Soil volumes are measured as:
Clearly differentiate between:
Attention !!!! - Important Point
Swell
Measure densities using laboratory tests
Why does soil or rock swell when dug?
Constant quantity has different volumes
Our constant mass (say 1.63 tonne)
We defined quantity by mass - why?
Payment for earthworks
But how to handle progress pays?
Progress payment based on bank measure
Summary re payment
