## Question

Prepare a bill of quantities from the following data for the construction of an RCC T-beam decking bridge.

| Quantity of work | Detail of work | Rate per unit of work |
|---|---|---|
| 108 m³ | PCC (1:1:2) for RCC works | Rs 13,200.00 |
| 3240 m² | Formwork for RCC works | Rs 750.00 |
| 21600 kg | Steel reinforcement for RCC works | Rs 115.00 |
| 18 m³ | PCC (1:2:4) wearing coat | Rs 12090.00 |

## Short answer

Bill of quantities lists each item with unit, quantity, rate and amount; amount equals quantity times rate. The T-beam decking works total Rs 6,557,220.00, comprising PCC Rs 1,425,600, formwork Rs 2,430,000, reinforcement Rs 2,484,000 and wearing coat Rs 217,620.

## Answer

A bill of quantities lists each item with its description, unit, quantity, rate and amount (amount = quantity x rate).

| SN | Description of work | Unit | Quantity | Rate (Rs) | Amount (Rs) |
|---|---|---|---|---|---|
| 1 | PCC (1:1:2) for RCC works | m³ | 108 | 13,200.00 | 1,425,600.00 |
| 2 | Formwork for RCC works | m² | 3,240 | 750.00 | 2,430,000.00 |
| 3 | Steel reinforcement for RCC works | kg | 21,600 | 115.00 | 2,484,000.00 |
| 4 | PCC (1:2:4) wearing coat | m³ | 18 | 12,090.00 | 217,620.00 |
| | **Total** | | | | **6,557,220.00** |

Working of the amounts:
- PCC for RCC: 108 x 13,200 = 1,425,600.00
- Formwork: 3,240 x 750 = 2,430,000.00
- Reinforcement: 21,600 x 115 = 2,484,000.00
- Wearing coat: 18 x 12,090 = 217,620.00

**Answer: Total cost of the T-beam decking works = Rs 6,557,220.00.** Contingency and VAT are added to this total if required.

   A. Rs 243,000
   B. Rs 2,430,000
   C. Rs 3,990
   D. Rs 24,300,000
   Answer: B. 3,240 x 750 = 2,430,000. (Key point: Formwork amount)

3. What is the total cost of the T-beam decking works?
   A. Rs 6,339,600
   B. Rs 4,127,220
   C. Rs 6,557,220
   D. Rs 6,775,200
   Answer: C. 1,425,600 + 2,430,000 + 2,484,000 + 217,620 = 6,557,220. (Key point: Total)
