Commercial Building Electrical Documentation

Project overview

Complete electrical documentation set for a 12-storey commercial office building covering main switchboard, distribution boards, sub-mains, final sub-circuits, lighting, power, emergency systems and tenancy fitout allowances.

The challenge

Coordinating panel schedules and cable routes across 12 floors with multiple tenancies and a complex services riser. The original concept lacked cable sizing calculations and didn't address fault-level requirements at distribution boards.

Our approach

Produced single-line diagrams, panel schedules, cable schedules with full sizing calculations per AS/NZS 3008, lighting and power layouts per floor, and emergency/exit lighting plans. All drawings cross-referenced against the architectural and structural drawings to avoid services clashes.

Outcome

Documentation passed certifier review on first submission. Construction phase ran without RFI delays on electrical scope.
