- Summary:
- New noncontact technologies have been developed and implemented for determining as-built condition and current dimensions for a wide variety of objects and buildings. In this study, a three-dimensional laser scanner was used to determine the dimensions and visual condition of a historic bridge in the Amnicon Falls State Park in northern Wisconsin. 3D scanning provides millions of data points of information about the bridge being inspected. The point clouds of data collected depict all visible aspects and actual dimensions of the bridge. This information can be used to determine areas of the bridge that show excessive deflection, rotation or skew of the structure, damaged members, and other visual indicators that a human eye cannot easily identify or quantify. This technique could be incorporated into a comprehensive inspection protocol for historic covered bridges that includes 3D laser scanning, visual inspection, hammer sounding and probing, moisture content determination, stress-wave timing, and resistance microdrilling.
