Civil Works & Substations

Turnkey civil works for substations and grid infrastructure

PKBC delivers the full civil works package on substation and grid infrastructure projects across England and Scotland, with HV electrical installation by others. One subcontract carries the site from first earthworks to an energised, snag-free handover.

Because we self-deliver blockwork, joinery, drylining, painting and firestopping, main contractors deal with fewer interfaces and one accountable team.

Scope of works

What our civil works package covers

Priced as one package or as standalone elements, to suit your procurement.

Bulk earthworks & platform construction

Cut and fill, stone platforms and access roads that set the site up for everything that follows.

Foundations & primary equipment bases

Reinforced concrete foundations and plinths for transformers, reactors and primary plant.

Transformer bunds & containment

Reinforced bunds and oil containment built to the specification and tolerances the plant demands.

Substation buildings & control rooms

Blockwork, precast and steel-framed buildings, including control and switch rooms.

Cable trenches, ducting & troughing

Cable routes across the platform: trenches, duct banks, troughing and draw pits.

Drainage & attenuation

Site drainage, attenuation and interceptors that keep the platform dry and compliant.

Fencing, security & finishing works

Security fencing, gates and the external finishing works that close out the compound.

Internal fit-out & firestopping

Partitions, ceilings, doors, decoration, anti-slip and acid-resistant floor paintings, and tested firestopping systems inside substation buildings.

Proven in live and remote environments

Substation work rarely happens on an easy site. Our crews travel, lodge and deliver where the grid needs them.

Island and remote logistics

Shetland's Gremista GSP 132kV substation meant moving crews, lodging and materials to an island site and keeping the programme running far from the usual supply chain.
