Civil Works & Electrification

Bulk earthworks, foundations, control rooms, earthing systems and overhead lines from 11kV to 132kV for substation projects.

HVT’s civil and earthworks teams prepare and complete the substation platform, from bulk earthworks and drainage to reinforced concrete, control rooms and yard finishes.

Earthing systems and electrification work, including 11–132kV overhead lines, are delivered alongside the civil scope.

HVT lists “Electrification” as a service. The scope above is drawn from its civil, earthing and site-services pages.
