Western I ndonesia National Roads I mprovement Project 14 4 CIVIL WORKS

4.1 Detailed Design Preparation

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 DSC. During the CTC mobilization, the DSC has not been established yet. 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 indicative work programs and cost estimates identified for WP-2 and WP-3 are subject to verification, and are likely to change following more detailed investigations. Further preparation for WP-2 and WP-3 will be managed by the PMU supported by the CTC. Detailed design of selected links for WP-2 and WP-3 subprojects will have been approved by DGH. Those final engineering designs shall meet the same quality standards and specifications, in terms of detailed content and presentation, as those prepared and approved for WINRIP WP-1 shown at Table 4.1 Table Revision of Scope of Works for Design WP 2 – WP 3 Table 4.1 Revision of Scope of Work for Design WP 2 – WP 3 Pack.

However, in parallel with instruction from DGH encouraging P2JNBBPJN to carry out the Detailed Engineering Design DED until DSC is established. The CTC will then conduct necessary check and review on completed Detailed Engineering Design DED prepared by the DSC with steps as shown in Figure 4.2 below. Figure 4.2 Process of Check and Review on Completed DED Considering the WINRIP procurement plan, the Highway Engineer has started Technical Design Review in advance. Package No.5 Sp.Rampa – Poriaha is reviewing. The Senior Highway Engineer will be mobilized on 1 February on schedule. Progress of Technical Design Reviewing up to the end of January 2013 is included as Appendix B.
