Integrated geophysical and geomatics site assessment for building extension planning at Clarkson university, Potsdam, New York

This project addresses the critical need for a comprehensive, multi-method site assessment prior to the proposed extension of a Center for Advanced Material Testing campus building, mitigating significant geotechnical and utility risks inherent in complex urban environments. Because only a limited number of boreholes can be utilized in projects due to financial constraints, there are undoubtedly dangers and a fair amount of uncertainty associated with geotechnical exploration. Depending on the experiences of the geotechnical engineers, these risks can be further raised or lowered. 

This research employs an integrated process of using advanced Geophysical and Geomatics techniques to map both the surface and subsurface conditions of the area of interest. Subsurface investigations utilized Ground Penetrating radar (GPR) at 450 MHz, which one was a Malar single channel and the other was an 18-channel 3D Raptor GPR antenna, supplemented by Frequency Domain Electromagnetic (FDEM), and Electromagnetic (EM) methods. This combination was essential for accurately locating ghosts and active utilities. Surface mapping incorporated UAV for aerial photogrammetry to generate precise Surface models and digital terrain Models, complemented by high resolution LiDAR and conventional topographical and As-built surveys. This model not only confirms the site’s geotechnical constraints and provides actionable data for foundation design but also establishes a reliable, risk-reducing protocol for future campus construction projects.
