Infrasense is out in Western Massachusetts recently completing a comprehensive evaluation of a bridge, including GPR, impact-echo, hammer sounding, and rebound hammer testing on all pier caps, columns, and abutments. The nondestructive testing data will be used to provide detailed maps and quantities of the substructure element conditions. If you have an upcoming project where…
DetailsIn 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…
DetailsInfrasense 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…
DetailsInfrasense 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…
DetailsInfrasense 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…
DetailsIn June of 2022, Infrasense performed an SUE QL-B survey to map the location of underground utilities of known and unknown origin along 2 miles of Route 16 in Mendon, Massachusetts. The survey included the use of GPR and EMI tools as the primary detection instruments and GPS for positional accuracy. The infield-located utilities, combined…
DetailsInfrasense recently completed nondestructive testing of a concrete tunnel liner using various NDT methods. The objective of this testing was to assess the condition of the concrete and confirm the presence of grout behind the liner. If you have any upcoming projects where we might be able to help, we’d be happy to hear from…
DetailsInfrasense was recently in Connecticut completing nondestructive testing to map elements of an unknown bridge foundation, including the footing and underlying piles. If you have upcoming projects where having bridge as-built information would be useful, we would be happy to help!
Infrasense is off to a busy start in 2023! We kicked things off with our annual company retreat the first week of January where we had sessions on internal R&D, equipment, software, new capabilities, project execution/ management, and other topics. The following week a group of us headed to Washington D.C. for the Transportation Research…
DetailsInfrasense just completed data collection for a concrete structure evaluation project on a building in Revere, MA. Ground penetrating radar was used to scan over 50,000 sq. ft. of concrete slab, spanning several floors. Data collected will be used to identify the spacing and depth of reinforcing steel bars and identify other targets such as…
