Drone at Work

Simple map of a subdivision to verify subgrade for the road before laying curb and top of pad elevations for the lots. The point cloud was loaded into Carlson Precision 3D Topo and a DTM was made that imported into Carlson Civil to compare against the proposed model. Trick was manipulating the proposed model to represent top of pad and road subgrade instead of finish grade. We found a 1,200cy bust in the materials quantities that was an unknown export. It is now being transferred to a different project that needs import. All analysis was done in CAD for accuracy and alignment purposes.
