Ground Penetrating Radar Case Studies

SAFELY AND ACCURATELY FINDS AND CLEARLY PLOTS TARGETS IN THEIR EXACT LOCATION BELOW THE SURFACE IN CONCRETE OR SOILS

Ground-Penetrating Radar in Grand Rapids, MI

Ground Penetrating Radar in Grand Rapids, MI (GPR) is the safest non-destructive means in which to survey an area before construction modifications begin. Diamond’s GPR systems can scan walls, floors, and soils in many different conditions. GPR allows for the successful location of buried utilities including water lines, electrical lines, post-tension cables, gas lines, in-floor tubing, and voids that will be embedded within the concrete or soil. By scanning prior to any type of modification costly shutdowns and potential accidents can be avoided.

Diamond’s system for locating utilities in Grand Rapids, MI, can be used in almost any setting due to the low impact of the scan. The scanner signal is 1% of a cell phones’ output. GPR can be deployed quickly and effectively in the most confined areas. By employing GPR in certain areas where potential hazards exist you can eliminate the “guess” work and determine if an area can be safely modified. By conducting a scan costly mistakes are eliminated and work schedules are more productive due to the elimination of down time and replacement costs.

Proven knowledge, five decades of experience, immediate availability, safety, on-time completion and continuing innovation makes Diamond the sensible choice for ground penetrating radar services.

Client

Fishbeck, Thompson, Carr, & Huber

 

Project

Prior to excavation as a part of a repair project in front of historic Spartan Stadium at Michigan State University, the engineering staff needed to locate all utilities. In addition, they needed to know the depths of the utility lines in order to avoid unnecessary mid project design changes and/or damages to existing utilities during the excavation process. After location and identification all utilities were to marked and transposed to engineering drawings provided by the client.

Plan:
Diamond Subsurface Imaging developed a plan to survey of subsurface ground by using Ground Penetrating Radar—GPR SIR 20 systems, with Radan software and onsite 3D capabilities.

 

Process

Over a 5 day period over 7000 linear feet of Subsurface imaging was performed by a Diamond GPR technician. Using a 400 mHz antenna and radio frequency locating equipment Diamond Located and verified the depth all utilities in the scanned area.

 

Outcomes

By locating and verifying the depth of all utilities Diamond was able to deliver to FTC&H engineers integrated mapping of all findings. According to John Lefevre, FTC&H project manager; “This is one of many projects for which we’ve used Diamond Subsurface Imaging, as always they provided the high level results that we’ve come to expect from them.”

Client

Envirologic Technologies

 

Project

Envirologic Technologies is a regional environmental consulting firm with major municipal, commercial and industrial clients. An entity, contemplating the purchase of a parcel of land where at one time a gas station had existed, retained Envirologic to conduct an environmental site assessment. Envirologic needed to know if underground fuel tanks were still present or had been removed from the site.

 

Plan:
Diamond’s detailed plan included the surveying of the entire site—if tanks were to be found, their location would carefully mapped. By noninvasively mapping the presence of tanks prior to soil testing and excavation, the damage associated with tank rupture or hydrocarbon contamination of the ground and ground water can be greatly reduced.

Process

A Diamond engineer surveyed the entire 60,000 square foot parcel in a grid pattern using a 400 mHz antenna designed to clearly identify underground objects such as storage tanks. By noninvasively mapping the presence of tanks or other underground objects, the client was able to greatly reduce risk and expense associated with discovery during excavation or soil boring.

 

Outcomes

After five hours of scanning, three underground storage tanks were located. This allowed Envirologic engineers to test soil surrounding the tanks for contaminants—finding none, the tanks were safely removed. “We at Envirologic regularly use the services of Diamond on sensitive jobs like this one,” said David Stegink, project manager for the company. “Their professional knowhow, equipment and trained staff are some of the reasons we will continue to use them in the future.”

Client

Kent Companies

 

Project

The River House Condominiums, the tallest building in Grand Rapids, and the tallest all-residential building in Michigan opened to rave reviews in November, 2008. Prior to final construction, design changes needed to be made on most, of the 34 floors of the building. These changes necessitated that all post tension cables be located and mapped to avoid damage during the change process.

 

Plan
In consultation with the client Diamond developed a plan to non-destructively survey different locations on 30 out of the 34 floors in the building. The plan called for using Diamond’s Ground Penetrating Radar (GPR) SIR 20 systems, with Radan software and onsite 3D capabilities.

Process

Using a 1500 mHz antenna Diamond engineering staff spent over 60 hours structurally scanning over 100 different locations throughout the building—floors 1 through 30—verifying and mapping the location and depth of post tension cabling.

 

Outcomes

According to Paul Bowne, from Kent Companies, Diamond was always available when needed. “They were very responsive,” he said. “They conducted scans on 20 different occasions, always adjusting their schedule to ours, and always meeting the set timelines. By using Diamond,” conclude Bowne, “we avoided both, the potential for the massive expense of damaging post tension cable and for delaying completion of the project.”

Client

CH2M Hill (Enterprise Spatial Solutions)—Pfizer

 

Project

Core drilling of concrete walls, as a part of a project for mechanical penetrations, was planned for at Pfizer’s manufacturing facility in Kalamazoo, Michigan. However, prior to drilling, the project consultant, CH2M Hill, needed to locate the reinforcing steel inside the walls in order to preserve structural integrity and prevent damage to the site.

 

Plan

Diamond Subsurface Imaging developed a plan to survey all of the of the wall sub-surfaces by using Ground Penetrating Radar—GPR SIR 20 systems, with Radan software and onsite 3D capabilities.

Process

Diamond scanned 16 locations of 8” thick concrete wall on 4 different floors. A 2’x2’ area around each location was targeted to allow for core drilling location adjustments. Scans were completed using the 1500 mHz antenna (structure scan). Because of accessibility issues, 12 of the 16 locations had to be scanned using a lift operated by the Diamond Subsurface Imaging technician (MIOSHA certified operator). At each area, the actual locations of reinforcing steel were clearly identified and marked so that there would be no doubt as to their location.

 

Outcomes

By locating and verifying all of the steel reinforcement Diamond delivered to CH2M Hill a survey indicating areas free of reinforcement where holes could be drilled. According to Mark Jackson, CH2M Hill Project Manager, “Because Diamond had not performed a ground penetrating radar survey for us directly in the past, it was important that we evaluated their work thoroughly before the project. Diamond performed 16 radar surveys to locate reinforcing steel in an 8 inch thick concrete wall to insure that all the steel remained intact after core drilling. The radar surveys allowed the subsequent core drilling to be completed successfully and all reinforcing steel was avoided. Diamond’s technicians were professional throughout the project and their performance met all of our expectations. I have recommended to Pfizer that Diamond should be contacted again should radar services be required in the future.”

Client

American Electric Power

 

Project

AEP’s Cook Nuclear Plant, located along Lake Michigan’s eastern shoreline, in Bridgman, Mi, has been in operation since 1975. AEP needed to repair small ground water leaks in the walls and floors throughout the plant. Their repair plan included the Turbine Room, Screen House, and Auxiliary Buildings. The plan called for drilling eight inches into the concrete walls and floors around the problem areas and filling the cracks with a special compound to seal off the leaks. However, because of stringent engineering requirements, all concrete needed to be non-destructively imaged before any drilling could take place anywhere in the Cook Nuclear Plant. All reinforcement and conduits had to be located and mapped to drawings before any work could begin.

 

Plan

Diamond Subsurface Imaging developed a plan to survey and scan all the problem locations of the plant by using Ground Penetrating Radar--SIR 20 system, with Radan software and onsite 3D capabilities. Survey and verify the location of all reinforcement and utilities in the problem areas and map all findings to drawings for the team at Cook Nuclear. The use of Ground Penetrating Radar helped AEP avoid making contact with rebar and conduit embedded in the concrete they were repairing.

Outcomes

By verifying the location of all reinforcement and utilities in the problem areas, Diamond helped Cook personnel avoid making contact with rebar and conduit embedded in the concrete they were planning to repair. All drawings developed for Cook Nuclear Power Plan were completed to scale and submitted to the Plant’s Engineering Department.

Client

Joe Louis Arena People Mover—City of Detroit

 

Project

While conducting structural integrity testing on the parking ramp deck near the People Mover station at Joe Louis Arena, the home of the National Hockey League’s Detroit Red Wings, an electrical conduit was slightly damaged. The specific damaged conduit needed to be shut down without shutting down all the surrounding feeds which in effect would disable the entire Detroit People Mover.

 

Plan

The challenge was to determine with pinpoint accuracy which conduit was the damaged one so it could be isolated and repaired without impacting the operation of Detroit’s People Mover.

Diamond surveyed the area in order to determine which of the conduits was damaged. Using GPR (Ground Penetrating Radar) with 3D capability and Radan software technology, a Diamond engineer scanned the parking ramp area. The next day, Diamond provided a mapped-scan identifying the damaged conduit, showing its exact location and the control box it serviced.

Outcomes

According to Jason Duda, General Foreman of Detroit Electrical Services, LLC (DES), the project’s General Contractor, Diamond did a great job. “We completed the repairs and all went well at the Joe Louis Arena,” he said. “The GPR device Diamond used found the conduit under the concrete. This discovery saved the company a lot of time and money. Their prompt and professional service was highly appreciated. In the future we will highly recommend Diamond to our clients.”
