In August of 2022, Infrasense performed an SUE QL-B survey to map the location of underground utilities of known and unknown origin adjacent to the Church Street bridge crossing Fall River in Bernardston, Massachusetts. The survey included the use of GPR and EMI tools as the primary detection instruments and GPS for positional accuracy. The…
Infrasense recently completed a subsurface utility engineering (SUE) project on Dorchester Avenue in Boston, MA. The initial phase of the project included reviewing existing site drawings (QL-D) and a site survey to identify the location of relevant site features (e.g., water valves, fire hydrants, manholes, and telephone poles (QL-C). The second phase of the project…
Infrasense recently completed a subsurface utility engineering (SUE) project in the vicinity of the four vent buildings that service the Sumner and Callahan Tunnels in Boston, MA. The project involved reviewing availability site drawings (QL-D), confirming the location of the site features (e.g., water valves, catch basins, manholes) (QL-C), and locating known and unknown utilities…
Infrasense completed a subsurface utility mapping project at a large industrial park in Tyngsboro, MA using a combination of ground penetrating radar (GPR) and electromagnetic induction (EMI) locating methods. The GPR equipment included a 400MHz ground-coupled antenna mounted to a cart with an integrated distance encoder and GPS unit. This GPR antenna is capable of…
Infrasense completed a ground penetrating radar (GPR) survey to map the size and position of the steel reinforcing mesh within an undocumented pier extension at the Midway Airport in Chicago, Illinois
Infrasense recently completed a project using a ground-coupled vehicle-mounted 3D ground penetrating radar (GPR) system manufactured by 3D-Radar to identify subsurface structural objects that would impede future installation of sheet pile walls at the Brooklyn Army Terminal.
Infrasense and Radar Solutions International (RSI) have recently completed utility mapping at two liquid natural gas facilities in northeastern Massachusetts.
