Commercial electrical systems must deliver reliable power to diverse loads — from LED battens and data switches to commercial refrigeration, HVAC plant, and point-of-sale infrastructure — without ever becoming the reason a business closes early. VoltCity Surge brings project-management discipline, AS/NZS 3000 compliance rigour, and the crew depth to handle multi-trade fit-outs without bottlenecking construction programmes.
Office and Retail Fit-Outs
A successful tenancy fit-out depends on co-ordinated sequencing across hydraulics, joinery, data cabling, and electrical. We work directly from your architect's or interior designer's plans, issue shop drawings for approval, and schedule rough-in, fit-off, and commissioning stages to avoid conflicts with other trades. Our teams are accredited to work in live retail and hospitality environments, including after-hours and weekend shifts that keep your trading floor undisturbed.
Three-Phase Power Distribution
Many commercial tenancies arrive with single-phase supplies that are wholly inadequate for commercial kitchen equipment, lifts, air-handling units, or production machinery. VoltCity Surge manages the complete upgrade pathway: load calculations per AS/NZS 3000 Section 2, application to the local distribution network service provider (DNSP) for augmented supply, sub-board design, and cable routes sized to AS/NZS 3008 current-carrying capacity tables for the actual installation method and ambient temperature.
- Switchboard and sub-board design, supply, and installation
- Three-phase power for commercial kitchens, lifts, and HVAC plant
- LED lighting systems with DALI or 0–10V dimming control
- Power circuit distribution for workstations, server racks, and POS terminals
- Uninterruptible power supply (UPS) integration for critical IT loads
- Exit and emergency lighting to AS 2293 compliance
- Electrical compliance certification for council DA and occupation certificate
Lighting and Power Distribution Design
Energy efficiency targets under the National Construction Code (NCC) Section J now impose maximum lighting power density limits for commercial buildings. Our design team works with lighting designers to select luminaires, drivers, and control systems that achieve NCC compliance while creating the illuminance levels your fitout requires. We model lux distributions, specify dimming zones, and programme occupancy and daylight sensors to reduce your ongoing energy spend.
Compliance, Certification, and Documentation
Commercial electrical projects generate a compliance paper trail that flows from the building permit through to the occupation certificate. VoltCity Surge prepares and lodges all required Certificates of Compliance for Electrical Work (CCEW), maintains as-built drawings in an AutoCAD-compatible format, and provides switchboard schedules in a format accepted by your certifier. We also liaise directly with your energy retailer and DNSP for metering installations and supply agreements.
After-Hours and Live-Environment Work
Cutting power to a busy office or a trading retail tenancy mid-day is rarely acceptable. Our after-hours and weekend crews are trained in energised-adjacent work procedures and carry the appropriate tools and PPE to execute planned outages within pre-agreed windows. We co-ordinate with building management on emergency evacuation procedures, temporary lighting provisions, and EWIS (emergency warning and intercom system) isolation to maintain life-safety compliance throughout the work.
Testing, Commissioning, and Handover
Commercial electrical installations are commissioned using a structured test programme based on AS/NZS 3017 verification procedures. We conduct insulation resistance tests on all new cable runs, continuity verification of protective conductors, functional testing of RCDs, earth electrode resistance measurements where required, and lighting-control system commissioning that includes programming occupancy sensors and daylight harvesting thresholds. All results are recorded and provided to the builder or project manager alongside as-built drawings and the switchboard schedule at practical completion. Where AS 2293 emergency lighting is installed, we issue the required commissioning record and arrange the 90-minute duration test in the presence of your building certifier if required.
Frequently Asked
Do you handle the DNSP application for a three-phase supply upgrade?
Yes. We prepare the load schedule, complete the network operator's connection application, and manage all technical correspondence on your behalf. Timeframes vary by distributor and location — typically four to twelve weeks for augmented supplies — and we factor this into the project programme from day one.
Can you work after hours to avoid disrupting our business?
Absolutely. After-hours and weekend scheduling is standard practice for our commercial division. We quote any site-allowance or shift-penalty costs transparently in the tender so there are no invoice surprises, and we brief our crews on building access protocols and security requirements before mobilising.
What documentation do you provide at practical completion?
We provide a full compliance pack including all CCEWs, as-built drawings, switchboard schedules, test records per AS/NZS 3017, emergency lighting test certificates per AS 2293.2, and operation-and-maintenance manuals for all installed equipment. These are delivered in both hard copy and digital format to your nominated project manager.
