How to calculate the amount of timber per house, assembling a house from a timber. Approximate calculation of the cubature of timber per house Calculation of timber for building a house

A wooden house has a special attraction. In addition to excellent aesthetics, it has many other advantages, which explains the growing popularity of this type of housing. Preliminarycalculation of a house from a bar will help you accurately determine the upcoming costs and assess your financial capabilities for such a construction.

Types of materials for wooden buildings

Before making a calculation of a wooden building, it is necessary to decide what material to choose for it. Currently, developers are offered the following lumber for this:

1. ordinary (sawn) and profiled timber from solid wood;
2. ordinary and profiled laminated timber;
3. calibrated (rounded) log.

These are the main lumber used in the construction of wooden buildings, but profiled laminated timber is considered the best among them. Its advantages are:

1. minimum residual moisture in the range of 10–18%, practically excluding shrinkage and deformation of wood;
2. ideal shape and exact linear dimensions of the material, which extremely simplifies and facilitates the assembly of the building;
3. increased strength in comparison with a similar bar made of solid wood;
4. no need for additional sealing of the seams between the bars.

These characteristics do not greatly affect the total amount of material for the construction of the building - except that the timber consumption will be slightly lower due to the reduction of waste losses.

Anyway preliminary calculation of a house from a bar at the design stage of the building will allow you to optimize the cost of future construction in terms of quantity and cost of material. In order to correctly calculate the consumption of timber, logs at the first stage, it is necessary to carefully prepare the project of the building and complete its detailing, taking into account the layout, dimensions, places for window and door openings.

General principles for calculating lumber for wooden houses

To calculate the total amount of lumber for a wooden building, you need to divide this procedure into three stages - according to the number of main structural parts of any building. Calculation of a house from a bar made with the following elements in mind:

1. walls and partitions;
2. floors;
3. truss frame.

For each of the named parts of the building, calculations are made, taking into account the purpose of each element. For example, a wall and an internal partition that are outwardly similar are assembled from a beam of different sections, so the amount of material for structures of the same size can vary by more than twice.

Calculation of materials for walls and partitions

Walls and partitions made of timber or logs form a log house. These are the main load-bearing structures of the building, and the walls, in addition, are responsible for its thermal insulation. You can calculate the amount of lumber for walls and partitions using the following algorithm:

1.​ Walls are measured along the outer perimeter and height of the building. The minimum cross-sectional size of a beam for a permanent residence is at least 150x150 mm. In this case, the width of the timber for the first (lower) crown should be greater than for subsequent rows.

2. The volume of material in cubic meters is converted into pieces, based on the overall size of the timber. The resulting amount is rounded up to the nearest whole number.

3. The volume occupied by window and door openings is subtracted from the total amount of material.

4. For piers (partitions) and houses of seasonal residence, a bar with a section of 100x100 mm is quite enough.

Fulfilling preliminary calculation of a house from a bar, start with the optimal wall thickness - this is 200-250 mm. This value guarantees proper thermal insulation, and the walls will not need additional insulation.

If you choose a calibrated log for a log house, then its diameter must be at least 220–260 mm. When calculating a wooden bath, the thickness of the walls from a beam in the range of 125–150 mm or from a log with a diameter of 200–240 mm is considered normal.

Developers who do not have enough experience may need help to draw up a building project, calculate the amount of materials. The easiest way to find it is on the Internet. Here you can buy a finished project, get help in the form of advice on the forums from people who have already put up a log house with their own hands. However, the scope of work on building a wooden house is not limited to the construction of walls.

Calculation of materials for floors

Ceiling and basement ceilings form the volume of rooms (rooms). Their basis is wooden beams, which are based on the foundation and load-bearing walls. To calculate the required amount of material for floors, the following requirements should be followed:

1. the step width between adjacent beams should not exceed one meter;
2. the optimal cross-sectional size of the beams is 100x150 mm;
3. extreme beams should be adjacent to the walls along the entire length;
4. the number of beams, depending on the orientation of their laying, is determined as follows: the length or width of the building must be divided by the step value specified in the project and subtract one unit.

To do it right calculation of a house from a bar from the point of view of the strength of the floors, the operating load of the building should be known or predicted. So it will be possible not to lay down excessive strength characteristics of the beams, saving a decent amount on this.

Beams in a timber house

Where calculations of load-bearing structures are required, it is best to take the help of specialists. This is indispensable when implementing an individual project. The cost of design services is not so significant as not to consider such an option for preparing the construction of your own housing.

Calculation of materials for the truss frame

arrangement of the roof in the house from a bar

Unlike walls and ceilings, the truss frame has a three-dimensional configuration. Therefore, it is much more difficult to calculate it. In addition, it consists of many parts of different sizes, it uses other materials besides timber. The roof design should take into account the following factors:

1. operational and wind loads;
2. type and slope of the roof;
3. type of roofing material and so on.

Fulfilling preliminary calculation of a house from a bar at the design stage of the roof, we must not forget that when building a roof, a bar of different sections is necessarily used. The step width between the rafters should not exceed 70 cm. The ridge beam and Mauerlats have the largest section. The truss frame must ensure the presence of roof overhangs, etc.

In this case, you will need the help of specialists more than ever. For example, you can buy a ready-made house plan from timber or logs to customize it to suit your needs. The main advantage of such a solution is to eliminate the risk of errors, which can be much more expensive than the payment for the received service.

In the calculation of the roof, it is also necessary to include the crate of the truss frame. It can be solid and lattice, depending on the chosen roofing material. Since window and door blocks are most often bought ready-made, this preliminary calculation of a house from a bar can be considered complete. You just have to put the draft notes in order to proceed to the purchase of the necessary materials.

In order for your project to take on the proper form, you must complete calculation of a house from a bar finalization of its results. In the language of professionals, this is called the preparation of a material specification. This document allows you to control the amount of lumber in the range and the total cost of their purchase. The specification is made in the following order:

1. the volume of materials in cubic meters is summarized according to the main parameters, such as the cross-section and types of timber, width, thickness and length of the boards;
2. lumber is converted into pieces, which greatly simplifies the procurement process and makes it easy to control their quantity and assortment.

We want to note that the typical dimensions of timber, logs, boards have multiple values. You must take this circumstance into account when drafting a project. Otherwise, significant waste losses are inevitable. In other words, the dimensions of the log house should be measured in numbers of the same order as standard materials. All the information necessary for this can be found in GOST 8486-86, GOST 24454-80 and other regulatory documents for woodworking.

Final stage calculation of a house from a bar with the preparation of a material specification for the quantity and cost of lumber, it will provide you with indispensable assistance in assessing your own capabilities. At this stage, you can still make changes to the project: for example, reduce the cost of it or, conversely, use better and more expensive materials.

The main properties of wood: useful information

By implementing calculation of a house from a bar, the main characteristics of wood should be taken into account. This will ensure a rational choice of materials and will allow you to perform a number of other important calculations (for example, when constructing the foundation of a house). Among the main properties and characteristics of lumber can be called:

1. residual moisture: it is not recommended to use wood with a moisture content of more than 23% in construction;
2. density - this parameter directly affects the strength of the material and the weight of the building;
3. resistance to moisture, rotting, insects - harms fir trees and other external factors.

In the aggregate of all the features, glued beams are best suited for walls. It has the lowest possible residual moisture, and, thanks to its multilayer structure, it surpasses analogues from solid wood of any species in strength. In addition, glued lumber is usually treated with antiseptics and flame retardants.

For walls and partitions, we recommend using profiled timber. It is significantly more expensive, but these costs will be fully compensated by reducing the time of work, the cost of finishing, insulation and other costs that are inevitable when using lower quality materials. Now you can safely start building.

The calculation technology will differ depending on the number of timber in the batch. For a small amount, it is very simple: if all the material has the same dimensions, you must first multiply the cross-sectional area (it will be equal to the width multiplied by the height of the section) of one bar multiplied by its length. Thus, you find the number of cubic meters of one unit of lumber, after which you multiply the resulting number by the total number of units - this will be the exact cubic capacity of the units of timber you purchased.

It is very difficult for a non-woodworking specialist to figure out how to calculate the cubic capacity of a beam or other wooden moldings. And this is important, since the sale of timber, boards, bars at sawmills and warehouse stores is carried out precisely in cubic meters, which is what many merchants use to earn money in their pocket.

There are at least two fairly simple calculation methods that any non-specialist can master and feel confident when buying lumber for the home.

Calculations for a small amount

As mentioned above, here you just need to multiply the cross-sectional area of ​​\u200b\u200bone beam by its length. For example, 15 units of timber with a section of 150 x 150 mm and a length of 6 meters were purchased. We find the cross-sectional area of ​​\u200b\u200bthe beam - 0.15 x 0.15 \u003d 0.0225 square meters, after which we multiply this area by 6 and get 0.135 cubic meters. - that's how much one beam has. After that, we multiply the resulting number by 15 (the number of timber units) and get 2.025 - the total cubic capacity of the purchased timber.

In such a very simple and accessible way, you can count a small amount of timber and other lumber.

It is also necessary to remember that there are special tables - cubic meters, which will minimize the use of the calculator and greatly simplify the calculations:

- timber 0.10 x 0.10 x 6m - 0.060 cubic meters. - 16.67 pieces per cubic meter.
- timber 0.10 x 0.15 x 6m - 0.090 cubic meters. - 11.11 pieces per cubic meter.
- timber 0.15 x 0.15 x 6m - 0.135 cubic meters. - 07.41 pieces per cubic meter.
- timber 0.10 x 0.20 x 6m - 0.120 cubic meters. - 08.33 pieces per cubic meter.
- timber 0.15 x 0.20 x 6m - 0.180 cubic meters. - 05.56 pieces per cubic meter.
- timber 0.20 x 0.20 x 6m - 0.240 cubic meters. - 04.17 pieces per cubic meter.

- timber 0.10 x 0.10 x 7m - 0.070 cubic meters. - 14.28 pieces per cubic meter.
- timber 0.10 x 0.15 x 7m - 0.105 cubic meters. - 09.52 pieces per cubic meter.
- timber 0.15 x 0.15 x 7m - 0.1575 cubic meters. - 06.35 pieces per cubic meter.
- timber 0.10 x 0.20 x 7m - 0.140 cubic meters. - 07.14 pieces per cubic meter.
- timber 0.15 x 0.20 x 7m - 0.210 cubic meters. - 04.76 pieces per cubic meter.
- timber 0.20 x 0.20 x 7m - 0.280 cubic meters. - 03.57 pieces per cubic meter.

There are times when you need to buy a large amount of timber for your home, while it can be of different lengths and cross-sectional sizes.

To measure and calculate each beam with such volumes is not an occupation for one day.

There is a calculation methodology for such cases, but first we need to understand the concepts of a cubic meter of dense wood and a folding one that exist in forest commodity science.

cubic meter of solid wood

A cubic meter of solid wood is the volume of clean wood obtained by measuring a single bar, excluding voids between the bar and other lumber.

Folding cubic meter

A folding cubic meter is the overall dimensions of a stack of timber, including voids between the timber.

To find the number of storage cubic meters, we stack the timber in a stack as tightly as possible, while the length of the stack should not be greater than the length of the main amount of lumber. Docking of short bars is allowed.

Upon completion, we measure the overall length, height and width of the resulting one or more stacks. When multiplying them, we get the folding cubic capacity of your timber, from which, by means of a special conversion factor, we obtain the cubic capacity of dense wood, for which you pay money.

The value of the conversion factor for lumber is regulated by a number of state standards (GOST 6564-84, GOST 6782.1-75, GOST 6782.2-75, GOST 13-24-86) and ranges from 0.74 to 0.82 for a bar - depending on the moisture content of the bar and the breed from which it is made.

Building a house from a bar is always associated with considerable financial costs. But so that they do not exceed the allotted limit and you have enough materials, you need to calculate the construction of a house from a bar.

Our Remontik portal offers step-by-step steps for calculating a beam for building a house:

	Bar consumption for the house.
	The formula for calculating the material consumption for the load-bearing walls of a building.
	Consumption of material for the roof frame of the house.
	Factors affecting the amount of material needed for a roof frame.
	Calculation of the amount of material for the crate and rafters.
	The number of blanks for the installation of beams.
	Calculation of the number of floorboards.

Regardless of whether you are planning to build housing on your own or for this you decide to hire workers, you need to draw up an estimate. It is she who will be the basis of all work.
A house made of timber contains the following structural elements:

• walls;

• roof;

• logs for floor and ceiling;

• crate;

• rafters;

• fasteners and insulation;

• windows and doors;

• strapping.

Consumption of timber for building a house

For the construction of a house for permanent residence, a beam of 150x150 mm, 150x100 mm, 200x200mm or 100x100 mm is used. Before you start work, you should choose the size of the blanks and calculate how much timber you may need. Usually calculations are made in cubic meters, and not in pieces.

Form for calculating the beam for load-bearing walls

The calculation of a beam for building a house can be carried out according to the following formula:

• to begin with, the sum of the lengths of all the walls of the building is calculated, and not just external, but also internal;
• the perimeter must be multiplied by the height of the house, excluding the gable (the facade of the building, which is limited by the eaves and roof slopes);
• the value you get should be multiplied by the thickness of the timber for construction.

As a result, you will get the number of cubes that you need to build a house. As a rule, they are limited to one or two floors.

As a result, to build a house, you will need 13.5 m 3 of timber with a section of 150x150 mm. If you plan to use more walls, then it is important to take them into account in the calculations.

For the convenience of calculating the construction of a house from a bar and facilitating the choice, you can use the data shown in the table (with a length of 6 meters):

Bar section	pieces per cube	The volume of one piece
200x200 mm	4,1	0.24 m 3
150x150 mm	7,4	0.135 m 3
100x150 mm	11,1	0.09 m 3
100x100 mm	16,6	0.06 m 3

In order to perform the correct calculation of building a house from a bar, you need to take into account what you cannot avoid with individual construction - even a trusted supplier will have several defective units in one batch. This must be taken into account at the time of purchase and order blanks with a small margin.

Roof frame material consumption

For a log house, a truss system is used, which acts as the supporting frame of the roof. Wood is a durable material, but despite this, it should not be overloaded, otherwise it can provoke the destruction of load-bearing walls and uneven shrinkage.

The truss system belongs to the category of pitched roofs. Cheaper and easier to build a gable roof with your own hands. The technology is accessible to a beginner, and it takes much less material.

Factors Affecting the Amount of Material Needed for a Roof Frame

If you want the roof to be not only beautiful, but also reliable, do not save on building materials. It is important not to deviate from the technology when building it yourself.

The frame of a wooden roof contains the following mandatory elements:

• rafters or rafter legs;

• pediment, consisting of a beam similar to load-bearing walls;

• beams (logs) - horizontally located bars, represent the basis for laying the floorboard;

• mauerlat - a thick layer along the perimeter of the walls is used to evenly distribute the weight of the frame;

• crate - fastened to the rafters and acts as the basis for the installation of the roof.

How to calculate the cost of building a quality house from a bar

According to SNiP 31-02, any roof has a number of requirements, taking into account which building materials need to be calculated. That is, in order for the frame to fully comply with the declared standards and provide protection for the house from snow, rain and melt water, and not let cold air through, you need to find out exactly how many blanks are needed.

Calculation of the amount of timber for the frame: Mauerlat

The amount of material directly depends on the coverage area. For example, we can consider a 6x6 house. For a high-quality foundation, you will need a thick, strong timber 150x150 mm or 150x100 mm. It is laid on four load-bearing walls, respectively, to make a Mauerlat, four beams are needed, each 6 meters long.

Attention! If the house does not imply the presence of internal load-bearing walls, then it is important that the distance between them does not exceed 8 meters. If there is another support inside the house, then it is worth increasing the distance to 14-16 meters.

For example: 6+6+9+9=30 meters.

The perimeter, namely 30 meters, must be divided by the length of one bar: 30 m / 6 m = 5 pieces.

As a result, for the construction of a Mauerlat for a house of 6x9 m, 5 bars of 6 meters are needed.

Calculation of the amount of material for the crate and rafters

The rafter system is the main support for the roofing material, which protects the house from snow and wind.

The calculation of the timber that will go to the construction of the rafters is done according to the following formula:

1. The total load of wind and snow per 1 m 2 of the roof - it is calculated on the basis of SNiP 2.01.07-85 "Loads and Impacts". Therefore, for a slope with an angle of 45 degrees, the length of the roof is 6.5 meters and the length of the rafters is 3.5 meters, the load is 226.3 kg / m 2.
2. The total load is 5148 kg. Now we multiply 6.5 m by 3.5 m and we get 22.75 m, which represents the surface area of ​​\u200b\u200bthe slope (5148 kg).
3. Then you need to find out the length of all the rafters and how much timber you need to purchase for their construction. To do this, given that 1 running meter can withstand a weight of 100 kg, we divide 5148 kg into structures and get 51.48 m. This will be the minimum length of the rafters.
4. The slope of the roof hangs over the wall by about 50 cm, which means you need to buy wood of 4 meters.
5. It is very easy to calculate the number of pieces: 51.48 / 4 \u003d 12.87, or more precisely, 14, since they are arranged in pairs. That is, you need 7 pairs.

According to the instructions, the distance between the rafters should be equal to the number that is obtained if the length of the roof is divided by one less than the number of pairs of rafters, namely 6.5 / 6 \u003d 1.08 meters. The cross section of blanks is 150x150 mm or 100x150 mm.

The rafter system also contains a wooden crate. Boards about 2.5 cm thick are used for it. They must be placed horizontally, namely parallel to the ridge.

At the same time, the width of the board should not be more than 15 cm. There are two laying methods, on which the number of timber purchased depends.

The first is continuous laying, when the distance is not more than 1-2 cm and discharged. In this case, the flight can reach 10 or more centimeters. The more often the boards lie, the warmer and stronger the structure, but at the same time, its cost also increases.

Calculating the amount is very easy. The length of the board and skate is measured. Then the installation of the skate must be divided by the footage of the board. Thus, you can find out how many boards were needed for the support strip.

If the width is 15 centimeters, and the gap is 5, then the number obtained after addition must be divided by the length of the slope. As a result, you will receive the number of blanks.

Calculating the cost of building a log house is a painstaking task. Therefore, it is important to take into account the fact that everything must be purchased with a margin. The roof flow rate is calculated taking into account the roof surface area. At the same time, natural openings are not taken into account - a place for an attic door and a chimney door, if there is one in the project.

Overlapping from beams is especially in demand in low-rise construction. They have a relatively low price, they are quick and easy to manufacture, wood is a durable material and has a low weight. It does not give significant loads on the foundation structure.

For the ceiling of the beams, only coniferous wood is used. In most cases, this is larch, since it is the most reliable and durable material that can withstand a lot of weight:

• good resistance to temperature extremes;
• stable tightness;
• practically no shrinkage.

It is worth giving preference to the best blanks that have been dried in steam chambers and have a moisture content of no more than 14%. In this case, the aspect ratio should be the following 150x200 mm or 150x100 mm.

For proper design, in order to perform a competent calculation of materials for the construction of timber, it is necessary to take into account the width of the span. The larger it is, the more often the beams are laid, and their number also increases. To cover the attic, it is not at all necessary to lay the workpieces very close to each other.

We suggest that you familiarize yourself with the table, which allows you to determine how many pieces you will need:

Span width in meters	Distance between beams in meters	Optimum workpiece cross section in mm
3	1	150x100
4	0,5	150x100
4	1	150x150
5	0,5	150x200
6	0,5	150x200
7	0,5	150x250

This means that for a span of 4 m, you need to buy 6 blanks for laying floor beams, starting from a step of 1 m. That is, 4 pieces will be used to close the span and 2 more will go to the edges near the walls. The cost directly depends on the length of the beam.

Calculation of the number of floorboards

Before calculating how much floorboard you need, you should decide on its size:

• the optimal length is 4, 4.5 and 6 meters;
• thickness is represented by the following sizes: 32 mm, 25 mm and 30 mm;
• standard width - 105 mm or 100 mm.

If you are planning to make a floor from whole boards, then it is worth reducing the amount of waste.

The calculation of the material for building a house from a bar is carried out on the basis of the width and length of the covered area and on how the board will spread - across or along.

It is quite easy to do the calculations. If you know the parameters of the blanks, then you will determine the usable area, it is 5-7 mm less than the actual one as a result of the sheet pile.

Typically, manufacturers make boards 6 meters long. You also need to consider the amount of waste that you cannot avoid.

The calculations are performed as follows:

• Divide the known area of ​​the room by the area of ​​the board, taking into account only the useful area - this is the amount needed for laying.
• When the room has parameters other than 6 meters, it is important to consider the amount of the whole material. To do this, the width of the room is divided by the working width of the floor board.

Based on the information received, you can easily find out how much it will cost you to build a house from a bar. At the same time, it is necessary to take into account such consumables as roofing material, insulation and additional fasteners. Their number directly depends on the area, the design of the house and other factors.

Output

Building a house from a bar will be much easier than a brick one, and is available to every novice owner. After completing the construction calculation, you will receive an approximate amount of the object, which you should focus on when planning the budget.

It does not matter whether you have found a decent construction company or decided to make a house out of timber with your own hands - at some stage you just need to calculate the amount of lumber required to build it. What do you need to know for this? Firstly, how much and what kind of timber is needed for the house. Secondly, how much is approximately in one cubic meter. And only then you can carry out a simple calculation of the cost of construction and even draw up an approximate estimate.

We calculate the amount (consumption) of material

Immediately make a reservation that all the following calculations are indicative. More precise volumes of material can be determined based on a specific project. The cubature of lumber on the walls of the timber can be calculated as follows:

• calculate the perimeter of the house;
• multiply it by the height of the floor;
• the resulting value is multiplied by the thickness of the beam;
• as a result, we have the number of cubes for the construction of one floor.

If, in addition to external walls, the presence of internal partitions (also from a bar) is also implied, then they are additionally taken into account. If desired, the material can be calculated not only by volume, but also in pieces, dividing the total volume by the piece.

Let's give a specific example: it is necessary to build a small one-story house 5 × 7 m with a simple attic and one partition. The height of the ceiling is 3 m. In this case, a beam with a cross section of, for example, 150 × 150 mm will be used, and the pediment will also be laid out of it.

Our calculations will look like this:

• the perimeter of the house, taking into account the length of the partition: (5 + 7) × 2 + 5 = 33 m;
• the volume of the walls of the first floor: 33 × 3 × 0.15 ≈ 15 cubic meters. m.;
• we consider the cubic capacity of the beam for the pediment as approximately half of the material required for two walls 5 m long and 3 m high: 5 × 3 × 0.15 = 2.25 cubic meters. m.

In total, about 17.25 cubic meters will go to the walls. m, or, taking into account 20% of the stock, about 20 cubic meters. m. But it should be understood that we did not take into account, for example, floor beams made of glued laminated timber (regular or profiled), as well as other design features. Therefore, you can safely add 5 cubes. As a result of such approximate calculations, it turns out that the construction will take about 25 cubic meters. (But window and door openings, on the contrary, will reduce the need for lumber.)

How many timber in a cube

Simple calculations allow not only to calculate the cubic capacity per house, but also to determine almost the exact number of bars. This is easy to do: it is enough to know the required volume of lumber and the volume of a piece product in order to divide one value by another. Here is a table in which the most common cross-sectional dimensions for a material length of 6 meters.

Beam dimensions

Determining with them, you need to proceed from economic feasibility. It is mostly about the thickness of the walls and the heat-conducting characteristics of the material. Consider this in two variations: a summer (country) house and a building for permanent residence.

Thickness and width

The width of the beam should worry the developer only if permanent residence is planned, and even then not always - after all, any wooden wall can be insulated with effective thermal insulation, thereby avoiding losses for "street heating". For giving, it is quite possible to use a section of 100 × 100 mm. Using the usual unplaned material, you still have to solve issues with facade cladding and interior decoration, dealing, for the most part, with the problems of the aesthetics of the result. But for permanent residence it is better to use a profiled beam with a width of 150 mm or more. In this case, you still have to insulate the walls. As for the thickness, everything is simpler here: the number of beams needed to build walls just depends on it. But, meanwhile, this also affects the number of seams between the crowns. Summarizing the above:

• the thickness and width of the timber for a country house practically does not matter (for seasonal living in the warm season);
• for permanent residence, you can choose a large width, but you still have to insulate the walls. And you can save on cubic capacity by relying on high-quality insulation - it will turn out cheaper and more efficiently in terms of reducing heat losses.

So, in order to build a really warm house without insulation, the thickness of its walls for the Moscow region should be about half a meter. The same effect will be when using a beam of 150 × 150 and 10–15 cm of thermal insulation.

We draw your attention to the fact that not all lumber manufacturers and sellers are honest with their customers: you can often encounter an underestimation of the declared section. For example, a 150 × 200 beam actually has a section of 140 × 190 or even less. Be sure to check the actual parameters before buying! This will help you not to get into a mess, save money and nerves!

estimate

Before deciding on the choice of builders, monitor offers. To determine the most cost-effective option, ask various competing firms for their estimates for the selected standard or individual project, which includes all costs: both the cost of building materials and the payment for all types of construction work.

Normal companies offer such estimates for free. It is noteworthy that for different firms the final amounts for the same buildings can differ not only by 10-20%, but also several times. It is advisable to have on hand the most detailed list of works and materials to implement your idea - this is the only way you can avoid additional, unforeseen expenses along the way.

If desired, the estimate can be compiled independently: by calculating the consumption of materials, multiplying the results by average prices (in total, these will be the costs of building materials) and adding about 50–100% of this amount to pay for work. Such an approximate calculation can be used to analyze proposals from specialized companies.
