Before contacting your Scan2Core GPR technician

All GPR scans begin and end with the initial underlying need a given contractor or client may encounter.  Each project usually begins with a phone call.  It is important for you to have as much information as possible before making that call.  We will need to know several pieces of information regarding your project:

  • The number of cores or areas that you will need scanned
  • The material makeup of the concrete deck or surface your needing imaged
  • Any contractual agreements necessary
  • Any congestion or items on the surface that might interfere with imaging and mapping process
  • What writing utensil should be used when marking findings on surface– permanent, crayon, chalk, pencil, paint stick, etc…
  • Job name, PO# or Job#
  • Site address
  • Site contact
  • Time and date for scanning to be performed
  • Email for sending final invoice, photos, findings, reports
  • Site contact must be present to complete communication cycle job site requirements implemented by Scan2Core, Inc.

From there, our GPR imager will arrive at the job site at the pre-determined time to meet the site contact and go over the specific locations you need scanned.  Depending upon the amount of areas you need imaged and the overall scope of work, our tech will finish the work on time and on budget.  Our GPR tech will report all findings to the site contact and will take photos of all work completed which will then be attached to a final invoice with a report of our findings included.  It is the responsibility of our technicians to clearly communicate with the site contact any dangers or issues that he/she may have encountered with specific locations scanned.  If a complete cycle of communication was not met, our GPR technician will not give a green light to cut, core, drill, or embed until our job site communication requirements have been fully implemented.

When should you have your project scanned?

If you have been in the commercial construction industry for any length of time, then you are well aware that the use of ground penetrating radar (GPR) is just now beginning to play an integral role. In the days of old, if you needed to cut, core, drill, or embed, you simply lined up the saw or the drill and did your thing. If you cut an important item, well, that was just the cost of doing business. “Move on….nothing to see here” was a common phrase.

Today, however, is very different. For starters, there is so much building infrastructure that is being placed within a given concrete deck that is vital to the building’s day to day operation: Elevator conduit; general electrical conduit and smurf; pex hot and cold piping; pt cables; and other building critical items. All of these items need to be missed when core drilling or cutting concrete. And, as retailers come and go, tenant improvements (TI’s) are without end, most of which require cutting, embedding, and core drilling.

There is always a learning curve as laborers in the field of commercial construction attempt to keep up with the needs and processes used by architects, engineers, and building owners today. Monitoring what is taking place on a tenant upgrade in a given building is critical to the success of the project, and to the structure of the building itself. I am continually surprised at the disconnect in the field of day to day operations and job safety. Many laborer’s will still cut, core drill, and embed, without even a thought of hitting these critical items. On one job I was recently on, the electricians were anchoring an item to the lid without having the area scanned first. They would just pick a spot and drill there 3/4″ hole as deep as they needed. The problem with this ongoing philosophy is multifaceted. PT cables, conduits, and other items can often be within 1/2″ of the top or bottom of the deck. The second your tool penetrates the concrete deck without scanning, is the second you are leaving safety to chance!

It is my hope that as building inspectors, owners, and general contractors get up to speed and continue to improve safety and performance on the job, we will soon see ground penetrating radar technicians on every project.

So, in answer to our question “When should you have your project scanned?”, any time the existing concrete deck will need to be penetrated, you need to have your project scanned. Your safety depends upon it!

The art of choosing the right GPR Antenna

Differing concrete decks require a GPR technician to be fully aware of changing situations. For instance, if you have a concrete deck that is 20″ thick, a 2.6 mhz antenna is not going to penetrate the concrete much beyond 10″ and will give you an incomplete reading of all items that are below the surface of the concrete. A properly trained technician from Scan2Core, Inc.. will recognize this immediately and will change antennas from a 2.6 mhz to a 1.6 or 1.5 mhz antenna and will adjust many of his/her other settings in the GPR unit as well, which will enable better visibility. One of the most important items to identify when scanning concrete is to clearly identify the bottom. Failure to accomplish this initial task can lead to wrong interpretations of items in or below the concrete slab.

After 2,000 years, a long-lost secret behind the creation of one of the world’s most durable man-made creations ever—Roman concrete—has finally been discovered by an international team of scientists, and it may have a significant impact on how we build cities of the future.

Before you begin your next project and start drilling, cutting, coring, or sawing into concrete, it’s important to make sure that there is nothing embedded or hidden that could cause harm to workers or damage the infrastructure causing costly repairs.

Since taking a risk without a GPR scan or X-Ray is not an option, how do you decide which one to use? Let’s break down the advantages and disadvantages of each.

Intro to Concrete Scanning with Scan2Core, Inc.

Nondestructive GPR Testing Concrete Scanning Services

Concrete Scanning is used to image conduit, pipe, rebar, post tension cables, voids, mesh, concrete thickness. Like an X-Ray .

Scan2Core, Inc. is a structural imaging and core drilling company using the latest and most advanced mobile, Ground Penetrating Radar (GPR) concrete scanning technology. Unlike X-Ray equipment which requires job site evacuation and access to both sides of a concrete structure, GPR is a non destructive concrete inspection system that can locate rebar, post tension cables, pipes, and conduit in concrete structures, slabs, floors, and walls. This technology is much safer than X-Rays and can be performed without disturbing areas or occupants of structures.
