Occupation features of budgeting for a feast. Drawing up estimates for design and survey work. of the total cost of construction

Before proceeding to the installation of electricity in the house, you need, as well as an estimate for materials. This is necessary in order to calculate the approximate (or even exact) costs and during electrical installation not to encounter a situation where there is not enough money for sockets or switches. Based on the prepared cost table, you can understand whether there are enough material resources or it is better to purchase cheaper materials in order to surely get away from shortage problems. Next, we will tell you how to make an estimate for electric installation work by providing step by step instructions with video as well as a sample.

Step 1 - Prepare documents

The first step is to prepare the documentation on the basis of which the estimate for electrical installation will be drawn up. For calculations, you need to collect the following documents:

1. Plan of the room, which will indicate the wiring diagram.
2. Electrical equipment placement project.
3. Specifications to be taken from the electricity supplier (if necessary). About that, we told in a separate article.
4. Permission to connect to the power grid (if necessary).

In addition, depending on the situation and the characteristics of the facility, you may need an act of balance ownership, a document on the limitation of operational responsibility, as well as an order for the supply of electrical equipment. All these documents are mostly used in enterprises. As a rule, in order to make an estimate for electrical work in a residential building, it is enough to prepare the first 2 documents from the list, as well as a permit for electrical installation.

Step 2 - Performing the calculation

Calculating the cost of installing electrical wiring is not too difficult, but you will have to take this procedure seriously enough. The more points indicated in the estimate, the less likely that at the end of the electrical installation there will be situations due to which you will have to overpay. So, drawing up an estimate for electrical work consists of the following steps:

1. Obtaining a floor plan with reference to electrical appliances. You can get it from BTI.
2. Issuance of a permit to connect to the power grid.
3. Bringing everyone specifications to the standards.
4. Quantity calculation based on wiring diagram.
5. Search for the best deals on materials.
6. Cost calculation.

If, after you make an estimate for, it turns out that there is not enough money, you will have to reconsider the project and, if possible, either remove some electrical points or purchase cheaper materials.

This manual is suitable for those who want to independently calculate the cost of installing electricians. If you doubt that you can correctly draw up an estimate of electrical work, it is better to entrust this matter to specialists, but they, of course, will take money for this. Another important point Who will do the electrical installation. Would you like to conduct electrical wiring in your own home? Then you skip this moment. If it is assumed that the electrician will be carried out by a company or a private electrician, it is necessary to find out what the cost of electrical installation will be, as well as the dismantling of the old network (if the apartment is not a new building) and be sure to include this figure in the estimate.

Please note that many companies offering electricity services have their own online calculators on their websites, with which you can quickly calculate the cost of electrical installation. In the same place, as a rule, you can find prices for the installation of certain electrical points (sockets, switches, meters), cable laying and wall chasing for wiring. This information will allow you to easily calculate the cost of electrical work at the new prices.

It should also be noted that estimates are complex (for the entire facility) or local (for a separate room / room).

It is best to create a cost plan in Microsoft Excel. All you need is to download this program to your computer, install and create a table in it. Next, enter all the values ​​\u200b\u200bin the table, after which, based on the formulas, make calculations. How the estimate for electrical work in Excel is prepared is clearly described in the video example:

Sample of settlement works

Prices for 2019

Well, the last thing I would like to provide is the approximate prices for the installation of electricians in residential premises. So, in 2019, the cost of electrical installation is as follows:

• installation of a cable channel (1 r.m.) - 120-180 rubles. (depending on the material of the walls and the dimensions of the product);
• cabling open way about 60 r. per linear meter, 60 with hidden wiring;
• installation of a circuit breaker - 300-600 rubles;
• installation of a shield - from 1500 to 5000 rubles;
• connection of a wall sconce - 700 rubles;
• socket installation - 300 r.

These are the main prices for electrics, which we recommend focusing on when drawing up an estimate for electrical wiring work. In general, excluding the price of materials, the cost of electrical installation in 2018-2019 will be (in rubles):

• one-room apartment: from 18 thousand if the walls are made of brick, from 25 thousand if they are concrete;
• two-room apartment: from 25 thousand (brick), 35 (concrete);
• three-room apartment: 40 thousand (brick), 45 (concrete);
• wooden cottage: up to 100 sq.m. 65 thousand, over - from 95 thousand;
• brick house: up to 100 sq.m. 75 thousand, over - from 110.

That's all I wanted to tell you about how to make an estimate for electrical work in an apartment and house. We hope that our instructions were useful and understandable for you.
