InfraMarker RFID Monuments

Berntsen InfraMarker RFIDs are utilized at verified utility locations where Bravo has potholed (“daylighted”) using hydro and vacuum excavation trucks.  Projects have included verifying the location of the following utilities:

InfraMarker underground RFID tags are Omni manufactured passive, Class 1 Gen 2 standard RFID tags, with attached stainless steel backing plates and magnets (patent pending). The tags have been selected and tested by InfraMarker to deliver the best performance for underground reading using UHF and all are enabled with magnets for easy locating.

Bravo Environmental NW has installed hundreds of Berntsen InfraMarker RFID units on several projects for our clients, including the City of Bellevue, Sound Transit, and King County Housing Authority.

In the past, locating deliverables were limited to recording the location with a nail or whisker placed at the site, and the measurement results would be recorded on spreadsheets, site maps, and with digital pictures, but with the InfraMarker system, Bravo is now able to capture the entire deliverable (measurements, utility type, and photos) where it can be accessed not only from a remote “cloud” database, but also by any of the project’s stakeholders on the job site, and in real time.

This technology has caused a major breakthrough by eliminating the time spent by office staff on tasks that can now more easily and accurately be completed by field crews.  More importantly, for stakeholders and end-users of the data, the InfraMarker’s benefits make an even bigger difference, as the data collected is more reliable, easier to access, and remains on-site for as long as the utility remains in the ground.

The many stakeholders on utility projects are now free from the all-too-common occurrence of having to hire multiple hydro or vacuum excavation service contractors to complete the same pothole locates at the same job sites for construction phases which are sometimes only several years or even months apart.  That is, additional independent pothole or daylight locates are no longer required for each phase of a project, because the verified locating data is now stored permanently on-site on each marker’s RFID chip.

The time and materials-related cost savings this technology enables, and the redundancies avoided at job sites, are quite significant, and so are the added assurances and risk reductions from its enhancements to safe digging practices.  This makes the InfraMarker an invaluable innovation.
