SAPMT has reviewed the subject submittal dated March 30, 2014 and has the following comment:

•	The submitted cable sizing calculation does not show the voltage drop calculation if the proposed size of power cable, (120 mm sq.) can carry the required ampacity for a long run of loop distribution system. As discussed during SAPMT/IC/SCEC meeting dated Feb. 9, 2014, SAPMT/IC/SCEC conference call dated March 10, 2014 and progress meeting # 28 dated March 31, 2014, IC is urged to provide 3/c x 185mm2 cable with package substations as stated in the bid package. Package Substation shall constitute an RMU, Distribution Transformer and LV Power Panel which is not possible with the pad mounted Transformer. Furthermore, 185 mm sq. Power cable is suitable for termination to the load break switch of Ring Main Unit (RMU). It is to be noted that the award of contract is based on the bid package and IC shall refrain from lowering the specifications without providing adequate technical justifications.
