Geotechnical studies represent the first stage of the construction, rehabilitation or strengthening of a civil or industrial objective. Documentation is an integral part of the technical design, required by Law. 50 of 29.07.1991 and updated. Geotechnical studies include information about physical and mechanical characteristics of the soil resulting in a series of recommendations on foundation solutions, technical advice necessary to issue future construction projects.
Preliminary geotechnical notice provides an assessment of the quality of land and can be used for early design phases – feasibility study, project urbanism etc. Geotechnical notice is drafted on the basis of existing geotechnical data or based on a small number of field investigations, depending on the importance and volume of investigation and does not replace the geotechnical study.
Geotechnical Studies
* Site recognition and documentation;
* Land Evaluation:
- geotechnical drillings;
- open surveys – ditches, wells;
- foundation unveiling;
- static penetration;
- dynamic penetration;
- plate test;
- geophysical investigations;
* Soil and water sampling;
* Laboratory analysis of collected soil samples (in order to identify the physico-mechanical properties and determine the aggressiveness of the water on concrete and metal);
* Preparing the geotechnical study by interpreting information from field and laboratory;
* Check the documentation prepared by an authorized expert MLPAT, AF requirement and drawing geotechnical essay;
* Geotechnical studies are prepared on the basis of norm NP 074/2007 for:
- transport infrastructure (road systems, bridges, tunnels, railway construction);
- civil construction;
- land reclamation;
- hydro construction;
- agro-zoo-technical building;
- industrial and commercial buildings;
- telecommunication infrastructure;
- urban construction and municipal;
* APPLICATIONS OF GEOPHYSICAL INVESTIGATIONS:
- Archeological Surveying
- Borehole Investigation
- Determining Geological and Hydrological Conditions
- Lake and River Prospecting
- Mapping Unexploded Bombs (UXO)
- Minerals Exploration
- Research on Inorganic Contaminants
- Utility and Buried Objects Detection
- Wind Farms and Photovoltaic Sites
* Other methods used in geophysical investigations:
