Estimates for electrical work. Examples of drawing up estimates for electrical work

When creating any project, the estimate is an important document, the purpose of which is to determine all the required costs, taking into account the labor resources and materials used. Electrical work plays a very important role in the construction, so in this case, saving money at the expense of quality is unacceptable. In this connection, serious attention is required to drawing up estimates for electrical work.

Required Documentation

For the calculation of estimated costs, a plan for the location of the BTI, tied to electrical equipment, and a design project for the electrical section are needed. The following documents will also be required:

• Resolution for power connection;
• TU for electrical work;
• Document on limitation of operational liability;
• Act on balance sheet;
• Design of electrical equipment.

An explanatory note, a single-line power supply scheme (calculated), a plan of group networks (lighting and electrical equipment), a scheme for additional equalization of potentials and coordination of the plan in Rostekhnadzor should also be included.

Among other things, there is an order for equipment for wiring, which includes information on the length of all wires, their manufacturer and auxiliary materials. The outfit is made with the same accuracy as the estimate.

Variety of estimates

Estimates for electrical work are divided into two categories: consolidated (complex), compiled for the entire building, and local (object), performed separately for the premises. Before you start writing them, you need to justify the investment. In this case, the estimated cost of all work is determined. Documents can be presented in two forms:

• Estimated calculation (contains a detailed cost price with an overestimate of the level of costs);
• Estimate (calculation is carried out according to the project drawings).

The second type allows you to make estimates for electrical work more qualitatively.

List of works

First of all, the costs of working should be described. This will in the future avoid the price increase. The list of works is presented below.

1. Installation of the wiring (open) on the brackets on the concrete surface and on the plaster walls.
2. Paving of the corrugation (open).
3. Placement of an electric box on concrete, a brick platform and a plasterboard.
4. Installation of the consignment of the pick-up box.
5. Installation of the switch, socket and decorative insert.
6. Installation of the hinged box in the plaster, brick wall and concrete.
7. Change of triple electric block.
8. Installation of the juniper.
9. Setting the button for an electric bell.
10. Build an electric bell.
11. Creation of a hole in a gypsum plaster (brick, concrete wall) for the subgrid.

Algorithm for writing: Stage 1

When drawing up an estimate for electrical work, it is necessary to determine the exact amount that is intended for the event in question. Further, the principle of operation is described below.

1. Get a plan of the room with a binding to electrical appliances. This can help the BTI or the studio, which compiles projects on the electrical part.
2. Obtain permission to connect capacity. This should be done in the EEA or the HOA. In the same organizations, it is necessary to take a document on the division of operational responsibility between the balance holder and the owner.
3. To bring to specifications all technical conditions, as they are strictly checked, and any deviation entails a refusal.

Algorithm for writing: Stage 2

After performing the previous operations, you need to make a number of important actions.

1. To address to the good experts making a project of electrodevices. At this stage, it is important to turn to experts, because only professionally performed work can guarantee a safe and permanent operation for a long time.
2. Choose the best firm that provides installation services. To do this, you should inquire about information about it, learn about customer feedback on quality. Estimates for electrical installation work necessarily include these costs.
3. Find suitable electrical appliances and include their cost in the estimate.
4. Calculate the ratio of costs and balances. If the funds are not enough, you should make the project easier by choosing less expensive equipment.

An example of an estimate for electrical work

In the title of the document in question, the type of estimate, object, is written. The front page shows the total cost, installation costs, the calculated labor input and the estimated salary. More detailed information is presented in the form of a table divided into several graphs. A sample of the estimate for electrical work is presented below.

The first column is the serial number, the second is the position. In the third, the cipher and the work itself are indicated. In the fourth column, the quantity must be noted. Then follows the graphs with the cost of work and labor costs. At the end of the table, the results are summed up, as well as the person who made the estimate, and the one who checked (the position, the signature, the full name).

Drawing up estimates for electrical work is a rather troublesome and time-consuming process. Calculate its value at present allow different methods of calculation: mixed, index, compensatory, resource. It will greatly simplify the task and avoid the mistakes application of specialized software, because the cost depends on the cost of electrical work, and this affects the quality and the length of the equipment's service life. To do everything at a high level, you can contact the company's electricity supply design department. Experts will do all the work qualitatively in the shortest possible time.
