Finishing is the final stage of repair, during which a certain list of works is performed. The result of their implementation is ready-to-use residential, administrative and industrial premises. To estimate the estimated costs, an estimate is made. It determines the volume and content of technological operations for the transformation of premises, the complexity of their implementation, the nomenclature and the amount of required materials. How to make an estimate for finishing work? To do this, you need to know the algorithm for its design and competently use the regulatory documents that govern the calculations.

Simple circuit

The easiest way to draw up an estimate for finishing work is in demand when performing repairs on your own or with the involvement of a hired team. In this case, the cost of materials is determined in accordance with the selected price segment and the average cost in the construction market and in shopping centers. The cost of finishing work is not taken into account or depends on the terms of the contract with the contractors. The calculation of the amount of necessary financial investments to complete the repair is carried out in several stages and includes the following steps:

• inspection of the premises and assessment of its condition;
• measuring the area of ​​the floor, walls and ceiling;
• selection of a room design concept, taking into account its purpose and taste preferences of property owners;
• determination of the list of works required to create the designed interior, and their cost;
• counting the amount of materials required for finishing, and determining their cost depending on prices.

When you independently transform the interior of a room, you should also include the funds spent on the purchase of tools and special devices for performing various types of repair work. In addition, it is necessary to provide for the allocation of a certain amount for cleaning the premises at the end of the finishing of the premises. Removing bulky construction waste on your own can result in a significant fine.

Determination of costs in accordance with the standards

How to make an estimate using the algorithm established by regulatory documents? Usually, its design is delegated to special organizations or the design department of a construction company, which will carry out finishing and repair work. However, you can make an estimate with your own hands, having studied special literature or using as a sample a similar document developed to restore a room similar in overall dimensions, technical condition and purpose.

At the initial stage, you should evaluate the financial capabilities of the owner of the room, taking into account the prices of materials on the construction market. Then the state of the room is determined and a list of necessary technological operations is drawn up. The preparatory work is completed by measuring the dimensions of the room with an indication of the available structural elements. Based on the data received, fill out the form of the defective statement. It reflects the slightest changes in the interior of the room and describes all the details of the transformation of the interior with the obligatory indication of the size of the changed areas.

After registration, the defective statement is agreed with the owner of the premises and, along with the contract, serves as the basis for drawing up an estimate. It is transferred to the estimate department or directly to the specialist performing the calculations.

Types of estimates and methods of calculation

On the territory of the Russian Federation, estimates can be drawn up in several ways, including:

• basic index;
• basic compensation;
• resource-index;
• resource.

In the first case, to determine the cost of services and materials, a system of forecast indices is used in relation to the base prices for works and raw materials according to the data of the previous period. The final prices are calculated on the basis of basic indicators.

When choosing a basic compensation method, the projected cost of the necessary materials and services is determined taking into account the projected tariffs. Its refinement takes place directly at the construction site. If the calculations are carried out according to the resource method, then within their framework, resource tariffs and forecast prices are calculated. In this case, the estimate for finishing work is drawn up taking into account the consumption rates of materials, which are regulated by the regulatory documentation. When using the resource-index method, the calculation according to the system of price indices is combined with the resource method.

The choice of a particular option is not regulated by law, therefore, the methodology for making estimates is determined according to the characteristics of the object. The most popular algorithms include resource-index and resource methods.

Formation of estimates

How is the estimate made? It is formed by summing up several types of costs, which are:

• straight;
• waybills;
• planned.

Direct costs represent funds for payment of materials, labor of executors carrying out finishing work and operating costs. Their calculation is based on:

• a list of technological operations to transform the interior;
• volume of work performed;
• accepted norms.

Overhead costs include the cost of organizing the process of carrying out repairs, management and maintenance. Usually their value is a certain percentage of direct costs and is calculated in accordance with established norms or according to the accounting system at the enterprise. The calculation of the estimate with the inclusion of overhead costs can be performed both for an aggregated indicator and for a separate type of work.

Planned savings include funds that cover expenses that are not directly related to construction. Among them are the costs of paying taxes, creating favorable conditions for the work of employees and stimulating their activities. Planned costs are formed on the basis of industry-wide or individual standards.

Nuances of calculations

How to make a correct estimate for finishing work in the absence of the necessary experience? You can use a suitable project as an example, making the appropriate amendments. The final figures are adjusted taking into account the number of employed specialists, their qualifications and other parameters. To simplify the preparation of estimates, special programs are also used, similar in functions to "1 C Accounting" and containing samples of all variants of estimate documentation.

The calculation of the estimated cost of converting the interior is carried out using standard estimates, special projects, established standards of the current price lists. They are tied to a specific type of work and provide the ability to vary prices, despite the outdated regulatory framework.

In particular, at the stage of preparation, if necessary, priming and filling the surfaces of walls and ceilings, the price is calculated by summing the cost of materials and the cost of performing work. Before completing the formation of the estimate, all costs are combined. Typically, the actual cost exceeds the design value by about 10-15%.

Possible shortcomings and pitfalls

If the preparation of the estimate was entrusted to a specialized organization or department of the enterprise that will carry out the repair work, then the owners of the premises can check the correctness of its calculations. The easiest way to overestimate the cost of work is to incorrectly measure the dimensions of the room and assess its condition. The increase in the number of finishing materials and complex preparatory operations significantly increase the level of repair costs.

Time-consuming preparatory work, which is easy to do without, also contributes to the increase in costs. On the other hand, saving on primer and putty can lead to the fact that over time the facing material will lose its original appearance and require replacement. In addition, inadequate surface preparation will not provide adequate adhesion and will lead to delamination of the finish.

Other ways to increase the cost of the estimate include:

• overpricing of materials;
• inclusion of works not provided for by the project;
• purchase of expensive materials without taking into account their quality and expediency of use;
• failure to provide pre-agreed discounts on payment for materials and services rendered;
• adding to the general item of expenses the cost of delivery of components, materials and tools.

Another marketing move is a significant understatement of the cost estimate at the stage of preparatory work and the signing of the contract. This method is aimed at attracting customers, for whom, as a result, after the start of the repair, it turns out to be unforeseen expenses in a significant amount. For bona fide contractors, the cost of the estimate does not change significantly throughout the entire provision of finishing services.

All of us are periodically faced with the need to renovate and decorate an apartment. First, it's worth deciding whether we just want to update the room or completely change its appearance? After that, we assess our financial capabilities. You also need to choose the style of the apartment, for this we review the photos on the website or in magazines. Style should reflect the character of the owners and demonstrate taste. We decide on the color of the walls and ceiling. The color combination should be harmonious. If possible, it is better to renovate the whole apartment. Too much debris and dirt remains after the renovation.

To draw up the main stages of repair, a general plan of the apartment with the dimensions of windows and doors is required. The procurement of materials and tools depends on how correctly the work plan is drawn up. It is necessary to determine the timing of the beginning and end of the repair so that it does not stretch out for many months.

The repair begins with the dirty robots themselves: replacing windows, removing door frames, chipping walls for electrical wiring, sockets and switches, removing old wallpaper, whitewashing, plaster. We dismantle the old tiles in the bathroom, bathroom and kitchen. After that, we dismantle the pipes, if necessary.

We start the alteration process from the bathroom and the kitchen. When renovating premises, most of all dirt and dust remains. We put tiles on the aligned walls. It cleans well and is indispensable for wet rooms. We immediately resolve the issue of replacing the bathroom, toilet and sink. Then, in turn, we repair all the rooms, starting with the farthest. Corridor repairs are done last.

The most time-consuming and monotonous type of work is putty. There are many types of starting and finishing fillers. If the walls have to be leveled a lot, then the stage of plastering is extended. A thick layer dries more slowly. For a stronger adhesion of the putty and the surface, the walls and ceiling are pre-primed. After complete drying, make a finishing putty. Smooth surfaces of walls and ceilings are the main work done correctly.

The quality of the floor of the apartment depends on the screed. You can make a classic screed from a cement-sand mortar. With the development of repair technologies, self-leveling floor leveling has also begun to be applied. If you have an apartment on the ground floor, then underfloor heating will be an excellent solution. There are many types of flooring on the market: parquet, laminate, linoleum, etc. Any of them can be laid on a flat floor.

Painting work is carried out only in the field of final drying of ceilings, walls and floor screed. After that, we carry out whitewashing or painting the ceiling. Next, we install interior partitions or doors. We pay special attention to the selection and gluing of wallpapers. Wallpaper design can support any renovation concept, and proper gluing is the basis for creating an apartment's interior. Last but not least, we install skirting boards, platbands, plumbing and decor.

We decided on the sequence of work. Now a few words about the procurement and delivery of materials. Materials are the main expense. Starting and finishing putty, primer, water-based paint and wallpaper are suitable for walls and ceilings. For the floor, you need to choose the appropriate coating and screed material. For the bathroom, kitchen, bathroom, you will need tiles, glue and fugue. The faucets in the bathroom and kitchen must be replaced. It is necessary to accurately calculate the number of wallpapers and tiles, as the color may vary from batch to batch.

If you hire a builder, then you don't have to worry about tools, they prefer to work with their accessories. We'll have to buy paint brushes and a couple of spatulas. If you are going to do apartment renovation yourself, then you should take care of the construction tool in advance. Modern materials require special tools. It is expensive to buy them, so go to the rental office.

When calculating the consumption of any material, it is necessary to find out the area on which it will be applied, and multiply this number by the consumption rate. And do not forget to add 10% to your calculations of the amount of materials. Make an estimate. If you decide to change the bathroom and toilet, add their cost to your total costs. If you forgot something, it doesn't matter. The hardware stores have everything you need. You must have a reserve of money for at least 30% of the estimated amount, because there will always be unplanned expenses during the repair process.

If you live in an apartment being repaired, then do the alteration of each room separately. You can do the repair yourself or hire a contractor, but remember that many of the above jobs require certain qualifications. If you have not done plastering before, have not screed floors or laid tiles, then it is better not to waste energy on work and money on materials. It will be cheaper to hire professionals. In any case, the double-glazed windows must be installed by a specialized company. The same applies to the front door. Be careful with the fashionable redevelopment of apartments. Do not damage the load-bearing walls.

The preparation and subsequent filling of the estimate is deservedly considered the most important stage of any construction or repair work. In most cases, the design of a building or structure is completed with the design of estimate documentation. In the case of performing small amounts of work, for example, repair or finishing work, when the project is not being developed, an estimate is also required. This is due to the fact that it serves as the initial information for the development of many related documents necessary and important for the effective organization of work, in particular, the schedule for the execution of work and the schedule for the delivery of the necessary materials and mechanisms.

Budgeting will become a much simpler process if you entrust this business to professionals.

Form and sample estimate for work

In fact, the document in question consists of two parts:

• calculation of direct costs, which are determined on the basis of 2001 prices and are converted into current prices by multiplying by the corresponding index of appreciation established on a quarterly basis. Direct costs consist of the following elements:
  • Cost of materials;
  • the main salary of workers;
  • expenses for EMM (operation of machines and mechanisms necessary for the performance of work), including salary of drivers;
  • calculation of overhead costs and estimated profit, taking into account the standards in force at the time of the estimate.

The disadvantage of this method is that the 2001 rates used when using it quite often do not take into account the realities of today, since at the time of compilation of many technologies and materials simply did not exist. However, in the construction of budgetary facilities and most private large construction projects, there is no alternative to the basic-index method today.

How to make an estimate for a job

As an example of a simplified form of estimates for the repair of a room, you can give the following table.

	Name of works			Price per unit	Cost of work
	Dismantling partitions
	Dismantling the balcony door
	Construction of partitions from foam blocks
	Plastering of partitions and walls
	Putty, primer and painting of plastered surfaces
	Installing a balcony door
	Plastering of door and window slopes
	Putty, primer and painting of window and door slopes
	TOTAL according to the estimate				139 080=

The importance of competent drawing up and execution of the estimate

As already noted, filling out the estimate allows you not only to get an approximate amount, which will cost the construction or the implementation of a certain amount of work. 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, competent and patterned design of the estimate will allow you to plan the work in such a way that they are done as quickly as possible and at a lower price. In addition, the estimate also helps to determine the need for the necessary materials, which, in combination with the schedule for the production of work, will allow you to develop a schedule for their delivery.

The main tasks of the estimate

The development and filling out of the estimate allows you to solve three most important tasks at once, always facing any contractor and customer:

• determination of 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 not to overpay, and the contractor is interested in getting a decent remuneration for the work. A competently drawn up estimate allows you to take into account the wishes of both parties and get a sum 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 for the customer than their cost. The timely delivery of the object and, of course, the receipt of remuneration, possibly with a premium, depends on this. The estimate for the work, made according to the model, provides the builders with all the necessary information to develop a schedule;
• development of a schedule for the delivery of materials. With the correct filling of the estimate, the need for materials and mechanisms becomes clear, which, in combination with the timetable, makes it possible to draw up another document, which is most important for the smooth work of builders - the schedule for the supply of materials. Effectively operating construction organizations do not purchase materials for the entire facility at once - this simply freezes money, which is much more efficient to spend on something more important at the moment, and also requires significant costs for storage, etc. Also, any downtime of equipment and workers is extremely unprofitable, which is fraught with no less serious additional costs.

As a result, we can say the following: the design of the estimate allows 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 of estimating the cost estimate. When building large objects, when the estimate is filled in as part of the development of the project, the base-index method is almost always used. In this case, the estimated standards of 2001 and the indices of conversion to current prices are used for the calculation.

Simplified estimate form

Quite often, especially when construction or repairs are carried out on a household basis or on small objects, a simpler estimate form is used, which consists only of calculating direct costs. It contains a listing of the scope of work and prices for them, which can be broken down into the same components as in the above option: salary of workers, the cost of materials and, if necessary, the cost of machines and mechanisms. In this case, the estimate form after its registration and filling out looks 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 investor of the construction.

Object estimate form for work performance

Quite often, especially when building 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 an object estimate allows you to bring together all the information about the object under construction, even when the individual stages of its construction are performed by different contractors. Often, local estimates are also calculated by them. Therefore, the generalization of all 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 the preparation of estimates. With some degree of conventionality, they can be divided into two groups:

Free. Placed on the network on thematic resources. Are freely available.

Professional. They are used for work by specialists. To use it, you need to purchase a distribution kit of a service product.

In the first case, there is no special need to describe programs, since they appear almost constantly, while having similar parameters:

• the ability to perform the simplest calculations;
• lack of updating of regulatory bases (if they are present at all);
• minimal functionality.

Professional estimate programs are used much more actively, since without them it is almost impossible to draw up high-quality documentation for any large object. The most popular products at the moment are the following:

GRAND Estimate

According to experts, the most widespread estimate program. Its advantages are the ability to automate the entire complex of estimate work, the promptness 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 the estimator.

1C: Contractor (or 1C: Management of a construction organization)

These programs are not purely estimates. However, they are quite popular due to the fact that 1C is used for accounting at the overwhelming majority of Russian enterprises, including construction ones. The considered software products help to draw up the necessary estimate documentation, as a bonus, they are integrated into a unified management system for the company's work.

Turbosmetchik

An easy-to-learn and use program with quite serious functionality. It is used not so often, in comparison with GRAND Smeta and Smeta.ru.

WinSummary, Rick and Bagheera

Software products, the peak of popularity of which 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.

The main mistakes when drawing up estimates

There are several main types of errors that are encountered in the preparation and execution of estimates in practice. The most typical are the following:

Error 1. Insufficient detailing or excessive enlargement of the estimate. Any competently drawn up estimate must necessarily contain a complete list and volume of work performed and, accordingly, prices for them. In practice, it is not uncommon for 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, repairing one room. As a result, in fact, a situation is obtained when the actually performed volume of any work does not coincide with the initially anticipated one. The result is a conflict situation, since it is not clear how to assess the rise in price or reduction in the cost of work;

Mistake 2. Inaccurate accounting of volumes. The basis for the construction estimate must necessarily be a competently and accurately compiled statement of volumes, in case of repair - a defective statement. In both situations, the result of budgeting depends on the correctness of their preparation. An error at the beginning can lead to a rather serious distortion of the final cost of the calculation, since in most cases there is a multiplication by various indices and prices, therefore the magnitude of the error is increasing all the time;

Mistake 3. Incorrect application of the prices contained in HESNs and TEPs. One of the main problems of the basic-index method, which is 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, it is often necessary to use the available rates "applicable". This is a special term coined by surveyors for a similar situation. The more “applicable” quotations are used when filling out the estimate, the more likely it is that the final figure will be incorrect. Naturally, it is worth considering the fact that customers try to use low "applicable" prices, while contractors, on the contrary, are the most profitable.

In any case, the preparation and execution of the estimate 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 allow not only to formulate the cost of work that is optimal for the customer and contractor, but also to organize their effective implementation in the shortest possible time and at the lowest possible cost.

Just as a theater begins with a coat rack, any renovation begins with a budget. It does not matter whether we are talking about the renovation of an entire house, a separate room or a bathroom, the estimate is simply vital. Especially when it comes to hiring professional builders.

In this article, we will look at how to correctly make an estimate for the renovation of an apartment, as well as what features you need to take into account when drawing it up.

What is an estimate?

The estimate is a list of all the necessary work, necessary to achieve the goal. In this case, apartment renovation. This document specifies the parameters of the necessary work, the cost of work, as well as the amount and cost of materials and related services for their delivery.

An estimate is needed regardless of whether you will do the repair yourself or hire professional builders. It allows you to determine the budget for future repairs and measure it against your capabilities. Without it, there is a high probability that once the repair is started, it may never be completed. And all because the money ran out or mandatory work was overlooked.

Who makes the estimate?

Making an estimate for the renovation of an apartment or a private house is best entrust to a professional. Thanks to their rich experience, specialists know all the subtleties of the process, as well as which pitfalls need to be avoided. In addition, they almost by heart remember all the coefficients to the prices from the technical part, the entire regulatory framework.

As a rule, most of the repair crews make up their own estimates before repairs. This allows the customer to save time and headaches. However, if you wish, you can make an estimate yourself.

The services of a professional expert in construction quality control will help reduce the overall cost estimate.

You can learn more about how to make an estimate yourself.

Estimating rules

Self-budgeting is a rather painstaking process, but there is nothing complicated about it. Naturally, the document must contain the volume, the price of the craftsmen, the necessary building materials. However, not all so simple. Budgeting involves the introduction of three main categories of costs. These categories include direct and overhead costs, as well as estimated profits.

Direct costs are the main cost item of the estimate. This category includes the cost of building materials, workers' wages, as well as costs associated with the operation of construction machinery and machines. The last point is especially relevant when it comes to drawing up an estimate for the repair and finishing work of a real estate object. Based on the cost of direct costs, the amount of overhead is assumed. Usually we are talking about an amount in the range of 12-23%, but with significant deviations for certain types of work.

Category overhead costs include funds spent on providing working conditions and for organizing the repair process. Such costs include the cost of delivering and unloading materials, the work of loaders, the cost of garbage collection and cleaning the apartment. This also includes the cost of maintaining the equipment and the fees for the supplier and foreman.

Estimated profit represents funds intended to cover the costs of contractors for the development of production and material incentives for employees. Estimated profit is a normative part of the cost of construction products and does not relate to the cost of work. Together with direct costs, overhead costs become the basis for calculating the estimated profit, which is usually 8-12% of this amount, but can be much more.

When making an estimate, you should take into account the correct order of its preparation... All estimates for the estimate are carried out in a strictly defined order and are made for each stage of the repair work separately:

1. At the first stage, the cost of dismantling should be calculated.
2. Next, the cost of general construction works is calculated. At the same time, the estimate for the work on carrying out communications is calculated separately.
3. Last but not least, an estimate is made for finishing work on ceilings, walls and floors.

As a rule, the calculation of repair construction work is carried out for individual rooms: bathroom, toilet, living room, kitchen, and so on.

When calculating the need for building and finishing materials, it is necessary to calculate all areas and measure the perimeters of the surfaces to be repaired and take into account the consumption rates that each material may have, they are usually indicated on the packaging. The estimator should also take into account that work on uneven surfaces or with wallpaper, the pattern of which requires docking, increases the consumption of materials, which should also be reflected in the estimate.

Estimate calculation

Now that we have figured out the main categories of costs, we can proceed to drawing up the estimate itself. In its simplest form, you can take a simple sheet of paper and draw up a table on it. Besides, you can also make estimates on a computer, moreover, specialized programs can be used to calculate them. Among these programs are: "Grand Estimate", "Turbosmetchika" and "SmetaWizard".

In this case, we will focus on the simplest version with a sheet of paper or a table in a text editor. First of all, you should break the sheet into columns by categories:

• Type of work;
• Quantity;
• Unit price;
• The total amount.

Direct costs are grouped in the tabular section according to the names of structural elements for the repair of which they are directed. Overhead costs and planned savings are included in the estimate in separate sections.

Next, we indicate the entire list of upcoming operations. In this case, the square of the room, the perimeter of the room or the area of ​​a single wall or ceiling should be calculated. We multiply the resulting figure by the prices and get the total for each line. We add up the totals and get the amount that you will pay to the masters.

To calculate the total cost of materials, we indicate the required materials and their cost against each line. Fill out the cost of the necessary building materials in a separate list indicating the quantity and prices.

It is better to write in the table not just the general name - for example, “putty” or “wallpaper”, but also indicate the brand, name and color of the product. This will allow you to more accurately navigate the purchase and indicate a more specific price.

We add up the cost of work and materials. As a result, we get the approximate cost of the repair. To the amount received, we add unforeseen costs for consumables, tools, delivery vehicles and other related costs.

Having made this simple calculation, you will be guided in advance in the upcoming expenses. And if the funds are not enough, then you can save on the cost of materials - buy cheaper wallpaper, flooring, baseboards, etc. Or try to negotiate a price cut with the craftsmen.
