Why Engineering Quality Matters

A well-engineered electrical system reduces installation errors, prevents costly rework, and ensures long-term operational safety. Our design deliverables are produced to be construction-ready — clear, accurate, and fully coordinated with all project disciplines.

End-to-End Electrical System Design for Industrial and Construction Projects

At Niroo Azarakhsh Fartak, electrical design is the foundation of every project we deliver. Our engineering team develops complete, construction-ready electrical design packages for industrial facilities, commercial buildings, and infrastructure projects — all produced in strict compliance with IEC, IEEE, and applicable national standards.

From the earliest stages of a project, our engineers work closely with clients, architects, and mechanical teams to develop electrical systems that are technically sound, cost-efficient, and aligned with long-term operational requirements. Every design is reviewed and validated internally before issue, ensuring accuracy and consistency across all documents.

What Our Electrical Design Service Includes

• Load Analysis & Power Demand Studies — Accurate calculation of connected loads, demand factors, and future expansion allowances to correctly size all system components.
• Single-Line Diagrams (SLD) — Clear and detailed SLDs showing the complete power distribution architecture from the supply point to final sub-circuits.
• Short-Circuit & Protection Coordination Studies — Fault level calculations and protection relay coordination to ensure safe and selective system operation under fault conditions.
• Cable Sizing & Routing Design — Systematic cable selection based on current carrying capacity, voltage drop, and installation method — with detailed cable schedules and routing layouts.
• Earthing & Lightning Protection Design — Design of earthing systems and lightning protection in accordance with IEC 60364 and IEC 62305 standards.
• Panel & Switchboard Schematics — Detailed schematic diagrams for LV distribution panels, motor control centers (MCC), and control panels.
• Lighting Design & Calculations — Photometric analysis and lighting layout design for industrial, commercial, and outdoor environments, verified against applicable lux level standards.
• Technical Specifications & Bill of Materials — Comprehensive technical specifications for procurement, together with detailed material take-off and bill of materials.

Our Design Standards & Approach

All design work is carried out in compliance with internationally recognised engineering standards, including IEC 60364 (Low Voltage Electrical Installations), IEC 60909 (Short-Circuit Calculations), IEC 61439 (Switchgear & Controlgear Assemblies), and relevant IEEE standards. Where applicable, local regulatory requirements and utility connection standards are fully integrated into the design.

Our engineers use industry-standard software tools for load flow analysis, short-circuit calculations, protection coordination, and cable sizing — ensuring that every design decision is backed by rigorous technical analysis rather than estimation. All design documents are version-controlled and issued with formal drawing registers, enabling clear change management throughout the project lifecycle.

Design Deliverables

At project completion, clients receive a full design package including: single-line diagrams, schematic drawings, cable schedules, equipment schedules, earthing layout drawings, lighting layout drawings, technical specifications, protection coordination reports, and a complete bill of materials. All documents are issued in both PDF and editable native formats upon request.
