12. Unless otherwise specified weights shall be measured to the nearest 0.001 kg.
13. Steel reinforcement in RCC work shall be measured separately in another item.
14. To achieve desired accuracy in measurement length of reinforcement bar is measured nearest to 0.001 kg
15. To achieve the desired accuracy in measurement thickness of the slab is measured nearest to 1 mm.
16. Unless otherwise specified cubical contents shall be measured to the nearest 0.01 cu. m.

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.
