Geotechnical studies for the proposed construction of Wind turbines project at Rubessa, Wangdue

Bhutan Power corporation limited initiated with renewable energy power plant (wind energy) construction at Rubesa, Wangdiphodrang. APECS was awarded to conduct detailed geotechnical subsoil investigation for the proposed wind power plant.

Following were the major scope of the assignment:

  • Conduct core drilling in various location to determine the vertical section of the soil strata
  • Carry  out plate load teas to establish the stress-deformation of the top layers
  • Identify and assess the strength of geological materials by conducting necessary field and laboratory tests, chemical test and analysis.
  • Submission  comprehensive geotechnical report.
