Everyone who wants to build a house or make repairs in an apartment initially calculates how much it will cost him. For complete clarity, it is necessary to draw up a list of necessary materials and work, as well as their cost. Based on this, it will be possible to find out how much money is needed. And also decide whether to involve builders or do everything yourself. Not everyone knows how to make an estimate, what positions to include in it and how to calculate everything correctly. Let's try to figure this out.
What is an estimate
An estimate is a document that systematizes all costs for the upcoming construction or repair. This can easily be done on your own, without having specially designed programs.
How to make an estimate on your own? It is enough to have the Excel program on your computer. It is necessary to carry out the calculation of funds and materials very carefully in order to avoid errors and exceeding the planned costs. It should display everything to the smallest detail.
Common Mistakes
When drawing up estimates, many make mistakes, which then come out and provoke unforeseen expenses:
- Calculations are made without a preliminary inspection of the facility where the work will be performed.
- Additional expenses that may arise in case of force majeure are not included.
- The full list of works and materials is not taken into account.
The main expense document for repairs or construction requires a serious approach and accurate calculations. Otherwise, you may get incorrect results.
What is needed for a competent budgeting
Before drawing up an estimated estimate for construction or repair, first of all, you need to inspect the object. After that, a list of all ongoing work should be compiled.
How to make an estimate? You need to know construction technology. Without this, it is impossible to correctly and correctly calculate and record all upcoming expenses. Therefore, we recommend that before making an estimate, study the sequence of the production cycle of work that needs to be evaluated. This will help to understand the need for ongoing operations and the need for building materials.
Main budget items
Any construction estimate consists of three main items:
- materials;
- work;
- transport.
All other items (cost of electricity, equipment operation, etc.) are added to them.
In the first position indicate the list of necessary materials for each cycle of work, unit of measurement, quantity and price. For example: brick, glue, plaster, cement, wallpaper, linoleum and others. This also includes "consumables" (brushes, rollers, gloves, etc.). Before making an estimate, find out the cost of materials directly in the store, or search the Internet on sites specializing in the sale of building materials.
The second position includes a listing of all actions performed. Here it is necessary to take into account both preparatory and finishing work, their complexity and the conditions in which they are carried out. For example, you need to paste over the room with new wallpaper. To do this, you will need to carry out preparatory work: remove the old coating, clean the walls, prime them. The approximate cost of the necessary work can be found in the ads.
The position "transport" includes: delivery of materials, unloading, removal and removal of construction debris, indicating each item on a separate line. Information about the cost of these services is provided in the price lists of firms.
Estimate for apartment renovation
How to draw up an estimate in order to carefully plan the repair work in the apartment, finish them in a short time with minimal costs? First you need to decide what kind of repair you will do: cosmetic or major. It depends on the amount of materials needed and the amount of work. If you decide to carry out a major overhaul, then the estimate should be divided into two parts:
- repair and finishing works;
- roughing and finishing materials.
How to learn how to make an estimate to avoid mistakes? To do this, you should inspect all the premises of the apartment, measure the surface area of walls, floors, window slopes, make a list of finishing and draft materials, determine the cost and scope of work for each room separately.
Example
Let's give an example of how to make an estimate for repairs. Prices and consumption of materials are fictitious.

To get the preliminary results of the cost of apartment renovation, you need to add the totals from each column.
18819 + 7870 + 4000=30689 (RUB)
You should be aware that the final costs always come out more by 10-15%.
30689 + 15%=35292.35 (RUB)
The principle of calculating the cost of construction does not differ from the estimate for repairs. Only production cycles and materials will change. How to make an estimate for construction with minimal costs? To do this, you need to carefully plan all the work, clarify what materials will be needed, find out the prices.
Estimating is a very important step from which to start any repair or construction. A properly drawn up document will help to carefully plan and rationally allocate costs - both material and money. The main thing is to take the calculations seriously and perform them as accurately as possible.
