Firstly
Site soil investigation tests that extracting samples from water, underground water and rocks for the purpose of:
-determine the perfect foundation type of the origin.
-determine the chemical properties of the soil and rocks for the purpose of determine the safety of the foundations .
-measuring the level of the underground water by set drilling test with different depths in the clay , gravel or sandy soils.
Secondly:
laboratory soil test in the branches center in Baghdad , Babel ,Basra and Kirkuk .
-plastic limit test
-liquid limit test
-long shrinkage factor test
-triaxial compression test
-unconfined compression test
- moisture content
-granular
-seive analyzer by hydrometer test
- free swelling
-dry and wet density test
-permeability test
-direct shear test
-consolidation
-specific gravity
Thirdly:
Made the geophysicist surveys which successfully used in civil engineering acts in last years , the center taken the lead to solve like this problems by electric and seismic surveys to determine :
-weak areas in the soil.
-determine the gaps under the foundations by specialist devices.
-determine the electric quilative resistance which assiste to find the level of the underground water .
