AutoCad Process of CUT/FILL

AutoCAD Process of CUT/FILL

Step-by-step process of how I calculated the CUT/FILL volumes for Canon Park for the Sustainable Technology module AD6604 

  • existing contours = dashed line 
  • proposed contours = solid line
  • pond = blue 
  • red = CUT
  • green = FILL


1. DRAW EXISTING CONTOUR LINES



2. LOCATE NEW POND



3. DRAW NEW CONTOUR LINES & JOIN TO EXISTING



4. ISOLATE EACH CONTOUR AND HATCH FILL/CUT 

(BELOW = FILL = GREEN) 

(ABOVE = CUT = RED)




5. ADD UP TOTAL AREAS X HEIGHT CHANGE (0.5m for contours & 0.25m for pond/swales)

CUT:

RED CONTOURS = 4074.73  x  0.5 = 2037.3650 
SWALES = 456.81 x 0.25 = 114.2025 m³ 
POND = 1826.64 x 0.2 = 456.6600 m³ 

TOTAL CUT VOLUME = 2608.2275 m³ 




FILL:

GREEN = 3435.34 x 0.5 = 1717.67 

TOTAL FILL VOLUME = 1717.67 

DIFFERENCE = 890.5575 

As there is a substantial difference, consider increasing mound size...
