Format of estimate for construction work. Estimate for work - sample, form and example of preparation. Form and sample estimate for work
Instructions
To create an estimate, it is best to use Microsoft Excel. It has a very convenient interface that will help you not only calculate the total amount, but also add or subtract certain columns, or replace one value with another.
Holding down the left button of the computer mouse, count six columns to the right (up to cell F1). The number of lines must correspond to the number of items that are included in the estimate.
Now write in columns. The first is the number in order. To designate it, use No. The second is the name. For example, when calculating here should be listed. The third is the cost per unit of goods (price for 1 piece). The fourth column is quantity. The symbol for this column is “quantity”. It states in numbers how many pieces of a particular item need to be taken into account.
The fifth column is the total cost. The amount for all items of the same name is entered into it. To subsequently automatically add up the total cost for all items listed in the estimate, do the following:
Use the left mouse button to select the entire column;
Click on the right mouse button to display a table with actions;
Select "Format Cells";
There, click on the first tab “Number”;
Select the format "Numeric" or "Currency".
Now, after filling out all the cells, you can calculate the total amount. To do this, select the entire column and find the designation Σ (sigma) in the upper right corner. Click on this icon to add up all the numbers in the desired column.
The sixth column is "Notes". All additional information is written here. Where to buy the necessary items, what color they will be, delivery times, etc. To ensure the text displays correctly, do the following:
Select all rows of the sixth column with the left mouse button;
Click on the right mouse button to display a table with actions;
Select "Format Cells";
Click on the first tab “Number”;
Select the "Text" format.

- Estimate for design work
An estimate is a document that takes into account the materials needed to carry out the work, their quantity and cost. The cost estimate may also include the cost of working with these materials if you order their execution from a third party. The estimate can be drawn up as a standard package of documents for each type of material and work with it, or it can be made in the form of a calculation of costs and resources per unit of material. The estimate is the basis for determining costs and capital investments.
Instructions
When drawing up an estimate for an object, start by drawing up local estimates for individual types of work. Local estimates are based on approved prices or negotiated prices. The local estimate indicates the materials required for each type of work, the cost and the estimated need for them. The final estimate for an object takes into account all local estimates and provides a calculation of the cost of the entire object.
In the summary estimate, provide aggregated and generalized indicators, take into account certain types of costs - for the purchase of construction equipment, finishing work, the cost of paint and varnish materials, preparation of a package for the land plot, reimbursement of costs for clearing the site and demolishing buildings and structures.
To draw up an estimate, in addition to the special construction education needed to estimate the composition and volume of work, the quantity and range of building materials, you will need Excel spreadsheets or special programs for drawing up estimates. You can find them at , many of them are free. The databases that are built into this special software already contain the main types of work, their costs, building materials and their consumption rates, etc. It is possible to correct data and enter new information.
If the construction project is large, it is better to divide the estimate into stages, which will be paid separately as they are completed. Include overhead costs in the estimate, which include the maintenance of the administrative level of the contractor's company and the cost of transporting construction materials. Take into account the interest on additional costs that are difficult to foresee right away.
Take into account all the costs of implementing this project in the estimate, calculate the required funds, determine the cost of labor, and calculate the costs of building materials.

Local estimate is the primary estimate document. They are compiled for individual types of work and costs for each construction project: buildings, structures, general site works. The basis for calculating the local estimate is the volume of work and necessary materials, which are determined during the development of working documentation and drawings.
Instructions
The costs that are taken into account in the local budget are divided into four groups: construction, installation work, cost of equipment, and other costs. Based on the working documentation, determine the upcoming scope of work, the nomenclature and quantity of necessary tools, inventory, equipment and furniture. Select estimated standards in force for the current period and take into account the market value of equipment, furniture, inventory and free prices and tariffs for construction and finishing materials.
Determine the type of work for which an estimate will be drawn up: special, internal sanitary and technical work, finishing work, internal electrical work, vertical planning, purchase of tools and equipment, etc. If the object is complex and large, the construction of which is divided into launch complexes, several local schemes can be carried out for the same type of work.
In each local estimate, group the data into sections by individual elements of the structure, type of work and devices in accordance with the technological sequence of work. In addition to construction work, the sections reflect work on laying communications, gas supply, ventilation and air conditioning, electrical installation work, instrumentation and automation, purchase and installation of process equipment. It is allowed to divide the object into underground and above-ground parts.
In your local estimate, consider direct costs, overhead, and estimated profit. In direct costs, include wages of employees, the cost of operating equipment, the cost of materials with line-by-line decoding. Accrue overhead costs and estimated profit at the end of the estimate, after the total amount of direct costs. To calculate overhead costs, use the overhead rates provided for in the governing documents in force for the current period.
To determine the upcoming costs of building a new house or renovating an apartment, a cost estimate is drawn up. Its cost directly depends on the quantity and quality of construction and finishing work and materials. A truly competent estimate and as close to reality as possible can be made by a professional estimator or a construction company that claims to be a contractor. But you can try to make an estimate yourself.
Instructions
Determine expenses based on the volume of work to be done. In the estimate, reflect not only the cost of materials, but also the wages of builders, depreciation of the equipment used, machinery and equipment. Take the initial data necessary for this from the current SNiPs - approved building codes and regulations. They allocate a certain number of hours to perform each type of work; accordingly, calculate the cost of one hour of time. Determine the amount of overhead costs - wages and the percentage of estimated profit. The cost of materials according to the estimate is 65-70%, 17% is wages, the remaining amount includes the cost of equipment, maintenance of the apparatus and unforeseen expenses.
When compiling, at the initial stage, try to take into account all the nuances in order to avoid. For example, when building a certain type of house, a specific foundation height is specified. It is necessary that the zero level is determined correctly so that the foundation does not turn out to be too high or low. Take into account the climatic zone of construction - in the northern regions, communications are laid deeper so that they do not freeze in winter.
See what you can save on. There can be a significant difference when using different building materials - if, for example, instead of brick, wood is used to build external walls. In addition, domestic building materials are also cheaper, although their quality is sometimes no worse than imported ones, since they are produced using foreign technologies.
A well-written estimate should reflect all costs by 99.9%. But keep in mind that under farcical circumstances, its cost may increase. We advise you to set aside at least 10% of the cost estimate for unforeseen expenses so that the construction of your house or apartment renovation does not turn into a long-term construction project.
Drawing up a detailed estimate is the key to successful construction. It is at the preparation stage that you need to think about how much building materials will be needed, what work will have to be done, and what should be abandoned.
Instructions
If you plan to build a house from scratch, make two estimates. One will calculate the amount of building materials, the other will calculate the cost of construction work, interior and exterior decoration and communications. If there is no water supply, sewerage, electricity or gas on the site, prepare a third calculation, which will indicate the price for their connection.
Use Microsoft Excel to create estimates. Its convenient interface will help you calculate the total amount of costs, multiply or subtract individual columns, and replace one value with another.
To spreadsheets for estimates, hover over the top left cell. Its symbol in the program is A1. Press the left button on your computer mouse. Moving the cursor to the right, count six columns (to cell F1). Make as many lines as there are items or services in the estimate.
Name the columns. The first is the serial number. Designate it with the symbol No. The next one is the name (name or services). For example, when calculating construction there should be a list of materials. And when conducting communications - types of work. The third is the price per item or service. Next comes the “quantity” or “quantity” column. Write down here in numbers how many products or services will be needed to complete the repair or construction of a house.
Column number five is the total cost. Enter here the amount for all products or works of the same name. To have the total price added up automatically, do the following:
Press the right button so that a window with actions appears;
Find "Format Cells";
Specify "Number" or "Currency" format.
Now, having filled in all the cells, you can display the total amount. Just select the entire column and look in the upper corner, on the right, for the Σ (sigma) icon. Click on it to sum up all the values in the desired column or row.
Place your notes in the sixth column. Record any additional information here. Where to buy the necessary materials, their size, color, etc. Within what time frame must the work be completed? To ensure the text displays correctly, do the following:
Select the entire column by hovering the mouse cursor over the top cell and holding down the left button;
Click on the right button so that a window with actions appears;
Find "Format Cells";
Open the first tab "Number";
Specify "Text" format.

- how to make a commercial estimate
Drawing up an estimate is one of the first and main stages of all construction and installation work. It represents the calculation of the cost of construction, finishing and repair work according to the approved design documentation, taking into account actual volumes. The estimate allows you to estimate their cost even before the start of work and adjust it by changing the technologies and the construction and finishing materials used.
Instructions
When preparing estimates, a developed and agreed upon methodological and costing base is used. Its basis is the documents developed by the State Construction Committee of Russia: a set of rules, guidelines and methodological documents. These regulatory developments use prices as of January 1, 2000, which are adjusted to modern prices using adjustment factors that take into account inflation.
When drawing up estimates, use the methodology introduced on March 9, 2004 (MDS 81-1.99) and other MDS and guidelines of the State Construction Committee of the Russian Federation. These regulations provide general information about the pricing process in construction and provisions for determining its cost.
MDS 81-1.99, the main state methodological document, provides recommended coefficients that take into account the influence of work conditions. In addition, in it you can find unified estimate documentation and a breakdown of the main types of work that are classified as others.
Include in the total estimated cost the costs of construction (repair and construction) work, the cost of installation work, the cost of used equipment and inventory, and other costs. As a rule, construction and installation works account for about 46-48% of the total cost of the estimate, the cost of equipment - 35-36%, other costs - 17-18%.
Checking the provided estimate is carried out not only to determine the correctness of the calculations given, it is necessary to control quality and find opportunities to replace expensive work and materials with more economically profitable ones.
When analyzing and checking the estimate, in order to insure against fraud, first of all, pay attention to compliance with the actual volume of work and consumption standards for construction and finishing materials. Please note that direct costs are directly related to the amount of work performed, the necessary resources, estimated standards and prices for these resources. Direct costs include costs associated with the pre-processing and preparation of certain construction materials and the costs of transporting them to the construction site. Overhead costs are determined indirectly as a percentage of the construction workers' payroll. Estimated profit is defined as a pre-agreed percentage in the composition of construction products; it mainly goes to the development of the production and social sphere of the contracting organization.

Before starting repair or construction work, each owner calculates how much money will be needed for repair or construction. To get the exact amount of costs, an estimate is drawn up, which includes all costs associated with future construction or repair work.
In the “work” column, write down each item and what kind of work will be carried out. Consider everything from preparatory work to finishing work. If workers will be involved, write down point by point what kind of work they will do. For example, scraping, painting, replacing windows, etc.
In the “materials” column, indicate the necessary materials for each stage of work. For example, wallpaper, glue, linoleum, parquet, bricks, cement, etc. After you have described these items in detail, proceed to estimate the costs for each of them. In each column opposite the building material, fill in the approximate quantity in pieces, meters, kilograms and indicate the cost of each item. Find out the cost of building materials on the Internet on special websites that specialize in selling such products.
Repair is a rather expensive undertaking, for which you have to set aside part of the family budget for some time. Since it is associated with discomfort for everyone living in the apartment, it is natural to want to do it efficiently so that the next repair will not need to be done soon. Therefore, before starting renovation work, it is important to draw up an estimate, calculate its cost and select building materials in accordance with your financial capabilities.
What is a repair estimate?
A well-drawn estimate will allow you to properly plan and organize repair work and complete it in the shortest possible time with an optimal result. If the repair is not cosmetic, requiring only finishing materials, your estimate should consist of two parts:- finishing works;
- for consumables (roughing) and finishing materials.
The purpose of drawing up an estimate is to calculate the need for materials and the actual cost of all repair work from the dismantling of old coatings to the finishing of the apartment premises. Drawing up an estimate will allow you to avoid unplanned costs, however, as experience shows, it is still advisable to set aside another 10% of the estimated cost that was calculated for them.
How to make an estimate for apartment renovation
Of course, it’s nice if you have some skills and an idea about repairs, but you can calculate the approximate costs in any case. You can use standard estimates that you find on the Internet, or based on them, make your own calculation using Excel spreadsheets. On the Internet you can find both paid and free estimating programs: Win-Estimate, Turbo Estimator, DefSmeta, etc.Inspect each room of the apartment and make a list of consumables and finishing materials that you will need. Their approximate cost can be found on the Internet, catalogs of construction hypermarkets, and price lists of manufacturing companies. Make a list of construction, repair and finishing works; their cost can be determined from the price lists of construction companies or private teams that also offer their services via the Internet. Pay attention to the units in which the amount of work is measured.
You will need to take into account the need for materials that are used for repair work, such as: primer, putty, dry plaster mixtures, adhesive for ceramic tiles, wallpaper and other coatings, plumbing pipes, mixers and taps, filters, wires, sockets, switches, screws, nails, laminate underlayment, etc. For finishing you will need: wallpaper, facing and ceramic tiles, floor and wall decorative coverings; laminate, linoleum or parquet boards, plasterboards, baseboards, paint, windows and interior doors, etc.
Draw a floor plan of the apartment by hand to make it easier to take measurements, use a tape measure to measure the surface area of floors, walls, etc. Calculate the required volumes of consumables. Please note that at least 5% will need to be added for marriage. Determine the scope of work and calculate its cost.
The most important stage of the project is the preparation and subsequent completion of the estimate. This is done at the final stage of preparation for its implementation. Based on the prepared financial document, a calendar plan for the implementation of the undertaking and delivery schedules for the necessary materials and equipment are drawn up. Let's look further at examples of estimates and how to draw them up correctly.
Download examples
The estimate is a financial document that includes the prices of all work performed and the necessary tools and materials. In addition, it always includes overhead costs (about 15% of the total amount), unforeseen costs (2%) and the profit of the contractor (10-15%).
Basic principles of budgeting
Usually the organization that will carry out the work handles the calculations. She must coordinate all her actions with the customer. The more detailed all processes and materials are described (down to the number and brand of screws), the better. However, often in practice a simplified version is used, where only the main types of work, units of measurement, quantities, prices and costs of processes are indicated.
An example of an estimate for renovation work on a room in an apartment in a simplified version:
| No. | Title of works | Units | Quantity | Price for 1 unit | Cost of work |
|---|---|---|---|---|---|
| 1 | Dismantling partitions | sq.m. | 50 | 350 | 17500 |
| 2 | Dismantling the balcony door | PC. | 1 | 1100 | 1100 |
| 3 | Installation of partitions (foam blocks) | sq.m. | 50 | 600 | 30000 |
| 4 | Plastering walls and partitions | sq.m. | 200 | 200 | 40000 |
| 5 | Double putty, priming and painting of prepared surfaces | sq.m. | 200 | 3000 | 34000 |
| 6 | Installation of a balcony door | PC. | 1 | 270 | 3000 |
| 7 | Plastering slopes (windows and doors) | sq.m. | 16 | 250 | 4320 |
| 8 | Improvement of slopes (putty, primer, painting) | sq.m. | 16 | 4000 | |
| Total according to estimate | 133920 | ||||
This sample estimate is applicable for making calculations for small-scale projects, and the entered data, if necessary, can easily be adjusted by agreement with the customer. It does not describe exactly how many bags of putty or cans of paint are required to complete the necessary work. The parties agree on the price per unit of measurement and the total cost, and the details (purchase of materials, transportation costs, removal of construction waste) are borne by the contractor.
Let's look at an example of an estimate compiled using a different method. In this case, all the necessary resources to complete the work at each stage are outlined.
At the request of the customer, an estimator or contractor can prepare several versions of estimates, taking into account various components (brand, price and quantity of materials, scope of work, quantity and technical indicators of equipment used, number of workers).
In what form are estimate documents drawn up?
For different types of work, different forms of drawing up financial documents are used. Let us pay attention to an example of an estimate for design and survey work (design and survey work), which is drawn up in accordance with form 3p. It is an annex to the contract between the parties, the cost here is determined by labor costs. Form 3p estimate is used to calculate the cost of research, design, environmental engineering, engineering and survey work. 
Often such estimates consist of two tables. In the first, the level of labor costs is determined, and in the second, the cost of the work performed is calculated. The cost of work is proportional to the time spent on all processes and the remuneration of designers. The second table may also include other costs, such as depreciation, freight and travel costs, and material costs.
For construction work, other forms of estimates are provided:
- Local is prepared for a specific type of work performed; it takes into account the costs of individual sections of construction or repair work.
- The object one is formed within the framework of one object, combining all local estimates and their calculations related to this object. Its adjustment is made based on the data from the working documentation.
- The summary estimate is based on site estimates and characterizes the total final cost of constructing a structure or building.
If it is not possible to draw up an accurate estimate due to the fact that there is no complete clarity on the specification of the materials used or changes will still be made to the project, then local and site-specific estimates can be drawn up. Also often used are estimates drawn up in the form KS-2 (act of acceptance of work performed) and KS-3 (certificate of costs and value of work performed).
Non-profit organizations, including budget ones, are required by law to prepare an annual budget for income and expenses.
Computer programs for financial calculations
Nowadays, many software products have been developed that can be used to prepare various financial documents. With a certain degree of convention, they can be divided into two groups:
- Free. They can be freely found on the Internet, on thematic sites. Such programs have minimal functionality, allow you to perform the simplest calculations and do not have the function of updating regulatory frameworks.
- Professional. They are used by specialists and require the purchase of a software and service product. The most popular and functional are “Smeta.ru”, “GRAND Smeta”, “1C: Contractor”, “Turbosmeta”, etc.
However, in the familiar Microsoft Excel program, you can also easily create an estimate template for the implementation of the required project.
To fill out the estimate, just insert the necessary indicators into the created form, all calculations will be carried out automatically.
If the project requires a large amount of various work and significant investments, then you should not undertake such serious calculations yourself without special knowledge. It is better to turn to specialists who are proficient in modern production technologies and the current situation in the building materials market. They will be able to give an objective picture of the expected costs and offer options for its possible optimization. By saving on the services of an estimator, you can lose more and not realize your plan at all.
Drawing up and subsequent filling out an estimate is rightfully considered the most important stage of any construction or repair work. In most cases, the design of a building or structure is completed by drawing up estimate documentation. In the case of performing small amounts of work, for example, repair or finishing, when the project is not being developed, an estimate is also necessary. This is explained by the fact that it serves as initial information for the development of many related documents necessary and important for the effective organization of work, in particular, a work schedule and a delivery schedule for the necessary materials and mechanisms.
Drawing up estimates will become a much simpler process if you entrust this task to professionals.
Form and sample estimate for work
Essentially, the document in question consists of two parts:
- calculation of direct costs, which are determined based on 2001 prices and are converted into current prices by multiplying by the corresponding price increase index, established quarterly. Direct costs consist of the following elements:
- Cost of materials;
- basic salary of workers;
- costs for EMM (operation of machines and mechanisms necessary to perform work), including salary for machinists;
- calculation of overhead costs and estimated profit, made taking into account the standards in force at the time of drawing up the estimate.
The disadvantage of this method is that the 2001 prices used when using it often do not take into account the realities of today, since at the time of compilation many technologies and materials simply did not exist. However, for the construction of budget facilities and most private large construction projects, there is no alternative to the base-index method today.

The importance of competent preparation and execution of estimates
As already noted, filling out an estimate allows you not only to get an approximate amount that construction or a certain amount of work will cost. This value is necessary to determine the contract price of an object or stage of work, both for the customer or investor, and for the contractor, that is, the direct manufacturer.
But in addition to this direct functional purpose, a competent and modeled estimate will allow you to plan the work in such a way that it is completed as quickly as possible and at a lower cost. In addition, the estimate also helps to determine the need for the necessary materials, which, in combination with the work schedule, will allow us to develop a schedule for their delivery.
Main objectives of the estimate
Developing and filling out an estimate allows you to solve three most important tasks at once, always facing any contractor and customer:
- determining the cost of construction or carrying out any work. In modern conditions, the estimated price is the most important parameter, vital for all participants in the construction process. The customer is interested in not overpaying, and the contractor is interested in receiving a decent reward for the work. A well-prepared estimate allows you to take into account the wishes of both parties and get an amount that suits everyone;
- development of a calendar plan. The timing of the construction of a building or the completion of any work is often no less important to the customer than its cost. The timely delivery of the object and, naturally, the receipt of remuneration, possibly with a bonus, depend on this. An estimate for work, made according to the sample, provides builders with all the necessary information to develop a schedule;
- development of a materials supply schedule. When the estimate is filled out correctly, the need for materials and mechanisms becomes clear, which, in combination with the calendar plan, makes it possible to draw up another document that is important for the smooth work of builders - a materials supply schedule. Effectively operating construction organizations do not purchase materials for the entire project at once - this simply freezes money that could be much more efficiently spent on something more important at the moment, and also requires significant costs for warehousing, etc. Also, any downtime of equipment and workers is extremely unprofitable, which is fraught with equally serious additional costs.
As a result, we can say the following: drawing up an estimate allows you not only to understand the cost of construction or a separate stage of work, but also to effectively plan their implementation.
Base-index method of drawing up and filling out estimates
There are several different methods for generating estimated costs. When constructing large objects, when filling out estimates takes place as part of project development, the base-index method is almost always used. In this case, the estimate standards of 2001 and conversion indices to current prices are used for calculations.
Simplified estimate form
Quite often, especially when construction or repairs are carried out on a self-employed basis or on small projects, a simpler estimate form is used, which consists only of calculating direct costs. It contains a list of the scope of work and prices for them, which can be divided into the same components as in the version described above: salary of workers, cost of materials and, if necessary, costs of machinery and mechanisms. In this case, the estimate form, after it has been completed and filled out, will look as shown in the following photo:
When drawing up and filling out such a simplified version of the estimate, the contractor’s profit is established on the basis of his negotiations with the customer or construction investor.
Form of object estimate for work performance
Quite often, especially when constructing large objects, several so-called local estimates are drawn up at once, that is, separate calculations for each type of work performed. In this case, to obtain the total cost of construction, they are combined into a general object estimate, a sample form of which is shown in the following photo.
Object estimate
Drawing up and filling out a project estimate allows you to bring together all the information about the facility under construction, even when individual stages of its construction are carried out by different contractors. Often local estimates are also calculated by them. Therefore, summarizing all the disparate data is extremely important for any customer or investor.
Programs for drawing up and filling out estimates
Currently, there are many programs that are used in preparing estimates. With some degree of convention, they can be divided into two groups:
Free. They are posted online on thematic resources. Are freely available.
Professional. Used for work by specialists. To use, you must purchase a distribution kit of the service product.
In the first case, there is no particular need to describe programs, since they appear almost constantly, having similar parameters:
- the ability to perform the simplest calculations;
- lack of updating of regulatory frameworks (if they exist at all);
- minimal functionality.
Professional estimate programs are used much more actively, since without them it is almost impossible to compile high-quality documentation for any large object. The most popular products at the moment are the following:
GRAND Estimate
According to experts, the most widely used estimate program. Its advantages are the ability to automate the entire complex of estimate work, the speed of making changes to the regulatory framework and effective technical support of the product.
Smeta.ru
The only program that really competes with the GRAND Estimate described above. The main advantage of the product is its ease of use, which allows you to work with it without having the professional knowledge of an estimator.
1C: Contractor (or 1C: Construction Organization Management)
These programs are not purely budgetary. However, they are quite popular due to the fact that 1C is used for accounting at the vast majority of Russian enterprises, including construction ones. The software products in question help to draw up the necessary estimate documentation; as a bonus, they are integrated into the company’s unified work management system.
Turbo estimator
The program is easy to learn and use, yet has quite serious functionality. It is not used as often as compared to GRAND Smeta and Smeta.ru.
WinSmeta, Rick and Bagheera
Software products whose peak popularity is in the past. However, a certain number of professional estimators still continue to use them, which is explained by a number of undoubted advantages: wide functionality, editing capabilities, adjustments, etc.
Basic mistakes when drawing up estimates
There are several main types of errors that occur when drawing up and processing estimates in practice. The most typical are the following:
Error 1. Insufficient detail or excessive enlargement of the estimate. Any well-written estimate must contain a complete list and volume of work performed and, accordingly, prices for them. In practice, often the customer and the contractor, having found out that the price level suits both parties, agree on the cost of a stage of work, for example, the renovation of one room. As a result, in fact, we get a situation where the actual amount of work performed does not coincide with what was initially expected. The result is a conflict situation, since it is not clear how to evaluate the increase or decrease in cost of work;
Error 2. Inaccurate accounting of volumes. The basis for the construction estimate must be a correctly and accurately compiled bill of quantities; in the case of repairs, a defective bill of quantities. In both situations, the result of drawing up the estimate depends on the correctness of their preparation. An error at first can lead to a fairly serious distortion of the final cost of the calculation, since in most cases multiplication occurs by various indices and prices, so the magnitude of the error increases all the time;
Error 3. Incorrect application of prices contained in GESNs and TERs. One of the main problems of the basis-index method, the most common in real life, which was mentioned above, is the discrepancy between the available types of work and those that are encountered in practice. Therefore, quite often it is necessary to use the existing prices “as applicable”. This is a special term coined by estimators for such a situation. The more “as applicable” prices are used when filling out an estimate, the more likely it is that the final figure will be incorrect. Naturally, it is worth taking into account the fact that customers try to use low “applicable” prices, and contractors, on the contrary, are the most profitable.
In any case, the preparation and execution of estimates should be considered an important and extremely necessary preparatory stage of any construction in modern conditions. It is better to entrust its implementation to professional and trained estimators, which will not only create the optimal cost of work for the customer and contractor, but also organize their effective implementation in the shortest possible time and at the lowest possible cost.
