What are the requirements for analysis of rates? ## Short answer Rate analysis provides unit rates for estimating, material/labour needs, tender evaluation, and cost control. It requires drawings, material and labour rates, consumption norms, equipment data, wastage allowances, overhead/profit, and site data. ## Answer #### Significance of rate analysis in civil projects 1. Gives the **unit rate** of every item, which with the quantities gives the cost of the project. 2. Gives the **consumption of materials, labour and equipment**, for procurement and scheduling. 3. Provides a sound basis for **tender evaluation**, and for judging abnormally low or high bids. 4. Helps to price **extra items and variations** fairly. 5. Allows **comparison of alternatives** (materials, methods, mix proportions). 6. Helps in **cost control** during construction, and standardizes the rates in the government departments. #### Requirements for 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. ## Check yourself The answer's key points as multiple-choice questions, with the correct option and why. 1. Which is a significance of rate analysis? A. It gives the unit rate of each item and helps evaluate tenders and price variations B. It replaces drawings C. It removes need for estimates D. It fixes the design loads Answer: A. Unit rates with quantities give the cost; also used for tender evaluation and variations. (Key point: Significance) 2. Which norms are used for building and sanitary work vs road work? A. DoR for buildings, DUDBC for roads B. DUDBC norms for buildings/sanitary, Department of Roads norms for roads C. IS codes for both D. NBC for both Answer: B. DUDBC covers building and sanitary; DoR covers road work. (Key point: Norms used) 3. What overhead/profit and VAT are normally taken? A. 10% overhead, 15% VAT B. 5% overhead, 13% VAT C. 15% contractor's overhead and profit, 13% VAT D. 15% overhead, 5% VAT Answer: C. DUDBC norms use 15% overhead and profit and VAT is 13%.
