ounce of prevention could save your next project time and money
An environmental company in Newport News, Virginia hired GPRS to
assist at the site of a former gas station to locate unknown subsurface utilities
prior to constructing a new structure on the site. All too often, our client
has been told that the fuel tanks were removed from the property, even if it
isn’t the case. This type of faulty information can damage equipment, delay the
project and put your crew in harm’s way. The first step in the project was
an entire radar sweep of the property for any unknown storage tanks. Once it
was confirmed that there were no tanks on the site, the client needed to perform
a series of soil borings to check for soil contamination levels.
The environmental client called GPRS to come out and conduct scans
ten specific areas that he had previously marked out. The radar equipment that
was used on site was the 400 MHz/350 MHz antenna along with the SIR 4000 in a
2’ grid pattern to locate any and all possible underground utility lines in the
concerned areas. GPRS also scanned a 20’ area around each of the identified
marks and found out that several of the clients’ locations were inaccurately
placed. Our team was able to correct the issues, and scan the appropriate areas
to ensure there were no subsurface utility lines in the way of construction.
Using ground penetrating radar to locate utilities allowed the
project manager to see below the surface of the job site, and help locate several
non-conductive utilities that had gone unmapped by state 811 locators. In
conjunction with the radar scans, GPRS went back over the area using Radio
Detection to see if there were any live power or communication lines, visible using
the passive scanning mode procedure. By doing multiple passes with several
pieces of utility detection equipment, we were able to provide the client with
a full and accurate map of all the subsurface utility lines in the specified
The project manager made the standard marks as necessary: Red for
power, Yellow for gas, Blue for water, Green for sewage, Orange for
communications, Pink or White for unknown utilities. GPRS subsurface utility
scanning saved this particular client from hitting any of these critical
utilities, potentially saving the company from any costly repairs, down time,
and possible injuries that may have occurred if they had drilled without using
a private utility locating contractor. All GPRS employees are OSHA 10 trained
and go through up to 4 months of training to ensure they are extremely
comfortable with the equipment they are using and confident in their ground
penetrating radar skills.
Every construction or excavation project fights to maintain its
estimated schedule and budget. Contractors spend a significate portion of their
time in project scheduling meetings, making schedule revisions, and
communicating with owners about changes to the schedule. The last several years
have been a struggle in the construction industry and more than ever before the
schedule can have a direct impact on the bottom line.
Take some of the guesswork out of your
next construction project by utilizing the private utility locating services at
GPRS. We can keep your project on time, on budget and keep your crew safe from
subsurface hazards that may be lurking beneath the surface of your job site.
Remember, you are on the hook legally and financially for repairing any damage
to utility lines caused by your digging. Always call a private utility locator
like GPRS before you start digging on your construction site.
Ground Penetrating Radar is the industry’s preferred tool to
locate underground private utilities. GPRS has a 24-hour service and rapid response
team, and can be out to your job site often times the same day as your call. We
can get to any job you may have within 24-hours or less if needed with our
rapid response program. Contact your local GPRS unit for more information about
how GPRS can help you eliminate the unforeseen and keep your next construction
project on time and on budget.
