An estimate for a country house is an example. Calculation of estimates and construction of a private house
Estimating the construction of a house -. Decisions made by designers can seriously affect the cost of construction, increasing or decreasing the cost of work or materials.
And if the decrease in cost does not bring problems to the developer, then its increase can seriously damage the reputation of the company, especially. If it occurs after the approval of the total amount with the customer.
House construction estimate
House construction estimate reflects the costs that need to be carried out for all types of work, for example,. Of course, it is simply impossible to calculate everything, so the estimate for building a house should also include unforeseen expenses. Unforeseen expenses can be approximately 2%. However, a construction firm cannot take money just for the cost of the work. She needs to make a profit and give workers a salary. Basically, 15% of the total amount is allocated for these needs.
In the estimate for the construction of a house, you can also take into account all kinds of unforeseen expenses. As you know, they account for about 2%. And, of course, the budget should include the profit of the company. Basically, about 15% of the total amount is allocated to it. This part of the amount is needed, because no one will act to their own detriment. As a rule, the client is allowed to edit the estimate, he has the right to agree on the type of plumbing used, the presence or absence of built-in furniture and other issues. If the customer wants to purchase something on his own, then this must also be negotiated and recorded in special documentation.
The estimate has great benefit- in the future, she will be great helpers in controlling the stages of construction, as well as payments for the work done.
How to make an estimate for building a house
To make an estimate, you need to take the calculation of labor costs as a basis and write out all the work. Using the spreadsheet editor M. Excel is extremely convenient to do this. The difficulty lies only in finding all the jobs in EPERs (unified district unit rates). These documents are selected depending on the area of construction. This is very important, since in different cities the cost of work, as well as materials, are different.
To answer the question: how to make an estimate for building a house, it should be noted that it is necessary to have collections of EPEPs also in electronic form (to facilitate the search). When drawing up an estimate, as well as when drawing up a calculation of labor costs, opposite the planned work, their volume is entered, converted into the units of measurement indicated in the herers, for example, in 100m2 or 1000m2 ... Then, direct costs are written out from the collection. In the adjacent three columns, the costs of wages, the operation of machines and mechanisms, and the costs of materials are entered. These three columns add up to the direct costs.
After that, it is necessary to calculate how much the cost of the work will be, namely the direct costs of the specified amount of work (it is also considered how much must be paid to workers, allocated for the purchase of materials and depreciation of machines and mechanisms (the latter also includes the operator's salary)).
What should be in the construction estimate
The following are counted under the entire table:
- Total direct costs
- Total cost of basic wages
- Total cost of operating machines and mechanisms
- Total cost of materials
- Total equipment cost
- Total standard labor costs
- Total overhead
- Total planned savings ( estimated profit)
- Total planned savings.
Despite the amount of work done, we have not yet received the cost of construction, for this we need to calculate:
- TOTAL COST OF THE CONSTRUCTION CONTRACT in 1984 prices
- TOTAL COST OF THE CONSTRUCTION CONTRACT in 1991 prices
- TOTAL COST OF THE CONSTRUCTION CONTRACT AT THE CURRENT LEVEL.
The last resulting value will be the construction cost.
In this lesson, we come close to defining construction cost... All data were obtained using EPEP. Having this table and being able to navigate according to the specified collection of standards, you can find out the direct costs. They include wages, the operation of mechanisms and machines, as well as the cost building materials... You will learn how to compose local estimate for the construction of a new facility.
In order not to burden you with the calculations associated with the translation at the rate of the results obtained in rubles, I will simply say that this work is done for you by the table under the main table. There is no need to publish it in this article, since you need to explain the points associated with it. Below is a local estimate that constitutes the largest and most important part of the economic section of a home project. In addition to it, you need to prepare:

Content
The estimate for a private house is the most important document on the basis of which all work is carried out on the arrangement of the site and the construction of residential structures. It is important to be able to calculate the construction of a house yourself. In this case, insurance against deception and fraud in construction and contractors will be guaranteed. This page provides basic information on estimates for private houses. Described how the calculation of the cost of construction is carried out country house.
The cost of building a residential stone house often depends on various factors with unstable characteristics.
The main items of expenses for the construction of a house are as follows:
- purchase and registration costs land plot;
- payment for the production of a complete package of technical documentation (design and approval);
- the costs of connecting to the existing networks of engineering communications;
- purchase and transportation of building materials to the site;
- payment for the work of the involved equipment and specialists;
- unforeseen expenses in cases of various force majeure circumstances.
Prices for all of these costs vary considerably. If the size of state fees is the same in all regions, then the prices for the services of various organizations preparing technical documentation vary greatly.
The cost of building materials depends on the region, as does the price of specialist services.
Estimates for building a house and purchasing a plot
The estimate for building a house begins with the cost of acquiring a plot. Currently, there are only two legal ways to acquire ownership of a plot of land: buy from the previous owner, or redeem from state or municipal property.
Buying a piece of land from a private owner is much easier. It doesn't take a lot of time. However, its price can be significantly higher than that of an equivalent plot in the case of redemption from state property.
There is a theoretical possibility to get a piece of land from state ownership for free. However, the number of people who have this legal right is negligible.
To buy a plot of land from the owner, you must conclude a written sales contract with him in accordance with the requirements set out in § 7 Chapter 30 of the Civil Code Russian Federation(Art. Art. 549-552, 554-557).
The contract must provide for the following conditions:
- the subject of the agreement (clearly indicate the data allowing to establish the conformity of the land plot to be sold: the category of land, including the intended purpose, the area of the territory);
- the price of the sales contract agreed by both parties.
After agreeing on all the details of the sale and purchase agreement and signing it, it is necessary to issue state registration of the transfer of ownership of land.
To do this, you need to contact the appropriate justice authority at the location of the acquired site by submitting the following documents:
- registration application;
- a receipt for payment of registration;
- contract of sale;
- documents proving the identity of the buyer;
- cadastral plan.
The institution of justice examines the adopted documents and issues a decision on state registration.
The justice authority puts marks on all documents of title and after that issues a certificate of state registration of ownership of the land plot. This completes the procedure for acquiring a land plot.
Much more complicated is the situation with the redemption of a land plot from state ownership. According to the legislation, a land plot intended for construction can be transferred to private ownership only as a result of an auction (auction).
Land acquisition is carried out in the following order:
- an application is submitted to local self-government bodies with a request to provide a land plot for the construction of a residential building;
- a topographic plan of this site is ordered from a special licensed organization;
- after receiving a copy from topographic plan an application is submitted to clarify the absence of encumbrances related to this site;
- when all the above documents are collected, an application is submitted on the absence (or presence) of building bans on this site;
- the entire package of documents is submitted to local executive authorities or self-government bodies for making a final decision.
On the basis of the submitted documents, local authorities decide on an auction, the subject of which is the ownership of the land plot.
The auction is held within a month after the decision to hold it is made. If, apart from the initiator of the auction, no one has expressed a desire to participate within a month, the applicant has the right to buy out the land plot by paying its nominal value.
The protocol of the results of the auction serves as the basis for the execution of the contract for the sale and purchase of the land plot. In practice, a three-year lease agreement is concluded between the auction winner and the local government. During this time, the developer is obliged to erect buildings according to the intended purpose of the site. Only after that the site is finally transferred to the owner in private ownership.
Approximate costs of acquiring a land plot. The amount of state fees for various actions in relation to land is small. But most of the activities for the registration of land ownership are carried out by licensed firms. They charge service fees according to their own price lists.
An example of an estimate of a residential country house
Further, an estimate for a residential building is offered as an example of documentation. An example of an estimate for a house can be used when drawing up own project... It is worth remembering that the estimate of a country house may have different parameters depending on the region of construction. Economic conditions in different regions of the country form different prices for building materials, vehicle services and construction work. It is impossible to present a correct calculation that would contain real prices that correspond to reality in all areas.
Sample: how to calculate a construction estimate for a house
How to calculate the estimate for the house correctly and put all the necessary parameters into it? Construction estimate for building a house can be compiled using various specialized programs. The following example of an estimate for building a house will tell you what parameters should be taken into account in this process. An approximate calculation of the cost of building a house in the table "Calculating the cost of building a house with a total area of 215 m2." The table shows the work that needs to be done when building a house. Substituting in the proposed calculation the real cost of materials in a particular region, you can calculate with great accuracy the costs of building a stone house.

Several years ago, there was a surge in individual housing construction... Currently, due to a number of economic reasons, construction activity has declined. Despite this, entrepreneurs are mastering the production of new building materials. There are many new domestic roofing materials meeting the most modern requirements. A wide selection of power tools allows developers to do jobs on their own that they never dreamed of before.
Not a single serious construction of a house begins until an estimate is drawn up and approved for it. This is a mandatory document that allows you to calculate construction costs with a high degree of accuracy, as well as control the expenditure of funds in the process of building a particular structure.
However, budgeting for the construction of a home is not an easy task. Not only a private developer, but not every contractor will be able to do it correctly, taking into account all the items of expenses and unforeseen costs. Therefore, the most powerful construction companies have their own budgeting departments, while smaller companies can turn to specialized offices, for which budgeting is the main activity.
The estimate for the construction of a house is a financial document and an integral part of the contract for the construction of a house, no matter what form of ownership the organization is a contractor. When drawing up estimates for construction, two main categories of costs are assumed:
- for building materials;
- to perform work;
At the same time, one cannot do without a thorough study of technical and organizational issues, in particular:
- determination of the scope of work,
— construction time,
- applied technologies,
- the amount of materials;
- the number of working personnel;
- forecast of volumes and stages of financing.
In addition, the estimate for the construction of a house allows you to clearly track the compliance of the work performed with the approved schedule, which is very convenient from the point of view of technical control and architectural supervision. I must say that budgeting is a process that fully justifies itself and pays for itself in the process of building a house.
Drawing up a construction estimate allows the customer to carefully consider all stages of the work, and if it is necessary to make amendments even before the start of work in the material. For construction company this document helps to minimize bureaucracy and uncontrolled reproduction of paper and electronic documentation. In addition, having a project and an approximate estimate, the customer gets the opportunity to hold a tender for the performance of work among contractors. And in the future, control the quality of work and the amount of material remuneration.
A fairly wide practice is to order estimates for a specific object to different design or construction organizations. As a result, the client receives several estimates with a fairly wide price range. This is possible because different companies have different prices, different suppliers of building materials, different vehicles and the number of staff. Accordingly, comparing the estimates, quality indicators various materials, you can understand what the difference is.
Construction companies that value their reputation can involve the customer in the discussion of the estimate, indicating the places where and at the expense of what you can save, and where the savings will not lead to anything good.
Sections of the estimate for the construction of a house
The estimate for the construction of a house includes many items that at first glance may seem optional. But practice shows that this fully justifies itself. For example, the operation of transport, the cost of bureaucracy, approval, receipt different kinds permits from officials. By the way (we draw your attention to this), as practice shows, this item of expenditure can be up to 15% of the total cost of the object. But if we talk about mandatory positions, then this includes:
- development and compilation of all positions estimate documentation in accordance with the design solution;
- checking and optimization of estimates, in the case of their compiled by a third-party organization;
- protection and approval of estimates in expert organizations;
In each estimate there is such an item as unforeseen expenses. In theory, it is generally accepted that such unforeseen expenses can be up to 2%. But in practice, this figure can be either 5 or 10%. At the same time, it is important that after all the discussions and approvals and changes, the estimate for the construction of the house must be officially approved and signed by the customer himself.
Estimating rules
Budgeting as a financial document has its own rules. Some of them have come down to us since the times of the USSR. In those days, the estimate was made exclusively by the design organization itself, without any alternative. She was an integral part project documentation... Since then, the practice of estimating the cost of budgeting has been established in direct relationship with the total cost of work. This value was 10% of the project cost. But if then the cost of the project was estimated at 10% of the total cost of construction and installation work, then the estimate of the entire project cost about 1-2% of the total cost of construction. In some places, this formula is still valid, especially when developing estimates for the construction of state and budgetary facilities. However, this practice and this form of calculation is less and less common.
With the introduction of computer technology, the budgeting process is becoming more and more automated. For this, many automated programs have been developed that use a standardized database.
This approach to business greatly simplified the budgeting process, but at the same time neutralized the factor of her individuality. Diversity in pricing, including the lack of a unified regulatory framework for commercial pricing, also had a negative impact on the situation. The final figure is very seriously affected by the level of qualifications of the involved specialists. It's no secret that the cost of labor in the current construction market is very, very variable and, unfortunately, the main source of savings.
Types of estimated calculations
There are three main models for budgeting: the labor-intensive method, the calculation by aggregated indicators, and the detailed estimate. Each of them has its own advantages and its own right to exist.
Labor-intensive calculation method is most beneficial for small teams
1. Labor-intensive method.
It is used, as a rule, in those cases when it comes to contracting teams that somehow completed the work. In this case, the contractor strives in every possible way not to leave the ends, that is, coordinates, written confirmation and contractual obligations. The contractor names the customer a certain amount necessary to ensure wages, which are calculated based on the aggregated indicator of the cost of construction and installation work, more precisely for 1 m2 or linear meter, or the total area of the premises. At the same time, the services for the delivery of consumables and for their configuration are completely shifted to the customer's side and nowhere else do they appear in monetary terms.
This option may seem quite tempting for the customer due to the low cost with a complete lack of understanding of the system for forming the final amount. At the same time, the cost of consumables is almost always comparable to the total cost of work. The method, of course, is somewhat primitive, but, nevertheless, it is often the only possible one when performing work with a low-budget customer and a not-too-qualified contractor.
2. A universal method.
Such an estimate is drawn up in the form of a document in which the main stages of work are listed in an enlarged form. In a separate appendix of such an estimate, a list of all materials used, their market price and transportation costs is given. The presence of such a document allows the customer to specify the cost of the most common types construction works and their volumes. In addition, it enables the customer to conduct a spot check of the real cost of the materials used.
As a rule, an estimate of this type consists of no more than 60 types of prices and 30-40 items for materials. But in this version of the estimate, in addition to the cost of materials, additional cost items appear. It can be fare in the amount of 5-7% of the cost of materials, the cost of depreciation of the tool. The rest - overhead costs - salaries of engineering staff and management, rent of premises, taxes, etc. The projected profit is "hidden" either in the salary category or in the cost of materials section.
When it comes to large objects, you cannot do without a detailed estimate for the construction of a house.
3. Detailed estimate.
This option involves the complete preparation of a package of estimate documentation in the form approved by law. Such estimated standards are formed on the basis of special technological maps and calculations, as well as a series technical conditions and types of work. The organization making the estimate is obliged to own the latest achievements in the field of construction technology, to have the latest information on new materials and technologies. This option for preparing the estimate is also the most promising because the form for submitting the estimate documentation is the most understandable and accessible to the average customer.
Consider an example of an estimate for the construction of a capital house. The enlarged estimates for houses with an area of 100m2 and 200m2 will be considered.
