Study Notes
Cost Accounting and Financial Reporting
- The level of accuracy required for cost accounting and financial reporting influences the chosen allocation method.
- Factors influencing cost allocation include accuracy and precision requirements, available data, and management preferences.
Rate Analysis Concept
- Determine the unit of measurement for each material (e.g., cement in bags, steel in kilograms, bricks in numbers, aggregates in cubic meters, and timber in cubic feet).
- Estimate quantities required for each material based on project specifications and drawings.
- Calculate the unit rate for each material by dividing the total cost by the total quantity.
- Multiply the unit rate by the estimated quantity to find the total cost for each material.
Illustrative Calculations
- Cement: Unit = Bag (50 kg), Estimated Quantity = 500 bags, Unit Rate = Rs.100 per bag, Total Cost = Rs.50,000
- Steel: Unit = Kilogram, Estimated Quantity = 10,000 kg, Unit Rate = Rs.20 per kg, Total Cost = Rs.200,000
- Bricks: Unit = Number, Estimated Quantity = 50,000 bricks, Unit Rate = Rs.3 per brick, Total Cost = Rs.150,000
- Aggregates: Unit = Cubic Meter, Estimated Quantity = 200 cubic meters, Unit Rate = Rs.400 per cubic meter, Total Cost = Rs.80,000
- Timber: Unit = Cubic Feet, Estimated Quantity = 5,000 cubic feet, Unit Rate = Rs.24 per cubic foot, Total Cost = Rs.120,000
Bar Bending Schedule (BBS)
- A BBS is a detailed reinforcement list that provides information about the type, size, quantity, and placement of reinforcement steel bars in a reinforced concrete structure.
- Developing a BBS involves:
- Understanding structural drawings and design specifications
- Identifying structural elements and marking reinforcement requirements
- Calculating reinforcement quantities and checking against standard codes and specifications
- Grouping and summarizing reinforcement data
- Utilizing software tools and creating bending shapes and dimensions
Understanding cost accounting and rate analysis concepts, including allocation methods and unit of measurement estimation.
