Operation of a construction site quality control laboratory in the two state-of-the-art ultra-high voltage centers under construction, the Koumoundourou converter station and the Damasta converter station for the project “Crete-Attica electrical interconnection” where it is included in the top five of the most innovative direct current interconnection projects in Europe.

  • Determination of density in soils and pavements by nuclear methods and use of cone-sand method.
  • Concrete sampling and determination of compressive strength.
  • Soil sampling for laboratory tests (granulometric analysis, determination of atterberg limits, determination of maximum laboratory density – Proctor, determination of californian bearing capacity ratio, determination of organic substances)
  • Sampling of aggregates for laboratory tests (granulometric analysis, determination of plate index, determination of Atterberg limits, determination of maximum laboratory density – Proctor, magnesium sulfate test, sand equivalent, methylene blue test, fragmentation to resistance – Los Angeles.)
  • Determination of ground bearing capacity by plate load test
