“The claimant has worked out compensation amount based on the formula given in clause 10 CC in Annexure F/1 and F/2. However, the amount paid in claim No. 1 at market rates is not eligible for increase in cost and has to be deducted. Modified statement for compensation on analogy of formula in Clause 10 CC has been prepared and is attached at Annexure E. This works out to Rs. 17,39,412.00. Another way to look at escalation in prices is building cost index which is published by DG, CPWD every six months. Building cost index of Delhi as on 01/04/2010 was 136 and that on 01/10/2012 it was 170 based upon Plinth Area Rates of 2007 as base 100. Thereafter it remained constant upto 01/10/2013. Thus there is almost 25% increase in construction costs during relevant period, which in the present case would work out to approximately Rs. 65,00,000.00 and after deducting amounts of escalation calculated under Clause 10 C (Labour) and 10 CA (Cement and Steel) it gives a figure of about Rs. 30,00,000.00 which is much more than the amount worked out on the basis of formula under clause 10 CC. In view of above I conclude that Rs.17,39,412.00 as worked out above would be a reasonable
