Through extra diligence with their utility designation process, contractor EXARO Technologies Corporation found an unmarked gas main and averted a disastrous gas explosion.

EXARO Technologies Corporation averts disaster with their careful utility locating process.

We got really lucky; we were going to drill with an excavator mounted ho-drill in that location the following day

EXARO Technologies Corporation, a Bay Area general engineering contractor, was recently hired by a contractor to verify utility locations (known in the industry as “to pothole”) as field marked by utility owners prior to their drilling. Using their utility designation techniques, EXARO Technologies Corporation discovered the unmarked 20” transmission gas main right where a drilling rig was scheduled to start the next day. The transmission gas main was not marked within the USA zone. The EXARO team’s extra diligence averted the tragedy of an exploding gas line.

“We got really lucky; we were going to drill with an excavator mounted ho-drill in that location the following day,” said the hiring contractor with relief.

The EXARO team was potholing for a telephone line marked within the USA zone, but did not find it per the utility owner’s marks. The EXARO team took the next step in their quality control process, which is to perform their own utility designation activities. During the process, they did not get solid response from equipment, but rather unusual results which let them to believe something was below even though they could not get a solid detect/locate on it. They attempted two additional potholes and found the unmarked 20” transmission gas main. Had they not discovered it, disaster could have befallen the drilling rig that was scheduled to begin drilling in that exact spot the next day and severely crippled transportation infrastructure.

As a result of this incident, EXARO Technologies Corporation has implemented a new process throughout their work areas in Northern and Southern California in an attempt to close the gap that may exist. This process will help EXARO prevent future catastrophic events and save lives.
