When mapping utilities in the complex built environment, it is important to have the proper tools and expertise. Subsurface Utility Engineering (SUE) is the process of mapping the utilities under your feet safely, before you dig. Complex distribution systems being utilized daily by millions can be hard to track, but geophysical tools like electromagnetic induction…
The Infrasense SUE Team is hard at work on subsurface utility mapping projects across Massachusetts. Leveraging advanced tools like 3D ground penetrating radar (3DGPR), EMI utility tracers, and other geophysical methods, we continue to support our client’s projects with accurate and comprehensive utility maps. If you have an upcoming project where we can be of…
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.
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…
In 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…
Infrasense completed a survey to both locate embedded utilities and determine pavement thickness of a three mile section of road spanning Warren and Bristol, Rhode Island. The survey was carried out using a nondestructive technology, Ground Penetrating Radar (GPR), and thus required no cores or test pits to obtain the necessary information. A majority of…
Infrasense completed a ground penetrating radar (GPR) survey to map the depth of steel reinforcing bars within the new Loon Mountain Resort bridge in Lincoln, NH.
