Relative Cost Ratio/Index Method This is another interesting and novel method of calculating capital cost developed by author during his experience over the years. This is based on the concept that relative cost of any plant and equipment; industrial products remain constant and fixed over the period of time for any place or country. For example, relative cost of a bicycle, scooty and car will be same irrespective of time and place. Similarly, relative cost ratio of a three-phase motor and matching gear box and coupling is a constant not affected by time or place. Similarly, relative cost ratio of one Million Tonnes (MT) steel plant & four MT steel plant is constant (Not necessarily linear). Similarly, ratio between 1000 MW Thermal Power Plant with 1 MT steel plant, Cement Plant is constant for a place at any time. By knowing the cost of one the cost of other can be easily calculated. Engineer shall work out these ratios and use them for the calculation of capital

Erection Considerations It is seen that if proper erection sequence and methodology is not followed, it may result in time and cost overrun, duplication of jobs, dismantling & re-erection, accidents, loss of life and property. Therefore, this is also one of the main basic consideration which every engineer/entrepreneur must be aware of. The following erection considerations shall be taken into account 1. Erection Sequence 2. Erection Methodology 3. Special Requirements/OD consignment, Before building roof erection, 4. Minimizing Erection Time. In situ erection (THF Example) 5. Temp Protection Requirements 6. Erection of Cranes-Tower Cranes, Jib Cranes, Hydra, 7. Batching Plants-Capacity & Number 8. Alignment, lining, levelling & grouting 9. Inserts Placements (Requirement to be checked at design stage) 10. Rate of RCC per day, per Month 11. Rate of fabrication per month at sit
