rate analysis of pcc (plain cement concrete)

Rate analysis of Plain Cement Concrete (PCC) is a critical process in construction, involving a comprehensive assessment of costs associated with the construction of concrete structures without reinforcement. PCC is commonly utilized in foundational work, flooring, and various non-structural elements.

pcc

Plain Cement Concrete, refers to a blend of cement, fine aggregates (like sand), and coarse aggregates (such as gravel), combined with water. This composite material finds extensive application in construction projects, serving roles in foundational work, flooring, and other non-structural components. Distinguishing it from reinforced concrete, PCC lacks the inclusion of reinforcing elements like steel bars. Its principal function lies in establishing a sturdy and enduring foundation for subsequent construction endeavors.

considerations for Rate Analysis

Materials

Cement: This includes the cost per bag or unit.
Fine Aggregate (Sand): Assessment of cost per cubic meter or ton.
Coarse Aggregate (Gravel): Evaluation of cost per cubic meter or ton.

Labour

Mixing and Pouring: Comprising the cost of labor required for the mixing and pouring of concrete.
Finishing: Encompassing the cost of labor for the surface finishing of the concrete.

Equipment

Concrete Mixer: This involves the cost associated with renting or operating a concrete mixer.
Vibrators, Trowels, etc.: Incorporates the cost of any specialized equipment used during the process.

Transportation

Transporting Materials: This section focuses on the cost of transporting cement, sand, and gravel to the construction site.

Miscellaneous

Water: Includes the cost of water used in the concrete mix.
Admixtures/Additives: This accounts for the cost of any additives used for achieving specific properties, if applicable.

Overheads and Profit

Overheads: Encompassing costs associated with administrative expenses, insurance, and other relevant expenses.
Profit Margin: This represents the percentage of profit added to cover business expenses and profit margin.

Contingencies

Contingency Fund: Allocation of a percentage of the total cost for unforeseen expenses or changes in the project.

Total Cost

The summation of all the aforementioned elements provides the overall cost for the PCC work.

rate analysis pcc

Given,

pcc volume = 3m^3

mix ratio = 1:4:8 (cement : sand : aggregate)

material rate analysis

Quantity

wet volume = 3m^3

dry volume = 1.54*3 = 4.62m^3

sum of ratio = 1+4+8 = 13

cement quantity = (1/13)*4.62*(1440/50) = 10.235 ~ 11bags

sand quantity = (4/13)*4.62*35.32 = 50.21cft

aggregate quantity = (8/13)*4.62*35.32 = 100.42cft

cost

Rate Assumptions:

cement/bag = ₹ 500

sand/cft = ₹ 12

aggregate/cft = ₹ 15

Amount

cement = 11*500 = ₹ 5500

sand = 50.21*12 = ₹ 603

aggregate = 100.42*15 = ₹ 1506

Total Cost = 7609+5500 = ₹ 13109

Add 1.5% water charges of total cost = 196.63 ~ 197

Add 10% contractor profit = 1310.9 ~ 1311

Grand Total = 13109+197+1311 = ₹ 14617

For 3m³ PCC = ₹ 14617

Rate for PCC work will be 14617/3 = ₹ 4872/m^3

Note

It is imperative to acknowledge that rates and costs can vary based on factors such as location, availability of materials, labor rates, and specific project requirements. Therefore, consulting with local contractors or utilizing current market rates is crucial for an accurate rate analysis.
