Trench for a medium-voltage cable line

For general contractors

The power package of your project — in safe hands

We take on the full electrical scope or selected works — cable lines, directional drilling, utility relocation, junctions and substations. With our own plant and documents ready for acceptance.

What a GC needs

A subcontractor you don't have to worry about

A general contractor answers to the investor for the whole project, so above all it needs predictability from a specialist subcontractor: deadlines met, independence on site, knowledge of the network operator's requirements and complete documents that let acceptances close without delay.

We have already completed four referenced contracts for contractors working for network operators: two for ZILINSKIS and two for PIWOWARSKI. The shortest — building 2,350 m of 15 kV cable line in Bolewice — took 18 days, from 25.11 to 12.12.2024. In every reference the client confirmed the works were carried out properly, within the agreed deadlines and without defects.

Fitting your programme

We plan our works around the stages of the whole project and the outage dates agreed with the operator.

Our works manager runs the electrical package and reports progress to your site manager.

Infrastructure clashes

On road, rail and building projects we relocate clashing MV and LV networks — utility relocation.

You can subcontract us for directional drilling only, cable laying only, or jointing and junction installation.

Questions

Questions from general contractors

Can you take on just part of the scope?

Yes. We deliver the full electrical scope or selected works — for example directional drilling only, cable laying, jointing and terminations, or setting junctions.

How quickly can you mobilise?

That depends on our current workload and the scope. We confirm the mobilisation date in our quote and fix it in the schedule once the contract is signed.

Do you provide materials?

As per the contract — we work with client-supplied materials or deliver them through our equipment supply service.

Who deals with the network operator?

By agreement with you, we take over day-to-day contact with the operator on outages, connections and technical acceptance of our scope.

Where do you work?

Across Poland. So far we have run contracts in the Lubuskie, Greater Poland and Kuyavian-Pomeranian voivodeships; our office is in Kraków.
