Miami Utility Locating Projects that Penhall Worked On

Locate gas lines with GPR

private utility locateA residential property owner contracted Penhall Technologies to locate a gas line. This line ran from an underground storage tank (UST) to a generator.  The area was being trenched out to run new plumbing. The house ran on electricity exclusively from a generator, so the owner wanted to dig safely.  With a 400 MHz GPR antenna and a utility wand, the analyst found the location and length of the UST. In addition, he found the location of the pipe that ran from the tank to the generator.  He then painted and flagged the lines, ensuring the location of the lines until she could get the project finished.

Radio Detection and GPR used to locate electrical lines, grade beams, and footers

The customer was renovating an existing restaurant and needed to locate live electrical lines under the concrete slab. The analyst used a RD7100 utility locating wand and transmitter to locate the electrical lines throughout the building. After, he marked the lines in spray paint. Because of this, the customer was able to saw cut the concrete without damaging the lines. In addition, Penhall Technologies used ground penetrating radar to scan for grade beams and footers.

Identify where all utilities are before installing new electrical linesPenhall Technologies Miami office was contacted to locate utilities in a parking lot in Miami, FL. The contractor was installing a new electrical line for a generator. A previous project had damaged a gas line in the area so the contractor was concerned about damaging utilities. Penhall Technologies used a 400MHz ground penetrating radar antenna along with a RD7100 utility locating wand to scan the areas as directed by the site contact. The analyst marked the findings on the surface with spray paint, which allowed the contractor to dig safely. GPR partnered with a utility wand is an accurate method to locate private utilities. GPR can scan to a depth of 3’-8’ depending on the soil conditions. The utility wand can locate live power along with other types of radio frequency signals.

private utility locating in miami floridaA contractor called Penhall Technologies to scan for private utilities at a Marina in Key Biscayne, Florida. The contractor was installing new drainage along with construction fencing and did not have any plans that showed the location of the utilities. The analyst was able to mobilize and scan the areas as needed using ground penetrating radar and a utility locating wand and transmitter. The analyst scanned the areas in a grid pattern to ensure complete coverage to locate any unknown utilities. The GPR antenna can locate utilities to a depth of 8’, while the utility wand can locate live power and can send a tone through exposed utilities. The analyst marked all findings on the surface with spray paint and flags. GPR is useful when trying to locate underground storage tankes and sub-surface voids.
