There is hardly a family who would not dream of living in their own house somewhere near the city. The cost of such housing can sometimes be quite comparable to the prices of city apartments, and the advantages of owning your own plot of land are obvious. Therefore, more and more families are thinking about leaving the city and building a home in its surroundings.

However, in our unstable times, building a private house is perceived by many as a very risky undertaking. What if prices for everything increase dramatically, or additional costs arise during the construction process? Is it even possible to stick to a pre-set budget? If you approach the construction budget wisely, then everything may not be so scary.

Drawing up estimates will become a much simpler process if you entrust this task to professionals.

Estimate for building a house. What it is?

The construction estimate is a preliminary calculation of all costs. Usually the estimate is a simple table that takes into account the main cost items:

• Cost of materials
• Cost of work
• Cost of delivery
• Overheads

Here is an example of what a standard cost estimate table looks like:

As you can see, the basis of the estimate is simple mathematics: the cost of one unit of material must be multiplied by the required quantity, and we will get the total cost. The difficulty lies not in the calculations themselves, but in including in this table everything that is needed to obtain an accurate picture.

The meaning of the estimate is to calculate in detail how much money will have to be spent at different stages of construction. The ultimate success largely depends on this. If you neglect calculations and estimate costs “by eye,” money will most likely slip through your fingers, the process will drag on, and the budget will grow uncontrollably.

If you are working with a contractor company that controls the construction process itself, then it must draw up an estimate and show it to you personally. It is expensive, and you can easily be deceived by slightly inflating the prices for materials or work. Many people decide to deal with all issues themselves and hire only teams to perform specific work.

In this case, you will have to draw up an estimate yourself. There are many companies that do this professionally, but it is quite possible to save money on this if you take a serious and thoughtful approach to drawing up estimates.

Drawing up an estimate. Algorithm of actions.

If you don't know where to start when creating an estimate, it is useful to have a rough sequence of actions to follow. Drawing up an estimate for construction can be divided into several stages.

1. Drawing up a work plan.

At this stage, your task is to determine the sequence of all the work that will be performed during construction from start to finish. This will help you navigate the construction process. In this case, it is necessary to indicate the timing and duration of the work, and also include technological breaks in the plan, for example, for hardening of concrete floors or screeds.

Such planning is very important, it will help not delay construction. The plan can also indicate in advance what work you will do on your own, where relatives will help you, and where you will hire a team or special equipment. These construction stages can then be reflected in the estimate, or estimates can be drawn up separately for each stage.

The main points of such a plan usually look like this:

• Laying the foundation
• Construction of a box: walls and ceilings
• Roof and chimney
• Installation of stairs, windows, doors
• Summing up communications
• External and internal finishing

2. Calculation of volumes of materials and structures

Which materials and structures to use and how much depends mainly on your project. Thus, you should start drawing up an estimate only if you already have a ready-made house project that you are completely satisfied with.

Then, having the exact parameters of your future home, taking into account technology and building codes, you can calculate the approximate volume of material used at each stage of construction for each type of work. This will take quite a lot of time, but this is the basis of the estimate, so the calculation must be done as thoroughly as possible.

For this purpose, there are so-called construction calculators - online services or programs that automatically calculate the amount of materials based on the parameters of the house. You can also find statistical data on this topic on various construction forums on the Internet.

If your project is typical, then such a calculation will not be difficult at all, since most likely, data on materials and structures are already available for it.

3. Price analysis.

Once you have decided on the volumes, the next logical step is to find out the current prices for materials and work. This will not cause you much difficulty. All you need is to make a small list that will include the main companies on the market of building materials and services in your city, and monitor their price offers. You can call them and ask them to send you the current price list or find it on the official website.

You can enter average or maximum prices into the estimate. You will probably change suppliers as you work, so having an idea of ​​the average prices in the market will be extremely useful for you. It is better to conduct such an analysis approximately once a month and adjust the indicators as construction progresses to take into account price fluctuations. Don't forget about shipping costs.

4. Table and calculation.

When all the initial data is ready, you can enter it into the table and count it. It is important to note: the figures obtained will only be intermediate results. Anyone who has been involved in construction knows that the estimate will change in any case and, as a rule, upward. There are always factors that affect costs: defective materials, errors in work, force majeure, and so on.

An example of calculating an estimate for the construction of a private house with a total area of ​​323 m2

In order to make calculations more accurately, it is advisable to select a multiplying factor that will take into account unforeseen expenses. You can choose the value of this coefficient at your discretion, taking into account your finances. This way you can, if not completely avoid an increase in the estimate, then at least minimize it.

If you have thought through everything and drawn up a detailed estimate, most likely you will stay within budget, and if there are deviations, they will not be critical. It is important to calculate the full estimate before starting work in order to decide whether it is worth starting at all.

Remember that if you lack funds, you can postpone some work until the future, when money becomes available. For example, if the box is ready and the heating circuit is closed, some people are already moving into the house and gradually finishing everything else.

Anyone who wants to build a house or renovate an apartment initially calculates how much it will cost him. For complete clarity, it is necessary to draw up a list of necessary materials and work, as well as their cost. Based on this, you can find out how much money you will need. And also decide whether to involve builders or do everything yourself. Not everyone knows how to draw up an estimate, what items to include in it and how to calculate everything correctly. Let's try to figure this out.

What is an estimate

An estimate is a document that systematizes all costs for upcoming construction or repairs. You can easily do this yourself, without having specially developed programs.

How to make an estimate on your own? All you need is Excel on your computer. Calculation of funds and materials must be done very carefully to avoid mistakes and exceeding planned costs. It should display everything down to the smallest detail.

Common mistakes

When drawing up estimates, many make mistakes, which then come to light and provoke unforeseen expenses:

• Calculations are carried out without a preliminary inspection of the facility where the work will be performed.
• Additional expenses that may arise due to force majeure circumstances are not included.
• The full list of works and materials is not taken into account.

The main expenditure document for repairs or construction requires a serious approach and accurate calculations. Otherwise, you may get incorrect results.

What is necessary for competent budgeting

Before drawing up an estimate for construction or repairs, you first need to inspect the property. After this, you should make a list of all the work being carried out.

How to make an estimate correctly? You need to know construction technology. Without this, it is impossible to competently and correctly calculate and record all upcoming expenses. Therefore, we recommend that before drawing up an estimate, you study the sequence of the production cycle of the work that needs to be estimated. This will help to understand the need for operations and the need for building materials.

Main items of the estimate

Any construction estimate consists of three main items:

• materials;
• Job;
• transport.

All other items (cost of electricity, equipment operation, etc.) are added to them.

The first position indicates a list of necessary materials for each cycle of work, unit of measurement, quantity and price. For example: brick, glue, plaster, cement, wallpaper, linoleum and others. This also includes “consumables” (brushes, rollers, gloves, etc.). Before making an estimate, find out the cost of materials directly in the store, or search on the Internet on sites specializing in the sale of building materials.

The second position includes a list of all actions performed. Here it is necessary to take into account both preparatory and finishing work, their complexity and the conditions in which they are carried out. For example, you need to cover a room with new wallpaper. To do this, you will need to carry out preparatory work: remove the old coating, clean the walls, prime them. The approximate cost of the necessary work can be found in the advertisements.

The “transport” position includes: delivery of materials, unloading, removal and removal of construction waste, indicating each item on a separate line. Information on the cost of these services is provided in the companies' price lists.

Drawing up an estimate for apartment renovation

How to correctly draw up an estimate in order to carefully plan renovation work in an apartment and complete it in a short time with minimal costs? First you need to decide what kind of repair you will do: cosmetic or major. The amount of materials needed and the amount of work depend on this. If you decide to carry out a major overhaul, the estimate should be divided into two parts:

• repair and finishing works;
• roughing and finishing materials.

How to learn how to make an estimate to avoid mistakes? To do this, you should inspect all the premises of the apartment, measure the surface area of ​​the walls, floors, window slopes, make a list of finishing and rough materials, determine the cost and scope of work for each room separately.

Example

Let's give an example of how to create an estimate for repairs. Prices and material consumption are fictitious.

Repair and finishing works:

Consumables and finishing materials:

Transport:

To get preliminary results of apartment renovation costs, you need to add up the totals from each column.

18819 + 7870 + 4000 = 30689 (rub.)

You should know that the final costs are always 10-15% more.

30689 + 15% = 35292.35 (RUB)

The principle of calculating construction costs does not differ from the estimate for repairs. Only production cycles and materials will change. How to create an estimate for construction with minimal costs? To do this, you need to carefully plan all the work, clarify what materials will be needed, and find out the prices.

Drawing up an estimate is a very important stage from which you need to begin any repair or construction. A correctly drawn up document will help you carefully plan and rationally distribute costs - both material and money. The main thing is to take the calculations seriously and perform them as accurately as possible.

The choice of foam blocks indicates the owners’ desire for reasonable savings. But in order to fully realize the benefits of this solution, you need a correctly calculated construction estimate. Firstly, it will allow you to anticipate future expenses and compare them with the accumulated amount. And secondly, a detailed list of materials will help find a way to reduce the cost of building a house without compromising its reliability and appearance.

When you are planning to build a house, you first need to find a suitable project. Only if you have a diagram of the future housing, you can choose the optimal location of engineering systems, calculate the quantity and price of materials for the estimate, and determine the order and timing of the work.

Let's take as an example the construction of a 6x8 country house with a small terrace and a residential attic. The picture shows a sample layout of a cottage made of foam blocks:

To simplify further calculations, it is convenient to divide the construction of a house into several main stages in order to find out the approximate quantity and cost of materials for each.

Walls

After studying the project with all the applied dimensions, it is already possible to determine the number of foam blocks and derive the approximate cost of building the “box” of the house.

Sample wall calculation:

1. Determine the main dimensions of each surface from the plan and calculate the area of ​​the foam blocks (without openings).

Multiplying the result by the required thickness, we obtain the cubic capacity of foam blocks measuring 600x300x200 mm:

• 99.4×0.3 = 29.8 m3.

2. Using the same principle, we determine the number of blocks for the construction of interior partitions. Here you can save a little due to the smaller thickness and use stones with dimensions of 600x300x100 for construction.

• 36×0.1 = 3.6 m3.

3. The consumption of the adhesive mixture per cube of foam blocks varies significantly depending on the thickness of the seam. On average, you can start from the figure of 18 kg/m3.

4. Reinforcement is performed in every 4th row of masonry. With a block height of 200 mm, the rods will be located at a distance of 80 cm. That is, to build 3-meter walls from foam blocks, four horizontal armored belts will be needed.

Rental consumption for each of them:

• Load-bearing walls - d-8 rods with a total length of 2x28 m.
• Partitions – 2x20.6 m.

The estimate must take into account reinforcement overlaps, which can significantly increase the consumption of rolled steel, but everything will depend on the length of the available bars.

To strengthen window and door openings you will need special U-shaped foam blocks. There are 8 lintels in our example, plus 2 more above the attic windows. But since the special blocks are only 50 cm long, they will have to be laid in a row of two. A total of 20 units with internal reinforcement of 4 rods each (80 m) will be required. The diameter of the rods is determined by the current loads, but d-6 or d-8 is usually sufficient.

Construction of the foundation

The foundation for a lightweight house made of foam blocks, built on dense soil, will not be too expensive. A one-story building can even be installed on poles, if the soil allows it, and for more difficult construction conditions, a monolithic reinforced concrete strip is suitable. We include it in the estimate as a sample.

We take the depth to be 60 cm plus 40 for the base part, and the width of the tape will depend on the masonry method and the chosen wall finish. For a house made of foam blocks with brick lining, when built with half a stone, you need a strip foundation half a meter thick. According to the project, its total length will be 48.6 m.

Material consumption for construction:

• 195 m of d-10 reinforcement and 253 m of d-8 vertical jumpers, plus 220 m of tying wire.
• Concrete M300 (it is better to specify the brand when calculating the weight of the building) - 24.3 m3.
• Sand and gravel (2.5 m3 each) to form a cushion, wooden formwork.

All bulk goods must be ordered in reserve, as they are partially lost during unloading and during construction. Reinforcement is purchased taking into account the loss of footage at overlaps.

Roof

A simple and neat option for building a house is a gable roof. Its entire frame will be made of lumber of various sizes, which will not place excessive load on the foam block:

1. Mauerlat 28 m – timber 150x150.

2. Ridge 8 m – beam 120x150 mm.

3. Frame - taking into account the outlets, you will need a 4-meter beam of 50x150 mm with an installation step of approximately 1 m. That is, you will need to form at least 9 pairs of rafter legs (72 m or half a cube of timber).

4. The logs for the attic floor can be made from 100x150 mm timber, but you will have to look for 6-meter products. Their construction will require 0.7 m3.

5. 30x100 mm boards for roof sheathing and floor/ceiling installation on wooden floors are calculated based on the area of ​​each surface.

The arrangement of the insulating layer and the choice of roof covering is at the discretion of the owners. We insulated our sample with mineral wool and a wind-moisture-proof membrane over the entire area of ​​two slopes (64 m2); We will cover it with metal tiles.

Finishing work

The most inaccurate point, due to which the estimate for building a house made of foam blocks can increase by one and a half times. Whether it is ordinary plaster or facing with expensive facade bricks is not so important - only the appearance of the house depends on the final choice. The main thing is that the foam block is under reliable protection of breathable and waterproof coatings.

On average, turnkey wall cladding, taking into account materials, will result in the following amounts:

• decorative brick – 1100 RUR/m2;
• siding – 820 r/m2;
• plaster – from 380 RUR/m2.

If you do it yourself, you will only have to spend money on purchasing the selected finish. However, these expenses are not considered urgent. While the foam block house remains standing after construction (6-9 months), the required amount can be saved. The same amount of time remains for ordering windows and doors, since it is better to take all measurements after settling.

Cost calculation

Of course, estimates for construction work require a lot of experience and professionalism. But if you decide to build a house yourself, you don’t need impeccable accuracy of calculations. It is enough to take into account the main expense items for your project and make obvious amendments:

The amount we have derived takes into account only the most basic expense items, but even this is not the minimum. A detailed estimate for the construction of a house made of foam blocks includes many additional items, such as:

• delivery price;
• fasteners, embedded and connecting parts;
• mandatory stock of bulk and piece materials, solutions, fittings;
• impregnation for wood;
• sealing tapes and sealants;
• insulation of the foundation and floors (if necessary);
• connection of communications and turnkey finishing;
• prices for the services of contracting teams.

Individually, these points seem insignificant, but experienced estimators know that about 50% of the cost of basic materials is spent on such related expenses.

Is it possible to save money?

The main path to savings is the correct choice of foam block sizes for construction. In the central and northern regions, where heat retention in the house depends on the thickness of the walls, it is better to use foam concrete blocks 600x200x300 mm. With this aspect ratio, they can be laid in different ways, changing the thickness of the box in 10 cm increments. In this case, the number of stones will be the minimum possible - without reserve, or rather, without overspending.

You can save on the cost of the blocks themselves only in one case if you buy them directly from the manufacturer and in full. But trying to reduce the cost of building a house by purchasing cheap, low-quality stones is not worth it. Incidental costs to give crooked masonry a normal appearance will “eat up” the entire difference and may even exceed the estimate. Another important nuance is the choice of masonry mixture. Special compositions for foam blocks, only at first glance, will be more expensive than a regular solution. In fact, their consumption is almost an order of magnitude lower, and such masonry retains heat better.

If you order an estimate from a contractor, it makes sense to contact several companies or use online calculators. Prices are different everywhere, so you can find the most affordable option or adjust it at your discretion.

The construction of a house or building begins with calculations and drawing up an estimate, taking into account the materials used, the work performed and the cost of renting special equipment. That is why in construction it is customary to use estimates that clearly reflect the financial costs of constructing a specific object. The estimate applies to all types of buildings. In this article we will tell you what a house estimate is and how it can be calculated, as well as how much it costs to calculate an estimate.

Composition of the construction estimate

An estimate for the construction of a house is the main document for specialists; without it, not a single developer will carry out the construction of a building. The main financial costs fall on the purchase of building materials and additional elements for them. When calculating estimates, you should take into account such parameters as:

• volume of planned work;
• technology used;
• construction time;
• number of specialists on the project;
• volume and terms of financing of the facility.

These criteria will allow the customer to monitor the timing of the construction process and check certain types of work. The main task that the estimate for building a house solves is:

• adherence to a clear work schedule;
• amount of financing during the period of work.

To perform calculations, the customer can submit applications to several companies at once; to do this, it is necessary to conclude an agreement for the preparation of the document. As a result, a house estimate compiled by different specialists will differ in the final cost, this is due to the fact that each company contributes its suppliers of materials and specialists performing the work. After reviewing several documents, you can compare and choose for yourself the most optimal option in terms of money and without compromising the future design.

Be sure to include minor or unexpected expenses at 15% of the total cost of the property. This may include transportation costs, payment for obtaining various certificates related to construction.

Acquisition of land and performing calculations

Construction costs, as a rule, begin with the inclusion of the cost of the land plot in the expenditure part of the document. Land is acquired in several ways that do not contradict the law:

• purchase of a plot from the previous owner;
• redemption from state property;
• obtain a plot of land free of charge, subject to the availability of free land.

When purchasing a plot of land, be sure to draw up an agreement; this document will help you avoid fraudulent transactions and protect you legally. The contract must contain:

• subject of the agreement: purpose of the site, its category and total area;
• the price of the plot agreed upon by the sellers and the buyer.
• When the transaction has already been completed, state registration of the transfer of ownership rights is carried out. For this, the following documents are submitted to the justice system:
• application-registration;
• receipt of payment for registration of the site;
• purchase and sale agreement;
• passport and additional identity documents;
• cadastral plan.

The entire package of documents is accepted by the relevant authority and the decision is made within the period established by law, which is one month.

For information! When several construction processes are carried out by different contractors, it is necessary to prepare estimates for construction work for each type of work.

The price of such a document can vary from 9 to 40 dollars, because... The calculation depends on the number of positions in the document. The period for drawing up documentation is from 1 day, depending on the urgency.

How to make an estimate

Calculating future construction costs is a matter for specialists, but if you are confident in your abilities, you can draw up an estimate for construction yourself. The photo shows an example of an estimate for the construction of a frame house. Procedure for drawing up the document:

• decide on the amount of materials;
• find the necessary equipment;
• negotiate with construction specialists.

When you already have an idea of ​​what the house will be built from, what it will look like, in which part of the site it will be located, what materials will be used, it will not be difficult to calculate the final amount. It is worth noting that there are now a large number of construction forums on the Internet where you can download a blank estimate document form or compose it yourself in an office program.

So, how to make an estimate for the construction of a wooden house? To prepare a cost estimate you must:

• Decide on the sequence of actions, understand what work should be entrusted to construction organizations, and what you can do yourself.
• The following is the calculation of the estimate, depending on the use of construction technologies. It consists of determining the volume of building materials and structures and their application.
• When all this data is already available, you can find a company providing construction services, look at the prices, and find out the cost of materials and work.
• Next, the component takes all the obtained values ​​and transfers them to its table, where the totals will be summed up for each type of work or product.
• When all the data is filled in in the columns: name, cost of work, unit of measurement, you can perform a general summation of the project. For convenience, you can put the final figure on the right side of the table; for this you need to configure the formula. This calculation can be performed for a structure made of any material and design.

In a similar way, they calculate the amount of materials and the amount of work for all types of houses, regardless of what they are built from.

Cost calculation for foundation, roofing and finishing materials

The estimate for construction work must necessarily contain information about the foundation, roofing and finishing materials; these items are the most expensive. In order to understand how to calculate the volume of material for the foundation of a house, you should multiply the perimeter, height and thickness of the foundation. As a result, we will get the volume and find out the cost of 1 cubic meter. m of concrete and multiply it by the resulting value. It is very easy to calculate the roofing material; for this you need to take the total roof area and the cost per 1 sq.m. from the project for the house. material, and then multiply them together. Calculating the cost of finishing is the most troublesome task; for this you will need to multiply the wall area by the cost of 1 sq.m. each type of product.

We invite you to watch a video that shows how to calculate estimates

The choice of foam blocks for building a house indicates reasonable savings for the developer. To assess the benefits of such a solution, you should first calculate the turnkey estimate. This will help plan future expenses and find out whether there is enough savings for construction in the family budget. In addition, a detailed listing of materials gives an objective picture of the upcoming construction and suggests ways to save money without damaging the house.

Estimates are drawn up based on the house design. As an example for independent calculation of materials, consider a small building made of foam blocks on a strip foundation, consisting of three rooms, a kitchen and a terrace.

Estimate for the foundation

Since foam concrete is a lightweight material, screw piles can be used when constructing a bathhouse, summer kitchen or small cottage. According to experts, for building a house of 1-2 floors, a strip foundation is more suitable. It can be monolithic or prefabricated, recessed or shallow. Such a foundation for a house looks quite labor-intensive and expensive, but it has a big advantage. A strip foundation makes it possible to lay a basement or cellar under a residential building made of foam block.

A monolithic base, which is difficult to manufacture and reliable in operation, is well suited for the sample. The estimate for construction work will contain all the costs of its installation.

1. For an area with non-heaving soil, we select a shallow foundation 0.6 m deep. The trench needs to be dug 20 cm deeper to make a sand cushion.

For blocks measuring 600×300×200 mm, we set the width of the base to 0.5 m. The foundation for the house will be poured from the outside into the formwork, so its final height is 0.6+0.4=1.0 m.

2. Determine the length of the tape:

• (8×2)+(6×2) = 36 m, external walls;
• 8+6=14 m, internal partitions;
• 4+(1.3×2) = 6.6 m, terrace.

The total length is 48.6 running meters.

3. We calculate the volume of concrete required to pour a monolithic foundation: 48.6 (length of the tape) × 1.0 (height of the base) × 0.5 (width of the base) = 24.3 m 3.

4. In the construction estimate, we list the components necessary for mixing it yourself (if desired, you can order a ready-made, factory-made solution). Their quantity is determined based on the concrete grade M300. For 1 m 3 of mixture you will need:

• 385 kg of cement M400;
• 1080 kg gravel/crushed stone;
• 705 kg of coarse sand;
• 200-220 liters of water.

To find out how much of each material is required, we multiply the standard filling parameters by the filling volume:

• 385×24.3= 9.367 t cement;
• 1080×24.3= 26.244 tons of crushed stone;
• 705×247.3= 17.132 t sand;
• 540 l water (depending on the moisture content of the components).

5. We calculate the amount of sand for filling under the foundation of a house made of foam blocks:

48.6 (tape length) × 0.5 (width) × 0.2 (pillow thickness) = 4.86 m 3. We round the result to 5 and in total we get 17.132 + 5 = 22.132 tons of sand.

6. When building a monolithic foundation, reinforcement is always required. For our sample, we select a frame from two longitudinal rows, 2 rods each with a diameter of 12 mm. For transverse rows, reinforcement with a cross section of 10 mm will be required. With a jumper pitch of 0.5 m, the cross section of the frame is 30 × 0.65 m, the length of the rods is 0.35 m (horizontal) and 0.7 m (vertical). In total, for one structure (ring) you will need 0.35 × 2 + 0.7 × 2 = 2.1 m. In addition, for the joints on the jumpers you need to provide tires 3 × 4 = 12 pcs. 1 m each. Total 12 meters or 2 rods 6 m each.

7. We determine the total amount of reinforcement for the estimate for the construction of a house made of foam concrete: 48.6 × 4 + 12 = 206.4 m or 35 rods of 6 m each with a diameter of 12 mm.

8. Calculate the number of rings for jumpers: 48.6/0.5+1=98 sets or 35 rods of 6 m each.

9. To knit the reinforcement, use soft steel wire at the rate of 0.5 m for each connection. For jumpers you will need 98 × 4 = 392 pcs, for tires 12 × 4 = 48 pcs, a total of 440 ties × 0.5 m = 220 meters.

Estimate for foam concrete blocks for building a box

In the 6x8 house project, we plan to lay load-bearing walls in half a block. For internal partitions, a quarter of a stone is enough.

• 0.06 m – area of ​​the spoon or side of the foam block (200×300=60000 mm);
• 0.18 m – area of ​​the bed or base of the block (300×600=180000 mm).

1. In a house made of foam blocks, choose a wall height of 2.8 m. It will require 14 elements in half a block. Taking into account the seam joints (14 pieces, 0.5 cm each), we get 2.87 m. In fact, the height of the walls inside the room will be 2.6-2.7 m (reduced due to the ceiling and screed).

(8+7.3+8+6+4+1.3)×2.8 m=96.88 m2 – area of ​​load-bearing walls.

For construction you will need: 96.88/0.06 (S spoon) = 1615 pieces of half-stone foam blocks.

2. Determine the area of ​​the internal partitions: (8+3+3)×2.8m=39.2 m2. For their construction, foam blocks of a quarter of an element are required: 39.2/0.18 (S bed) = 218 pieces.

3. In total, in the construction estimate we indicate the following number of foam concrete blocks: 1615+218=1833 pieces.

4. Find out the volume of dry glue for seams in load-bearing foam block walls. We have 14 horizontal (2.8/0.2=14) and 58 vertical (34.6/0.6=57.6 m) connections with a thickness of 0.005 m.

• The total length of horizontal seams: 34.6 × 14 = 484.4 m, the amount of glue for it: 484.4 × 0.3 × 0.005 = 0.7266 m 3.
• The length of the vertical seams is 58 × 2.87 = 166.64 m, respectively, the glue required is 166.64 × 0.3 × 0.005 = 0.24969 m 3.

The total consumption is 0.7266 + 0.2499 = 0.9765 m 3 or 1000 kg.

5. We calculate the glue for the construction of internal partitions with a total length of 14 m. We have 10 horizontal (2.8/0.3=9.3) and 24 vertical (14/0.6=23.4) seams.

Total length of connections: (14×10)+(24×2.8)=207.2 m.

Volume of adhesive for interior walls: 207.2×0.2×0.005=0.2072 m 3 or 270 kg.

6. Total consumption of dry adhesive solution for a house made of foam blocks: 1000+270=1270 kg or 51 bags of 25 kg each.

How to save money on building a house made of foam concrete?

First of all, the correct choice of dimensions of foam concrete blocks will help reduce the budget. In cold regions, the main task of construction is to maintain heat in the house. Foam blocks 600×300×200 mm are best suited for these purposes. They are convenient to lay in any way, varying the thickness of the box at home to the desired size. The number of blocks will always be the minimum possible and without unnecessary costs.

To reduce the construction estimate for the cost of foam blocks and other materials, it is better to contact the manufacturer directly. Prices for wholesale quantities can be reduced by 5-15%. You should not save money by buying cheap foam concrete of dubious quality for construction. The additional cost of correcting uneven walls in the house will cover the difference and may even exceed the estimate.

The price of ready-made factory-produced concrete looks more expensive than homemade mortar for building a house. But saving on manual kneading can result in large losses of working time and unnecessary labor costs.

When calculating the approximate cost of building a house made of foam concrete, you always need to add more bulk materials. When unloading, sand, crushed stone or gravel usually crumbles and remains on the ground. Additional procurement and transportation increase the cost of the entire construction.

When choosing a mixture for laying blocks, it is advisable to give preference to special-purpose adhesives. Their price is certainly higher than cement mortar. But the consumption is an order of magnitude less. In addition, foam concrete masonry with glue retains heat much better.

When building a house from foam blocks with brick cladding, you can make calculations easier by using an on-line electronic calculator. When ordering an estimate for a turnkey house made of foam blocks, it is advisable to contact several contractors at once.
