Unit Of Measurement In Civil Engineering Works

Unit of Measurement in Civil Engineering Works

Civil engineering involves the planning, designing, and construction of various structures, such as buildings, bridges, roads, and water supply systems. In order to accomplish these tasks, civil engineers use a variety of units of measurement.

Some of the most commonly used units of measurement in civil engineering include meters, feet, inches, millimeters, and centimeters for length, cubic meters, cubic feet, gallons, and liters for volume, and newtons, pounds, and kilograms for force.

These units of measurement are used to specify the dimensions, quantity, and properties of various construction materials and components.

To achieve the desired accuracy in measurement thickness of the slab is measured at nearest to 1 mm.
Unless otherwise specified cubical contents shall be measured to the nearest 0.01 cu. m.

The same type of work under different conditions and nature shall be measured separately under separate items 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 the foundation to the plinth
From the plinth level to the first-floor level
From the first-floor level to the 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.

Basic Units of Measurement

Following are some basic units of measurement,

The seven SI base units are comprised of:

Length – meter (m)
Time – second (s)
Amount of substance – mole (mole)
Electric current – ampere (A)
Temperature – kelvin (K)
Luminous intensity – candela (cd)
Mass – kilogram (kg)
