The electrical implementation work includes the following activities:

  • Designing the addition's 3D model (Catia)
  • Calculations of sags, bus-ties and auxiliary services
  • Preparing technical specifications
  • Preparing all addition and disassembly drawings for the call for tenders and the construction site work
