Frequently Asked Questions:

Why is an electrical load calculation required before construction or applying for a power meter?

Accurate load calculation ensures requesting the exact breaker capacity from SEC without paying unnecessary excess fees, avoids rejected power release applications, and eliminates costly oversizing or hazardous undersizing of main cables.

Do you provide electrical calculation services for industrial facilities and warehouses in Jeddah?

Yes, we perform advanced load studies for industrial plants, logistics warehouses, motor drives, central HVAC systems, and design main/sub-distribution panels (MDB/SMDB).

Does the BOQ include material pricing and installation costs?

Yes, our engineering BOQ includes comprehensive quantity surveying with optional cost estimation reflecting current Saudi market prices for certified materials and on-site labor.
