2. Electrical Design and Supervision of Electrical Construction

2.1. Electrical design

Important considerations in the electrical design of buildings are as follows.

Building usage and number of people: The appropriate power capacity should be calculated by considering the use of the building and the number of people, and the appropriate lighting equipment and outlet location should be determined.

Electrical Safety Regulations: Domestic and international electrical safety regulations regarding the installation of electrical equipment must be observed.

Electrical Safety: Protective devices such as ground, circuit breaker, and short circuit breaker must be installed to ensure the safety of electrical equipment inside the building.

Environmental requirements: The location selection and wiring composition of the electrical installations inside the building should take into account environmental requirements (humidity, temperature, dust, etc.).

Reliability: To increase the reliability of the electrical installation, a backup installation should be installed in critical areas, which requires separate space and power supply to be considered.

Energy Saving: As electricity bills rise and the need to conserve energy increases, there is a need to reduce electricity usage by introducing energy-saving electrical equipment and energy management systems.

Convenience: The convenience of electrical equipment inside a building is an important factor in enhancing the convenience of building users. The location and type of lighting, switches, and outlets should be installed in consideration of the user's convenience.

Lighting Design: Lighting design is a factor to be considered to ensure proper lighting inside the building, such as the type of lighting, the location of the lighting, and the intensity of the light.

Communication System : The electrical equipment inside the building should also include the communication system. It should be designed with the communication system installation location and configuration of the Internet, telephone, CCTV, etc. in mind.

Maintenance : The electrical installation inside the building requires long-term maintenance. Therefore, the configuration and installation location of the facility should be configured and deployed to facilitate and efficient repair and maintenance.

2.2. Electrical Construction Supervision

- Electrical construction supervision refers to the technical review and supervision of the construction and maintenance of electrical facilities conducted at the electrical construction site.

- The procedure of supervision is based on the guidelines for performing the construction supervision of power facilities.

- It will be implemented during the supervision period specified in the contract for electrical work.

- It manages the entire process of facility construction, maintenance, safety inspection, and commissioning.

- Evaluate and review the quality, safety, reliability, and economic feasibility of electrical equipment.

- The supervisory authority must have technical knowledge and expertise in the supervisory process.
