In the early planning and feasibility stages of a project, conducting a geotechnical desktop study can provide valuable insights into preliminary geotechnical information and professional opinions that contribute to the further development of the project.
A geotechnical desktop study involves accessing and analyzing general site conditions using a range of relevant information. This includes published maps, images, previous documents and reports, as well as available geotechnical data in the vicinity of the project site. The local experience and expertise of the geotechnical professional, especially from similar sites, also play a crucial role in this study.
The primary objective of the desktop study is to gain a comprehensive understanding of the site's geotechnical characteristics, identifying potential risks, challenges, and opportunities. The findings and recommendations derived from this phase serve as a basis for advising the client on the next steps, which often involve detailed site exploration and soil testing.
Following the desktop study, the next phase typically entails conducting field investigations to obtain more precise geotechnical data. This includes collecting soil samples, conducting laboratory tests, and performing in-situ measurements. The data obtained from these investigations forms the basis for engineering analyses and design calculations that support the project.
By investing in a geotechnical desktop study, clients can benefit from early-stage evaluations that help shape project plans, identify potential constraints, and inform decision-making. This proactive approach ensures that the subsequent engineering and construction processes are well-informed, efficient, and tailored to the specific geotechnical conditions of the site.
Geotechnical exploration and soil testing play a crucial role in obtaining site-specific soil and groundwater data. These activities provide valuable insights into the subsurface conditions, enabling us to make informed engineering decisions.
