Samples of estimates for building a house. Features of budgeting

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 special equipment used. That is why in the construction industry, special settlement documents are used - estimates, in which all the costs for the construction of a certain property 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 the design documentation of the 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 capabilities 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

To independently assess the cost of a future residential building or construction on your site, it is easiest 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 is necessary to take into account the number of rooms in the project, the overall dimensions of the structure and how many square meters it will occupy in total. 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 to build a house. This will include roofing, floor boards, and various wall cladding materials.
The cost of materials for finishing. 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 estimates are almost the same as those that make up the estimate for the construction of a wooden house (you can see a sample in the photo below).

Detailed analysis of available information

So, the initial stage is 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 that when calculating, it is necessary to take into account the architectural features of the 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 costs of delivering materials to the construction site and removing 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, it is necessary to take into account the following basic parameters: type, unit price, required quantity and total cost for the entire volume. The costs of transport and the work of loaders are added to this amount in a separate line.

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. All that remains is to find out the market value of one cubic meter of concrete and multiply it by the resulting value.

Roofing materials are considered very easily. The total roof area of the house is taken from the design documentation, 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 area of the wall 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 It would be a good solution to allocate some percentage of the money 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. Recently, foam concrete has also become popular.

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 work, the cost of wages 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 the sample above). Good luck in compiling it!
