Explain the factors that affect rate analysis. ## Short answer Rate analysis requires drawings, material/labour rates, norms, equipment data, wastage, overhead, and site data. Factors affecting it are lead, material and labour availability, specifications, quantity, construction method, climate, time, and contractor's overhead. ## Answer #### Requirements of rate analysis 1. **Drawings and specifications** of the item (to know the dimensions, quality and method). 2. **Material rates:** local market rates and the District Rate of the materials, with the transport (lead) and loading/unloading charges. 3. **Labour rates:** wages of skilled and unskilled labour from the District Rate, and the labour productivity. 4. **Norms:** the standard consumption of materials and labour per unit of work (DUDBC norms for building and sanitary work, Department of Roads norms for road work). 5. **Equipment data:** hire or running cost of machines, with their output. 6. **Wastage allowances** and conversion factors, such as dry volume of mortar and compaction factors. 7. **Overhead, profit and tax:** contractor's overhead and profit (15% in the DUDBC norms), VAT 13% and any royalty or insurance. 8. **Site data:** lead, lift, location and conditions of the work. #### Factors affecting rate analysis 1. **Location and lead:** distance from the source of materials to the site (lead) and the lift; remote hill districts have a high transport cost. 2. **Availability and price of materials:** local or imported materials, royalty, taxes and market fluctuation. 3. **Labour:** wage rates, availability of skilled labour and productivity (output per day). 4. **Specification and quality:** mix proportion, grade, thickness and finish required. 5. **Quantity of work:** a large quantity lowers the unit rate through economy of scale. 6. **Equipment and method of construction:** manual or mechanical, the cost of machines, fuel and operators. 7. **Climate, season and site conditions:** rain, altitude, access, difficult soil or water, working space and height of work (lifting). 8. **Time of completion:** a short time needs more resources and overtime. 9. **Wastage and norms:** the standard wastage allowance and the consumption norms of the department. 10. **Contractor's overhead and profit, taxes** (VAT) and insurance, and the mode of payment and contract conditions. ## Check yourself The answer's key points as multiple-choice questions, with the correct option and why. 1. Which is a requirement for preparing a rate analysis? A. Only the contractor's quotation B. Only the bank interest rate C. Soil test report only D. Drawings and specifications, material and labour rates, norms Answer: D. Specifications, District Rates, labour rates and norms are needed. (Key point: Requirement) 2. Which allowances are needed in rate analysis? A. Wastage allowances and conversion factors such as dry volume of mortar B. Seismic factors C. Load factors D. Safety factors of steel Answer: A. Wastage and conversion factors (dry volume, compaction) are required. (Key point: Conversion factors) 3. What is the effect of remote location on the rate? A. Lower material cost B. High transport cost due to long lead C. No effect D. Lower labour wages Answer: B. Remote hill districts have high transport cost. (Key point: Lead) 4. How does a short completion time affect the rate? A. It lowers the rate B. It removes overhead C. It needs more resources and overtime, increasing the rate D. It does not matter Answer: C. Faster work needs more resources.
