Civil Construction

Tenders and setout

• Replicate designs for tenders or setout
• Compute quantities for tenders
• Transfer designs from paper or add to insufficient digital data
• Setout Designs
  • Set-out radiations of any points
  • Chainage and offset from a straight line
  • Chainage and offset from a curvilinear alignment
• Compare coordinates of design features with as-constructed features
• Position monitoring

Volumes

• Net Prismoidal Volumes between DTM surfaces
  • Compute between two surfaces or between one surface and a datum.
  • Apply arbitrary boundaries.
  • Concrete pours
  • Open-cut mines
  • Stockpiles
• Cut and fill volumes from Cross Sections
  • Use centreline or centroidal distances between sections.
  • Clip cross sections at a horizontal plane in obtain the volume either above or below the plane. The process can be repeated to obtain the volume between two horizontal planes.
• From contours
  • tabulated for each contour.
  • Volumes of dams and dam walls
• In grid cells
  • Calculate cut, fill and net in each grid cell.
  • Report totals in larger grid cells.
  • Use where an area has multiple cut/fill transitions or where earth movement is not simply linear.
  • Great for golf courses.
• Slope conditions
  • Display and plot triangles with % grade or hatch according to grade.
  • Compute horizontal and surface areas within slope ranges
