Calculation of the amount of material for construction. How to calculate building materials Calculation of building materials for construction

Select total area

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

The area of balconies, loggias, porches, terraces and verandas is calculated with reduction factors from 0.3 to 1. The area of the attic is calculated up to vertical walls 1.5 m high, with a roof slope of 30 degrees. Below 1.5 to 0.9 m with a coefficient of 0.7. Below 0.9 m is considered a blind zone.

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

Foundation

Choose a 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 at the construction site and the selected design solutions for the future home.

The foundations we use with their design features ensure load-bearing capacity for any technology of walls, ceilings, roofs and facades we offer. However, weak soils or high groundwater levels may require adjustments to the type or design features of the foundation.

Select walls

1. Aerated concrete blocks
Aerated concrete and gas silicate blocks (not to be confused with foam concrete) are manufactured in a factory with strength gained in autoclave ovens. The blocks have an ideal geometry, which allows them to be laid on thin-seam glue with the absence of cold bridges. Aerated concrete blocks with a density of 400 and 500 kg/m3 allow you to build houses of up to 3 full floors without the use of reinforcing monolithic frames. A block thickness of 400 mm is sufficient for construction in the Moscow region using modern heating technology.
2. Large format ceramic blocks
Large-format ceramic blocks (warm ceramics) replaced piece solid bricks. Sawdust is added to the clay and when fired, it burns out leaving small closed pores, due to which the blocks have very good thermal performance indicators. 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. A thickness of 440 mm is sufficient for the Moscow region.
3. Monolithic (fixed formwork Plastbau)
Swiss Plastbau technology is a monolithic construction technology using permanent formwork made of expanded polystyrene. Wall panels are completely manufactured in the factory, including the reinforcement frame, and delivered to the site cut to fit a specific house project. Factory production allows you to obtain the ideal geometry of wall panels, which only need to be mounted and concrete added. The outer layer of insulation is 100 mm, and the inner layer is 50 mm. Such insulation is not only sufficient, but also exceeds the requirements for the Moscow region, i.e. This is already an energy efficient technology.
4. Monolithic (permanent Velox formwork)
The Austrian Velox technology is a monolithic construction technology using permanent formwork made from chip-cement slabs. The slabs are manufactured in a factory in standard sizes 500x2000x35 mm; the outer layer uses 150 mm thick polystyrene foam insulation, which exceeds modern heating engineering requirements for the Moscow region. The slabs are easily installed 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.
5. Monolithic (fixed formwork Durisol)
The Austrian Durisol technology is a monolithic construction technology using permanent formwork made from wood-chip cement blocks. The blocks are manufactured in a factory; the external blocks use 150 mm thick polystyrene foam insulation, which exceeds modern heating engineering requirements for the Moscow region. The blocks are easily installed 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 concrete multi-slotted blocks around the perimeter of all load-bearing walls of the house. Non-load-bearing partitions made of gypsum tongue-and-groove slabs.

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

Of course, the house consists not only of walls, but the customer’s choice is primarily based on their choice.

All wall technologies we use comply with current heating engineering standards in accordance with SNiP for the Moscow region. There are also technologies for increased energy saving, mainly using permanent formwork.

And of course, each technology provides sufficient load-bearing capacity to build a house up to 3 floors inclusive.

Floors

Select floors

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

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

All types of floors we use provide sufficient load-bearing capacity, fire resistance and sound insulation.

Select roofing

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

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

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

Standard equipment "warm circuit"

Select facade

The facade is the first thing that any person pays attention to when looking at a house. One glance is enough to tell whether he likes the house or not.

The choice of facade finishing 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 provide protection for load-bearing structures from the effects of weather conditions.

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

Select windows

Windows are an important component of a country house. Natural insolation of the premises occurs through them.

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

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

Today, the construction of houses made of 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 made of foam blocks.

We will focus on this issue in this article.

Why foam block

First of all, let us remind you: do not confuse foam concrete with aerated concrete. One of the articles on our website discusses in detail the fundamental differences between these two materials. It is worth noting that the price of foam concrete is more favorable.

What he really is

A foam block is a small “block” made by mixing a concrete mixture with special foaming components. It is the foam that forms cavities in the concrete, which reduce its weight and increase its thermal insulation 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 lazy and build everything yourself, then the savings will exceed even your wildest expectations.

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

Advantages of the material

No additives that negatively affect human health are used in production, 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 has no equal in this regard.
The structure of the material itself 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 point 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 principle of laying 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 unnecessary trouble, because the layer of plaster does not have to be thick.
Foam concrete has excellent fire resistance. At high temperatures, the material does not crumble or crack and protects the reinforcement from heating. In the event of force majeure, such a house will not let you down.

Disadvantages of the material

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

Low weight with a large volume, of course, leads to a loss of strength. For this reason, foam block has not received and will not receive widespread use in multi-story 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 correctness of the masonry. If the solution layer exceeds 3-4 mm, then you risk losing both heat and sound insulating properties.

Let's move on 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 clarifying the stages of construction. After all, only by analyzing the entire process in parts can you take into account every detail.

Count

The calculation of foam blocks for building a house should be based on the area of the 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 the walls.

The full cost calculation for building a house made of foam blocks is as follows:

Let us immediately stipulate that our sample has a width of 8 m, a length of 10 m and a height of 3 m. Main and external walls are taken into account.
the cost of the roof, foundation and other work can be calculated using separate calculators on our website.
So, let’s calculate the perimeter of the building: 10*2+7.4*2=34.8 m (rounded to 35). A reasonable question arises: how much is 7.4 meters and not 8? The answer is simple: you stacked 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 the walls: 35*3=105 sq.m. Everything is clear here: perimeter multiplied by 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. 95 sq.m. left.
We find out the area of the foam block: 0.6*0.2=0.12 sq.m. It turns out that for 1 sq.m. accounts for 1/0.12 = 8.3 foam blocks.
So, we complete the calculation: 95 * 8.3 = 788.5 blocks are needed for the external walls.
It would seem that the calculation of materials for building a house made of foam blocks is complete, but no! We did not take into account the main wall.
Its length in our sample will be 9.4 meters. Multiply by height - we get an area of 28.2 square meters. Again, let’s assume that the windows and doors will take up 5 square meters. We get 23.2 sq.m. 23.2*8.3= 192.5 blocks.
We add up the resulting numbers: 788.5+192.5=981 blocks are needed for such a construction.

So, calculations for 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 3,000 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 these instructions are approximate and accurate calculations are only possible with a thorough knowledge of the project.

Construction progress

First of all, the foundation for the house is built from foam blocks. Since the foam block is lightweight, there is no need to spend money on an expensive monolithic foundation. An excellent replacement for it can be a belt one, which uses much less crushed stone, sand, concrete, and even uses reinforcement of a smaller diameter.

After the base has gained the required strength, it is time for laying. It starts with laying roofing felt between the base and the first row as waterproofing.
The corner blocks are laid first. Moreover, special attention is paid to the corner, which according to the plan will be the highest. The corner is leveled and proceed to the next one.
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 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 unevenness immediately with a plane.

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

Electrical wiring is also laid in grooves according to the same principle, but the laying pattern depends on the specific project.

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

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

For interior decoration, drywall, boards and textured plaster are excellent options. It’s even easier on the outside - use siding or finishing bricks.

Let's sum it up

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

To further understand the process of constructing a foam block building, pay attention to the video in this article. See you again on the pages of our website.

In order to avoid unreasonable cost overruns in future construction, as well as to avoid a shortage of materials leading to a decrease in the strength of structures, it is recommended to use professional special estimates. The Osnova company offers site visitors and potential customers to use an online calculator to calculate the construction of a house, as well as professional services of estimators.

Features of the construction calculator

The calculator on the page of our website allows you to perform the following operations:

Calculation of materials for building a house. The main ones are taken into account (foundation, walls, roofing). Calculation of the cost of installing communication networks (water supply, sewerage, ventilation, etc.), as well as basic interior and facade finishing.
Calculation of the required dimensional parameters.
Coordination of raw material characteristics with SNiP parameters.

If desired, the customer will be able to contact the company’s specialists in St. Petersburg to order a full estimate for turnkey construction, where the materials desired for use in finishing or construction will be calculated. We work throughout the Leningrad region.

Methods for calculating estimates - determining construction volume

The methods for determining the full estimate are as follows:

Measuring the project area. Calculations are carried out according to an approved package of documents, which includes drawings and sketches of the future structure.
Calculations based on the area of the site. A visit by a specialist to the site of future development will allow you to determine the approximate parameters of the property.

The error of the result is up to 15–20%. The methods are suitable for multi-story or commercial construction, where it is difficult to take into account all the nuances. For the construction of a private house, a method for determining the construction volume is suitable. This method of calculation is considered by experts to be more objective and complete and consists of an expert assessment of the cost of construction for each segment. Not only the cost of building materials is taken into account, but also the price of work

How to use the calculator

The Osnova online service will help you calculate an estimate for building a house yourself and free of charge. However, it should be understood that without experience and understanding of construction processes, the result will still have an error. The sample given by the site is only suitable for preliminary calculations to assess your own financial capabilities. So:

In the “Walls” column of the calculator, you need to select the desired construction materials - aerated concrete, frame or brick. The same applies to roofing and finishing materials.
They do the same with other columns - floors, engineering, finishing, double-glazed windows, etc.
The types of technologies used are selected.

If the desired materials and technologies for building a cottage are not on the list, it is recommended that you contact the consultants directly and order a full estimate for construction. It takes into account any “little things”.

The nuances of using an online calculator

Of course, it will not be possible to calculate the project thoroughly. Any virtual calculator has errors. In addition, during the construction process, nuances may arise - the customer will make adjustments, or other factors beyond the control of the parties will arise. However, they must be reduced to a minimum in order to ultimately obtain the optimal result.

Why is it worth ordering a construction estimate from us?

The advantages of working with the Osnova company are obvious:

Affordable cost of projects for housing construction, as well as related facilities. Prices are favorable for both private and corporate developers.
Opportunity to find cost-effective solutions. Our specialists are competent in any construction issues and will suggest the best option for materials and technologies, according to the customer’s budget.
In addition to detailed projection and calculation of load-bearing structures, the company offers construction services.
Convenient receipt of documented results - the customer will be able to receive the result by email and subsequently print it for ease of use.

Our specialists have more than 10 years of experience. Strict adherence to deadlines and excellent results are favorable conditions for working with numerous clients.

In the modern construction industry, more and more innovations are appearing that are designed to make the work of architects and their clients much easier. In this article we will talk about such a tool as construction programs, which allow you to determine with the necessary accuracy the main costs, construction time and many other parameters.

Any Internet user can download construction programs for free. Most modern applications are developed and uploaded to the network by popular construction companies, which thus conduct a competent advertising campaign for their services on 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 independently, without the help of an experienced designer or architect, create a 3D model of their dream home. A secondary program for construction calculations will help you 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 construction calculation programs from the “hacked” class have an unlimited validity period, but a simplified and reduced set of tools. Because of this, many difficulties can arise not only with demonstrating the model, but also with its addition or re-development.

Before you turn your attention to free construction programs, you should note that professional applications for modeling and estimating a home 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.

This section discusses the main parameters that construction design programs should have.

Construction drawing program

A standard program for construction drawing must comply with all 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. Using this tool, the user can create a basic drawing of the house with pinpoint accuracy, as well as draw up a detailed plan of the interior. Basic skills in drawing and architecture are required to use this application. Thanks to the simple interface, the user will quickly get used to the presented professional environment.

House drawing in Home Plan Pro program

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 designer, where each element is assigned a place in the appropriate category. Also, when constructing certain structures, any application should provide the user with the opportunity to see how a real model will behave under different weather conditions.

The very first thing a home owner thinks about is how much the new building will cost, whether there will be enough savings to complete the plan or whether everything will have to be put off until better times.

There are, indeed, a lot of fears here, and even more fears that are not confirmed by anything. You can calculate the budget for building a house in advance, slowly and very thoroughly.

In this case, everything will be taken into account. Unless it will be impossible to count an accidental lightning strike on a construction site or another force majeure event. Although, with rational planning, even such things can be foreseen in advance and should not cause confusion in the work on the construction site. We will try to give the answer to how to simply and correctly calculate the price of implementing a planned house project in our publication.

House price calculation

The easiest way to calculate the price of a future home is to, having in hand a project or at least a sketch of the future structure, contact the specialists of the construction company InnovaStroy. Specialists will offer you a free consultation on questions regarding building a house. The price of the house is calculated by the company's specialists based on your needs and capabilities. The calculation of the project itself and the design of the house can also be carried out by the company’s specialists.

You can take a different route - look at the company’s website for ready-made house designs and ask about current prices according to finished house projects In any case, it is better to directly contact a specialist who can clearly answer the question that concerns you. In particular, he can expertly calculate how much design and construction, decoration, home design or geological surveys will cost. If you want to review these calculations and conduct your own analysis of potential construction costs, then listen to our advice.

The calculator is great, but... Nowadays it is quite fashionable to calculate the cost of construction using an online construction calculator. Sometimes such systems are well designed graphically and present the essence of the issue in detail. However, all these are too rough calculations that have a large level of error, sometimes reaching 50% or more. The reason is obvious - construction calculations cannot be carried out according to general ideas and by substituting visually suitable construction elements into the general estimate. This is too rough a calculation. Therefore, such calculators, despite their apparent professionalism, very often sin with calculations that are too approximate and far from reality.

There is one advantage in these methods of finding out the price of a future home - you can at least see, as they say, the order of the numbers. But nothing more, because in addition to the price of building materials, you also need to find out the cost of their delivery, loading and unloading, installation, and post-installation processing. The cost of transport services alone can range from 5% to 20%. There are many other factors that are often not taken into account in such calculations. Therefore, the longest and most difficult, but perhaps the most correct option is still working with a finished project. Part of any complete construction project for a house is its estimate, which details the price of all materials, as well as the cost of services for their installation and putting the house into operation. Let's take a closer look at how to correctly calculate the cost of construction work.

Foundation price

One of the most expensive jobs in building a house is building the foundation. The cost of installing it depends on the following factors:

climatic conditions of the area;
house structure - frame, solid brick or aerated concrete blocks;
soil type, soil properties;
selected type of foundation.

When you have this data in your hands, then you can accurately calculate the amount of materials needed for construction and their range. Here are a few indicators that will give you a general idea of how much materials you need to spend on foundation work:

with a brick foundation wall thickness of 510 mm, the mass of the wall will be 920 kilograms;
if it is a hollow brick with a wall thickness of 380 mm, then the weight of the wall will be 450 kg;
lightweight concrete panels with a thickness of 250 to 400 mm will weigh 230-550 kg.

On average, both work and materials for building a foundation of various options will cost 20-30% of the cost of building a house, if you do not take into account the internal design in the cost of the house. You can reduce the cost of building a foundation by arranging a foundation on piles. However, a lightweight pile foundation must be for a small house, otherwise you will need to use special equipment. Meanwhile, a pile foundation may be cheaper due to the fact that there is no need to remove a lot of soil, mix and pour concrete formwork, or build a brick foundation wall. Taking into account such a reduction in the cost of a house project, the price of foundation work may even reach minus 40-50%.

If you are building a regular concrete strip foundation, then you should take into account that for 1 cubic meter of masonry of such a foundation, more than 1 cubic meter of rubble stone or brick will be spent. meters, and cement mortar - 0.4 cubic meters. meters. The construction of pillar foundations for lighter houses with a simple design or built from light wall materials will require a consumption rate of stone or brick at the level of 1-1.2 cubic meters. m per 1 cubic. m of masonry. In this case, no more than 0.27 cubic meters of cement-lime mortar is needed. m. Separately, you should take into account the costs of installing the base and waterproofing.

Walls are an important part of the house

Calculating the price of construction cannot do without calculating the cost of erecting walls. Depending on the materials that can be used in construction - wood, brick, concrete - the price of construction also changes.

There are several practical examples of calculating the price of wall construction:

a house made of profiled timber should be designed so that for one degree of winter cold there is 0.8 cm of timber;
if the house is built from solid brick, then with an average air temperature in winter not lower than minus 30 degrees Celsius, the wall thickness should be at least 65 cm;
the construction of walls from different materials requires different calculation data, therefore, when calculating wall structures, the height and length of the elements that make up the wall should be taken into account.

There are norms for the consumption of bricks during the construction of walls, for example, when laying a wall with a thickness of 250 mm. If you take 1 cubic meter of masonry into account, then it will require at least 400 solid ceramic bricks, 0.2 cubic meters. m of mortar. Based on these standards, it is possible to calculate the need for brick and cement, sand, and other components of masonry.

How much does a roof structure cost?

Calculation of the necessary building materials for the roof begins with the exact figure of the roof slope. It can range from 5 to 60 degrees. Depending on this, the consumption of building materials will be normalized.

For this, a simple formula is used - half the span width of the house is multiplied by the relative value. For example, with a slope of 25 degrees and a house width of 8 m, the calculation will be as follows: 4 m multiplied by 0.47 = 1.88 m - by this height (1.88 m) the rafters must rise. When constructing a roof, an overhang of rafters is usually made, which is from 0.5 m. Roofing materials are taken into account by estimating the roof area. Each material has its own margin of accuracy and joining. For slate roofing it is small, but the need to calculate the length of each element should be taken into account.

If the length of the roof or its width turns out to be greater than required, you will have to cut off half or most of the slate slab and thus, the consumption of this roofing material will increase regardless of the roof area. The situation is similar with metal profile structures for roofing work. It is easier to calculate tiled roofs or roofs made of soft tiles and other materials that can be cut without sections and supplied for construction. However, it should also be taken into account that soft roofing materials can be supplied in roll bags of a certain length, which may also entail additional costs compared to the calculated ones.

Engineering and Design

After the “box” is constructed, construction of utilities should begin. Often, interior decoration of walls and rooms is also done together with them.

Typically, interior, engineering and finishing works include:

sewerage and water supply;
construction of a heating system, including installation of a “warm floor” system;
wiring of electrical networks, installation of engineering electrical appliances. These could be, for example, split air conditioning and ventilation systems;
construction of any partitions or design objects
installation of internal fences, fastenings, plastering and interior decoration, including draperies, stretching, wallpapering.

Elements of landscape design should also be included in design decisions. Is it possible or not to count all the necessary nails, screws, sockets and other little things? In principle it is possible, however, this is hardly the developer’s primary task. There is a simple recommendation on how to check the need to install one or another electrical system or plumbing facility.

Check the data with the project, calculate the average number of the same sockets or taps. Take into account only large components, since they will make up the largest part of the construction cost. To the estimate for all these materials, you can safely add 50% of their cost, and in some cases, for example, when installing a specific bathtub or equipping an indoor pool with a self-cleaning system, then even 100%. This will be a rough, but quite close to reality, estimated cost amount construction work.

It should be noted that the cost of unique work, for example the construction of a decorative fountain, can be significantly more expensive than traditional bricklaying, although in fact they are the same thing. The fact is that such specific types of work are usually undertaken by narrow specialists, therefore the price of such work may be higher and this is justified.

Three myths of calculating construction costs

There are some important tips that will help you avoid unnecessary risks when calculating the cost of building a house.

To reduce the cost of construction as much as possible, since savings or cash are not always in the right amount, some developers make three mistakes that can, instead of saving money, cost them significant unforeseen expenses. These are the typical mistakes:

Hiring unprofessional builders who can reduce the cost estimate by up to 50-60%. As it turns out later, laying certain building materials requires experience, and unprofessional pouring of the foundation or starting to lay walls will lead to more disastrous consequences - deformation of walls or ceilings, poor foundation stability. In addition, the consumption of building materials will be much higher, since non-professionals simply do not know how to lay mortar correctly and on time, rationally lay bricks or do roofing work. There are especially many questions regarding internal and engineering work. As a result, all actions aimed at supposed “savings” will result in an even larger budget.
The price of work without a project or a detailed design is cheaper, and construction work without an estimate, which can “save” 10-15% of the construction cost, is better than the full development of project documentation.

We have already explained what unprofessional work with building materials can result in. Approximately the same will happen when you do not have complete documentation on hand. The finished house project with all its necessary components also includes detailed plans, including utility lines, placement of certain devices and components. The estimate can be clarified and drawn up specifically for the house, for certain materials and models of windows, walls, drywall, nails, screws, taps and similar construction details.

On the one hand, this may seem like unnecessary and overwhelming detail, and you really may not require such overly accurate calculations. On the other hand, if you are building a large house, then such details can ultimately make up a significant part of the construction budget. In any case, the presence of estimate documentation disciplines both the developer and the builder, since there is a document and specific technical instructions for construction.

You can find out the price of building a house from your friends and use it as a guide when making decisions.

This is not entirely the right decision. If the start of construction of a house follows all the rules and in this case:

geodetic work is carried out;
the house project is drawn up by a competent professional designer;
all conditions for the placement of the house, the need or, conversely, the absence of the need to erect a heavy, powerful foundation, the construction of a certain type of walls or roof, are established based on the results of research;
The calculation of materials is done according to standards, and not by “eyeball”, then the results of calculating the construction price may differ significantly.

The price of a house is individual, just like a person’s character. In one area with a difference of hundreds of meters, the composition of the soil may change. The architectural and planning solution may also change. The simplest thing that can significantly increase or decrease the cost of a house is the presence or absence of utilities, including electricity and water. Therefore, assessing the price of a building based on friendly advice may turn out to be very inaccurate information.

How to count correctly

If you decide to correctly calculate the price of a house, then you should take into account many factors. Independently calculating the construction price can lead to gross miscalculations. And the point is not only that the developer does not always have complete information about the price of materials or the cost of construction work. The fact is that there are many other circumstances that influence the price of construction:

seasonality of work;
payment and its form;
materials recommended for construction;
discounts offered by the order executor;
rational construction methods.

We have named only a few additional, but significantly influencing the price of construction, factors. For example, if you decide to finish building a house in winter, then the price of construction will increase, since you will need to pay for more expensive labor and the necessary additives to the solutions, the use of frost-resistant binding materials, which are not used in the spring-summer season.

If we summarize our research, we can come to the obvious conclusion - construction and its calculations are not easy and require significant special knowledge or extensive construction experience. Correct calculation will save your money and time, and most importantly, it will give you confidence that you will be able to complete the construction of your house on time and without difficulties.
