• Designing geotechnical alignment maps   for tunnel and underground structures and   geotechnical classification of rocks by drilling down to tunnel elevation to obtain needed data, defining excavation and palting methods.

• Foundation investigation of central, factory,   silo, viaduct, bridge piers and big buildings   and geotechnical evaluation of foundation   soil.

• Designing geotechnical maps of highway,   state road and railway alignments,   determining properties of foundation soil   by trial pits, drillings and tests, proposing   solution alternatives for ground water,   natural and artificial slope stability   problems.

• Determining soil properties of filling   material, classification of excavation   material, determining volume and properties of infrastructural material,   designing superstructure project and   geotechnical evaluation for highway   design.

• Evaluation of foundation investigation of   airports by drillings and in-situ tests.

• Determining quality and thickness of   sediment for harbour, quay, breakwater,   determining depth of basement rock and   obtaining engineering data by evaluating   the results for foundation project.

• Determining the most appropriate site for   
  built-up area by geotechnical and drilling   works,   proposing solution alternatives   about   environment and natural disasters,   investigating the possibility of assuring   water from ground or surface, performing   geotechnical works for internal and   external roads, determining reserve and   properties of appropriate material .

• Damage determination of buildings,   reinforcement against earthquakes and   reperation tests, sampling from carrier   systems, defining the equipment and   properties, direct shear tests for   concrete,   cracked corrosion, preparing the   proposal   report.
