GEOTECHNICS

 

Geotechnical study, part of the technical project (PT), required by the law 50/1991 (updated) regarding the authorization of the construction works execution, is in content and checking governed by NP 074-2007 Normative (“Normative regarding on geotechnical documentation for constructions”).

 

Geotechnical investigations:

  • Geotechnical drillings and testing wells with water sampling and testing of soil / rock;
  • Penetration surveys: standard dynamic penetration in boreholes (SPT); light dynamic penetration (DPL), heavy (DPH), super-hard (DPSH); cone penetration (CPT and CPTU);
  • Drillings equipping and permeability tests;
  • Drillings equipping and geophysical measurements (micro-seismo logging - MSC);
  • Drillings equipping as piezometers and groundwater level monitoring;
  • Other in-situ investigations (attempts with plate, pocket penetrometer, a.s.o.)
  • Investigations by indirect methods (geophysical): electrometry (SEV, ERT) and seismics (SR, DHT);
  • Laboratory determinations: geotechnical laboratory for establishing the physical and mechanical parameters and chemistry laboratory for determining the aggressiveness to concrete and metals;
  • Technical specialized assistance during the investigation, execution and operation period.

Geotechnical documentations:

  • Preliminary geotechnical approval for preliminary design phases (pre-feasibility / feasibility);
  • Geotechnical study for the other phases of design (DTAC / PT / DE / Unique Phase);
  • The geotechnical documentations runs for any type of civil and industrial construction, power plants, hydro-energetical settlements, urban constructions and municipal services roads infrastructure, land improvements, waste deposits, wastewater treatment plants.
