GPRS Scans For Conduits At Football Stadium

Ground Penetrating Radar Systems was contacted by a general contractor to locate the conduits inside a suspended slab at the Cowboys football stadium in Dallas, Texas. The contractor needed multiple core drills and anchor locations cleared for the ventilation and piping for the new restaurant opening in the stadium. Concerned about hitting a conduit and shutting down sections of the stadium, or the entire stadium itself, the contractor called upon GPRS to locate all the electrical inside the slab before making any penetrations.

GPRSscreen-13.32.36[16.09.2019].png

We recently received the opportunity to work for a customer who historically has relied primarily on classic X-ray technology rather than ground penetrating radar (“GPR”). They split their project between X-ray and GPR scan areas. By the time we finished the project, the PM contact encouraged us by telling us that they were very impressed with our results and that we would receive a lot more business from them in the future.

Here, I think are some of the reasons why:

Scheduling Flexibility: GPRS can generally mobilize to a site within 3 business days, and we can work day or night, with very little impact to the work around us. Classic X-ray produces harmful radiation that generally requires the work to be done at night with the building cleared. Because GPR uses much lower frequencies, it is as safe as a cell phone and does not require the space to be cleared.

Cost: Our total quote for this entire project was less than 20% that of our classic X- ray competitor. Because X-ray requires a film to be set up for each scan area, it is time and material intensive and thus more expensive.

Safety: When we first arrived on this project, we were informed that a conduit had just been hit when a pilot hole was drilled. X-ray technology requires that pilot holes be drilled blind, and that can result in the very damages that the technology seeks to avoid. GPR operates with zero destructive effect on the slab, and can be utilized from just one side of the slab.

Ground Penetrating Radar Systems was contacted by a construction contractor in Dallas, Texas to locate underground utilities prior to client directional boring new electric lines for site lighting. Ground Penetrating Radar Systems of Dallas, Texas was able to identify and locate numerous underground utilities including fire waterlines, communication lines, electric lines, sanitary sewer lines, gas lines, and unknown lines in the ground and mark them on the surface in order for the client to proceed with their

work safely. While on site, GPRS was also able to take on the role of consultant through expert communication with several different contractors and subcontractors working directly on the project and working in the vicinity of the concerned areas. GPRS was also able to work safely in a heavily trafficked street through constant communication and abiding by OSHA safety regulations. These utility locates allowed the client to proceed safely with their project.

dallas-fort-worth-hospital-scan.png

We recently scanned a large portion of a hospital in the DFW area. The scan encompassed about 15 acres and the customer requested that GPRS mark out the locations of all utilities on site as shown above. When we approach a large project like this, we use a tested GPR methodology to ensure that the scan is comprehensive. SIM (Subsurface Investigation Methodology) includes the following steps: To begin, we search the site for visible signs of utilities, and then we open up utility features (as needed) and use the EM Locator to induce a tone onto anything conductive. By inducing a tone onto each utility, we can follow it and mark it on the surface, and we can get some idea of the depth of the line. Additionally, we know what utility is being toned, so we can generally identify the utility correctly, though this is not always the case. Sometimes, the tone can jump from one utility to another, creating confusion. It is always best to pothole our findings to verify whether all lines are identified correctly.

At this hospital, there was a large sign at the front corner that contained an electrical panel which fed some exterior outlets and site lighting. Unfortunately, this system used the same ground wiring as the irrigation control system nearby, so that when we toned the irrigation, the site lighting showed up, and vice versa. It was very difficult to distinguish between the two, but our experienced technicians were able to tell the difference. By the time we had completed this located, we had a high degree of confidence in our identification of all but two utilities, which were marked with pink, to indicate our uncertainty.

utility-locating-houston-texas.png

Ground Penetrating Radar Systems was contacted by a special services contractor in the Houston Metro area to conduct a private utility scan in an area of concern at a local ExxonMobil facility. The contractor needed to excavate around some existing water valves for some underground maintenance on the water lines coming from these valves. Part of the facilities ground disturbance regulations was to call in a private utility locate to minimize any damage or dangers during this operation. Enter GPRS, the largest provider of private subsurface locating in the country. Within 24 hours, the Houston branch of GPRS mobilized to the site to conduct the locate. When GPRS arrived on site, the site contact for the contractor walked us to the area of concern and pointed out all the potential issues. Right away, we were able to determine that the area was going to be highly congested with pipelines, water lines and electric conduits based on just basic observation of aboveground indicators. GPRS conducted the scan using a 350Mhz GPR antenna and RD8100 electromagnetic pipe locator. GPRS was able to mark these out and save on potentially thousands of dollars in damage and prevent any possible injuries. Using the SIM (Subsurface Investigation Methodology) system that was created by GPRS, the contractor was provided with clear markings and a walk-through of all findings. The contractor was able to make all necessary adjustments to the drilling in real time as the GPRS Project Managers completed each of the scan areas. During this process, the GPRS Project Manager on site provided clear and concise communication with the client on all site limitations and findings. Using the information provided, the client was able to make informed decisions, keeping their project on time, under budget, and most importantly, safe. Safety is top priority with GPRS; all necessary personal protective equipment (“PPE”) is utilized at all time on all work on sites, and our goal is to get our team, and yours, home safely.

texas-utility-locating-1.png

We were recently asked to locate utilities in an area that had previously been located. The customer was aware of a few utilities, and plans showed their basic layout, but their exact locations and depths were needed. Based upon the customers understanding that not many utilities were to be found within the scan area, we scheduled the work for two hours of scanning.

Previously undetected utilities located as we began to scan, we started by locating all of the known utilities, which had previously been found, but whose markings faded beyond recognition. But we did not stop there, we continued locating and found at least 4 utilities that the previous locator had missed. Finding these utilities required more time than we had planned for the job, but we honored our original price and delivered a better locate than the customer was expecting. He asked for a business card and inquired about how he could send along positive feedback.

Experience Matters How is it possible that some locators can find utilities that others cannot? First, it must be said that not all utilities can be located. Full stop. Some utilities simply lie beyond the reach of the current technology. Other utilities are easy to find, and indeed may be very hard to miss. Between those two extremes there lies a grey area--utilities which are at the edges of what the current technology can locate. Those utilities are the reason that not all GPR companies are equal, and why it is

hospital-floor-scan-in-plano-texas.png

Hospital jobs tend to be relatively difficult and high-stakes. Hospitals are large buildings, and they are often irregularly shaped, which means they have unusual configurations of reinforcing steel in their slabs. This makes concrete scanning more challenging than in a typical rectangular structure. Additionally, hospitals have critical utilities that can literally make the difference between life and death.

On a recent job in Plano, Texas, we scanned the floor of a hospital structure in order to map out all critical utilities and reinforcing steel, including beams. In most buildings, you can guess where the beams are simply by looking (or shining a laser) up, because beams usually run in a set pattern all the way up a structure. That was not the case on this job. Only one of the main diagonal beams was consistent between our floor and the floor overhead. The rest of the beams ran in alternate pattern, which we marked out with blue paint (see photo). Additionally, there were large pieces of rebar running diagonally across the main beams and into the slab, and there were smaller pieces of steel running in a tight grid throughout the whole scan area. We communicated the latter fact to the customer, and we were told those lines did not need to be marked, as they were consistent.

CLIENT PROBLEM

Client was in the process of installing bollards in a parking garage on the University of Texas campus. The bollards required to be bolted into the concrete with a penetration of three inches with a total of twenty-four penetrations. GPRS of Austin, Texas was contacted by a contractor to locate reinforcement within the concrete slab at the proposed site of the bollards. The client was looking to drill into the concrete slab to install the bollards without striking any reinforcement in the process.

HOW WE RESPONDED

GPRS arrived on site the next day with the latest equipment from one of the top industry leaders used for digital concrete imaging utilizing ground penetrating radar to map out the contents of the slab to determine how to proceed with their project safely.

RESULTS WE DELIVERED

GPRS provided illustrations marked directly on site in real time, to provide an accurate mapping of the reinforcement within the slab. This provided just what the contractor needed, so that they were able to safely anchor the bollards to the slab without compromising any structural integrity or personal safety of workers. GPRS utilizes multiple pieces of equipment that play a key role in the discovery of all reinforcement and conduits that lay beneath. The client was able to avoid all reinforcement as well as an unknown electrical conduit.

post-tension-cables-located.png

Prior to drilling and installing over 100 anchor and concrete core locations for new plumbing, electrical and HVAC systems, a local general contractor subcontracted Ground Penetrating Radar Systems, LLC to scan and locate post tensioned cables throughout the entire store. The contractor knew that the concrete slab on the floor and ceiling contained post tensioned cables and wanted to avoid them for the duration of all drilling. This was the contractor’s first time working with GPRS and after asking around other general contractors, many other companies referred GPRS as their go-to concrete scanning company. Since the anchor locations were on the ceiling, GPRS also rented and provided an aerial lift with certified Project Manager’s for the duration of the project. After mobilizing to the jobsite, the Ground Penetrating Radar Systems team was able to locate multiple post tensioned cables and conduits running in the floor and ceiling slabs. Many of the areas where the contractor wanted to drill floor cores had conduits running directly through the area. GPRS was able to mark these out and save on potentially thousands of dollars in damage and prevent any possible injuries. The GPRS team was also able to locate multiple post tensioned cables directly in the areas of concern in the ceiling anchor locations and floor core locations. Using the SIM (Subsurface Investigation Methodology) system that was created by GPRS, the contractor was provided with clear markings and understanding of all findings.

learn-gpr.jpg

We often get asked whether we went to school to learn GPR/ utility locating. Our technology and industry remain somewhat novel to most casual observers, who want to know what it takes to become an expert in GPR. The answer to the school question is both ‘yes’ and ‘no’.

No, the utility locating industry is not large enough to warrant degree programs. But, yes, GPRS has a world-class training program, fit with dedicated instructors, a well-developed classroom curriculum, and even a ‘practice’ field of deliberately positioned buried utilities for the new trainees to test their skills on. We also have an advanced course for continuing education and many hours of online videos and interactive content. All new team members go through a months-long ride along, and we have rigorous quality control protocols and SOP’s. We have an external certification (www.simspec.org) that governs both our initial and ongoing training standards.

But there is another, even greater sense in which most of us can say, “Yes, I went to school for this”. That is, we regularly scan America’s school and universities, and those jobs are some of the most challenging and rewarding jobs we do. In our experience, schools have more utilities per acre than almost all other non-industrial facilities (second only, perhaps, to theme parks). Schools, especially larger universities, are often constructed in phases, through an iterative process, as they grow and expand. Utilities are layered on top of one another, sometimes abandoned in place, sometimes redirected at odd angles.

abandoned-underground-pipelines.png

Prior to excavating and trenching for over 100 wind turbine foundations, 17 miles of access roads and 51 miles of collection lines, a major wind energy contractor subcontracted Ground Penetrating Radar Systems, LLC to locate active and abandoned underground utilities throughout the entire project area. The contractor knew of multiple oil and gas pipelines running throughout the project and needed GPRS to confirm the known utilities and identify any unknown or abandoned utilities. After working with GPRS on dozens of other projects, they knew exactly who to call to meet their needs on this project. After mobilizing to the jobsite, the Ground Penetrating Radar Systems’ team was able to locate and confirm multiple pipelines within the excavation areas on just the first day on site. While scanning one of the wind turbine foundation areas, GPRS marked an unknown buried utility that ran directly through the excavation area. This utility was not marked on any historical map nor was it known by the contractor ahead of time. Using Electromagnetic Line Locating and GPR technologies, they were also able to trace out the utility throughout the entire area of concern. Upon reaching the end of the project boundary, the utility was exposed above ground and turned out to be an abandoned gas pipeline. The contractor was able to visually see all of the findings due to the easy to interpret flagging and staking system used by GPRS to mark all their findings. After the area was scanned, the gas pipeline location was collected via GPS and exported to a daily Google Earth KMZ file for the client to use in the future, holding a convenient and precise permanent record. A post scan walkthrough was also conducted with the GPRS team and the client to explain all our findings and answer any questions the client may have. After reviewing the results, the client was grateful that GPRS was able to identify the previously unknown utility. The contractor went back to the drawing board and made an alternate wind turbine foundation location based on the findings, avoiding the buried pipeline entirely. During this process, the GPRS Project Manager on site provided clear and concise communication with the client on all site limitations and findings. Using the information provided, the client was able to make informed decisions, keeping their project on time, under budget, and most importantly, safe. Safety is top priority with GPRS; all necessary personal protective equipment (“PPE”) is utilized at all time on all work on sites, and our goal is to get our team, and yours, home safely.

The Henry B Gonzales convention center in San Antonio is undergoing multiple facility renovations. The contractor’s main concern was to protect the existing infrastructure during excavation. French drains are perforated PVC pipes the typically installed on top of the clay layer of soil underground to insure the proper movement of groundwater, thus preventing standing water and over watering to occur. Trough drains are a linear floor drain typically used in preventing standing water on smooth surfaces where water is prevalent. The contractors were told to be cautious when digging due to all the utilities in the trenching areas.

GPRS was able to respond within 24 hours to identify private underground utilities in the area of construction. We utilized our time on site efficiently by ensuring the client’s needs were met and exceeded by first taking time with the facility managers, engineers and contractors to understanding the specific areas where the drains were to be installed. Gaining access to the known utility structures in the surrounding areas as well as viewing accessible as-built drawings to ensure all known utility structures were identified. We took notice of obstructions and possible complications on site and brought them to the client’s attention.

Ground Penetrating Radar Services

Prior to excavating and trenching for new electrical and communication conduit install, a local electrical contractor subcontracted Ground Penetrating Radar Systems, LLC to locate possible utility lines in select areas throughout the property. The contractor noticed multiple electrical conduits running into the ground near the area they were about to dig and needed to safely clear the area of underground utilities. After a quick internet search for Houston area utility locators, the contractor got in touch with GPRS. After mobilizing to the jobsite, the Ground Penetrating Radar Systems team, was able to locate the electrical conduits that the contractor noticed. During the site walkthrough, GPRS also noticed evidence of multiple other utilities in the area.

Using Electromagnetic Line Locating and GPR technologies, they were also able to detect a handful of other underground utilities, including communication lines and water lines. The contractor was able to visually see all of the findings due to the easy to interpret color coding and flagging system used by GPRS to mark all their findings. After each area was scanned, the utility line locations were collected via GPS and exported to a Google Earth KMZ for the client to use in the future, holding a convenient and precise permanent record. A post scan walkthrough was also conducted with the GPRS team and the client to explain all our findings and answer any questions the client may have. After reviewing the results, the client was grateful that GPRS was able to mobilize in such a short notice to safely clear the jobsite. Using the information provided, the client was able to make informed decisions, keeping their project on time, under budget, and most importantly, safe. Safety is top priority with GPRS; all necessary personal protective equipment (“PPE”) is utilized at all time on all work on sites, and our goal is to get our team, and yours, home safely.

GPRS recently did three jobs at the DFW International Airport. These jobs were back to back to back for different contractors. Ground Penetrating Radar Systems scanned for utilities around an underground storage tank (UST), as well as for the tank piping, then later scanned a concrete foundation to mark out footers and steel, and finally scanning for utilities in the large open area pictured above where peers will be driven 30 feet into the ground. It was an extremely cold day, and it is difficult to see in the picture but there was ice frozen to the ground. GPRS has performed in most scenarios around the United States after completing hundreds of thousands of jobs since its inception in 2001. We are ready to handle whatever difficulties your job may include.

UST Search – For the job involving the UST, the tank itself was buried too deep to see with the GPR, but there was a small underground tunnel where pipes from the tank had previously run into the airplane hanger. We were able to run a traceable rodder down that tunnel and it navigated right to the UST. We induced a tone onto the rodder line and we were able to capture the piping from the tank, and the location of the tank itself.

The client was contracted to install bollards in a parking garage on the campus of The University of Texas at Austin. Twenty-four bollards were to be installed and secured to the concrete with three-inch long concrete anchors. GPRS of Austin, Texas was hired by the client to scan and locate reinforcement within the concrete slab in the proposed bollard locations. The purpose of the scan was to identify and mark the existing post tensioned cables so they could be avoided when drilling for installation of the anchors.

GPRS arrived on site within 24 hours of the client’s request. Using the latest equipment from one of the industry leaders, GPRS employed ground penetrating radar to map out the contents of the slab and provide the client with precise locations of the critical embedments so the client could safely install the bollards without incident.

GPRS provided exacting marks, representing the embedded steel reinforcement, directly on the concrete surface in real time, giving the client precisely what they needed. The client was then able to safely anchor the bollards to the slab without compromising any structural integrity or personal safety of the workers on site. GPRS utilizes multiple pieces of equipment that play key roles in the discovery of all reinforcement and conduits for your subsurface projects. The client was able to avoid all reinforcement as well as an unknown electrical conduit that was detected during the initial scan.

Ground Penetrating Radar Systems was contacted by a general contractor to locate the post tension cables and conduit running through a residential slab of concrete. The general contractor was concerned of the safety issues with his contractors hitting an electrical cable or a high tension cable. GPRS was able to come on site within 24 hrs of the requested job and safely locate all of the post tension and conduit running inside the slab of concrete. There is an extreme amount of pressure on post tension cables and if one is struck or cut, this could create an extreme safety issue for the other contractors on site and create a serious structural risk to the building. Conduits are another important object to locate while saw cutting or core drilling. The electrical safety hazard to the contractor striking the line would be at extreme risk of electrocution. This can also pose to be a costly mistake to fix for the general contractor on site.

Ground Penetrating Radar Systems, LLC. was contacted by a contractor that needed to know the location of utilities prior to trenching earlier this month. The client's primary concern was to determine the location of any utilities or other near-surface items within the excavation area prior to digging so that they can place directional signs. The project consisted of clearing approximately 1000’ of trench line. Utilizing the latest in GPR and Radio Detection technology, Joseph R. Granados of the EL Paso, TX Office scanned the site and was able to mark out several utilities traveling through the proposed areas. All of the utilities that were located were then marked directly onto the service in real time while GPRS was on site. The use of ground penetrating radar allowed the client to stay safe while digging and helped to keep them on their tight completion schedule. With the professional services provided by GPRS, no utilities were struck during the excavation of the three areas allowing the client to stay safe on this project.

The client was extremely concerned of hitting heavy electrical due to the active hospital surrounding the job site that could be shut down if a significant line was struck. The electricians met Ground Penetrating Radar on site and walked through the project details while marking out locations that needed to be cleared of any and all utilities.

GPRS was able to come out and successfully locate exactly where all of the utility lines were located making this a quick and easy trench line to locate. This also helped the customer to

Locating-Embedded-Conduits-and-Buried-Utilities-Dallas-TX.jpg

When saw cutting or coring, utilities like electric, water, and gas lines are embedded and/or buried to keep them safe from damage that could occur on the surface by people, equipment, weather, etc. It is extremely important that when saw cutting or coring near these buried utilities, that one takes great care in ensuring these utilities remain safe from damage. This is why contractors in North Texas tasked GPRS with tracing electrical lines and scanning concrete prior to excavating an area nearby. Using specialized tools, the lines in question were safely located so work could proceed without incident.

With this problem hundreds of gallons of water were wasted and the ground will have to be repaired prior to work continuing.
