Scanning 1.5 acres in Knoxville, TN at University of Tennessee Medical Center

The GPRS East Tennessee office was subcontracted by an engineering firm out of Knoxville, TN to scan approximately 1.5 acres in Knoxville, TN at University of Tennessee Medical Center.  The firm was interested in collecting soil samples for analysis.  UT Medical Center was interested in expanding their chiller capacity, which is currently stationed on a roof top.  There were 6 locations that needed to be scanned in the rear parking lot with ground penetrating radar so that underground utilities would not be struck when the drilling took place.  The GPRS representative used a GSSI 400 MHz antenna and a radio detection wand to scan these 6 locations over multiple surfaces and terrain conditions.  Each location to be drilled was scanned in a 10’x10’ radius, and bordered with white paint on the surface so the drilling contractors could better understand the exact boundaries of each area scanned with ground penetrating radar.  There were multiple utilities and areas of interest found on this site, and upon location, each utility and area of interest was marked on the surface with paint indicating what type of utility was encountered.  Depths were provided if located with ground penetrating radar.  All findings were reviewed with the site contact after the ground penetrating radar inspection and any locations that had to be moved due to utilities in the direct path were communicated with the site contact.  Details of the inspection were also reviewed with onsite personnel so that they could update their site drawings for their records.

The 400 MHz transmits an electromagnetic pulse through the ground and displays the reflection on a SIR 3000 head unit for interpretation.  This antenna allows for ground penetrating radar signal penetration of 4’-7’ through the ground in the southeast region of the United States.  Radio Detection RD-7000 locator is a device that detects live power and RF signals underground, allowing us to locate electrical or telephone lines even if they are below the minimum size requirements to be detected by ground penetrating radar.  It also allows us to detect utilities via frequency induction or conduction with an exposed or known surface of the conductive utility.
