Infrasense engineers recently conducted a ground-penetrating radar (GPR) survey along a segment of road in northeastern Massachusetts in order to map bedrock topography. In this case, GPR proved to be an effective tool in mapping bedrock stratigraphy to approximately 25-feet maximum depth penetration. If you have an upcoming project where we can be of assistance,…
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…
Infrasense is exhibiting this week at the 100th Annual North Eastern States’ Materials Engineers Association (NESMEA) meeting in Springfield, MA. We are excited meet with clients and colleagues to discuss using nondestructive evaluation (NDE) methods for mapping subsurface conditions.
Infrasense engineers performed ultrasonic testing along the parapets and spandrel walls of multiple bridges in the Boston area. The results of this testing will help to plan subsequent rehabilitation efforts. If you have an upcoming project where we can be of assistance, we’d be happy to hear from you. Please visit our contact page, or reach…
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 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…
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…
