Abstract
A Substantial Completion Inspection (SCI) was conducted on December 24, 2019, and submitted to the United States Agency for International Development (USAID) on January 18, 2020. The SCI identified deficiencies, including leaking and difficult to operate steel gates, unfilled joints, and improper backfilling around an aqueduct. Due to the onset of the planting season and the need for irrigating the fields, it was decided that the defects found could only be repaired once the intake was blocked and the canal had dried up, which would not occur until after the planting season. The Final Substantial Completion Inspection (FSCI) was requested by the Strengthening Watershed and Irrigation Management (SWIM) contractor and was held on September 16, 2020. The SWIM contractor's subcontractor had rectified all the deficiencies reported in the SCI report dated January 18, 2020. The main issues of leaky and difficult to operate steel gates, openings without water control elements, and unfinished construction joints have been suitably rectified. Tetra Tech (Tt) Engineering Support Program (ESP) observed an improvised hydraulic test of the steel gates since there was no water in the canals at that time. The modified gates decreased the water leakage to an acceptable quantity per the American Water Works Associations (AWWA) standard. True hydraulic testing will not occur until later in the year when water returns to the canal and be properly tested. The purpose of this report is to document the completion of the Jalal Abad canal, including the results of the FSCI and the status of identified deficiencies. The FSCI team found that all deficiencies had been resolved during the joint walkthrough inspection of 4,740 meters of the canal, including 240 m extension of stone masonry canal lining, 47 turnout structures, and 21 turnout openings. A total of 29 deficiencies had been identified in the original SCI. Tt ESP's inspectors did not uncover any additional issues. Completion and rectification of punch list deficiencies are documented in Appendix A and the SCI punch list photo log (Appendix B). The SCI was conducted on December 24, 2019, where 29 deficiencies were reported. During the FSCI, it was observed that 29 out of 29 deficiencies had been closed (rectified). The SWIM program is a USAID project designed to increase agricultural productivity through irrigation and watershed development and enhanced management. The SWIM program focuses on the rehabilitation and expansion of existing irrigation schemes, improvement of on-farm water management, restoration of watersheds to secure water reliability, and strengthening of institutional capacity for irrigation and watershed management at both national and local levels. Tt ESP was contracted to provide construction management support and quality assurance (QA) to the SWIM program. The joint walkthrough inspection included representatives from SWIM and Tt ESP, who verified completeness and rectification of deficiencies on September 16, 2020. The SWIM contractor's subcontractor had rectified all the deficiencies reported in the SCI. A total of 29 deficiencies had been identified in the original SCI. Tt ESP's inspectors did not uncover any additional issues. Completion and rectification of punch list deficiencies are documented in Appendix A and the SCI punch list photo log (Appendix B). During the project, Tt ESP issued six Non-Conformance Reports (NCRs) to the SWIM contractor for failed concrete tests, improper backfilling, and Health & Safety (HS) issues. As of the date of this report, NCR-0002-HS is closed, and NCR-0007, 0008, 0009 are closed, and NCR-0012-QA was closed administratively by Tt ESP. NCR-0013-QA was issued against four canals and is currently under review by Tt ESP.
