High Risk Construction Work Types
- •Work on or near energised electrical installations
Risk Assessment
1.Site survey and load capacity assessment
| Hazard / Risk | Initial Risk | Control Measures | Residual Risk | Responsibility |
|---|---|---|---|---|
| Overloading existing electrical infrastructure | High | Conduct a full electrical load assessment of the existing switchboard and incoming supply before specifying charger type and quantity. Obtain a load data logger reading over a minimum 7-day period to determine peak demand. Confirm available spare capacity with the network operator (DNSP) and obtain a formal supply capacity statement. Where total new EV load exceeds available capacity, engage the DNSP for a supply augmentation application before commencing installation. Document all load assessment findings in the project technical report and have it reviewed by the supervising electrician before installation proceeds. | Low | Licensed Electrician / Electrical Engineer |
2.Switchboard modifications and circuit installation
| Hazard / Risk | Initial Risk | Control Measures | Residual Risk | Responsibility |
|---|---|---|---|---|
| Electric shock during switchboard modifications | Catastrophic | Implement LOTO on the circuit being modified and any adjacent live circuits within reach inside the switchboard. Conduct Test-Prove-Test verification of isolation before opening the switchboard. Wear arc flash PPE (minimum 4 cal/cm²) while inside the switchboard enclosure even after isolation, as adjacent circuits may remain energised. Install a physically distinct labelled circuit breaker for each EV charger circuit. Verify absence of voltage on new cable before connecting to the circuit breaker. Re-install all covers and shrouds before re-energising. | Low | Licensed Electrician |
| Incorrect cable sizing causing overheating and fire | High | Select cable size per AS/NZS 3008.1 based on charger rated current, cable run length, installation method, and ambient temperature derating factors. For DC fast chargers (typically 50–350 A), engage an electrical engineer to size the cable. Ensure cable route is entirely in conduit or cable tray with no concealed direct burial in areas subject to physical damage. Thermal survey the cable terminations with a FLIR camera after commissioning under 80% load for 30 minutes. Record cable sizing calculations in the compliance documentation. | Low | Licensed Electrician / Electrical Engineer |
3.EV charger mounting and physical installation
| Hazard / Risk | Initial Risk | Control Measures | Residual Risk | Responsibility |
|---|---|---|---|---|
| Charger unit struck by vehicles in car park | Moderate | Install a minimum 100 NB Schedule 40 galvanised steel bollard or engineered concrete wheel stop at each charger location to prevent vehicle collision with the charger. Bollard foundation depth minimum 500 mm in concrete-filled socket. Ensure bollard placement does not impede EV cable reach or connector access. Confirm bollard placement is compliant with the car park layout and does not obstruct fire egress. Use a charger model rated for outdoor or car park environment (IP54 minimum) where exposed to weather or vehicle splash. | Low | Installation Supervisor / Site Supervisor |
4.Cable trenching and conduit through slab or walls
| Hazard / Risk | Initial Risk | Control Measures | Residual Risk | Responsibility |
|---|---|---|---|---|
| Cutting through post-tensioned concrete during core drilling | Catastrophic | Before core drilling or chasing any concrete slab or wall, obtain structural drawings and confirm the location is free of post-tensioning tendons. Where drawings are unavailable, engage a structural engineer to scan the slab using GPR (ground-penetrating radar) or cover meter before drilling. Mark the safe drilling zones on the slab surface. If a post-tensioning tendon is cut, immediately evacuate the area and contact the structural engineer — the slab may require propping. Never assume any concrete slab is conventionally reinforced only. | Low | Licensed Electrician / Structural Engineer |
| Silica dust exposure during concrete core drilling | High | Use wet core drilling for all concrete slab penetrations. Connect water supply directly to the core drill bit. Where wet drilling is not practicable, use a vacuum shroud with a HEPA-filtered vacuum on the drill. Workers must wear a fit-tested P2 respirator for all dry concrete drilling. Conduct air monitoring for RCS if drilling is conducted in poorly ventilated areas (e.g. basement car parks). Clean up slurry and drill cuttings immediately with wet methods — do not dry sweep. | Low | Licensed Electrician / All Workers |
5.Commissioning and testing of EV charger
| Hazard / Risk | Initial Risk | Control Measures | Residual Risk | Responsibility |
|---|---|---|---|---|
| Fault on EVSE causing electric shock to EV owner after handover | High | Commission each EV charger per the manufacturer's commissioning checklist. Test RCD protection trip time (must not exceed 40 ms at rated current per AS/NZS 3000). Confirm earth continuity of all metal enclosures and the vehicle charging cable earth conductor. Test charger communication protocol (OCPP, if networked) and pilot signal functionality. Attach compliance plate to charger showing installation date, electrician name and licence number, and test results. Issue Certificate of Electrical Safety and provide the building owner with the charger's operation and emergency procedures. Register the charger with the relevant network operator if required. | Low | Licensed Electrician |
