Summary: Clearing of spoils from the blockages by re-mining commenced in H1 was continued with adequate caution keeping safety adherence at highest priority during H2. Out of the 6 major rock falls / full collapses in various sections of the Head Race Tunnel (HRT) and 2 full collapses (which were earlier thought to be one collapse) in the Skhalta Didachara Transfer tunnel (SDTT), four blockages in HRT and both blockage Locations in SDTT were cleared in H2. A comprehensive program of further detailed inspections, investigations and rock testing was continued to confirm and verify the geological features of the rock strata in various sections of the tunnels to ascertain the required remedial support works. The Civil Contractor, AGE had continued to augment its equipment and manpower in H2. Work was carried out on several fronts in the HRT and SDTT in parallel. MML also continued its investigation & supervision during this period. In view of this detailed investigation & repairs in the HRT & SDTT Tunnel, it was decided to extend the investigation also in Chirukhi - Skhalta tunnel with opening of work front in Skhalta outlet section. As of date, the program of investigation and testing is in progress with significant part of the HRT having being already inspected and many test results on several rock samples have been received. Further inspections in the SDTT have been carried out as blockage was cleared and water drained from major part of the 9 km tunnel. During this period, AGL has also engaged the services of 3G (Austria) for onsite supervision and Prof Luiz De Mello to advise AGL by reviewing MML’s assessment of the root cause and the proposed remedial design. A workshop was conducted in September 2018 during which MML presented further updates on potential causes of the failures observed and learnings while clearing the collapsed areas. The same was discussed in details while emphasizing the primary importance of health and safety aspects. The final design for the support work is reviewed and finalized after receipt of a major portion of the results of geological tests. It is envisaged that the tunnel repair works shall be completed by the second quarter of 2019, with the finalisation of support structure design and extent of tunnels to be repaired in all the three sections of Tunnels. Below is a summary of construction works for the reporting period: Civil Works: The civil works remaining in Skhalta, Didachara & Shuakhevi PH have been continued to complete attending to Punch lists, and reach handover stage. Tunneling Works: All tunnels in the project have been de-watered and inspected. - Didachara - Shuakhevi HRT & HPHRT Works have been taken up for Stage 2 Repairs. (S2R) Access at Chanchkhalo was established in Oct 2018. - Repair works in the SDTT started in Oct 2018 and access from Intake side was also established in Nov 2018. - Minor repair works at intermediate stretches of Chirukhi-Skhalta Tunnel commenced from Skhalta side in Oct 2018. As of end of December 2018, the status of inspection was as follows: 4 Figure 1 Status of Repairs & Inspection Only two major blockages at the chainage 11900 and chainage 4200 remains to be cleared. While the blockage at chainage 11900 is expected to be cleared in January 2019, the blockage at chainage 4200 will take longer and expected to be cleared by end-March or m-d-April 2019. Didachara dam area: Didachara reservoir was drained and no water was stored in the reporting period as access to Skhalta - Didachara Tunnel Outlet section was established and work continued. Road construction on the downstream side of Ghorjomi bridge has been completed and procedure to handover this with joint inspection in consultation with the Roads Department of Georgia is advancing as planned. Skhalta dam area: Skhalta reservoir was drained and river water is now flowing through flood discharge tunnel to facilitate inspection and attending to repairs in Skhalta - Didachara Tunnel. Skhalta Power House: Chirukhi to Skhalta tunnel is also drained and access plug dismantled at Skhalta outlet side. The E&M contractor, CKD, has demobilized and will be back at site after the tunnel is filled and the 35 kV line is nearing completion. Until such time CKD has provided preservation plan for the equipment in power house which is being taken care by AGE (under AGL supervision), weekly checks being carried out as per the plan. As part of this plan, CKD carried out manual rotation of the units and inspected various instrumentation signals. It is expected that the commissioning activities of the Skhalta power house shall start by July 2019 after completion of 35 KV transmission line and Chirukhi - Skhalta Tunnel Repairs. Chirukhi Weir: Weir construction is complete and Radial Gates on weir & Desander flushing gates remain open to pass the river flow. Ghorjomi Bridge: Bridge and approach road works are complete. 5 Diakonidze Weir: AGL has carried out a water balance study for the Diakonidze stream. E-flow assessment has been suspended for now and will be restarted after full funding is made available for the Project. The assessment will be presented to the E&S teams of lenders before moving forward to the scheme. Based on the joint consensus on the approach, work will start, and adequate monitoring system will be put in place. Possible alternatives to explore transfer of Ghorjomi stream water to Didachara Reservoir or transfer the water in the HRT is being evaluated by desk study. These will be reviewed and taken up once the clarity on funding is available. EM Works: Preservation and maintenance activities are being carried out as per plan submitted by GE and AGL's maintenance plan. Work on attending to punch list related to Shuakhevi by AGL is underway. Subsequent to the runner inspection by AGL, MML, GE, Norconsult and SWECO, it is envisaged that repair works would be required on the Runner to address pit marks. Discussions with GE are in progress. Gap analysis review has been carried out to identify infrastructural requirements for Operational readiness. GE representative has demobilized from site in Dec 2018. Skhalta commissioning discussions with CKD, GE and MML have commenced. 35 kV Transmission Line: Out of total 133 towers, 75 foundations and 66 towers were completed in H1 before works were suspended. AGL lifted work suspension of 35kV transmission line on the 22nd October 2018, AGL and NMG started working on documents to be submitted to municipalities for obtaining a construction permit from Shuakhevi and Khulo Municipalities. The Annex to the LALRP for the condemned house located in the buffer zone between towers 112 and 113 has been prepared and submitted to lenders E&S team for approval. There may be route change in Furtio village. AGL will develop Addendum to LALRP and undertake archaeological screening prior to commencing construction activities. All documentation and compliances related to HSE checklists will be taken up with supervision by AGL once work re-commences 6 3. Compliance evaluation: Was the Company in material compliance with (i) environmental and social (E&S) requirements of the Lenders (ADB, EBRD and IFC), including the "Environmental and Social Action Plan" (Schedule 12 (Form of Action Plan) of the CTA), (ii) environmental, health and safety regulations, standards, and permits of the host country?
