After an initial evaluation, T2 recommended a phased data collection approach. Historic maps were reviewed in relation to the current site infrastructure to better understand the cemetery layout. Using Leica C10, a terrestrial laser scan was made of the buildings and open spaces. This technology captured millions of 3D data points in high-resolution digital color imagery to provide a realistic and accurate representation of the area.
Once the terrestrial laser scanning data was combined with the 1901 cemetery map, T2 used Stream C Multichannel GPR (MCGPR) to capture 3D data of the subsurface features in real-time using RTK GPS. The data was processed to detail the differences in subsurface conditions allowing the forensic specialists to focus their investigations and resources on particular areas within the project site. The approaches and technology that T2 Utility Engineers used in this investigation were successful in providing information of value. This project highlights the comprehensive underground information that can be used to efficiently identify underground unknowns. Contact us to learn more.
