From the preliminary planning through to the approval stage, we perform the planning and project drafting of high voltage overhead lines and cable routes. Our own personnel take care of all terrestrial surveying, laser-scan-data processing, negotiations with owners, technical calculations and plans. Our services also include variation analysis and feasibility studies.
