Estimate for the construction of a house from blocks sample. How to correctly draw up an estimate for the construction of a house - practical advice

Anyone who wants to build a house or make repairs in 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, it will be possible to find out how much money is needed. And also decide whether to involve builders or do everything yourself. Not everyone knows how to make an estimate, what positions 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 the costs of the upcoming construction or repair. This can be easily done on your own, without having specially designed programs.

How to make an estimate on your own? It is enough to have the Excel program on your computer. It is necessary to carry out the calculation of funds and materials very carefully in order to avoid errors and exceeding the planned costs. It should display everything to the smallest detail.

Common Mistakes

When drawing up estimates, many make mistakes, which then come out and provoke unforeseen waste:

• Calculations are carried out without a preliminary inspection of the object on which the work will be performed.
• Not mortgaged additional expenses that may arise under force majeure circumstances.
• Doesn't count complete list works and materials.

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

What is needed for a competent budgeting

Before drawing up an estimated estimate for construction or repair, first of all, it is necessary to inspect the object. After that, a list of all ongoing work should be compiled.

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

The main items of the estimate

Any construction estimate consists of three main positions:

• materials;
• Job;
• transport.

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

In the first position indicate the 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 find on the Internet on sites specializing in the sale of building materials.

The second position includes a listing 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 paste over the room with new wallpaper. For this, it will be necessary to preparatory work: remove the old coating, clean the walls, prime them. Estimated cost necessary work can be found in ads.

The position "transport" includes: delivery of materials, unloading, removal and removal of construction debris, indicating each item on a separate line. Information about the cost of these services is provided in the price lists of firms.

Drawing up an estimate for the repair of an apartment

How to draw up a budget in order to carefully plan the event repair work in the apartment, finish them in short time at minimal cost? First you need to decide what kind of repair you will do: cosmetic or major. It depends on the amount of materials needed and the amount of work. If you decide to spend overhaul, then the estimate should be divided into two parts:

• repair and finishing works;
• draft 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 ​​walls, floors, window slopes, compile a list of finishing and draft materials, determine the cost and scope of work for each room separately.

Example

Here is an example of how to make an estimate for repairs. Prices and consumption of materials are fictitious.

Repair and finishing works:

Consumables and finishing materials:

Transport:

To get the preliminary results of the cost of repairing an apartment, you need to add up the total amounts from each column.

18819 + 7870 + 4000 = 30689 (rubles)

You should be aware that the final costs always come out more by 10-15%.

30689 + 15% = 35292.35 (rubles)

The principle of calculating construction costs is no different from estimates for repairs. Only production cycles and materials will change. How to make an estimate for construction with minimal costs? To do this, you need to carefully plan all the work, clarify what materials will be needed, find out the prices.

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

Today after update budget and regulatory framework- GESN, TER and FER, it will not be difficult to make an estimate for the construction of a house and calculate the exact cost of the work.

Are you a private developer - building a house for yourself, or major investor- build a house for a thousand apartments - to build a house without an estimate, as they say, "is more expensive for yourself." After all, the estimate includes all the costs necessary to build a house.

In this article, we will consider the main stages of drawing up an estimate for the construction of a private house and you can download it.

In our example, we will not take into account all the possible complicating factors of construction, we will assume that the cost estimate takes place under standard construction conditions. We take the area of ​​\u200b\u200bthe house 100 m 2 (10 * 10).

Of course, if you are not going to put up a tent or temporary hut, then you cannot do without taking into account the cost of earthworks in the estimate. Indeed, for the construction of the foundation, it is required, in the truest sense of the word, to "prepare the ground."

We will excavate the soil for the foundation using a mechanized method. The volume of the pit is 100 m 3 (10 * 10 * 1), where 10 is the length of the side of the house, and 1 is the depth of the pit. To calculate the cost of these works, we take the price:

FER01-01-013-03 Excavation with loading onto dump trucks by excavators with a bucket with a capacity of: 1 (1-1.2) m 3, soil group 3 - 100 m 3

Pay attention to "soil group 3". In the technical part of the collection FER01 Excavation, all groups of soils are indicated, in our case these are "gravelly sands" more common in the middle part of Russia. By the way, it is not in vain that we dig a pit 1 m deep, because the depth of soil freezing in the same regions is 900 mm.

Foundation

We take as a basis a tape monolithic reinforced concrete foundation. We design the foundation for external walls, i.e. along the perimeter of the house, as well as under the load-bearing walls - conditionally, these are two walls that intersect in the center of the house. Let's calculate the volume: 10 * 6 * 0.5 = 24 m 3, where 10 m is the length of the outer and internal walls, 6 m - the number of load-bearing walls (4 - along the perimeter of the house and 2 - intersecting in the house), and 0.5 m is the thickness of the foundation. Now we will select a price for our estimate for the construction of a house:

FER06-01-001-22 Device strip foundations: reinforced concrete with a width along the top up to 1000 mm - 30 m 3

columns

The most optimal and common option is the device reinforced concrete columns at the intersections of load-bearing walls. Firstly, the columns add strength to the structure, in our case, to the house, and secondly, by building cottage you can fearlessly rebuild it into a two-story building.

Let's calculate the volume of our columns: 9 * 3.5 * 0.4 * 0.4 \u003d 5.04 m 3, where 9 pcs. - the number of columns (8 along the perimeter and 1 in the center), 3.5 m is the height of the column, and 0.4 m is the length and width of the column. For an estimate for the construction of our house, we take a price:

FER06-01-026-15 Installation of reinforced concrete columns in wooden formwork with steel cores (rigid reinforcement) with a perimeter: up to 2 m - 5.04 m 3

load-bearing walls

Before considering the amount of work on the installation of walls, we determine for ourselves that we will make all the load-bearing walls (remember we made the foundation for them) from a common cinder block (w19 * h19 * d39) and put it in two rows, i.e. the wall thickness will be 400 mm.

With all known parameters (the length of the walls is equal to the length of the foundation, the height of the walls is equal to the height of the columns, and the thickness is equal to the thickness of the masonry), we get the masonry volume 60 * 3.5 * 0.4 = 84 m 3.

We continue to draw up our estimate for the construction of a house and take the following price for laying load-bearing walls:

FER08-03-002-01 Masonry of walls made of lightweight concrete stones without cladding: with a floor height of up to 4 m - 84m 3

beams

For structural rigidity, our columns must be tied at the top with a beam. The installation of beams could be done simultaneously with the columns or a stage after the columns, but then there would be difficulties with the installation of formwork under them. And so, at this stage, the walls play the role of the lower part of the formwork, which greatly simplifies the work of knitting reinforcement and laying concrete mix.

Let's calculate the amount of work. The length of the beams is equal to the length of the foundation, and the section of the beam is equal to the section of the columns - 400 * 400 mm. From here we get 10.6 m 3. For an estimate for the construction of a house, choose a price:

FER06-01-034-02 Installation of beams for floors, crane and strapping at a height from the support platform: up to 6 m with a height of beams up to 500 mm - 10.6 m 3

By the way, it was not in vain that we postponed the process of installing beams. We combine the knitting of the reinforcement cage of the beams and pouring with concrete with the knitting of the reinforcement cage of the floor and its concreting.

The ceiling, in addition to being the ceiling of the first floor in our house, can also, in the future, serve as the floor of the attic or second floor. Therefore, we will make it reinforced concrete!

For our estimate for building a house, the volume is considered very simple - the area of ​​\u200b\u200bthe house is multiplied by the thickness of the floor - 100 * 0.16. Let's rate:

FER06-01-041-01 Installation of beamless floors with a thickness of up to 200 mm at a height from the support area up to 6 m - 16 m 3

Roof

At the first stage, we will add the device of rafters to the estimate at a price:

FER10-01-002-01 Installation of rafters - 5 m 3

On the second - we will cover our roof with galvanized iron. We add about 30% to the area of ​​the house and get the area of ​​​​our roof, taking into account overhangs and slopes. Let's take the following estimate:

FER12-01-007-09 Installation of galvanized steel roofs: with wall gutters - 130 m 2

Conclusion

Well, that's all - our house is ready! The author should not be reproached for not taking into account all aspects of this construction and budgeting, the task was simply to show how the estimate is compiled and the amount of work is calculated.

And, as promised at the beginning of the article...

The fact that any business must begin with calculations is known to every person. Get ready to paste wallpaper in the house - calculate what costs will be needed for wallpaper, glue, putty, painter's work. If you want to build a table with your own hands - calculate the cost of boards, screws, PVA glue.

When building a house, it is necessary to take into account all the construction stages and the costs of them. Such indicators are concentrated in the working draft in the section budget documentation.

How to make an estimate for the construction of a house without loss and revision?

About how to make an estimate for the construction of a house, it is known to estimators, foremen, other categories of engineers and builders. Ordinary people who are not associated with construction work, but who have started the construction of a dwelling, have some idea of ​​\u200b\u200bthis. Their desire is clear: they do not want to overpay extra amounts. If a person is persistent and purposeful, it will not be difficult for him to carry out the calculations himself. Sample estimates for the construction of a house are widely presented on the Internet.

Estimated documentation is prepared on the basis of calculations, which presents items with indicators:

• serial number;
• numbers of estimates and calculations;
• names of the construction stage;
• estimated cost, which consists of the cost of construction and installation works, the use of materials, other expenses;
• total estimated cost.

Estimated calculations signed by the compiler's management and the customer are considered money document, which is the basis for the actual performance of work, participation in the tender, etc.

When drawing up an estimate for the construction of a house, all important and secondary positions are taken into account. Sometimes it seems to the customer that the inclusion of a particular expense item is not necessary at all. But in the course of construction, unforeseen expenses unaccounted for in the documentation “loom”. The customer understands this and lays in the documentation 5-10% for unforeseen overhead costs. This may be funds aimed at obtaining permits from fire authorities, gas workers, electricians, water suppliers and other permitting authorities, or other types of expenses.

As you can see, it is not very difficult to make an approximate estimate for building a house if you know the consumption of materials, standard prices and current prices. The article also provides a sample estimate for a residential building made of gas blocks (see fig.).

Output

Each person can calculate the cost of construction. But experts do it more skillfully and competently. Sometimes they overestimate the amounts for individual items. In order to adjust the indicators, the owners themselves can perform the calculations or turn to the help of other organizations.

The most important stage in the design of any building or system is the preparation of cost estimates. The estimate allows the customer and the contractor to establish the contractual cost for the contract being concluded, optimally plan and analyze the entire complex construction works, distribute cash investments, and also carry out interim financial calculations.

The construction of any large facility, in which monetary investments are very large, must be carried out with the calculation of the cost of all materials, the performance of works and services, the price tag for renting and operating the equipment used. special equipment. That is why in construction industry special settlement documents are used - estimates, in which all the costs for the construction of a particular property are listed.

As an introduction, we present such a document. The focus of our attention is the estimate for the construction of a private house, a sample of which is presented below.

Before the construction of any house, an estimate for its construction is calculated, one copy of which is transferred to the customer. It describes in the most complete way where and for what purposes the funds allocated for construction will be spent.

Even when erecting a very small object on his garden plot, the customer has the right to demand an estimate for its construction. This article will describe and present samples of estimates for building a house from different materials.

The composition of the document and who can develop it

The estimate is usually based on project documentation object under construction. It signs a list of materials needed for construction, their cost, time for work and their labor costs. If during the construction process any special types of work arise, they are also included in the estimate as separate items with a price.

This type of document can be developed either by specialized budget organizations, or by the designers themselves, who, together with the calculation of the project, are able to calculate the cost of its construction. The customer, before work begins, has the right to view an approximate estimate for construction and estimate his financial capabilities. This is very convenient, because you can make adjustments to the documentation in order to use cheaper materials or reduce the size of the future building. How to make an estimate for the construction of a house? A sample will help you understand everything.

We manage ourselves

For an independent assessment of the cost of a future residential building or construction on your site, it is easiest to be guided standard samples and calculate the cost of materials and labor. The article presents several estimates for different buildings. It remains only to substitute your own length values, the types of materials used, their cost. For example, below are sample estimates for the construction of a residential building.

It is most convenient to make such calculations in electronic Excel tables. However, there is a difficulty here. All types of work must be presented in prices in one currency.

In what cases are several estimates made?

If the construction of the house was made on a turnkey basis, then it is enough for the customer to require only one document on the costs incurred. In the event that several contractors are hired to perform different works, and exactly the same number of estimates is made.

Any estimate is drawn up on a standard form, where all the work performed, their price and the cost of the materials used are signed. In order to understand this issue well, we present to your attention samples of estimates for the construction of a house from timber, foam blocks and frame type with a detailed description.

Estimate for the construction of a house from a bar. Preparatory stage

Before the main financial calculations, you need to pay attention to the layout of such a house. You should take into account the number of rooms in the project, the overall dimensions of the structure and how much in general square meters it will take. The next stage is the allocation of the main groups of expenses. There will be several:

• The cost of acquiring the main The main in a particular case will be timber. The total cost of this group of expenses will also depend on the type of wood, its cross section, and performance characteristics.
• The cost of other materials for building a house. This will include roofing, floor boards, various materials for sheathing the walls of the building.
• The cost of finishing materials. These are various paints, parquet, wallpaper with tiles.
• Foundation costs. This part of the structure should be singled out in a separate group and the amount of material and its cost with delivery, as well as payment for the work of contractors, should be calculated in it.
• Communication costs. This includes gasification, electricity, water supply and sewerage.

It is worth noting that the above cost calculations are almost the same as those that make up the construction estimate. wooden house(you can see a sample in the photo below).

Detailed analysis of available information

So, the initial stage has been completed, the main groups of expenses have been outlined in such a document as the estimate for the Sample will be given below, and we will consider the collected data. At this stage, it is necessary to allocate all the collected cost groups to the structural elements of the future home - the costs of the foundation, walls, roof and decoration.

Most importantly, when calculating, it is necessary to take into account the architectural features of the future building, the design direction, the format of the roof, the types and number of future communications, the need to use special equipment and the involvement of professional builders, as well as the cost of delivering materials to the construction site and removing construction debris.

Moreover, it is necessary to take into account the costs of conducting various examinations on the building site and the remuneration of designers.

Estimation calculation

For the correct calculation of investments in a house under construction from a bar, it is necessary to correctly determine the amount of materials, the cost of transport services and installation types of work.

When calculating the cost of materials, the following main parameters must be taken into account: type, price per unit, required quantity and total cost for the entire volume. A separate line to this amount is added to the costs of transport and the work of loaders.

The main material is timber. The first step is to calculate the number of bars needed to build a house. They are usually sold in cubic meters. And here it can be difficult to compare the number of cubes to the actual number of timber.

But it's not a problem. First you need to calculate the total perimeter of the structure by Then multiply the resulting value by its height. And the resulting product must be multiplied by the cross-sectional area of ​​\u200b\u200bthe beam. Thus, the total volume of material in cubic meters required for construction will be obtained.

This indicator is included in the estimate, having previously calculated it at the market price.

Calculation of costs for the foundation, roofing and finishing materials

First of all, you need to calculate the dimensions of the foundation, from which the volume will be clear required material. To do this, the perimeter of the base of the house is multiplied with the height and thickness of the future foundation. The result is volume data. It remains only to find out market value one cubic meter of concrete and multiply it by the resulting value.

Roofing materials are considered very easy. Taken from project documentation total area the roof of the house, the cost of one square meter of the required roof is monitored, then these data are multiplied.

The calculation of the cost of finishing is the most painstaking, since a variety of materials are used. It will be necessary to multiply the covered area of ​​\u200b\u200bthe wall by the cost of one square meter of each material separately.

So, in conclusion, you need to calculate all the costs and display the grand total. As you can see, a very important and informative document - an estimate for the Sample will help to carry out the entire procedure as quickly and without errors as possible.

Estimate for the construction of a frame house

Construction cost calculation frame house not much different from that for a house made of timber. The difference will be only in the material. First you need to determine the shape and size of the future structure. You also need to take into account the costs of the foundation, walls and roof, the cost of loading and good decision allocate a percentage Money for unexpected costs. These are the main points that should be included in such a document as an estimate for the construction of a frame house (see sample below).

foam block house

Before drawing up an estimate, you need to decide on the types of materials that will be used for construction. Blocks for the construction of houses are of three types - foam concrete, aerated concrete and expanded clay concrete. The best choice for construction according to operational characteristics there will be aerated concrete. Its price tag in the domestic market is not particularly high. If we consider a house with an area of ​​​​about three hundred square meters, then the total cost of aerated concrete will result in thirty thousand rubles per square. Recently, foam concrete has also become popular.

When calculating the estimate, the methods discussed above are used. A sample budget is shown below.

Required paragraphs of the document

Each construction estimate, regardless of the construction and material used, should contain the main points. This is, first of all, the cost of materials (both basic and finishing), which should contain any estimate for building a house. The sample given in the article shows that it should indicate the amount of costs for transport and loading operations, labor costs for a team of craftsmen, unforeseen expenses.

At the end of the calculations, the final figures are given. They are divided into amounts of direct costs, the main wages, use of equipment, cost of materials and labor costs, overhead costs and a planned allowance (profit of the developer company).

Sample estimates for the construction of a house from different materials were considered by us above. They are not very different from each other and have similar compilation methods.

Finally

In order to compose construction estimate, it is not necessary to involve specialists for this. You can manage on your own. To do this, you don’t need so much - it will be enough to have a calculator, a project on future home and monitoring of market tariffs for Construction Materials. Sample estimates for the construction of a house, given in the article, will also come in handy. Even in the absence of professional skills, it is possible to see an approximate picture of the total costs and significantly minimize them. If you have any doubts about the correctness of your own calculations, then you can contact the experts.

As you can see, there is nothing complicated in such a document as an estimate for the construction of a house (see the sample above). Good luck in compiling it!
