls, length and height of the walls. The height of the ceiling often plays a role, since the length of the roll is not always a multiple of a certain number of strips, which can lead to large residues.

When calculating all building materials, the entire procedure boils down to finding the required quantity and calculating them based on average use for a certain volume, area, etc.

The best way to quickly estimate costs

Before you begin the pleasant and at the same time exciting procedure of building a future family nest, you need to conduct a financial analysis of the issue and clearly define the acceptable level of expenses for creating a residential building. If you have already decided on building materials, then an approximate online calculation of the cost of construction can be made directly on the company’s website. An intelligent calculator will allow you to create a preliminary estimate online, while it will take into account the area of ​​the house, the type of foundation, the material of the walls and roof.

In addition, you can choose one of two options for finishing the facade, installing heating, electrical, water supply systems, and add to the estimate the costs of additional insulation and autonomous sewerage. The cost calculator for building a country house will take into account all your wishes and display the approximate cost. Of course, the geolocation of the site, the season of work and the complexity of the project will adjust its cost. Therefore, we recommend contacting the company manager to clarify the estimate.

If earlier the choice of what the house would be like was small - from wood or ashlar, today there are plenty of materials, and an accurate calculation of what and how much is needed is required, that’s why it’s needed construction calculator.

In what cases and how is a construction calculator used?

Even if you have not yet decided what materials the house will be built from (and there are plenty of options: brick, silicate or aerated concrete blocks, logs, timber or boards on a frame), the principle will be similar. First, the foundation is made, then the basement, in the process the basement and possibly the basement are formed, then the walls grow, the floors are laid, the rafter system is built and the roof is laid. Everything is simple and, at the same time, very complicated when you consider how many different building materials need to be purchased, transported and placed on the site. And if something is missing, should I go again, look and buy?

So that there are no incidents with a lack of bricks or boards, an online construction calculator is used, that is, a special service on the Internet that allows you to make calculations in a matter of minutes.

However, it is impossible to provide for everything in such a program, because house designers often come up with something new, and you may have your own ideas. Therefore, you need to know how to calculate the material for a house using a pen, a piece of paper and simple arithmetic. You will have to operate with such values ​​as length, width, height and volume, as well as linear meters and area (including sections of a particular material).

The foundation is calculated quite simply, you just need to determine the volume of the future fill, decide in what proportions you will mix the solution, and then calculate the construction of the house. Let's say you want a strip foundation for a small cottage 6x5 meters, divided into 2 rooms, the width of the base will be the same as that of the walls, for example, 40 centimeters, the depth is half a meter. It is not difficult to calculate the volume of fill, multiply 40x50 and get the cross-sectional area, then multiply by the length of the walls (2 x 6 meters and 3 x 5 meters). Since we count in meters, it comes out to 0.4. 0.5. 27 = 5.4 cubes of solution. This will help you on how to calculate the amount of materials.

Calculation of construction of a house with brick and block walls

Not everyone likes a log house, and many find the brick option more practical, especially since well-made masonry has fairly high thermal insulation properties. Typically, walls are built with one and a half bricks, sometimes two; there are other types of masonry, for example, two walls with a void between them filled with bulk material that plays the role of insulation. Building blocks are purchased by the cubic meter, and it is advisable to know exactly how many stacks will be needed for the job. It’s even better to decide in advance on the number of bricks. How? Calculating the construction of a house in this case will be very simple.

Previously, we looked at strip foundations, but why are walls worse, the thickness of which also allows us to calculate their volume? We proceed in the same way, not paying attention to the error arising from the masonry joints (it is better to make them thin so that cold bridges do not arise). Knowing how to calculate the volume of a house, we can easily find out how many cubic meters of brick will be needed. It remains to determine the volume of one piece, divide the first number obtained by the second, and we will find out the required number of bricks. As for expanded clay concrete blocks, since they are exactly 7 times larger in size, there will be just as many fewer of them.

Calculation of frame-type building structures

The greatest difficulty for calculations is presented by frame houses that are now becoming fashionable. The fact is that such structures are quite complex, and only a designer can say in advance how much timber will go into the frame, which will later be sheathed with boards. But it is still possible to calculate a frame house, since the construction of this structure is subject to certain rules. The basis of everything is the lower belt, in the form of a frame made of timber with crossbars, which will become the ceiling of the first floor in the future. Next, corner posts are installed, the cross-section of which depends on how many levels the building is supposed to have. For a two-story house, it is advisable to install the supports from 150x150 millimeter timber.

The number of linear meters of material required for the bottom trim is calculated using the formula: (a+b) . 2, Where a And b– lengths of the sides of the house. The result will be, in fact, the perimeter P the buildings. Let's add crossbars here that will correspond to the shorter wall, let's say it will be a, then the formula will change to this option: P = ((a+b) . 2) +n. Here n– number of crossbars laid in increments j, this value is calculated using the formula: n=b/j – 1, one must be subtracted because the last cross member is already taken into account in the previous formula, being one of a-sides The height of the lower belt is two beams, based on this, taking into account the above formulas, it is possible to calculate the construction of a house from lumber.

Then a power frame is built, consisting of vertically installed supports, the spacing between which is half that of the base crossbars. In other words, their number can be derived from the previously given formula by slightly changing it: n = ((a+b) . 2)/(j. 0.5) – 4, the last number corresponds to the number of corner posts. Where doors and windows will be located, the supports are skipped, therefore, the formula must include subtracting the number of such planned openings. The windows are delimited by two cross beams, the doors by one at the top, in addition to the horizontal beams that top the load-bearing frame of the first floor. For the second floor, the calculation of building structures is done in a similar way, but we will not talk about the rafter system here, it requires separate calculations.

How much does it cost to build a house - the calculator will give you the answer

In general, the pitch, both for the jumpers of the lower chord and for the racks, is selected based on the dimensions of the cladding materials. For example, if the length of the exterior finishing board is 1 meter, and the thickness of the support beams is 15 centimeters, then the step between them should be 85 centimeters so that the elements of the nailed sheathing are joined exactly in the middle of the racks. You should also take into account the standard sizes of the internal cladding, in particular, plasterboard sheets have a width of 60, 80 and 120 centimeters, and it is reasonable to adjust the pitch of the beams to these indicators.

A wooden I-beam, which is just beginning to be actively used in construction, is very convenient. Made from two horizontal bars connected by an OSB bridge, this material provides ready-made cells to be filled with insulation.

The cost of one cubic meter of timber is not difficult to find out, but how much it will cost to build the frame is a completely different question. However, given the dimensions of the lumber and the number of racks, anyone can easily calculate the total volume of wood. To know how to build a house, you need a separate calculator for each material, in this case for timber. Next, you will need to calculate the insulation, determine the area of ​​​​waterproofing, windproof membranes, vapor barriers, and calculate the amount of finishing material. For example, based on the thickness of the beam of the load-bearing frame, it is better to choose thermal insulation 2 times thinner and lay it in two layers, this will provide an additional air gap, which, in combination with the overlap of the mats, will give a greater effect. Moreover, the price depends not on the thickness, but on the density of the material.

Regardless of whether you want to build a house from timber or brick, you definitely need calculation of building materials, which will be used for the foundation at the beginning and finishing at the end, not to mention the roofing.

You are about to build a house. This is a very serious undertaking and, undoubtedly, you decided to approach it with all responsibility. This means that it must be decided what the external and internal walls will be made of, what kind of ceilings and floors there will be (this is not always the same thing), what material will be laid on the roof. If the cottage is made of brick, this does not mean at all that you will not need boards or hardware. Therefore, we begin to compile a list of everything necessary in order to then calculate the building materials.

Foundation calculator

The foundation is the basis of everything, so let’s look at it first. There are options here. Most often, in order to save money, a tape type is made. That is, a ditch is dug strictly along the perimeter of the building, which is filled either with ready-made reinforced concrete blocks with additional cement filling, or simply with concrete mortar. Therefore, you at a minimum need sand, crushed stone and water in certain proportions. To lay blocks, which are quite large in size, into a trench, you will need to use a crane. A columnar foundation is less commonly used, which will save a lot of building materials; even less often, houses are built on wooden piles, which are separate beams or logs.

Next, you should make calculations for the walls, including the plinths. Different types of blocks, timber or logs are used for construction. Determining the amount of materials for each of the listed options is carried out separately, however, the formulas for woodworking products are quite similar. Since beams, as well as bricks, are sold by cubic meters, you will have to operate not only with areas, but also with volume, correlating these completely different units of measurement. The main difference in determining the number of building blocks and is precisely in the area of ​​the walls, since for the first all openings can be subtracted, but for the second they will have to be included in the cost.

The calculation of rafter legs can be performed separately or combined with the calculation of the amount of timber for building a house. In addition, it is quite possible that the project will include metal trusses, which means it will be necessary to purchase hardware, at least a corner, or pipes with a square or rectangular profile. This will require additional calculations of rolled metal, especially with regard to the resistance of the structure to loads. The amount of roofing covering is calculated separately, based on the roof area and its shape, for example, a multi-gable version will require more materials due to the high percentage of waste.

The foundation of any building must be reliable, and if the cottage is built from ordinary brick or gas silicate, we discard the piles immediately. Let's focus on strip and columnar foundation options, without reinforced concrete blanks, so as not to involve equipment. Typically, pouring under a house is done in a ratio of 1:3:5 or 1:4:4 cement, sand and crushed stone, respectively. It is much more important to choose the right amount of water; for this, the W/C ratio is used, that is, dividing the volume of water by the mass of cement. You can also use the table of ready-made W/C results, thanks to which, knowing the amount of cement, it will be easy to calculate how much water is needed:

Concrete grade
Cement brand
300	0,75	0,65	0,55	0,50	0,40
400	0,85	0,75	0,63	0,56	0,50	0,40
500		0,85	0,71	0,64	0,60	0,46
600		0,95	0,75	0,68	0,63	0,50

The volume of the strip foundation is determined by the formula V=SL, Where S is the cross-sectional area of ​​the fill, and L– its length, consisting of the perimeter of the building, added to the lintels for the internal walls. A columnar foundation is defined in a slightly different way; the formula looks like V=SHn, Where S– cross-sectional area of ​​the support, H is its height, and n– number of pillars. The cross-section of a square or rectangular base is determined by the formula S=ab, Where a And b– lengths of the sides. The round cut of the support is calculated as follows: S=πR 2, Where R is the radius, and π – constant equal to 3.14.

The number of blocks that will be needed to build walls can be calculated in several ways. It is usually known in advance how many units of ordinary brick or gas silicate are in a cubic meter. Now it is enough to find out the volume of the walls, for which we multiply the area of ​​each by the thickness and subtract from the result the sum of the areas of window and door openings. However, in this case the result will be slightly overestimated, since we did not take into account the angles. In order for the calculation of building materials to be correct, we determine the error. It is enough to carry out the same calculations for the area of ​​the internal walls and subtract the second result from the first. Now all that remains is to multiply the total by one cube, and we get the total amount of materials. You can also use the table:

Number of blocks in 1 m2 of masonry

Type of masonry	Brick size	Quantity excluding mortar joints, pcs.	Quantity including mortar joints, pcs.
0.5 bricks	single
	one and a half
1 brick	single
	one and a half
1.5 bricks	single
	one and a half
2 bricks	single
	one and a half
2.5 bricks	single
	one and a half

If you want to build a good-quality log house or a small bathhouse, you will need to determine the height of the building in the crowns, which will build up the walls row by row. But, first of all, it is recommended to find out how many beams or logs, given their dimensions, are contained in one cubic meter. If the cross-section is large enough, rest assured that the number of woodworking products will amount to only a few units. Let's start by determining the volume of one product, with an eye to the cross-sectional shape.

For timber, the formula will be simple: V=abl, Where a And b– sides of the section, and l– length of lumber. For a log, the calculation will be different: V=πR 2l, Where R– section radius. If all parameters are taken in meters, then the result will be in cubic meters. When purchasing, you should do the full calculation, as some sellers tend to reduce the volume to whole numbers if the end result is a decimal.

We have a formula of the form V=HPb, Where H– height, and P– perimeter. The total number of beams is calculated by dividing the result by the volume of one product with a rectangular cross-section. With a log it is somewhat more complicated; here you should multiply the number of crowns by the number of walls, including internal ones (a typical option is a five-walled structure), and then by the volume of one rounded lumber. There are usually as many logs in the crown as there are walls in the building. For more complex cases, you will need a building materials calculator.
