Common Questions

Frequently Asked Questions

Answers to the questions we hear most often about our BIM Services.

A comprehensive Electrical System Design package includes Single Line Diagrams (SLD), Three-Line Schematics, connected load schedules, transformer and switchgear specifications, short-circuit and voltage drop calculation, cable conduit routing, and earthing grid layouts.
Our engineering deliverable strictly adhere to global standards, including the National Electrical Code (NEC / NFPA 70), IEEE standards, NFPA 70E, and IEC guidelines.
We typically require the connected load list, site utility supply voltage details, environmental operating conditions, preferred equipment specifications, local utility grid requirements and reference or sample files.
Cable sizing is calculated based on continuous load current, ambient temperature de-rating factors, cable grouping/installation methods, maximum allowable voltage drop limits (per NEC/IEC standards), and short-circuit withstand thermal ratings.
Yes. We evaluate existing electrical utility infrastructure, recreate missing single-line schematics from field site data, re-evaluate expanded load requirements, and design modernized substation feeder upgrades and earthing grid expansions.
