Material Estimation

QUANTITIES OF MATERIALS PER CUBIC METRE OF CONCRETE

Quantity of materials such as cement, sand, coarse aggregates and water required per cubic meter of concrete  and mortar varies with the mix design of the concrete and mortar respectively. Following table gives the estimated quantity of materials required per cubic meter of mortar and concrete for various nominal mixes. NOMINAL MIX   WATER CEMENT […]

MEASUREMENT OF REINFORCED CONCRETE WORKS

Measurement of Reinforced Concrete Works: 1. The Quantities can be rounded off to the nearest two decimals. 2. Concrete in Structural members, such as columns, Beams and slabs shall each be measured separately. 3. No Deductions shall be made for the following Opening up to 0.1 m2 Volume occupied by reinforcement. Volume occupied by pipes, […]

METHODS & UNITS OF MEASUREMENTS OF CIVIL WORKS

The units of measurements (UOM) for civil engineering works are mainly categorised for their nature, shape and size and for making payments to the contractor and also. The principle of units of measurements normally consists the following: a) Single units work like doors, windows, trusses etc., are expressed in numbers. b) Works consists linear measurements […]
