Mobile District contracted SEAS to perform a high accuracy survey to obtain high-resolution data on the entire dam structure at Carters Re-Regulation Dam in Murray County, GA. This included above and below the water surface and the roadway bridge across the structure. The SOW required deliverable in AutoCAD Civil 3D (2020) drawing format at a scale of 1”=30’ and a 3-D Model and point cloud of the structure for analysis. SEAS collected High-Accuracy LiDAR and Multibeam Hydrographic survey data.

SEAS was contracted by the USACE Little Rock District (Under SEAS Fort Worth Contract) to perform hydrographic multibeam surveys, high-resolution side scan sonar, volume computations, and 3-D digital mapping for scour detection at 4 dams in the Little Rock District: Millwood Lake, Dierks, DeQueen, and Gillham Lakes (Tri-Lakes)
