The site is required to be reduced to a level of Zero. Calculate the total volume of excavation? 

Assume the cost of excavation (direct cost) is 15 SR per 1 m3 (this cost only includes the equipment and labor prices)

  • VAT 15%
  • Overheads 10%
  • Contingency 6%
  • Profit 12.5%

Note: each square is with total area of 6*6. And the level of excavation for each square to reach to level Zero as illustrated below.
