Material quantity calculation for Plastering, Concrete and Mortar

• Plastering material quantity is calculated based on the area to be plastered and the thickness of the plaster.

• Concrete material quantity is calculated based on the volume required for the structure, considering the mix ratio and wastage.

• Mortar material quantity is calculated based on the volume required for the masonry work, considering the mix ratio and wastage.

• For example, to calculate the quantity of plasteri...read more

Rolling margin is the difference between the cost of goods sold and the selling price, calculated on a rolling basis.

• Rolling margin helps in analyzing the profitability of a product over time.

• It is calculated by subtracting the cost of goods sold from the selling price and dividing by the selling price.

• For example, if the cost of goods sold is $50 and the selling price is $100, the rolling margin would be 50%.

Rate analysis involves calculating the cost of different items in a construction project, such as masonry works.

• Rate analysis helps in determining the cost of materials, labor, and equipment for each item in a project.

• It involves breaking down the total cost into components like material cost, labor cost, equipment cost, and overheads.

• For masonry works, the rate analysis would include calculating the cost of bricks, cement, sand, labor, and other associated costs.

• Rate analysi...read more

IS code for measurements in site is IS 1200-1:1992

• IS 1200-1:1992 is the code for measurement of buildings and civil engineering works

• It provides guidelines for taking measurements and preparing bills of quantities

• The code covers measurement of earthwork, concrete, brickwork, steelwork, and more

• It also includes rules for rounding off measurements and calculating quantities

• Adherence to IS 1200-1:1992 ensures accuracy and consistency in site measurements

Concrete quantity for trapezoidal footing

• Calculate the volume of the trapezoidal footing

• Multiply the volume with the density of concrete to get the weight

• Divide the weight by the unit weight of concrete to get the volume of concrete required

• Add 5-10% extra concrete for wastage and spillage

Material estimate for concrete, mortar and unit weights.

• Calculate the volume of concrete needed based on project specifications

• Determine the mix ratio of concrete (e.g. 1:2:4 for cement:sand:aggregate)

• Calculate the weight of each material based on unit weights (e.g. 150 lbs/cubic foot for concrete)
