I have played an integral role in several significant electrical substation projects in Saudi Arabia,
demonstrating expertise in both design and implementation. Notably, I led the design efforts for
the GIT Makkah Substation, operating at 110kV/13.8kV, as well as three additional substations in
Al-Nariyah, Taif, and Qatar, each with a voltage range of 33kV/13.8kV. Additionally, I contributed
to the NEOM project, specifically in the tender bid design for labor quarters, showcasing my
versatility in optimizing living spaces within large-scale developments.
My responsibilities included managing design-related project activities for 110/13.8kV substations,
including the GIT Makkah Substation, as well as substations in Al-Nariyah, Taif, and Qatar. I also
provided fire alarm designs for eight substation projects. I was responsible for ensuring project
implementation followed the contract agreements by closely coordinating with clients.
