LABOUR REQUIREMENT FOR VARIOUS CONSTRUCTION WORKS

LABOUR REQUIREMENT FOR VARIOUS CONSTRUCTION WORKS: The cost of construction project highly depends on the requirements of labour for various activities during construction. There are direct and indirect costs associated with the labour. They are the salary of labours, their accommodation, food, insurance cost etc. Thus it is essential...

CALCULATE QUANTITIES OF MATERIALS FOR CONCRETE

Quantities of materials for the production of required quantity of concrete of given mix proportions can be calculated by absolute volume method. This method is based on the principle that the volume of fully compacted concrete is equal to the absolute volume of all the materials of concrete, i.e....

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...

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 followingOpening up to 0.1 m2 Volume occupied by reinforcement. Volume occupied by...


METHODS & UNITS OF MEASUREMENTS OF CIVIL WORKS

The units of measurements for civil engineering works are mainly categorised for their nature, shape and size and for making payments to the contractor. 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...

SIZE AND QUANTITY OF REINFORCEMENT FOR BUILDING WORKS

Reinforcement is required for reinforced concrete members such as footings, beams, columns, slabs, lintels etc. Estimation of reinforcement quantity is required prior to tendering stage to calculate approximate cost of project or construction work.Following table gives the estimated quantities of reinforcement and its size generally used for various building...

ESTIMATION METHODS OF BUILDING WORKS

The estimation of building quantities like earth work, foundation concrete, brickwork in plinth and super structure etc., can be workout by any of following two methods:a) Long wall - short wall methodb) Centre line method.c) Partly centre line and short wall method.a) Long wall-short wall method: In this method, the...
