Earthwork shall be taken in cu.m. and the length, breadth and height or depth shall be measured to get the cubic content.

Earthwork of different nature as in excavation in foundation, in trenches, etc., and in filling in plinth, in banking, etc., shall be measured under separate items.

Earthwork in different kinds of soil as ordinary soil, hard soil, ordinary rock, hard rock, etc., shall be classified separately and measured under separate item.

Dressing or trimming and leveling or grading, ramming and consolidation thickness of each layer, etc., shall be described and included in the item of earthwork.

Measurement of excavation or trenches or borrow pits shall be taken for average dimensions.

When the ground is fairly uniform ‘Deadman” or “Tell-Tales” which shall be left at suitable intervals to determine the average depth of excavation.

For uneven or sloping ground, diagonal ‘Tell-Tales’ shall be left.

No deduction shall be made for Deadman, Tell-Tales which shall be removed after the measurements have been taken and checking has been completed.

Answer 2

Answer:

4.5 m

Explanation:

Shallow excavations are defined as being anything less than 1.5 meters deep, which really is not very deep at all; a relatively short person could comfortably see over the top. Deep excavations, on the other hand, are defined as being any excavation that is more than 4.5 meters in depth – a considerable height indeed
