Concrete Scanning and Laser Scanning for Parking Garage Renovation

The client needed to know the location of rebar, post-tension cables, and electrical conduit in and under the concrete to prevent costly and dangerous mistakes during renovations, repairs, or drilling.

• GPR scanners send radio waves into concrete and detect how they interact with objects below the surface. This creates a readout with different shapes based on the material found.
• GPRS’ SIM-certified Project Managers interpret this data to locate and mark concrete embedment’s and estimate their depth.
• A 3D laser scanner uses LIDAR technology to permanently record a high-resolution 3D representation of the concrete markings in a point cloud.
• The captured point cloud is processed in software like Leica Cyclone or Autodesk Recap, where markings can be identified, extracted, and used to generate 2D drawings or 3D models.

• Ground penetrating radar and 3D laser scan technology minimized risk and helped to ensure a safe, efficient project.
• A 3D BIM model provided the client a permanent record of rebar, post-tension cables, and electrical conduits to avoid cutting post-tension cables, damaging electrical conduits, and maintaining the integrity of the parking garage.
• A 3D CAD model allowed the client, engineers, and architects the ability to overlay data into their own software to assist with both the planning and implementation phases of this renovation project.
