Concrete Scanning With GPR - Documentation in the 21st Century
BEAM
Documentation on a job site is critical and just as important as generating the results by scanning the structural supports. When the scanning part is finished and the reinforcement layout is completed, the next step is to capture the result in the most efficient way. OmniVueNDT has integrated LiDAR scanner in their site documentation work process to capture a scaled and measurable 3D model of every scanned object, surfaces to recreate the virtual reality model of the job site.
That type of documentation would allow us to make the job site (the scanned area) portable and be able to share every detail with the client or the engineering group for future reference or designing purposes. Accurate measurement can be taken of the reinforcement layout such as rebar, post tension cable spacing and reference to a permanent structure like a column, drain grate, etc.
The following images indicate an example of proper site documentation in the OmniVueNDT way. A section of the beam was scanned with HDF GPR to locate the profile of PT (Post Tension) cables inside the concrete beam. It is noticeable that the PT cables are exiting the beam and at one section they are running inside the concrete slab. That happens where the column is located so the cables are creating pressure, force onto the column by pushing it downwards.
