Site Engineering

Geological Surveys

ENVY offers detailed engineering services for understanding the geological structure of the power plant sites.

These services include:

  • Offshore drilling works
  • Onshore drilling works
  • Opening trenches and trial pits
  • Preparation of geological maps
  • Preparation of geological cross-sections
  • Geomorphological studies
  • Petrographic analysis

  • Preparation of geological logs
  • Remote sensing studies
  • Active tectonic studies
    • Paleoseismology
    • Archeoseismology

Geotechnical Surveys

For the assessment of sites in terms of engineering geology and in order to define necessary parameters for the design of the structures, detailed geotechnical surveys includin the following are conducted:

  • In situ measurements related to engineering properties of geological units, i.e. pressuremeter and dilatometer measurements, SPT, CPT, etc.
  • Taking disturbed and undisturbed core samples from boreholes and/or trenches
  • Conducting geotechnical laboratory tests both on rock and soil samples
  • Conducting field geotechnical tests such as field shear strength tests, plate load tests, etc.

ENVY has been providing top-notch engineering and project management services since 1999.
Site Selection and Characterization Studies has been carried out for the most important international projects in the region from pipelines to power plants including Nuclear.

Geophysical Surveys

ENVY provides detailed geophysical services in order to complement the geological studies and provide information for the physical conditions of the site.

These service are grouped under two main topics:

Surface Geophysics

  • 2-D electrical profiling,
  • 3-D electrical measurements
  • VES (vertical electric sounding)
  • SP (self potential) measurements
  • Seismic refraction (ReMi, MASW, MAM) measurements
  • Microgravity measurements
  • Microtremor array
  • Geomagnetic measurements
  • Offshore deep seismic measurements

Borehole Geophysics

  • Electrical Logging (resistivity, thermometry, caliper)
  • Radioactive Logging (natural, gamma-gamma, neutron-neutron)
  • Seismic Logging (acoustic, downhole, PS)
  • Cross-hole seismic/electric measurements
  • HiRAT measurements

Hydrogeological Surveys

Hydrogeological surveys carry crucial importance for the evaluation of the power plant sites. In the scope of these surveys, ENVY conducts following studies:

 

  • Designing, drilling and developing of pumping and piezometric boreholes,
  • Hydrological (level, conductivity, temperature, etc.) and chemical monitoring studies,
  • Karst hydrology studies,
  • Preparation of the hydrogeological maps,
  • Hydrogeological modeling studies.

Meteorological / Aerological Surveys

ENVY conducts studies for the evaluation of the meteorological and aerological conditions of the sites.

These services:

  • Establishment of sodar-rass and meteorological stations with various heights
  • Continuous operation and monitoring
  • Assessment of past and current meteorological/aerological conditions of the site
  • Dispersion modeling studies
  • Evaluation of rare meteorological hazards like tornado, lightning etc.

Geodetic Surveys

ENVY offers a wide range of geodetic services including the geodynamic level measurements which also to complement the monitoring of the seismic activities of the region.

  • Laying of geodynamic polygon benchmarks and points
  • High precision leveling measurements
  • Satellite measurements
  • Mapping studies using classical methods and aerial and/or lidar imaging
