After part payment of Rs.120.00 Lakhs (including deduction of TDS & Education Cess) towards supervision charge the petitioner requested OPTCL to review and re-examine the sanctioned estimate, as the estimate amount of Rs.12,01,87,600/- was considered to be on higher side for a line of 7 Km and its bay as the total value of the project considering all the costs was found to be Rs.7,41,74,111/.
