Western I ndonesia National Roads I mprovement Project 20
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 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. To date, detailed engineering design for fifteen 15 sub-projects has been completed, four 4 are
under final review with respect to highway engineering and road safety audit and detailed design works of two 2 sub-projects are still pending due to proposal to replace the two 2 originally listed
packages. As previously reported in previous Monthly Progress Report of November 2014 CTC conducted the
final review with respect to highway engineering and road safety audit wherein detailed report for each of the four 4 sub-project drawings were prepared and forwarded to PMU.
The four 4 detailed drawings were submitted to World Bank for their review and issuance of No Objection Letter NOL.
However, based on Bank s review some comments were noted. The comments will be considered and incorporated the necessary correction prior to resubmission to
World Bank . The final detailed engineering design drawings for the four 4 sub-project that were finalized
by BALAI II and reviewed by CTC and World Bank are follows :
• Package 7 : Indrapura Tapan
• Package 8 : Bts. Pariaman Manggopoh
• Package 10 : Sp. Empat Sp. Air Balam
• Package 12 : Kambang Indrapura
With regards to the preparation of the other four 4 drawings, the designer, DSC have completed the detailed design drawings and were submitted to BALAI II for final review and approval. The final
review will be jointly conducted by Balai II, CTC, DSC and TLKJ in Padang. The completed DED drawings are for the following sub-projects :
• Package No. 14 : Painan Kambang
• Package No. 16 : Seblat Ipuh
• Package No. 20 : Lubuk Alung Sicincin
• Package No. 21 : Lubuk Alung Kuraitaji

As mentioned earlier, there is a proposal to delete two 2 originally listed packages for implementation under AWP-2 and AWP-3 due to the two 2 listed sub-projects were recently
rehabilitated with newly laid asphalt concrete overlay on the existing travelledway. The sub-projects that are originally listed for implementation in the WINRIP Program and proposed to
be replaced are are Package No. 9 Rantau Tijang Kota Agung and Package No. 18 Mukomuko Bts. Sumbar both located in Lampung and Bengkulu, respectively.
The candidate roadlinks that are considered and proposed as repalcements are Biha Bengkunat Link No. 028 and Sibolga Sorkam Link No. 043 both located in Lampung and North Sumatera,
respectively. One 1 of the two 2 proposed road sections which is Biha Bengkunat is already included in List of Proposed Links For Feasibility Studies on Report from the Technical Assistance of
Project Preparation for WINRIP but updating of economic evaluation still to be conducted. While the other proposed roadlink Sibolga Sorkam which is not included in the original List of Proposed Link
For Feasibility Studies needs economic evaluation to determine whether it is feasible for further implementation.
A Technical Analysis Report For Verification of Replacement Road was prepared by the CTC s Co Team, Highway Engineer and Road Safety Audit Engineer from data and informations gathered
during the reconnaissance and preliminary surveys and was formally submitted to PMU. Based on the final review by PMU of the Technical Analysis Report For Verification of Replacement
Road, the Directorate of Planning endorsed the proposal to World Bank for the Bank s confirmation and issuance of No Objection Letter NOL.
In principle, the World Bank thru letter ref. no.WINRIP187 interpose conditional No Objection to the proposal by DGH to replace the original road sub-projects by two 2 new road links as follows :
a the two 2 replacement roads will be subjected to evaluation of technical and economic point of view by the World Bank and subsequently to restructure the project with loan agreement
to change the road section. b DGH to confirm the willingness to fully or partially finance the civil works with ABPN budget in
case World Bank s technical and economic evaluation are not satisfactory and or the loan closing date is not extended.
Progress of Technical Design Review and Road Safety Audit are shown in Appendix B.
4.2 Procurements
Procurement shall be conducted under the Bank s Procurement Procedures as mentioned in the Loan Agreement. The International Competitive Bidding ICB based on the Bank letter Ref. WINRIP136 will
apply to the packages with the construction estimated cost more than US 25 Million to comply with the new Bank s threshold for ICB. According to the GOI regulation, a prequalification shall be applied for the
packages with the construction estimated cost more than IDR 10 Billion. Review from previous procurement process, the World Bank in the Aide Memoire requested to GOI, for next 4 ICB subprojects
qualification still used Pre-Qualification and for remaining sub-project must be process with Post
