Civil Engineering Measurement Units
Same type of work under different condition and nature shall be measured separately under separate item e.g.
• Work under water
• Work in liquid mud
• Work under tides
• Work in snow, etc.
In case of structural concrete, brickwork or stone masonry, the work under following categories shall be measured separately and the height shall be described.
• From foundation to 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.
