Operating model

How we mobilise crews.

Our core team in Jablonec n. N. consists of approximately 20 permanently employed specialists: site foremen, welders, ventilation fitters, cleanroom mechanics, project management, QA and administration.

For large projects we mobilise through a long-established curated crew network across the CEE region and the DACH area - country composition adjusted per project location and crew availability. Between 10 and 100+ mechanics per project, with German- or English-speaking site management.

This model keeps fixed costs low and mobilisation speed high - the standard in the EU mechanical subcontractor market.

Confidentiality

NDA discipline is part of our deliverable.

Our end-clients build plants whose locations, layouts and specifications are intellectual property. Renka is silent about them - publicly. Specific end-client names, project layouts, construction timelines and volumes are only shared in the prequalification dossier - or directly under NDA.

We do not treat this as a marketing secret but as a delivery attribute: our end-clients trust us because we do not speak about them publicly.
