Building a house is a troublesome and expensive task. Can you estimate how much it will cost you to build it? Unfortunately, not every organization will undertake to tell you a certain amount, because it is very difficult to take into account all the nuances, pitfalls and unforeseen expenses during construction. That is why large construction companies have entire departments for preparing estimates. Those companies that do not have such departments turn to specialized companies.

Estimate is...

An estimate for the construction of a house is a mandatory document, without which no contractor will begin work.

As a rule, when constructing a building, the largest costs are for construction materials and payments to contractors. When calculating the cost of work, the following are taken into account:

• Scope of work;
• Technologies that will be used;
• Construction time;
• How the project will be financed (time frame and volumes).

Using the estimate, the customer can control the construction time frame, the compliance of the planned work and the work completed over a certain period.

Thus, an estimate for the construction of a house helps to streamline the work schedule and the flow of finances during the work.

Often, having decided to build, clients submit applications for estimates to several companies at once. The difference in the final cost of the building can be significant. The reason for this phenomenon is different suppliers of materials, number of workers, etc. By comparing estimates from different organizations for the same amount of work, you can objectively assess how you can wisely save money without sacrificing quality. .

Important details when drawing up an estimate

Very often, insignificant costs, which many do not take into account, result in large sums. For example, resolving bureaucratic issues can take up to 15% of the cost of the property. Transport costs may also seem like a small thing. Without taking them into account, you will be very surprised at the final cost of the building. However, the following items are required:

• Development of estimates for all documentation items;
• If the estimate was prepared by another organization, mandatory verification and adjustment;
• The estimate for building a house must be agreed upon by expert organizations.

In addition to minor expenses, a certain percentage of the funds spent are unforeseen expenses. In the documentation they are allocated 2%, but very often the actual figure exceeds the planned one.

How are estimates prepared?

Due to the fact that the estimate is the most important financial document, its preparation is carried out according to certain rules. Some of them were approved back in Soviet times. For example, previously the estimate was drawn up by the organization that developed the project. She received 10% (of the cost of construction work) for and, accordingly, 1% for the estimate.

Sometimes this practice still occurs, but in general today processes are automated. Despite the presence of various programs, it is still more difficult to prepare estimates than in those days due to the variety of modern materials, technologies, construction companies, etc. Depending on the qualifications of workers and competition, you can overpay or save. But savings do not always benefit quality.

Three methods for calculating estimates

Let's look at what types of calculations there are and in which case which type is better to use.

1. Estimate for building a house, compiled using a labor-intensive method. Often used for small buildings. The construction company tells the client the amount necessary to pay for their services, and the materials and their delivery are provided by the customer himself. With this method, there are no written agreements or guarantees on the part of the contractor, but it does exist. .

1. Universal method. The document consists of a section where the main points of the work are listed step by step, as well as an appendix indicating the cost of materials and their transportation. Such an estimate for building a house will help you better control costs. Disadvantage - the document does not fully reflect some types of costs. For example, “overhead costs” mean salaries, taxes and several other expense items.
2. Detailed estimate. The name speaks for itself. Such a document must be drawn up for large-scale construction. The most detailed estimate for building a house reflects only the latest information on prices for building materials and other cost components. The documentation is easy to understand even for an uninitiated person.

Below are examples of prepared estimates.

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

Whether you are a private developer - building a house for yourself, or a large investor - building a house with a thousand apartments - building 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 look at the main stages of drawing up an estimate for the construction of a private house and you will be able to download it.

In our example, we will not take into account all possible complicating construction factors; we will assume that the cost estimate takes place under standard construction conditions. Let's take the area of ​​the house to be 100 m2 (10*10).

Of course, if you are not going to put up a tent or temporary shelter, then you cannot do without taking into account the cost of excavation work in the estimate. After all, to lay a foundation it is necessary, in the literal 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, let's take the price:

FER01-01-013-03 Soil development with loading onto dump trucks using excavators with a bucket capacity: 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 “gravel sands”, which are more common in the central part of Russia. By the way, it’s not in vain that we are digging a pit 1 m deep, because the depth of soil freezing in the same area is 900 mm.

Foundation

Let us take as a basis a strip monolithic reinforced concrete foundation. We design the foundation for external walls, i.e. along the perimeter of the house, as well as under load-bearing walls - conventionally, 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 external and internal 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 - this is the thickness of the foundation. Now let’s select a price for our estimate for building a house:

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

Columns

The most optimal and common option is to install 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, having built a one-story house, 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 the following price:

FER06-01-026-15 Construction 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 involved in constructing the walls, let’s determine for ourselves that we will make all the load-bearing walls (remember, we made the foundation for them) from common cinder block (w19*h19*d39) and place 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 .

Let's continue to draw up our estimate for building a house and take the following price for laying load-bearing walls:

FER08-03-002-01 Laying walls of lightweight concrete stones without cladding: for floor heights up to 4 m - 84m 3

Beams

For structural rigidity, our columns must be connected at the top with a beam. The construction of the beams could be carried out simultaneously with the columns or a stage after the columns, but then there would be difficulties with the installation of formwork for them. And so, at this stage, the walls act as 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 section of the beam is equal to the section of the columns - 400 * 400 mm. From here we get 10.6 m3. For an estimate for building a house, choose the price:

FER06-01-034-02 Construction of beams for ceilings, cranes and strapping at a height from the supporting platform: up to 6 m with a beam height of up to 500 mm - 10.6 m 3

By the way, it was not for nothing that we postponed the process of installing beams. We combine the tying of the reinforced frame of the beams and the pouring of concrete with the tying of the reinforced frame 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. That's why we'll make it reinforced concrete!

For our estimate for building a house, the volume is calculated very simply - the area of ​​the house is multiplied by the thickness of the floor - 100 * 0.16. Let's choose a price:

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

Roof

At the first stage, we will add rafter installation to the estimate at the following price:

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

On the second, we will cover our roof with galvanized iron. Let's add about 30% to the area of ​​the house and get the area of ​​our roof, taking into account the overhangs and slope. 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 home is ready! The author should not be blamed for the fact that he did not take into account all aspects of this construction and drawing up an estimate; the task was simply to show how an estimate is drawn up and the amount of work is calculated.

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

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

What is an estimate

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

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

Common mistakes

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

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

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

What is necessary for competent budgeting

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

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

Main items of the estimate

Any construction estimate consists of three main items:

• materials;
• Job;
• transport.

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

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

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

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

Drawing up an estimate for apartment renovation

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

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

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

Example

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

Repair and finishing works:

Consumables and finishing materials:

Transport:

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

18819 + 7870 + 4000 = 30689 (rub.)

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

30689 + 15% = 35292.35 (RUB)

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

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

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

Composition of the construction estimate

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

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

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

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

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

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

Acquisition of land and performing calculations

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

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

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

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

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

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

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

How to make an estimate

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

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

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

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

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

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

Cost calculation for foundation, roofing and finishing materials

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