Final Engineering Designs, Engineer s Estimates and bidding documents have been completed for all projects proposed for WP-1. WP-2 nine subprojects and WP-3 eight subprojects will be designed by DSC and the construction supervision of all the works programs will be performed by the same DSC team. In parallel with the instruction to speed up the process, detailed engineering design DED of some subprojects of WP-2 and WP-3 were prepared and completed by respective P2JN. The CTC has been instructed by DGH to review the DED of seven packages completed by the P2JNs package 5, 6, 11, 13, 15, 17 and 19.
