Infrasense had a great time this week at the Transportation Research Board (TRB) Annual Meeting, where we met with clients and colleagues, and attended several technical presentations and committee meetings. As is always the case with TRB, we left the meeting feeling inspired and excited for the future of the transportation industry!
Subsurface Utility Engineering (S.U.E.) requires working together to plan safe and efficient surveys, which often means overnight shifts to minimize interactions with traffic. In addition to traditional utility mapping tools, Infrasense can deploy vehicle-based ground penetrating radar as part of SUE projects to report other subsurface conditions including pavement layer thicknesses and moisture ingress/ voiding.
Infrasense was recently in Dallas, Texas completing GPR pavement thickness surveys on the City’s arterials and collectors. We are happy to be working as a subcontractor to IMS Infrastructure Management Services as part of a larger network-level survey of the City’s pavement conditions.
Infrasense was recently in the City of Toronto completing GPR pavement thickness surveys on over 2,800 kilometers of the City’s network. We are happy to be working as a subcontractor to International Cybernetics Company (ICC) as part of a larger multiyear network-level survey for the City.
Infrasense was in Missouri recently completing GPR, infrared, and visual scanning of bridge decks in the St. Louis area. Below are sample images in the early stages of processing. The final deliverables will present the infrared and visual imagery for the entire bridge deck with all areas of delamination, patching, and spalling mapped and quantified.
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…Details
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…Details
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…Details
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…Details
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…Details
