EV charging station construction involves civil works, electrical installation, and network connection for vehicle charging points.
Electrical installations range from single 7kW chargers to rapid 150kW+ units requiring high voltage supply connections.
Cable trenching across car parks and public areas creates excavation, pedestrian, and vehicle management hazards.
Electrical connections to the distribution network must be made by qualified, authorised electricians with proper isolation.
Existing buried services beneath car parks including drainage, lighting cables, and telecoms must be located before excavation.
Public-facing installations require barriers and signing to protect pedestrians from the construction work zone.
Concrete bases and equipment plinths involve formwork, reinforcement, and pour operations in restricted spaces.
Commissioning and energisation of chargers involves DC and AC systems requiring specific electrical competence.
Working in operational car parks means managing vehicle movements around the construction area throughout the works.
Grid connection upgrades may require work on high voltage equipment with associated arc flash and electrocution risks.

Electrical hazard	Rapid chargers operate at high voltages and currents — installation and commissioning require specific electrical competence and safe isolation.
Public interaction	EV chargers are installed in public car parks — construction must protect pedestrians and drivers from excavations and live work.
Buried services	Car parks contain buried drainage, lighting, and data cables — excavating without scanning causes service strikes and disruption.

Don't

Scan for buried services before excavating any cable trenches across the site.
Install barriers and signs to protect the public from the construction work zone.
Ensure only qualified, authorised electricians make electrical connections and terminations.
Follow safe isolation procedures for all electrical work on the charging installation.
Manage vehicle movements in operational car parks with banksmen and traffic control.
Support all cable trench excavations according to the ground conditions and depth.
Commission chargers using the correct procedures for the DC and AC systems involved.
Follow HV safety rules for any grid connection upgrade work on the distribution network.
Brief the team on public protection measures and the site traffic management plan.
Coordinate electrical and civil works to prevent conflicts and rework on site.

DON'T excavate cable trenches without scanning for existing buried services first.
DON'T leave the work zone unfenced or unsigned where the public can access it.
DON'T carry out electrical connections unless you are a qualified, authorised electrician.
DON'T work on charger electrical systems without completing safe isolation procedures.
DON'T allow uncontrolled vehicle movements around the construction area in car parks.
DON'T leave cable trenches unsupported or unguarded in public access areas.
DON'T energise chargers without following the full commissioning procedure and checks.
DON'T work on HV grid equipment without HV authorisation and arc flash protection.
DON'T let members of the public interact with partially installed charging equipment.
DON'T proceed without coordinating civil and electrical work sequences to avoid clashes.
