Introduction of electrical facilities design
The design of electrical installations includes the design of lighting systems, elevators and escalators, lightning arrester systems, warning systems, design of signs and risers, etc. For this purpose, the final architectural plans are received by the client or the architect and the items mentioned on the plan are implemented in the most optimal way possible.
Electrical installation design steps
Consultation with the employer
In the design department of electrical installations, like mechanical installations, the first issue that comes up is consultation. Many elements change depending on the type of request of the employer and the level of the project. For example, if smart building design is considered, this factor can have a great impact on the cost and design of electrical installations.
As a result, consultation with the architect and the employer is very important.
Detailed drawing of electrical installations
Regarding the drawing, the design is started according to the scale of the project and the client’s requests. The number of floors affects the amount of power consumption and therefore the type of design. For example, if ventilation systems with high consumption power are used in the design, the type of cable and also the scale of the electrical panel will change. Electrical plans are drawn separately by AutoCAD and Revit software, which means that the lighting system is separate from the fire alarm system, as well as the rest of the systems. At the end, the details of the electrical panels are drawn, as well as the table of items used. And the estimated meter is created as an Excel file or inside the map itself.
Implementation and supervision of electrical installations
At this stage, an experienced team, including a supervising engineer and an electrical technician, performs the implementation and supervision at the same time. The duty of the electrical technician is to implement all the equipment and power supply lines, and after the completion of each step, it is checked by the supervising engineer. If there is any problem or change in the execution of the project asbuilt plan, which is the correction plan, it will be presented to the employer.
Important points in the design and implementation of electrical installations
- In order to improve the performance of electrical equipment, it is necessary to use a special brand to prepare the equipment.
- Using multiple brands in one project may lead to errors.
- It is necessary to coordinate with the building and mechanical installation engineer because the whole process must be done in a certain time without interfering with the mechanical installation.
- In terms of coordination with the building, it should also be considered what the process of finishing the building work is for each unit, so that re-destruction is minimized.
- The size and meter of the required cables must be calculated very precisely according to the power consumption.
- To calculate the amount of consumption and also the size of the cross section of the cables, they raise to reduce the risk of problems.
- The type of material used during execution is very important.
- The use of fireproof cables and equipment with appropriate IP conditions has an important impact on the longevity and quality of the project.
- In the main electrical panel, it is necessary to use a capacitor bank if needed.
- Order in the production of electrical panels and name tags , helps the technician for maintenance and repair.
- Maintenance of electrical drawings is an important issue that is often ignored, but if they are maintained after the completion of the project, the electrical technician of the building will have a correct view of the division and implementation method to solve the existing problem more easily.
- The final test at each stage of the work has a great impact on the secondary costs. This is because the final test prevents the occurrence of a short circuit in the circuit of the building.
Conclusion:
Even though Mehraz Shahr Iranian company has all its technician in the design of electrical and mechanical installations, architecture and execution, we can complete your project from zero to one hundred. The advantage of this method is that all the responsibilities are with the company itself, and it also creates a significant reduction in costs, and finally the errors in the completion of the project are minimized.
