Sample estimate for foundation work in excel. Estimate for work - sample, form and example of preparation

There are “alternative estimate documents”, please order if you wish. Samples of document forms are mainly used for internal use in order to view in detail and calculate the costs included in the estimate documentation. They eliminate the need to use a calculator and have any in-depth knowledge of budgeting.

Examples of estimates and calculations for construction, repair and installation:

Examples and sample documents are presented tentatively and therefore serve as a guide for understanding the work being performed. All requirements for estimate documentation and acts are indicated in the letter and then agreed with us.

Standard forms of documents (sample) for construction:

Help on form KS3
Defective statement (bill of quantities)
Consolidated estimate calculation (SSR)
Object estimate (OS)
List of resources (calculation of material requirements)
Local estimate calculation (LS)
Costing for work in Excel

The estimate for the construction of a house is the main document that should be prepared before the construction of the facility. Its presence allows you to accurately plan expenses and decide on the purchase of suitable materials. The downside is that construction organizations often give an approximate amount, because it is difficult to predict the costs when building a wooden, frame, or brick house. There are many nuances that affect the final cost of construction. That is why large companies have entire departments dedicated to preparing 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 provide 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 contractor begins work. When constructing a building, the biggest costs are construction materials and labor costs for construction workers. That's why all the nuances are taken into account in the process of calculating the price:

• Scope of work performed.
• Technologies used.
• The period of construction of a house made of brick, foam block, aerated concrete or other material.
• The number of workers who are involved in the process.
• Project investment options and so on.

Having an estimate allows the owner to control the progress of construction work and the costs of constructing the facility. As a result, it is possible to create a schedule of activities and force builders to strictly adhere to the established plan. Often, when construction begins, owners play it safe and submit applications for estimates to several companies at once. However, the difference in the final price can be quite significant.

The reason for the difference in the final indicators is different prices from material suppliers, the individual cost of performing work for each company, and so on. Comparing estimate documentation obtained from different companies allows you to roughly estimate the costs of building a facility and take adequate measures to reduce costs.

How to draw up a construction estimate correctly?

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

When preparing estimate documentation, you should know the following:

• The calculation is carried out taking into account all document positions.
• If another company is involved in the calculation, the obtained parameters must be checked and adjusted to take into account current realities.
• Construction estimates should be coordinated with experts in this field.

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

Estimate 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 times of the USSR. For example, previously estimates were drawn up by organizations that were involved in the development of project documents. The organization took 10% for creating the project and another 1% for the estimate documentation.

Today, calculation processes are automated, special programs appear, and companies have ready-made examples before their eyes. All that remains is to insert the required parameters and give the command to perform the calculations. Despite the availability of software, difficulties arise 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 on this work. At the same time, you should not save much on materials, because this leads to a loss of quality.

Types of estimates

In accounting, calculating estimates before construction begins is not always possible. This is due to the regular increase in prices for raw materials, materials, people’s work and the tools used. You also cannot take into account the likelihood of force majeure, due to which the cost of work will be much higher. For this reason, until the advent of accurate calculations, it is worth using estimate calculations, on the basis of which object calculations are created. The latter are amended as necessary. The preparation of estimates is carried out using estimate standards, which are available in special documentation.

Local - estimates that determine the estimated price of the structure being built. Such a document applies to all types of work and expenses. It is possible to draw up an estimate for an object as a whole or a category of work - building a foundation, erecting a roof, and so on.

Object estimate is a paper that contains information about the structure being repaired or constructed. Information is taken from the 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 make the right choice, you should know the features of each of them:

• Labor-intensive method. This technique is used for structures with small dimensions. The construction company announces to the client the final costs that await him in the event of an order. In addition, problems with the delivery of materials are resolved directly by the contractor. With this method, no contract is drawn up, and the contractor does not guarantee anything. As a result, the estimate documentation contains “pitfalls” that are almost impossible to notice without a detailed study.
• Universal method. With this technique, the document includes a section in which the main works are listed by stages. With the help of such documents, it is easier to keep control over the construction process and costs. In addition, the customer has information on the cost of the materials used, as well as cost data. With the help of estimate documentation, it is possible to keep costs under control. For example, the structure of overhead costs includes employee wages, tax payments and additional expenses.
• Detailed estimate documentation. By the name of the method it is easy to judge its features. Drawing up such an estimate is necessary when carrying out construction work. In addition, a detailed statement of the estimate for the construction of the facility shows the customer the real state of affairs and the current cost of construction materials (tools, work). Understanding the documentation is not difficult even for a customer uninitiated in the intricacies of its preparation.

Components of the estimate

As noted earlier, when drawing up estimates, many components are taken into account - the type of contractor, the type of activities performed, the characteristics of the work, as well as other aspects of the activity. That is why each estimate prepared by different companies 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 a facility for your own needs will differ from that prepared by contracting companies. In the latter case, a number of elements are overlooked. If you decide to draw up an estimate yourself, you should understand its composition and adhere to the structure:

• General information about the document. This information is located on the title (first) page of the documentation. As a rule, they contain information about the contractor and the customer, as well as the name and date of preparation. In addition, details are indicated that would confirm the approval of the estimate documentation.
• Construction section. Here the information is grouped according to specific topics, which makes the papers easy to understand and interpret. Sections can have different names - “Finishing”, “Repair” and so on.
• List of materials. When filling out this section, the resource methodology discussed above is used, as well as a system of indices for the performance of construction work (used in construction). For each position, personal information is presented - serial number, resource code in the directory, and so on. Estimate documents for an object are papers that contain information about the object being constructed (restored). Data is taken from local calculations and papers. The required number of materials, cost (for each specific unit) and total price are also given here.
• List of works according to construction estimates. In this section, for each item, the serial number, code, name and unit of measurement, the number and labor costs of workers and drivers, the number of man-hours, the average category of workers involved, tariffs, wages, and so on are indicated.
• A list of mechanisms, transport and devices that are necessary to perform the work, taking into account the current construction estimate. For each of the positions, the following information is indicated - serial number, code, name of the vehicle (device, mechanism), measurement unit, number of units for operation, required number of equipment to perform the work, cost of the position, and so on.
• Total costs according to estimate documentation. A separate column indicates the size of the salary fund, the price of the materials used and the costs of using mechanisms and devices.
• Various coefficients, allowances, discounts, overhead costs, as well as other parameters that are calculated as a certain percentage of the total amount for the estimate.
• The VAT amount is a parameter that is calculated from the final parameters of the estimate documentation, taking into account additional information.

The estimate also indicates the total amount of the estimate, the full name and signature of the compiler and the inspecting party. These sections are usually sufficient to obtain the total costs of construction work.

How is the construction estimate calculated?

House made of timber

In order to properly invest money in the construction of a house made of timber, it is important to determine the quality of the materials used, the costs 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, and the total price of the entire volume of materials. In addition, transportation and loader costs are added to this amount.

Timber is used as the main material. When drawing up an estimate, it is important to calculate the volume of required timber, which is sold per cubic meter. meters. It is at this stage that difficulties arise. To deal with them, you should know the perimeter of the object (indicated in the technical documentation), and then multiply the resulting parameter by the height. The final number is then multiplied by the cross-sectional area. The total volume is obtained in cubic meters - this material is enough to construct the object. Next, it remains to include the number in the estimate, taking into account the market price.

An equally important stage is calculating the costs of roofing, finishing and foundation. It’s worth starting from the foundation of the building. To solve the problem, multiply the perimeter by the thickness and height of the base. As a result, volume data remains on hand. Once 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.

Calculating the roofing material is easy. Take the roof area from the project, then multiply the parameter by the cost per square meter of the selected material. It is more difficult to calculate the costs of finishing, because different types of materials are used here. When calculating, the cost of the wall is multiplied by the price per square meter of each material separately. After completing the calculations, all that remains is to combine the costs and summarize the results.

Estimate for the construction of a frame building

Calculation of costs during the construction of a frame building occurs according to the same principle as discussed above. The difference lies in the material used. To perform calculations, it is worth having information on the shape and size of the structure at hand. It is also worth considering the costs of roofing, finishing and installation of the foundation. The estimate includes transportation and loading costs. An important point is the 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

To accurately calculate the estimate, it is worth determining the material that will be used during 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 meters or more, then the total price of aerated concrete will be from 30 thousand rubles.

Sample

To make it easier to draw up estimates for construction, it is important to have a ready-made sample document before your eyes.

The estimate is part of the working documentation. It is necessary for any construction, any work. The estimate determines how much money the construction requires. How many of them are needed to complete the work? In the article we tried to tell how the estimate is filled out, where to get the data for this? What are indices and coefficients? What does the estimated cost consist of? Everything is not as difficult as it seems.

How can this article help?

This article will help you understand the issue a little. Understand budgets at a basic level. Here are only general concepts about the composition of the estimate, examples of estimates for installation. A little about indices and coefficients. Details on the preparation of estimates for are discussed in MDS 81-35. 2001.

Title page

Let's look at how to read estimates using an example. The estimate for installation of a split system (table in the figure below) contains 13 columns. There are other types of forms, differing in the number of columns. But the principle is similar everywhere and the information in the columns is similar. The numbers of the text positions below correspond to the numbers in the picture of the estimate example. An example of an installation estimate was compiled for this article and is not tied to any specific object.

1. At the top left there is a block - “Agreed”. It specifies the contractor. The one who does the work. The organization and information of the manager are indicated. His signature and seal are also placed here.

2. At the top right there is a block - “I approve”, containing the position, surname, initials and signature of the customer’s manager. The “I approve” block is also stamped.

3. Name of the construction site - place of work. Several parts of work can be combined in one construction project.

4. Estimate number. According to regulatory documents, the following numbering order is adopted:

• the first 2 digits are the section number of the consolidated estimate;
• the second and third are the line number in its section;
• the third and fourth are the estimate number in this object estimate.

In the example, the estimate number is not included. It is not included in any documentation.

5. Name of the object, work and costs. Description of work indicating the name and address of the object.

6. Base. On what basis was the estimate formed? This could be a drawing, technical specification. We indicate, for example, technical specifications.

7. Estimated cost of work. The amount of the estimate for installation work is stated in thousands of rubles. Indication of the amount in thousands of rubles is regulated by MDS 81-35.2001.

8. Funds for wages. How much should workers be paid, theoretically?

9. Standard labor intensity. The amount of man-hours excluding downtime required to complete the work.

10. Justification of the estimated cost. The example estimate is compiled in current (forecast) prices for the first quarter of 2018 (but there may be monthly indexation). All prices are recorded in 2001 prices, and then using coefficients they are converted to prices of the current period. This method is called the basis-index method.

The tabular part of the estimate is an example of an estimate for installing a split system

The estimate header includes the following columns:

1. Quote number.

2. Code and standard number. Indicates in what standards the estimate was drawn up and under what order this regulatory framework is in effect. In this case, the FER directory (federal unit construction prices) is used. The numbers in the name of the price mean the numbers: collection - section - price table.

3. Name of work, costs and unit of pricing. The work itself is described (just as it is stated in the price), the price meter (in this case, 1 split system). Further, the coefficients for positions and position indices are written in the name of the price.

4. Quantity. The quantity is entered taking into account the pricing meter. In this example, this is one split system.

Unit cost (block 1). This block includes the current base price and its elements.

5. Total/wages.

6. Operation of machines/including wages (drivers).

7. Materials.

Total cost (block 2). It is obtained by multiplying the unit cost by the quantity.

9. Remuneration.

10. Operation of machines/including wages (drivers).

11. Materials.

Labor costs of workers (block 3) not related to machine maintenance, people. hour.

12. Per unit.

There is also a breakdown of the estimate into sections. There are no strict rules. They break it down logically. The section is always summed up.

What do the numbers in the estimate table mean?

The method of drawing up the estimate under consideration is base-index. Prices in it are indicated at the 2001 price level and are called basic. To convert prices to current levels, the base price is multiplied by the index. Direct prices cannot be immediately converted to the current price level, since there is no index for them. There are indices for cost elements. The estimate is prepared in cost elements.

There are four in total:

• workers' compensation - wages;
• operation of machines - EM;
• remuneration for drivers - ZPM;
• Cost of materials.

Where to look for direct costs in the table:

Where to look for cost elements in the table:

As in the FER standard 20-06-018-04, cost elements are prescribed. Here you can see which materials were included in the price and which remained unaccounted for.

Therefore, to find out the real price of the work, you need to multiply the prices of the cost elements in 2001 by indices and sum them up. If the “Materials” column is filled in the price, this means that the price unit contains this amount of materials. This can be seen in the example of the price for installing a split system (line No. 1). There are materials that are not included in the price. Then they are called unaccounted for and are entered in a separate line (positions 3 to 9 of this estimate).

Estimated coefficients

In addition to indices, there are coefficients. They are charged on elements of unit prices. Indicated in column 3. The coefficients may be different (for wooden structures, for excavation work, for dismantling, for work in winter conditions...). All of them can be found in magazines, collections of prices and in MDS 81-35.2001. Coefficients are calculated on the elements of unit prices. They can be either decreasing (for example, for dismantling) or increasing (for example, tightness).

At the end of the estimate, all costs are summed up. In this option for filling out the estimate, the cost line first appears in 2001 prices. Then a line with current prices, where all price indices are taken into account. Then comes the column - “Labor costs”.

Next two lines:

• SP (estimated profit).
• HP (overhead).

The coefficients for them are indicated in the prices. More information about the calculation of SP can be found in MDS 81-25.2001, and about the calculation of NR - from MDS 81-33.2004.

Afterwards, the “Total” section is divided into cost elements.

Unforeseen expenses are being accrued.

If there are sections in the estimate, then the totals of the estimate are made up of the totals of the sections.

At the end, signatures are placed and decrypted:

Compiled by (engineer full name).

Checked by (engineer full name).

Local estimate, or local estimate calculation– a form of primary estimate documentation, which is a detailed deciphered calculation of the volume of work and costs that have not been definitively determined and are subject to clarification.

In local estimates, as a rule, data is always grouped into sections by individual structural elements of a building or structure, as well as by type of work. The order of this grouping is regulated by regulatory documents. It is interesting that when drawing up such documentation for the construction or design of buildings and structures, a division of work according to the principle of underground/above-ground work may be allowed. Local estimate calculations are used in other Federal laws.

Sample local estimate and its explanation

Actually, there are a huge number of examples of local estimates. You can use one of them - this is a standard calculation for the preparation of elevator units.

It was compiled in the “Estimate Calculator” program, as evidenced by the markings in the upper left corner of the document.

As you can see, getting a sample is very easy. But often when receiving it (for example, downloading it from an auction), another question arises: how to read a local estimate? And in particular, how to read such an estimate compiled in a program designed for preparing estimates? After all, the local calculation seems to be specially designed in such a way that the reader cannot understand or calculate anything! Of course, it’s good to present such paper to an inattentive customer who will not try to delve into all these “ZP”, “EM”, etc., but will simply pay the bill. But what if you have to work on such a document yourself? You will definitely have to delve into this!

In fact, deciphering a local estimate compiled in the “Estimate Calculator” or another similar program is not such a difficult thing, although it is quite tedious. Let's try to work on it.

So, if you have already downloaded a sample local estimate, you can notice the following: the top of the document contains all sorts of introductory information (document number, who compiled it, what kind of work, the basis for compilation, etc., this is all clear and does not require explanation) . In the right corner, the following are usually indicated: the estimated cost (see “”), standard labor intensity and the salary of the main workers.

Standard labor intensity and wages of key workers

Standard labor intensity– these are the labor costs of workers (in man-hours), determined by the estimate for performing the relevant construction, repair and construction, commissioning, installation and other work.

Salary of main workers– wages of the main workers performing direct technological operations. This does not include remuneration for engineering and technical employees, bonuses and other payments.

This item has the largest discrepancies with actual labor costs. For example, in this sample the salary is worth the amount just over 3000 rubles(for all work in the estimate). For this money, at best, we will be able to hire one plumber, Uncle Vasya, and his assistant for one shift. As a rule, under government orders, wages are set at rates of about 1 - 1.2 thousand rubles for an 8-hour shift, whether it be a plumber, a loader or a vegetable cleaner. Therefore, hiring migrant workers for any work is more of a forced measure than a mandatory one.

Naturally, such an amount of work will definitely not be done in one shift (note that if you are a pure performer, and the contractor offers you a salary for the work no more than that indicated in the state local estimate, like honestly showing the estimate and throwing up your hands, you can send him away). Therefore, before playing at an auction, or simply agreeing to work according to this estimate, you need to calculate for yourself how much the real payment and standard labor intensity are indicated in it, and what the actual values ​​will be. And in order to calculate this, you need to a) estimate how much all this can actually be done; b) add a couple more days to be on the safe side. If in this situation everything looks real, you can continue to study the local estimate.

Building materials and prices for them

In local estimates, prices for materials are determined by databases that are often not indexed for years. Therefore, some waterproof plywood, indicated in the estimate at a price of 14 thousand rubles per cubic meter, actually costs 38 thousand, and you won’t find it cheaper. This time.

Two. Most often, very, very large units of measurement are indicated in the estimate. Let me explain: the price for PF-115 enamel or NTs-233 paint is indicated as per ton. Example:

Units of measurement – ​​tons (t); number of units - 0.001486 tons, that is, 1.486 kg; unit cost – 78,538 rubles 91 kopecks; and the total cost is 116 rubles 71 kopecks (cost per unit is 78,538 rubles 91 kopecks multiplied by the number of units - 0.001486). Great. According to the estimate, one and a half kilograms of colored enamel PF-115 costs us less than 117 rubles. In reality, it will cost us from 120 to 200 rubles, not counting delivery costs. It’s a small thing, but it’s nice - in this case, the estimated cost is quite the same as the actual cost, but there can be a difference of 20, 30 and even 80%, and the volumes are larger.

Decoding local estimate tables

Everything is simple here: each estimate has numbered cells in which what is in the columns is written. The numbering goes on to each sheet, and the signatures, unfortunately, remain only on the first sheet. This is very inconvenient, but usually no one does them any other way.

Accordingly, we combine the “signed” table cells with the numbers in the columns, and get the result. For example, point 2 – “Dismantling of elevators”:

The first column – everything is clear. The second column is TERr 65-27-1 (if we look at the top row, we will see that this is the “Standard Code”, or, more simply, the designation of the database from which the prices were taken). The third column is the name of the work/materials with all sorts of incomprehensible additions. The fourth column is the unit of measurement. We have one in this case is 100 pieces. The next column is the number of units. Accordingly, if the unit of measurement is 100 pieces, and the number of such units is 0.01, then in reality we have in the estimate indicated 1 piece. That is, one elevator needs to be dismantled.

Next we have the “Unit Cost” column, divided into two cells: “TOTAL/basic wages” and “Operation of machines/including wages of drivers.” Let's call it "Column A". Accordingly, in the first cell we have the same amount indicated through a fraction (that is, only the main workers are used to dismantle the elevator, without other expenses). No cars or drivers are required, therefore zeros. This is where our columns end (they didn’t fit), so let’s move on:

The next column, “Total Cost,” is divided into three cells. Let's call it “Column B”. It is not difficult to guess that “Column A” considered the cost per unit, and “Column B” considers the cost per number of units. So the cost units according to our local estimate is 1052 rubles and 68 kopecks. And, if we have 100 units per unit, and the number of units is 0.01, then the cost per number of units will be equal to 1052.68 x 0.01 = 10.52 rubles. But in the salary column it costs 128.56 rubles - where does it come from? Maybe there is a mistake in the estimate?

And from there, if you look at the first picture and study the third column, you will see in it the note “Dismantling of elevators number: 1-5 Indices: workers' salary: 12.213, to materials: 10.908, (N.R. 74*0.85 = 63% = 80.99 rubles. S.P. 50*0.8 = 40% = 51.42 rubles).” Accordingly, if we multiply our 10.52 rubles by this index 12.213, then we will get exactly the required 128 rubles. Columns 11 and 12 do not seem to raise any questions.

Any local estimate is divided into sections (except for cases where there is only one section). For each section, a subtotal is summed up, and at the end of the estimate, a total is summed up. Thanks to this, estimates are easier to decipher and estimate the costs of individual types of work and materials.

Sometimes municipalities are wrong, putting in incorrect coefficients in calculations - this also needs to be monitored. There was a case when the estimate was 1.4 kg. paint, but in fact it was necessary to use 14 kg, since they simply “forgot” to put the index. If the error is not significant for you, then you can try to tender or take on the object for work. If it is significant, it is better not to take such an object, since the overconsumption of materials (if it occurred through the fault of the estimate preparer) will be very difficult to challenge and compensate, and sometimes even impossible. Arbitration can drag on for years, and compensation will be meager.

What to do if the local estimate contains empty tables

It happens that you download auction documentation, and you come across an estimate with empty tables, or even no tables at all. What does it mean? Most likely, this means that this auction is being done “for our own people,” and therefore the estimate was removed intentionally. Orders up to 100 thousand can easily be completed by local building workers or plumbers from housing and communal services for little money.

Accordingly, everything is being done to ensure that as few “left-wing” people as possible get involved in the tender, or better yet, that there are none at all. You can also check the documents on zakupki.gov - sometimes they are there if they are not posted on other sites. It is better not to submit bids for an auction without an estimate or technical specifications, since it is not known what and in what quantity needs to be done there. However, you can submit request for clarification of auction documentation- It is your right.

Well, that's probably all. The material turned out to be quite voluminous, but it was not possible to pack it more tightly. I hope I clearly explained how a local estimate is read, how to use it, and how to understand what and how much it costs. You should always carefully study such documents, especially those with many positions, since they are full of all sorts of indices, coefficients and other amendments, which are very easy to get confused in.

Drawing up estimates for construction work is mandatory, since almost every project has a budget that needs approval. In the article we will talk about the basic principles of developing construction estimates and how the Business.Ru service will help in drawing up estimates.

What you will learn about:

Basic principles of budgeting

Any estimate is made to have a plan for completing a specific project, but also solves other problems. For example, drawing up estimates for construction and other repair work is necessary to:

• separate the money needed for various materials, procedures and work;
• understand and tell the customer how much construction will cost;
• manage cash flows evenly and correctly, in accordance with time and requirements;
• check the financial feasibility of a particular design.

The construction estimate shows the cost of materials and work that are necessary for each of the processes separately.

Traditionally, the estimate is an annex to the contract for the provision of construction services.

The functionality for preparing estimates is one of the new products of the Business.Ru service. This is useful for entrepreneurs and system users who are engaged in construction or finishing work professionally. Also, the ability to draw up construction estimates will simplify communication with contractors for store owners who delve into the process of repairing their facilities.

The principles for drawing up estimates are prescribed in the special guide “Methodology for determining the cost of construction products on the territory of the Russian Federation” MDS 81-35-2004.

According to him, there are several types of estimates. Basically, the document defines estimates when working with government orders and official bodies.

Types of construction estimates

MDS 81-35-2004 identifies the following types of construction estimates:

• local estimates (primary documents for the construction of large objects and structures: buildings, roads, etc. at a basic price level and with a forecast);
• object estimates (documents with figures from local estimates, compiled with prices of the current year);
• summary estimates (created on the basis of previous documents, as well as on the basis of the expected costs of operating the administrative apparatus). They determine the final limit of funds that will be required for the construction of objects.

Important! Methodological recommendations are necessary for professional estimators for large government orders or construction companies. When preparing such estimates, they usually use directories with prices for 2000, and then change them using a coefficient.

If we are talking about small companies when working with private companies or individuals, then a simpler version of the estimate is drawn up. The type of such document differs according to the areas of construction: a general estimate for construction work, as well as an estimate for finishing, electrical, design, plumbing, roofing, installation and other types of work.

An estimate for construction work is necessary if there is a global project ahead: from the construction of a new building to the addition of a new premises.

The sample estimate for construction work differs from other estimates in a large number of positions. For example, it may indicate not only a list of installation, but also dismantling work.

A sample estimate for construction work looks like this:

You can create a sample estimate for construction work yourself in an Excel spreadsheet, or you can use special services for preparing estimates. For example, this functionality is available in the cloud accounting system Business.Ru.

Based on the results of work in the service, the finished estimate is also uploaded to Excel, where it can be further corrected.

Electrical installation work is the whole range of repair work related to electrical wiring. These include complete and partial replacement of electrical wiring, electrical wiring in a new building, and even installation of an electrical panel, sockets and lamps.

The peculiarity of such a document is that the basis of the estimate is a list of works with costs. You can make an estimate for electrical installation work using the Business.Ru service.

Example of an estimate for electrical installation work:

After the contract between the contractor and the customer, a store with electrical equipment is selected where the purchase will be made (or the equipment is purchased by the client himself through the online store).

Design work is the first stage in the construction of a building. When designing a structure, the estimate takes into account the remuneration of specialists. Typically, estimates for design work are drawn up using special reference books where wages and coefficients are calculated. Such a document has a small number of columns.

Example of an estimate for design work:

The estimate for repair work can be very diverse. It includes sections related to finishing or minor repairs.

An example of an estimate for repair work to level the walls in a room where radiators were already installed:

Plumbing work is a group of works related to the installation and replacement of water and sewer pipes, as well as the installation and dismantling of washbasins, toilets, taps, radiators, etc.

Small private companies and individual entrepreneurs make estimates for plumbing work without taking into account guidelines for remuneration.

A sample estimate for plumbing work is presented below:

As is the case with the general estimate for construction work, the estimate for roofing work usually includes not only installation, but also dismantling work.

The picture shows a sample estimate for roofing work in an administrative building:

Welding work is usually prepared as a separate estimate only by professional estimators in large construction companies, taking into account methodological recommendations.

However, if minor welding work is performed, then the estimate for welding work can be performed in simpler programs for preparing documents. For example, in the cloud service “Business.Ru”.

Sample fragment of an estimate for welding work:

If work is carried out with excavation of soil or, conversely, backfilling it (into holes), such work is called earthwork.

The estimate for excavation work usually includes the cost of the work itself (wages for workers and foreman), as well as consumables: shovels, bags, etc.

This is what a fragment of a sample estimate for earthworks looks like, made according to methodological recommendations:

Dismantling work is a set of works associated with the destruction of a building or part of it (for example, walls, windows, doors, etc.).

Typically, in such a document, in addition to the cost of dismantling work, the fee for removing garbage from the floor, collecting and removing garbage to a landfill is indicated.

Sample estimate for dismantling work:

Installation work is a set of works related to the installation of something. The estimate for installation work includes calculation of the price of the equipment, as well as the cost of its installation.

In the Business.Ru program, you can create a similar estimate that will help sell a set of goods for the installation of technically complex products. For example, when implementing smart home systems or an electronic barrier.

By the way, a sample estimate for barrier installation work, which a store could print for a client, is presented below:

Commissioning works - a set of works after installation of equipment: checking and adjusting all processes. Typically, estimates for commissioning are drawn up in large construction companies, taking into account the codes and positions of the standards specified in special reference books.

Sample estimate for commissioning work:

Finishing work is the final stage of repair. For example, work on wallpapering, laying laminate flooring, installing doors, etc.

A sample estimate for finishing work in one of the office rooms is presented below. It includes finishing of the ceiling, walls and floor.

Estimate for work and materials

An estimate for work and materials is a simplified type of estimate that is used for minor repairs. For example, if your store just needs to paint the walls, the sample labor and materials estimate will only include the cost of paint and refinishing.

Estimate for survey work

Survey work is a list of works necessary to explore the construction site. The survey estimate includes both economic and technical work.

Economic calculations include studies that substantiate the benefits of constructing a building in this particular location. Technical is a set of matters in the field of geology and geodesy, which are also carried out before construction.

The sample estimate for survey work mainly includes costs for salaries, as well as for the delivery of specialists to the site of the proposed construction (gasoline, car rental, etc.).

The concept of estimated cost in construction

Determining the estimated cost is used not only by estimators, but also by all foremen who draw up estimates without taking into account standards. In the most general sense, the estimated cost is the amount of money intended for construction. It represents the final amount on which the contractor and the customer rely to determine the amount of financing.

When deriving the estimated cost, prices for construction goods, costs for equipment (rent, purchase), removal and delivery, and wage costs for workers and their supervisor are taken into account.

The estimated cost is determined by direct and overhead costs, as well as the estimated profit of the organization.

Direct costs include the cost of materials, operation of machinery and mechanisms, as well as wages of employees.

Overhead costs in construction estimates are indirect cash costs that are associated with the organization of work. These include, for example, remuneration for the administrative apparatus, payment for the use of programs for drawing up estimates and other documentation, the use of mobile communications, rental of administrative premises, etc.

Estimated profit is money to cover the costs of contractors and stimulate the work of workers (for example, bonuses for overtime).

Top 5 mistakes when drawing up estimates

When preparing construction estimates, errors periodically occur. Here are the top 5 most common mistakes.

1. No budget at all. The customer meets with the foreman and finds out the prices for the work in words. The contractor was recommended by a friend, so the future client does not doubt his honesty and simply inquires about the prices in order to estimate the costs.

As a result, the amount of construction or repair costs exceeds all permissible limits. After all, if there is no specific agreement on materials, the contractor will buy more construction materials than required.

1. There is no scope of work. The construction estimate may simply indicate the amount of costs for a particular action (for example, repairing a utility room), but does not indicate the scope of work.

As a result, it turns out that when drawing up the estimate, the contractor indicated only the main work on this object, and forgot additional, smaller ones (on purpose or by accident - it doesn’t matter in this case). The client has to pay extra.

For example, in a store the ceiling is being leveled. The contractor decided to use mesh and a minimal layer of plaster. But during the removal of the old coating, very large joints between the slabs are discovered, which requires 5 times more plaster consumption. The client's repair costs are rising.

1. Additional work in the estimate. This error may be accidental or special. Sometimes non-professional builders do not know about simpler technology and assume a more complex set of works. Additional work may appear in the estimate intentionally in order to increase the cost of labor.
2. Exceeding the quantity of materials in the estimate. Overestimating the amount of materials by more than 15% of what is required is not the contractor's insurance, but a mistake. After all, in order to make a good construction estimate, for example, for the renovation of a store, you need to measure all the walls, windows, doorways, check the unevenness of surfaces, etc. However, rarely does a contractor approach calculations so thoroughly.
3. Not all work is included in the estimate. An unscrupulous contractor may devote the bulk of the estimate to preparatory work. The customer, without fully considering the estimate, but only seeing the final amount, sees that the price suits him, and signs the contract.

As a result, the contractor does the rough work and disappears. The customer, having carefully looked at the estimate, sees that he really only paid for the preparatory part. As a result, such an “error” in the construction estimate leads to overpayment.
