Many projects require comprehensive site investigations for information to enable engineering assessment and design to proceed.  Opus’ geotechnical engineers, engineering geologists and laboratory technicians have extensive skills and experience in such investigations.

An initial site reconnaissance can identify issues, provide an initial assessment and provide the basis for subsurface investigations for a project. 

Geotechnical site investigations can include a wide range of activities, including:

• Cone penetrometer tests to measure ground strength
• Test pits and drill holes to obtain samples and profile ground conditions
• Geophysical testing to provide information on distribution of soil and rock materials
• Physical tests to measure material properties
• Extensive laboratory testing of material samples recovered from the investigations, often with all investigations locations surveyed
• Compilation of site maps, an important element of field investigations
• Investigation of existing structures and buildings  

Factual reporting of investigations is crucial part of the investigations process, as  accurate reports are essential to the subsequent engineering activities. The forensic aspect to these investigations can often be very challenging.
