Final Substantial Completion Inspection Report: Qanjogha Canal

A Substantial Completion Inspection (SCI) was conducted on December 30-31, 2019, and submitted to the United States Agency for International Development (USAID) on January 16, 2020. The SCI identified deficiencies, including leaky and difficult to operate steel gates, unfilled construction 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 to repair the defects after the intake was blocked and the canal had dried up. The Final Substantial Completion Inspection (FSCI) was requested by the Strengthening Watershed and Irrigation Management (SWIM) contractor and was held on September 17, 2020. The SWIM contractor's subcontractor had rectified all the deficiencies reported in the SCI report. Tetra Tech (Tt) Engineering Support Program (ESP) observed a hydraulic test and the modified gates had decreased the water leakage to an acceptable quantity, per American Water Works Association (AWWA) standard. The SWIM contractor and his subcontractor have resolved all of the deficiencies reported on the SCI punch list, and Tt ESP did not uncover any additional issues in the FSCI. Completion and rectification of punch list deficiencies are documented in Appendix A and the SCI punch list photo log (Appendix B). The Qanjogha canal rehabilitation project is part of the SWIM Program, a United States Agency for International Development (USAID) project designed to increase agricultural productivity through irrigation and watershed development and enhanced management. The 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 project. The joint walkthrough inspection covered the entire 2,000 meters of the canal, 45 turnout structures (38 one-way turnouts and 7 two-way turnouts), and one aqueduct, as well as one community water access point (CWAP). The inspection was conducted on September 17, 2020, and representatives from Tt ESP and the SWIM contractor met to inspect the site, the canal, and other associated structures and verified the completeness and the rectification of deficiencies. A total of 10 deficiencies had been identified in the original SCI, and the SWIM contractor's subcontractor had rectified all deficiencies, detailed in both Appendices A and B. During the FSCI, it was observed that all 10 deficiencies had been rectified and closed. Additionally, eight Non-Conformance Reports (NCRs) were issued during construction, and as of the date of this report, six NCRs were closed, and one NCR was issued for the four canals and is currently under review by Tt ESP.
