This is my 4th video on estimation or Quantity Survey and in this video, I explain in detail how to calculate the volume of Excavation of the foundation of a single room. For an explanation of the centerline method, I use one plan drawing, Cross Section Drawing & Foundation Plan. 1st I calculate the total length of all walls from the center then use foundation Cross Section and apply this cross Section for Excavation quantity, Concrete Quantity, For DPC Quantity and For Brickwork Quantities
