ELECTRICAL DESIGNING & DRAFTING
Electrical system design is a sub discipline of MEP of which needs keen attention in design, drafting and installation. Electrical system is the master key in proper functioning of MEP facilities and the building. And as it is highly prone to accident like fire,shock,explosion,Electrical systems of the building should be designed by following local codes and international guidelines to ensure high safety, reliability and long life.
