TABLE OF CONTENTS An important part of geotechnical engineering is laboratory testing. The laboratory testing usually begins once the subsurface exploration is complete. The first step in laboratory testing is to log in all the materials (soil, rock, or groundwater) recovered from the subsurface exploration. Then the engineer prepares a laboratory testing program, which basically consists of assigning specific laboratory tests for the soil specimens. Figure 1.1 presents an example of a laboratory testing program sheet.
