• In a construction industry it is important to
  identify metal targets and underground utilities
  before cutting into concrete, so as to avoid any
  damages or mishaps. Despite proper
  identification, there are stories about mishaps
  because the rebar, post-tension cables, and
  conduits in concrete structures were not
  accurately marked before drilling, cutting,
  coring, trenching, or digging. Therefore, it is
  highly important to use a reliable and authentic
  scanning method. This article discusses the
  importance of digital concrete rebar scanning,
  and the consequences of inaccurate marking.

Importance of Digital Concrete Rebar Scanning

• During digging or excavation if an underground
  utility gets damaged, it can lead to serious
  consequences. The damages can range from project
  delays to cost overruns, and even worker hazards.
  Not only this, the damaged facility might cause
  grave environmental hazards as well. At times
  cutting rebar can be the supportive beam upon
  which the whole structure is constructed. Any
  damage to rebar may cause damage the building to
  the extent that the structure might even
  collapse. Likewise, cutting electrical conduit
  can put the whole project on pause, and cause
  serious injuries.

Follow Best Practices

• Every scanning procedure has its fair share of
  shortcomings. However, GPR scanning helps
  contractors identify potential hazards, so that
  they can be avoided along with the cost of fixing
  those damages. To protect you from the hassle of
  interrupted services in a building construction,
  it is recommended to follow the best practices.
  These include following

5
Select the Right Equipment

• The equipment for digital concrete rebar scanning
  takes a beating therefore, it must be durable
  and sturdy. It should be easy to operate, and
  user-friendly. GPRs display is intuitive, bright
  and it produces results in high resolution,
  making it easy to analyze the data.

6
Use GPR to Determine Location and Depth of
Hindrances

• Before starting construction or any excavation,
  use GPR to determine what lies underneath that
  surface. Other than identifying the type of
  material, you might want to know the depth at
  which it lies so as to avoid any additional
  costs. With detailed information of subsurface
  utilities, the operator has a clear idea about
  what can be cut, how deeper the excavation can be
  carried out without damaging any lines, and which
  locations should not be disturbed in any way.

Follow Concrete Sawing and Drilling Association
(CSDA) Guidelines

• The American Society for Nondestructive Testing
  (ASNT) and the Concrete Sawing and Drilling
  Association (CSDA) is in the process of making an
  industry-wide training/certification. The
  guidelines and obligatory protocols will be
  included in this so that they should be followed
  when developing a scope of work that requires
  concrete cutting. Instead of waiting for the ASNT
  and CSDA to making it obligatory, you should
  start using the proposed practices right away.
  After all, it is for your own good.

Maintain Good Communication with Imaging
Contractor

• In any construction project, it is advised to
  maintain good communication with the imaging
  contractor to avoid any misinterpretations of
  data. Especially in the absence of standardized
  marking system, it is for the best to keep the
  communication channel open, because it is quite
  possible that one scanners marks may look
  different from anothers. it is also important so
  that all parties have an understanding about the
  projects progress.

How does Digital Concrete Rebar Scanning help?

• Digital concrete rebar scanning uses GPR (Ground
  Penetrating Radar), which helps avoid potential
  problems and damages.

10
X-Ray Technology Just Does Not Cut It Anymore

• In the past, X-ray technology was highly popular
  due to its non-destructive technique used to
  locate and identify subsurface utilities.
  However, majority experts now believe that GPR
  concrete scanning is the most efficient technique
  because it allows project to finish within
  defined timeline, more efficiently, and more
  accurately in real-time.

11
GPR offers more Reliability and Freedom

• Compared to x-ray, GPR does not emit radioactive
  waves which lets the personnel to work safely at
  the construction site along with other trade
  workers. Moreover, GPR equipment is more
  user-friendly and affordable than the X-ray
  technology.

Conclusion

• Digital concrete rebar scanning helps locate
  underground utilities in a non-destructive
  manner. It also helps identify structural
  reinforcement and anomalies. This includes
  identification of voids and conduits. By avoiding
  any mishaps and damages, GPR helps avoid the cost
  of damaged structure and the cost required to
  repair them. To know more about Digital concrete
