AT WORK | 2019 | Dam 3-A Scanning Project

Hubbard Valley Dam Laser Scanning Project

In 2019, we completed our first laser scan and 3D basemap of a Principal Spillway structure. At Hubbard Valley Dam, (Dam 3-A), the spillway consists of a 25 foot tall concrete riser, 42-inch diameter by 236 foot long outlet pipe and impact basin. GPD Group – Akron was the contractor. The initial report and drawings provide a very detailed basemap of the spillway. Comparisons of the initial basemap and subsequent scans, will indicate any possible compromises of the structure or the pipe. This level of detail will supplement more basic visual inspections.
