Radar Technology Used to Locate Conduits inside a Corporate Facility in Tempe AZ.jpg

Radar Technology Used To Locate Conduits Inside A Corporate Facility – Arizona

Prior to saw cutting concrete floor slabs, it’s essential to have as much information as possible in regards to what utilities may be below the surface. In many instances during construction of buildings, conduits & other utilities will be placed in the actual pour of the concrete floor or just beneath the concrete floor. The process will go much smoother if the areas are scanned with ground penetrating radar & radio detection prior to beginning the demolition process.

An electrical contractor took a chance with saw cutting an entrance area of the building without having it scanned first for any potential conduits. During the saw cutting they had cut through some electrical conduits that powered parts of the building. Before they continued to saw cut the areas they decided it would be best to investigate the floors for any more surprises. There were many unknowns as to what types & how many utilities were embedded in the concrete floor during the original construction. The building facilities didn’t have any records or drawings of what could possibly...

Ground Penetrating Radar Used to Investigate Outside for Utilities Prior to Digging a Trench at an Industrial Facility – Arizona

It’s essential to have as much information as possible before digging or drilling as to what utilities could be passing through underground. It’s even more essential when working inside an industrial facility with multiple electrical feeds passing through. The thought of digging, trenching or drilling prior to having a private utility locate completed, should never happen. The risk of injuries is too high.

A general contractor had a project where they needed to drill borings & trench throughout an industrial complex. It was unknown of the paths of any existing utilities passing through the area especially the electrical feeds. The general contractor had to connect the future electrical conduits to the existing electrical feeds. Prior to proceeding it was essential they had information to which direction the existing electrical was running so they could tie into it & also so they didn’t compromise it during the excavation process. The general contractor also needed to know if any other existing utilities were present before proceeding with the trenching...

Private Utility Locating – New Mexico

Ground Penetrating Radar Systems of New Mexico recently visited a church parking lot to identify any underground utilities in the area prior to excavation for a new building. Klinger Constructors wanted to ensure that there would be no delays in construction due to severed utilities.
