Monthly QA Report No. 2: WO-LT-0082 AMD 3 - American University 200-Bed Women’s Dormitory

Budget information contained herein is for illustrative purposes. All policy, personal, financial, and procurement sensitive information has been removed. The main construction activities during the reporting period from July 2, 2016, through July 28, 2016, included excavation, backfilling, compaction, testing, steel reinforcement, and formwork for sewer piping and manholes. Additionally, excavation, backfilling, compaction, testing, steel reinforcement, and formwork of electrical utility handholes and manholes were performed. Placement and curing of concrete manhole bases, replacement of unapproved backfill material in utility trenches with approved fill, and placement of cable trench conduit were also completed. The major issues impacting construction progress during this period included the use of unapproved backfill for sewer utility. A Non-Conformance Report (NCR) was issued to the contractor regarding this issue, and Tetra Tech recommended that the unapproved backfill material be removed and replaced with material that met specifications. The contractor began replacement of the backfill with approved material on June 27, 2016, and completed the replacement by July 11, 2016, with the exception of the material under bases MH-1 and MH-2. Another Non-Conformance Report (NCR) was issued for the performing backfill between manholes MH1 and MH2 without insulating sewer pipes. Tetra Tech recommended that the contractor remove the backfilled material between MH1 and MH2 and insulate the sewer pipes with approved insulation material. Perez lifted the bases of manholes MH-1 and MH-2 by crane, removed the unapproved backfill material, compacted the soil base of the manholes, and performed FDT testing for the bases of the manholes on July 16 and 18, 2016, respectively. The contractor performed construction work on this project prior to approval of required pre-construction plans, including the Health and Safety Plan, Quality Control Plan, Environmental Protection Plan, and Security Plan. The contractor believed that these plans were approved by USAID, but Tetra Tech did not review and approve them. Work performed during the reporting period included the installation of well casing and pump, well seal, well test (compressor), and well test (pump test). The contractor completed 100% of the well casing and pump installation, well seal, and well test (compressor) but only 50% of the well test (pump test) due to pending test results. The pump test for the water well was completed at the site, and test results were being generated by the laboratory. Tetra Tech received a total of 74 submittals from the contractor, with 26 approved as submitted and 41 rejected and requiring re-submittal. The average length of time for Tetra Tech to process a submittal was 11.08 days, and the average length of time for the contractor to return a rejected submittal to Tetra Tech was 35.95 days. The project's status of in-progress site activities showed that the well casing and pump installation, well seal, and well test (compressor) were completed, while the well test (pump test) was 50% complete. The vault excavation was 70% complete, and the vault base compaction and preparation were 10% complete. The cumulative percentage of work completed was 80%, and the balance percentage was 20%.
