We appreciate the opportunity to provide this report for our work completed on September 11-27, 2023.

PURPOSE

The purpose of the project was to search for Fiber Lines and associated Communications Lines through all manholes and vaults within the project boundaries provided by the client. The scope of work consisted of 32 Manhole Locations and 19 Vault Locations. The utilities were traced out on site. Markings were applied around Manhole/Vault locations to show where the lines travel. Full mark-out of all Communications Lines located is shown on the Map below and separate .KMZ map.

EQUIPMENT

• Underground Scanning GPR Antenna. The antenna with frequencies ranging from 250 MHz-450 MHz is mounted in a stroller frame which rolls over the surface. The surface needs to be reasonably smooth and unobstructed in order to obtain readable scans. Obstructions such as curbs, landscaping, and vegetation will limit the feasibility of GPR. The data is displayed on a screen and marked in the field in real time.

The total depth achieved can be as much as 8’ or more with this antenna but can vary widely depending on the types of materials being scanned through. Some soil types such as clay may limit maximum depths to 3’ or less. As depth increases, targets must be larger in order to be detected and non-metallic targets can be especially difficult to locate. Depths provided should always be treated as estimates as their accuracy can be affected by multiple factors. For more information, please visit: Link

• Electromagnetic Pipe Locator. The EM locator can passively detect the electromagnetic fields from live AC power or from radio signals travelling along some conductive utilities. It can also be used in conjunction with a transmitter to connect directly to accessible, metallic pipes or tracer wires. A current is sent through the pipe or tracer wire at a specific frequency and the resulting EM field can then be detected by the receiver. A utility’s ability to be located depends on a variety of factors including access to the utility, conductivity, grounding, interference from other fields, and many others. Depths provided should always be treated as estimates as their accuracy can be affected by multiple factors. For more information, please visit: Link

• GPS. This handheld GPS unit offers accuracy down to 4 inches; however, the accuracy will depend on the satellite environment and obstructions and should not be considered to be survey-grade. Features can be collected as points, lines, or areas and then exported into

Google Earth or overlaid on a CAD drawing. For more information, please visit: Link https://www.gp-radar.com/350-400-mhz-gpr-antenna https://www.gp-radar.com/rd-8100-spec-sheet https://www.gp-radar.com/gprs-data-sheets

PROCESS

The process typically begins with using the EM pipe locator to locate pipes or utilities throughout the scan area. First, the transmitter is used to connect to and trace any visible risers, tracer wires, or accessible, conductive utilities provided that there is an exposed, metallic surface. The areas are then swept with the receiver to detect live power or radio frequency signals. Locations and depths are painted or flagged on the surface. Depths cannot always be provided depending on the location method and can be prone to error.

Initial GPR scans were then collected in order to evaluate the data and calibrate the equipment. Based on these findings, a scanning strategy is formed, typically consisting of scanning the entire area in a grid with 3’-5’ scan spacing in order to locate any potential utilities that were not found with the pipe locator. The GPR data is viewed in real time and anomalies in the data are located and marked on the surface along with their depths using spray paint, pin flags, etc.

LIMITATIONS

Please keep in mind that there are limitations to any subsurface investigation. The equipment may not achieve maximum effectiveness due to soil conditions, above ground obstructions, reinforced concrete, and a variety of other factors. No subsurface investigation or equipment can provide a complete image of what lies below. Our results should always be used in conjunction with as many methods as possible including consulting existing plans and drawings, exploratory excavation or potholing, visual inspection of above-ground features, and utilization of services such as One Call/811. Depths are dependent on the dielectric of the materials being scanned so depth accuracy can vary throughout a site. Relevant scan examples were saved and will be provided in this report.

FINDINGS

The subsurface conditions at the time of the scanning allowed for maximum GPR depth penetration of 1’-2’ in most areas. Multiple utilities were able to be located such as Electrical (Red), Communications (Orange), and Unknown (Pink). Using either the GPR or EM pipe locator. Some utilities were not able to be located such as Water (Blue), Gas (Yellow), and Storm/Sanitary (Green).

The following pages will provide further explanation of the findings.

CLOSING

GPRS, Inc. has been in business since 2001, specializing in underground storage tank location, concrete scanning, utility locating, and shallow void detection for projects throughout the United States. I encourage you to visit our website (www.gprsinc.com) and contact any of the numerous references listed.

GPRS Scanned and marked out all locatable Fiber lines and Communications lines throughout the VA Montrose Property. The Lines were primarily located using the EM Pipe Detector to trace a line that had been induced with a signal from the EM Transmitter device.

Lines were marked as “Duct Bank” because most of the lines were observed to be Duct banks that contained multiple types of

Communications lines including Fiber Lines. The initial scope consisted of approximately 30 manholes as marked on the plans provided by Triple C. As GPRS scanned through the area, additional manholes were discovered and added to the Scope of Work. These manholes were Manholes 22E. These were named based off of the branch that they seemed to come from. Further scans also identified a system of Vaults that appeared to connect to the communications Manholes. Many of these vaults appeared to contain Lines that may have been associated with the Fiber Lines. After consulting with Mat Perkins from Triple C, the decision was made to add those to the Scope of Work as well. The Vaults were labelled in reference to the closest manhole to them or to the branch of manhole that they extended from. GPRS was unable to confirm if the Vaults had an association with the Fiber Lines. The Vault lines appeared to travel in conjunction with Electrical Manholes that were not traced. GPRS was not able to find a source to the Vault lines as they appeared to tie into the

Manhole lines at Manhole 16 and Manhole 24

GPRS was able to identify two unknown manholes coming from the Main Entrance of the site and connecting to Manhole 22F. These manholes were unable to be full traced as they were in the middle of the road and traffic could not be safely diverted for long periods of time. The signal from these lines appeared to disappear near the main road by the front entrance. This signal end was marked with

“End of Information (EOI)/?”. Any item marked with “EOI/?” may continue past that point. Proceed with caution.

All lines running from Manholes/Vaults varied in depth from 1’-4’ throughout the site. Approximate depths were provided in the pictures associated with the penetration directions. GPRS reminds you that all depths are approximate and may vary on site. GPRS recommends scheduling a full utility mark-out prior to beginning any field excavation to identify any additional items that may be present near the Communication lines.

GPRS also conducted a full utility mark-out behind Building 7. GPRS marked out all locatable subsurface items within the Scope of

Work in this area. GPRS used a mixture of the EM Pipe Detector in both Active and Passive modes. Items located with the EM Pipe

Detector include Electric (Red). Where possible, GPRS provided an approximate depth of these lines on the separate .KMZ map. The

GPR was also used in this area with an approximate depth penetration of 1’-2’. These items were marked in Pink. No additional utilities were found in this area. Proceed with caution.

In the rear of Building 14, GPRS used the Duct Rodder to attempt to trace a spare conduit running from a transformer inside the building to an Electrical Manhole. GPRS sent the Rodder as far as possible into the conduit and traced it with the EM Pipe Detector.

GPRS was unable to determine whether or not the empty conduit was traced for the extent of the line or if it ran into an obstruction along the path. GPRS suspects that it is possible that the Rodder signal bled off onto the other Electrical lines running with it. The

Suspected bleed off point was marked on the separate .KMZ map. Proceed with caution. GPRS recommends calling the VPI (Video Pipe

Inspection) division of the company in order to confirm whether or not the conduit is clear or contains any breaks/obstructions.

GPRS reminds you that all depths are approximate and may vary beneath the surface. GPRS recommends keeping all excavation equipment stay a minimum of 1’-2’ off all marks. If it is necessary to go through a mark, please hand dig and expose the item in order to confirm item type, depth, and direction. Thank you.

GPRS appreciates the opportunity to offer our services, and we look forward to continuing to work with you on future projects. Please feel free to contact us for additional information or with any questions you may have regarding this report.
