Which type of drawing indicates where electrical services are installed in a building?

Electrical drawings specifically illustrate the design and layout of electrical systems within a building. They provide detailed information regarding the placement of electrical services, such as outlets, switches, lighting fixtures, panels, and wiring. These drawings ensure that all electrical installations comply with relevant codes and standards while providing a clear guide for installation and maintenance.

In contrast, civil drawings primarily focus on the physical layout, grading, and site development aspects of a project, while mechanical drawings pertain to the HVAC (heating, ventilation, and air conditioning) systems and plumbing. Fire protection (FP) drawings center on the layout of fire suppression systems and related safety equipment. Each of these types of drawings serves distinct purposes, but for electrical service information, electrical drawings are the definitive source.
