Field research
All testing, research and sampling are carried out according to the rulebook on building structures – Eurocode 7, Eurocode 8 and valid standards.
GEOMECHANICAL TESTS:
- Mechanical borehole drilling and sampling of disturbed and undisturbed soil and rock samples according to SRPS U.B1.010 and SRPS EN 22475-1 standards
- CPT test – Static penetration test
- CPTU test – static penetration with pore pressure measurement
- SPT test – Dynamic penetration test
- Installation of piezometer construction and hydrogeological testing of the borehole
- Automatic measurement of underground water level, temperature and electricity
- Conductivity
- Excavation of trial pits
- DCP test – field determination of CBR value
- Determining the compressibility modulus using the circular plate method
- Determining the modulus of deformation using circular plate loading
- FWD – Measurement of pavement structure deflections
- Detailed engineering-geological mapping of the borehole core and soil from the pits
- Selection, collection, packaging and transport of samples
- Detailed engineering geological mapping of the research area
- Professional design supervision during the execution of field works
GEOPHYSICAL TESTS:
- Seismic microregionization of terrain
- Geoelectrical tests of the terrain
- Refraction method
- MASW – multichannel analysis of surface waves
- HVSR – determination of the fundamental frequency of ground oscillation
- Down hole – seismic logging
- Data processing with report creation
