Unit of Measurement in Civil Engineering

The same type of work under different condition and nature shall be measured separately under separate item e.g.
• Work underwater
• Work in liquid mud
• Work under tides
• Work in snow, etc.

In the case of structural concrete, brickwork, or stone masonry, the work under the following categories shall be measured separately and the height shall be described.
• From foundation to the plinth
• From plinth level to first-floor level
• From first-floor level to second-floor level and so on,

The bill of quantities shall fully describe the material, proportion, and workmanship and accurately represent the work to be executed.
