In civil engineering, highly qualified geotechnical experts take part in the project edition and in the rest of the stages until the works are complete reviewing the previous hypothesis and updating the design whenever it is necessary. However, in building works Geotechnics are normally reduced to the basic Geotechnical report and any design decision (i.e. Type of retaining structures, lowering of the water level, etc.) is taken by non specialized professionals. This management model is explained in the forthcoming fashion:

Regular Management Model:

                        High control over the structure:

• Accurate normative.
• Properly defined materials and sections.
• Accurate calculation methods.
• Each indetermination is redesigned and recalculated.
• Exhaustive controls of the stress-strain properties of soil during the execution.

Low control over the structure:

• General normative, contradictory, difficult to follow.
• Uncertain materials and sections.
• Approximate calculation methods and not consistent with each other.
• Soil is only studied in the first stage (Geological-Geotechnical study). Any indetermination is tackled by the project manager.
• Some complementary tests are sometimes performed during the execution of the project. They are sometimes analyzed by specialized professionals.
