**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.

â€¢ Work underwater

â€¢ Work in liquid mud

â€¢ Work under tides

â€¢ 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.

â€¢ From foundation to the plinth

â€¢ From plinth level to first-floor level

â€¢ 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.
