Bolt Key Takeaways

  • Client retention: Re-selected by SPECBAU for a flagship industrial build, demonstrating long-term trust.
  • Engineering fluency: Precise handling of structural steelwork, MEP/HVAC systems, and electrical engineering terminology.
  • Site alignment: Interpreting at regular Jour Fixe coordination meetings between the German investor and Polish main contractor.
  • Documentation: Translating technical specifications, site acceptance reports, and Requests for Information (RFIs).
  • Mediation: Bridging communication gaps and resolving misalignments in a high-pressure construction site environment.

Greenfield investment: a high-stakes construction project

In autumn 2022, construction began on one of the renewable energy sector's flagship investments in the Legnica Special Economic Zone (LSSE). German heating technology giant Viessmann broke ground on a state-of-the-art heat pump manufacturing plant. SPECBAU Polska — a general contractor I had successfully partnered with on previous builds — was appointed to lead construction.


SPECBAU's decision to re-engage my services was a clear vote of confidence. In commercial construction, where tight schedules and substantial liquidated damages leave no margin for communication errors, reliable language support is mission-critical. Their trust was earned through a proven track record of precisely translating complex engineering challenges.

From groundwork to topped out: site reality

My role extended beyond standard interpreting; I served as the primary communication bridge between the general contractor and the German investor's site supervision team. I provided continuous interpreting at weekly Jour Fixe site coordination meetings, where project milestone progress, schedule adjustments, and design clashes were negotiated.


Construction interpreting demands absolute precision: technical terms such as "C30/37 grade concrete", "steel fiber reinforcement", or "perimeter expansion joints" must be rendered flawlessly. Alongside oral interpreting, I translated detailed executive engineering documentation — spanning material submittals and technical data sheets to MEP acceptance reports. The project demonstrated how language barriers disappear when backed by specialized technical communication expertise.
