Optimal use of water, electricity, gas, ventilation, warning signs, sewage disposal, heating and cooling system, communication between inside and outside the building, telephone calls, transportation between floors are installation issues. Each of them is calculated with the help of engineers and technicians and produces safety, beauty, and strength with accurate implementation. The use of aluminum pipes with non-fouling transmission pipes, as well as the use of polymer pipes for sewage, development layers for passing power wires with standard coating, is on the agenda.
Access to ducts, posts, and checkpoints is mandatory. Insulation is a fundamental and widespread category in the building and plays a key role. All heat exchanges, light, odor, sound, dust, moisture, prevent the combination of metals with oxygen in the air, barriers to insect penetration, are part of the insulation. In each section, it uses the necessary materials and creates insulation. Care in the implementation of the facility and knowing its importance and observing the exact points as mentioned will lead to the durability of the building. The beating heart and vital artery is the building of the facility, which is responsible for the movement of energy in various forms.

The beating heart and vital artery is the building of the facility, which is responsible for the movement of energy in various forms.
The order of electrical work of the building is as follows:

first stage :
1. Drawing a building plan including lighting systems, sound systems, electrical sockets, telephone, antenna, iPhone, fan coils, fire extinguishing, emergency power, and engine room.
2. Execute the map on the job.
3. Align the entire can box and draw the alignment line with the check line.
4- Grooving the path of the pipes with a stencil and a grooving device.
5. Dig the key box with the device.
6- Perforation of the ceiling light by the device (in the case of a false ceiling, it is fastened on the roof and the pipe is fixed on it).
7. Install the key box on the wall with a template and align them accurately.
8- Welding and support to fix the polyconic pipes that are brought for the inlet and outlet of the pipes that are brought inside the fuse box.
9- Welding and support to fix the policy tube that is brought to the input and output of the tubes that are brought inside the antenna and telephone box.
10- Execution of police pipe by heat and bending by torch and spring and sealing it by polka glue.
11- Welding and construction of support for power tray on the duct marked on the map (these trays are electrical for entering power cables, telephones, satellite antennas, etc.). Becomes your need).
12- Complete cover on the pipes of the polishes that have been worked on the floor of the building.
13-Installing the fuse box and aligning it in places specified by the map.
14- Installing the antenna, satellite, and telephone boxes and aligning them in the specified places by the map.
15- Providing earthing of the building (installation of copper plates, wires, coil and salt to start the earthing well and from there to the electric tray and the consumers)
16- Laying steel pipes in the conditions specified by the plan (in the parking lots of offices inside the elevator lighting and engine room lighting).

The second stage (after flooring, tiling, and wall whitening):
1- Cleaning the key box and cutting the extra pipes on the work.
2- Wiring inside the Polika pipe (the color of the wires and the diameter of the wires and the material of the wires are selected according to the standard).
3- Drop the shielded cable for the speakers and from there to the volumes of the same room and from there to the plugs behind the amplifiers.
4- Electrical cabling from inside the fuse box and passing inside the electrical tray and fastening and from there to under the meter (if you have a diesel generator, these cables will enter the motor of the house and enter its own panels).
5. Telephone cabling - Satellite and iPhone antennas from their own panels and pass inside their own tray and fasten the cables and from there to their own boxes.
6- Connections of wire heads inside the key box, fuse box, lights, built-in and antenna box, satellite, telephone, fire extinguisher, installation of UPS power devices.
7- Tin lining all connections and wires by the tin pool.
8- Insulation of joints by thermal varnish (replacing electrical pads).
9- Execution of cabling related to the outside of the building, installation of floodlights in the facade.

The third step (after painting and finishing the floor):
1. Close the switches and sockets and align them.
2. Close the terminal on the wires.
3- Install smoke detectors and their knobs on designated places.
4- Installing fuses inside the fuse box and wiring the wires and fusing them.
5- Installing the video iPhone, closing the sockets, and related knobs.
6- Installation of the central antenna and related switches.
7- Installation of satellite switches.
8- Installing light eye on stairs and parking lots.
9- Installing the light eye in the services for the central hood (these eyes, after operating on the contactor and then the contractor, command the centrifuge and cause the services to be ventilated).
10- Installing hidden lights inside the false ceiling and insoles on ceramics.

Installation of electrical engine room equipment:
1- Installing the electrical panel of the engine room (the equipment inside the electrical panel is selected based on the needs of the engine room and is made by the panel maker)
2- Installing the power tray base on the wall and fixing the power tray on it.
3- Installing electric underground pipe and from there on electric motors, thermostats, and other consumers.
4- Cabling from the electrical panel on the electrical tray and inside the pipe, from there to the heads of electric motors, thermostats, and consumers.
5- Wiring and numbering the wires and closing it on the terminal boards of electric motors, thermostats, and consumers and from there to the terminal under the electrical panel.
