The Bureau of Reclamation required detailed planimetric and topographic data of the foundation abutments of the dam with topography at a 2' contour interval.

Tasks performed by DJ&A:

  • Horizontal and Vertical control surveys using GPS and differential leveling
  • Tied existing local control marks
  • Established new control marks
  • High Definition Laser Scanner Survey over the entire dam (+/- 900' dam crest) facility and adjacent right and left abutment upland areas (+/- 10 acres)
  • Processed over 30 million laser scanner points (northing, easting, elevation)
  • Generated 100 scale and 60 scale planimetric and site mapping with two topographic contour mapping
  • Produced 3D structure modeling and facility animations
