Projects of estimates for houses drawn up with his own hand. Estimates for the construction of a house and country cottages. The sequence of actions for self-budgeting

The need for self-preparation of an estimate can occur in several cases: during the construction of a private house, before carrying out renovation works etc. It often happens that a person, deciding to improve their living conditions, does not want to turn to professional estimates for expensive services, but needs an accurate and up-to-date estimate.

Also, the development of an estimate calculation may be required to determine the alternative costs of building a new or buying a finished home. Taking into account the current value of real estate, the option of building a new house is often considered along with the acquisition of "new building" and secondary housing, and at the same time, one can confidently speak about the advantages of one over the other only after economic analysis their full value.

If everything is more or less clear with real estate prices, then the task of calculating the funds necessary for the construction of a private house sometimes causes a lot of difficulties. For example, price fluctuations in the markets for building materials and services can seriously complicate the determination of the amount of capital investment required. Meanwhile, the results of initial flaws on the part of home owners and designers eventually turn into unfinished structures, the construction of which was stopped due to errors. construction plan, or due to inaccurate calculations of the required volumes Money.

Estimated calculation or estimate is one of the most important documents of any construction, as it contains a list of planned construction and installation works with the approximate volume and cost of materials and services. The amount based on the results of the estimate is compared with the prices for similar finished buildings, of course, taking into account the discount factor (inflation during the period of construction of the house). It is important to understand that the resulting cost of construction or repair, calculated according to the estimate, is directly determined by the quantitative parameters and characteristics of the premises obtained in the course of measuring and calculating the actual amount of work that will need to be estimated and then performed.

The sequence of actions for self-budgeting

To draw up a simple estimate based on current market prices, (but not prices from collections for the development of estimated calculations in HPES (state elementary estimate norms) or TEP (territorial unit rates)) you can proceed as follows:

1) First, you need to find or independently draw up an algorithmic sequence of works planned for the construction or repair of a house, necessarily broken down by the duration of their implementation, provided that technological breaks are observed, for example, for solidification of concrete floors, foundations, etc. You also need to decide what kind of work will most likely have to be transferred to construction organizations, and which of them can be carried out on their own. So, if some finishing work, such as wallpapering, painting surfaces or putty, is traditionally considered simple, then in order to complete the rest, most likely, you will have to turn to professional craftsmen.

2) The next step is to calculate the approximate volumes of building materials and structures, complex application which is determined by the technologies used in construction.

3) After that, you can call a couple of firms providing construction services and get the current price lists for building materials and construction work.

4) Having thus collected all possible information on the cost indicators of construction, you can transfer the results to a table where subtotals will be summed up for each type of construction and installation work.

5) After all the data is transferred to the table, from which the estimate will be formed with the necessary columns, such as: "Name of work", "Serial number", "Unit of measurement", "Quantity", "Cost of work", you can proceed to summing up the subtotals in the "Cost of work" column. The resulting value of the production cost of the planned construction works and required building materials should be discounted taking into account the estimated duration of construction or adjusted by other factors that will take into account the amount of unforeseen increases in prices, unaccounted costs, etc.

The described budgeting algorithm is just one of several options for marking construction and installation works. This method is applicable only in cases where the estimate is needed "for yourself", but not in any way for submission to other third-party organizations. At the same time, a self-made estimate will be a good help when working with a contractor, it will help to calculate the costs of the main construction work and, in principle, make an informed decision about the advisability of starting a new construction.

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 the 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 attract builders or do everything yourself. Not everyone knows how to make an estimate, which positions to include in it and how to calculate everything correctly. Let's try to figure it out.

What is the estimate

An estimate is a document that systematizes all the costs of upcoming construction or repairs. This can be easily done on your own, without having specially developed programs.

How to make an estimate on your own? It is enough to have Excel program on your computer. It is necessary to calculate funds and materials very carefully in order to avoid mistakes and exceed the planned costs. It should display everything to the smallest detail.

Common mistakes

When drawing up an estimate, many make mistakes, which then float out and provoke unforeseen waste:

• Calculations are carried out without a preliminary inspection of the object on which the work will be carried out.
• Additional costs that may arise in case of force majeure are not included.
• Not taken into account complete list works and materials.

The main expense document for repair or construction requires a serious approach and accurate calculations. Failure to do so may result in incorrect results.

What is needed for competent budgeting

Before drawing up an estimated estimate for construction or repairs, first of all, you need to inspect the object. After that, a list of all work carried out should be compiled.

How to make an estimate correctly? You need to know the construction technology. Without this, it is impossible to correctly and correctly calculate and record all forthcoming expenses. Therefore, we recommend, before making an estimate, to study the sequence of the production cycle of works that need to be assessed. 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;
• Work;
• transport.

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

In the first position, indicate the list of materials required for each cycle of work, unit of measure, 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 the Internet on sites specializing in the sale of building materials.

The second position includes a listing of all the actions to be performed. Here you need 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. This will require preparatory work: remove the old coating, clean the walls, prime them. Approximate cost necessary work can be found in the ads.

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

Drawing up an estimate for apartment renovation

How to make an estimate correctly in order to carefully plan the repair work in the apartment, to complete them in a short time with minimal costs? First, you need to decide what kind of repairs you will be doing: cosmetic or major. The amount of materials needed and the amount of work depends on this. If you decide to spend overhaul, then the estimate should be divided into two parts:

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

How to learn 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, 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 make an estimate for repairs. Prices and material consumption are fictitious.

Repair and finishing works:

Consumables and finishing materials:

Transport:

To obtain preliminary results expenses for apartment renovation, you need to add the total amounts from each column.

18819 + 7870 + 4000 = 30689 (rub.)

You should be aware 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 change production cycles and materials. How to make an estimate for construction with minimal costs? To do this, you need to carefully plan all the work, clarify what materials you need, find out the prices.

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

Today, after updating the estimated regulatory framework - GESN, TEP and FER, it will no longer be difficult to make an estimate for the construction of a house and calculate the exact cost of work.

Whether you are a private developer - building a house for yourself, or a major investor - building a house for a thousand apartments - building a house without an estimate calculation, as they say, is "more expensive for yourself." After all, the estimate includes all the costs necessary for building 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 estimate is made under standard construction conditions. Let's take the area of ​​the 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 literal sense of the word, - "to prepare the ground."

We will excavate soil for the foundation in a mechanized way. 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, let's take a quote:

FER01-01-013-03 Development of soil 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 Earthworks, all groups of soils are indicated, in our case these are "gravelly sands" which are more common in the central part of Russia. By the way, it is not in vain that we are digging a pit 1 m deep, because the depth of soil freezing in the same edges is 900 mm.

Foundation

We take as a basis the 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 inner walls, 6 m is 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 building a house:

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

Columns

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

Let's calculate the volume of our columns: 9 * 3.5 * 0.4 * 0.4 = 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 quote:

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

Load-bearing walls

Before calculating the amount of work on the construction of the walls, we will 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 * w19 * 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 obtain the volume of the masonry 60 * 3.5 * 0.4 = 84 m 3.

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

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

Beams

For structural rigidity, our columns must be connected at the top with a beam. The device of the beams could be performed simultaneously with the columns or the stage after the columns, but then there would be difficulties with the device of the formwork for them. And so, at this stage, the walls play the role of the lower part of the formwork, which greatly simplifies the work of tying reinforcement and laying the concrete mixture.

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

FER06-01-034-02 Arrangement 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 transferred the process of constructing the beams. We combine the binding of the reinforced frame of the beams and pouring with concrete with the viscous reinforcing frame of the floor and its concreting.

The overlap, in addition to what is 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 ​​the house is multiplied by the thickness of the floor - 100 * 0.16. Let's select a price:

FER06-01-041-01 Beamless slabs with thickness: up to 200 mm at a height from the reference area up to 6 m - 16 m 3

Roof

At the first stage, we will add a rafter device 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. Add about 30% to the area of ​​the house and get the area of ​​our roof, taking into account the overhangs and the slope. Let's take the following rate:

FER12-01-007-09 Roofing device made of galvanized steel: with wall gutters - 130 m 2

Conclusion

Well, that's all - our house is ready! You should not blame the author that he did not take into account all aspects of this construction and budgeting, the task was simply to show how the estimate is made and the amount of work is calculated.

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

The construction of any large facility, financial investments in which are very large, must be carried out with the calculation of the cost of all materials, performance of work and services, the price tag for the rental and operation of the used special equipment. That is why in the construction industry special settlement documents- estimates, in which all the costs for the construction of a certain real estate object are listed.

As an introduction, we will present such a document. Our focus is on 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 handed over to the customer. It describes in the most complete way where and for what purposes the funds allocated for the construction will be spent.

Even with the construction of 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 the construction of a house from different materials.

The composition of the document and who can develop it

Usually the estimate is based on project documentation facility 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 some special types of work arise, they are also included in the estimate as separate items with a price.

This type of documents can be developed either by specialized budget organizations, or by the designers themselves, who, together with the miscalculation of the project, are able to calculate the cost of its construction. The customer, before starting work, has the right to view an approximate estimate for construction and estimate his possibilities in terms of finance. 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 structure. How to make an estimate for building a house? A sample will help you figure it out.

We cope ourselves

For an independent assessment of the cost of a future residential building or construction on your site, the easiest way is to follow standard samples and calculate prices for materials and work. The article presents several estimates for different buildings. It remains only to substitute your values ​​for the lengths, types of materials used, their cost. For example, below are examples of estimates for the construction of a residential building.

The most convenient way to make such calculations is in Excel spreadsheets. However, this is where the complexity lies. All types of work must be presented in prices in one currency.

In what cases are several estimates drawn up?

If the house was built on a turnkey basis, then the customer only needs to require one document for the costs incurred. If several contractors are hired to perform different works, and exactly the same amount is drawn up.

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 a bar, 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. It should take into account the number of rooms in the project, the overall dimensions of the structure and how many in total square meters it will take. The next step is to identify the main groups of expenses. There will be several of them:

• The cost of acquiring the main The main in this particular case will be timber. Depending on the type of wood, its cross-section, operational characteristics, the total cost of this group of costs will also be found.
• The cost of other materials for building a house. This will include roofing, floor boards, and various wall cladding materials.
• The cost of finishing materials. These are various paints, parquet, wallpaper with tiles.
• Foundation costs. This part of the structure should be separated into a separate group and calculate in it the amount of material and its cost with delivery, as well as payment for the work of contractors.
• 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 are 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 distribute all the collected cost groups to the structural elements of the future house - the costs of the foundation, walls, roof and decoration.

The most important thing is to take into account when making calculations architectural features future structure, design direction, roof format, types and number of future communications, the need to use special equipment and attract professional builders, as well as the cost of delivering materials to the construction site and removal of construction waste.

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

Estimate 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, costs of transport services and installation types of work.

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

The timber is the main material. The first step is to calculate the number of beams needed to build a house. They are usually sold in cubic meters. And this is where the difficulty may arise when comparing the number of cubes to the actual amount 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 ​​the bar. Thus, the total volume of material in cubic meters required for construction will be obtained.

We introduce this indicator into the estimate, having previously calculated it at the market price.

Calculation of costs for foundations, roofing and finishing materials

First of all, you need to calculate the dimensions of the foundation, from which the volume of the required material will be clear. For 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 only remains to find out market value one cubic meter of concrete and multiply it by the resulting value.

Roofing materials are considered very easily. From the design documentation is taken 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. You will need to multiply the covered wall area by the cost of one square meter of each material separately.

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

Estimate for the construction of a frame house

The calculation of the costs for the construction of a frame house is not much different from that for a house made of timber. The only difference will be 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 work and Will good decision allocate some percentage of funds for unforeseen 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 below for a sample).

Foam block house

Before drawing up an estimate, you need to decide on the types of materials that will be used for construction. There are three types of blocks for the construction of houses - foam concrete, aerated concrete and expanded clay concrete. The best choice for construction in terms of performance is aerated concrete. Its price tag on the domestic market is not very 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 meter. V recent times became popular and foam concrete.

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

Mandatory clauses of the document

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

At the end of the calculations, the final figures are given. They are subdivided into direct costs, basic wages, equipment use, material and labor costs, overhead costs, and planned mark-up (the developer's profit).

Samples of 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 draw up a construction estimate, it is not necessary to involve specialists for this. You can do it on your own. For this, not much is needed - it will be enough to have a calculator, a project for a future house and monitoring market rates for building materials. Also useful are the samples of estimates for the construction of a house, given in the article. Even in the absence of professional skills, it is possible to see a rough picture of the total costs and significantly minimize them. If you have doubts about the correctness of your own calculations, you can contact the specialists.

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

The estimate for the construction of a house is the main document that should be prepared before the construction of the facility. Its availability allows you to accurately plan costs and decide on the purchase of suitable materials. The downside is that construction organizations an approximate amount is often called, because it is difficult to predict the costs of building a wooden, frame, brick house. There are many nuances that affect the final cost of construction. That's why in large companies whole departments have been created that are engaged in the preparation of estimates. If the company does not provide such a service, you have to contact special companies. Below we will consider what the essence of the estimate is, how to draw it up and give a sample for a general understanding of the process.

The term "estimate" in relation to the construction of a house is a special document, without which no contracting organization starts work. During the construction of a building, most of the costs are spent on building materials and the remuneration of builders. That is why all the nuances are taken into account in the process of calculating the price:

• The amount of work performed.
• Applied technologies.
• The period of building a house made of bricks, foam blocks, aerated concrete or other material.
• The number of workers who are involved in the process.
• Investment options for the project and so on.

The availability of an estimate allows the owner to control the progress of construction work and the cost of building the facility. As a result, it is possible to form a schedule of activities and force the builders to strictly adhere to the established plan. Often, at the beginning of construction, the owners are reinsured and apply for an estimate to several companies at once. Moreover, the difference in final price can be quite significant.

The reason for the runaway in the bottom line is different prices from suppliers of materials, the individual cost of performing work for each company, and so on. Comparison of the estimate documentation received in different companies allows you to roughly estimate the costs of building the facility and take adequate measures to reduce costs.

How to make a construction estimate correctly?

In the calculation process, many costs are overlooked and not taken into account by customers. As a result, the final price is higher than the stated one. For example, the bureaucratic component leads to an additional 15-20 percent of expenses. Transport costs may seem insignificant, but in reality they also amount to 5-10% of the planned budget.

When drawing up estimate documentation, it is worth knowing the following:

• The calculation is carried out taking into account all positions of the documents.
• If another company is engaged in the calculation, it is necessary to check the obtained parameters and adjust them taking into account the current realities.
• Estimated construction documentation should be coordinated with experts in this area.

In addition to minor expenses, a certain amount of funds should be planned for unforeseen costs. They are allocated in the estimate up to 2-4% of the total amount. In this case, the real amount reaches 4-5%.

Estimated documentation is the main element in construction, therefore, its preparation is carried out according to special rules. Many of them work and remain unchanged since the days of the USSR. For example, earlier the estimates were made by organizations that were involved in the development of project documents. The organization charged 10% for the creation of the project and another 1% for the estimate documentation.

Today, the calculation processes are automated, there are special programs, and before the eyes of companies there are ready-made examples... It remains to insert the required parameters and give a command to perform calculations. Despite the availability of software, difficulties appear in another aspect - the range of materials has increased, the number of suppliers and construction companies has grown. Overpayment or savings on estimate documentation depends on the qualifications of the employees who took up this work. At the same time, you should not save a lot on materials, because this leads to a loss of quality.

Types of estimates

In accounting, the calculation of the estimate before the start of construction is not always possible. This is due to the regular rise in prices for raw materials, materials, the work of people and the tools used. Also, you cannot take into account the likelihood of force majeure, due to which the cost of work will be much higher. For this reason, before accurate calculations appear, it is worth applying estimate calculations, on the basis of which object calculations are created. In the latter, edits are made as necessary. The estimate is drawn up using the estimate norms that are available in the special documentation.

Local - estimates that are determined estimated price erected structure. Such a document applies to all types of work and costs. Estimating is possible for an object as a whole or for a category of work - building a foundation, erecting a roof, and so on.

Object estimate - paper, which contains information about the structure being repaired or being built. The information is taken from a local estimate.

Consolidated estimate documentation - papers that are drawn up on the basis of object estimates for specific types of expenses.

Compilation methods

There are several calculation methods. To do right choice, it is worth knowing the features of each of them:

• Time consuming method. This technique is used for structures with small dimensions. Construction company announces to the client the final costs that await him in the event of an order. In addition, the problems with the delivery of materials are solved directly by the contractor. With this method, no contract is drawn up, and the contractor does not guarantee anything. As a result, there are pitfalls in the estimate documentation, which are almost impossible to notice without a detailed study.
• A universal method. With this methodology, the document includes a section in which the main works are listed in stages. With the help of such documents, it is easier to control the construction process and costs. In addition, the customer has information on the cost of the materials used, as well as data on costs. With the help of estimate documentation, it is possible to keep costs under control. For example, the overhead structure includes wage workers, tax payments and additional costs.
• Expanded estimate documentation. It is easy to judge about its features by the name of the method. Drawing up such an estimate is necessary when performing construction work. In addition, a detailed statement of the estimate for the construction of the object shows the customer the real state of affairs and the current cost of building materials (tools, works). It is not difficult to understand the documentation even for an uninitiated customer in the subtleties of drawing up.

Components of the estimate

As noted earlier, when drawing up estimate papers, many components are taken into account - the type of contractor, the type of activities performed, the specifics of the work, as well as other aspects of the activity. That is why each estimate compiled by different firms has significant differences, and the final parameters will differ for the construction of different types of buildings.

In addition, the estimate documentation drawn up during the construction of an object for their own needs will differ from that which is formed by contracting companies. In the latter case, a number of elements are overlooked. If you decide to draw up an estimate with your own hands, you should figure out its composition and adhere to the structure:

• General information about the document. This information is located on the title (first) page of the documentation. They usually contain information about the contractor and the customer, the name and date of compilation. In addition, details are indicated that would confirm the approval of the estimate documentation.
• Construction section. Here information is grouped by topic, making the papers easy to understand and interpret. Sections can have different names - "Finish", "Repair" and so on.
• List of materials. When filling out this section, the resource methodology, which was considered above, is used, as well as the system of indices for the performance of construction work (used in construction). For each of the positions, personal information is presented - the number in order, the resource code according to the directory, and so on. Estimated documents for an object - papers that contain information about the object being built (restored). Data is taken from local settlements and securities. It also lists the required number of materials, the cost (for each specific unit) and the total price.
• List of works on the construction estimate. In this section, for each of the items, the order number, code, name and unit of measurement, the number and labor costs of workers and machinists, the number of man-hours, the average category of employees involved, tariffs, wages, and so on are indicated.
• The list of mechanisms, transport and devices that are necessary for the performance of work, taking into account the current estimates for construction. For each of the positions, such information is indicated - number in order, code, name vehicle(device, mechanism), measuring unit, the number of units for operation, the required number of equipment to perform the work, the cost of the position, and so on.
• General expenses for estimate documentation. In a separate column, the size of the salary fund, the price of the materials used and the cost of using mechanisms and devices are prescribed.
• Various coefficients, surcharges, discounts, overheads, and other parameters that are calculated as a certain percentage of the total amount for the estimate.
• The amount of VAT is a parameter that is calculated from the final parameters of the estimate documentation, taking into account additional information.

Also, the estimate indicates total amount estimates, full name and signature of the compiler and the verifying party. These sections are usually sufficient to obtain the total cost of construction work.

How is the construction estimate calculated?

Log house

In order to properly invest money in the construction of a house from a bar, it is important to determine the quality of the materials used, the cost of transport and installation. When calculating costs, it is worth taking into account the type of structures used, the cost of a unit of production, the number of required objects, the total price of the entire volume of materials. In addition, the costs of transportation and movers are added to this amount.

A bar is used as the main material. When making an estimate, it is important to calculate the volume of the required timber, which is sold per cubic meter. meters. At this stage, difficulties arise. To cope with them, it is worth knowing the perimeter of the object (indicated in the technical documentation), and then multiplying the resulting parameter by the height. After that, the total number is multiplied by the sectional area. The total volume is obtained in cubic meters - this material is enough for the construction of an object. Next, it remains to include the number in the estimate, taking into account the market price.

An equally important step is calculating the cost of roofing, finishing and foundation. It is worth starting from the base of the building. To solve the problem, it is worth multiplying the perimeter by the thickness and height of the base. As a result, data on volume remains on hand. As soon as the calculation is completed, it remains to find out the market price of one cubic meter of concrete, and then multiply the resulting parameter by the existing value.

It is not difficult to calculate the material for the roof. Take the roof area from the project, and then multiply the parameter by the cost of the "square" of the selected material. It is more difficult to calculate the cost of finishing, because different types of materials are used here. When calculating, the cost of the wall is multiplied by the price of the "square" of each material separately. After completing the calculations, it remains to combine the costs and summarize.

Estimate for the construction of a frame building

The calculation of costs for the construction of a frame building is carried out according to the same principle as discussed above. The difference lies in the material used. To perform calculations, it is worth having at hand information on the shape and size of the structure. It is also worth considering the costs of roofing, finishing and installing the base. The estimate includes transport and loading costs. An important point- allocation of a certain percentage of costs for force majeure. These points are sufficient when drawing up an estimate for the construction of a frame building.

Foam block house

For an accurate calculation of the estimate, it is worth determining the material that will be used when performing construction work. There are three types of blocks for construction - foam concrete, aerated concrete or expanded clay concrete. The best solution for today is the use of aerated concrete (including from a price point of view). If a house is being built with an area of ​​300 "square", then the total price of aerated concrete will be from 30 thousand rubles.

Sample

To make it easier to draw up a construction estimate, it is important to have a ready-made sample of the document in front of your eyes.
