Site Investigations for Mechanized Excavation Projects
Pages 10

Site investigations (geotechnical investigations) resemble blood tests. It involves taking a blood sample from a human body using a syringe. After the blood sample has been taken, it is bottled and labeled to be sent to a laboratory. Depending on what’s being checked, the sample is then examined under a microscope, perhaps with the aid of chemicals. The analysis report is written and the results are shared with the patient. The results can be stressful and upsetting for the human. A wrong design and wrong parameters get the wrong answer. If the test and procedure are carried out according to standards there is no need to worry about the results.
