  • 5 Minute Read

Content

Following a combined drone LiDAR and bathymetric survey, Matrix has undertaken a cut and fill analysis for urgent repair work on the River Lewes, in Brighton.

  • Exact cut and fill quantities
  • Cost certainty before the works begin
  • The effect of the works on river flow, calculated rather than assumed
